A Context for Asset Management

Another example from a 2018 buildingSMART Award winner for Construction is “Project Pontsteiger”. Digital engineering models provided offsite manufacturing so that no cutting and drilling on site would occur. Digital demand models were developed to look at all disciplines to a level at which production could participate in making their own supply models. For each discipline within the demand models, a production partner was brought in. BIM coordinators were appointed onsite, coordinating and checking all models and working together with the site engineering team who were responsible for the program, 2D output and contracts. By coordinating teams, and utilising BIM models as a decision-making context, the teams were able to make better decisions before any onsite construction, helping to deliver on-time and under budget.

These project delivery examples provide better understanding of the digital context for planning to construction. The need go beyond BIM deliverables will offer fruitful outcomes if new sources of data can be connected. A digital twin needs continuous data inputs. This is not an easy task. Data alignment and mapping are needed with data standards and templates that can add layers and attributes to data so that the digital twin knows that a door is actually a door, and the specifications of that door are accurate and manageable. If the information in a digital twin is inaccurate it is rendered useless. One example that this has worked well in is the use of barcodes for asset recognition, giving the digital twin precise information about the asset. This also helps to link a new network of product manufacturers who can provide relevant information about an asset or component ac ca.

A Context for Asset Management

A context for asset management is where many feel a digital twin will deliver the most value. The long-term benefit for a digital twin is the potential in asset reliability, integrity and performance. If AI, machine learning and automation can be applied to digital twins then decisions about assets could soon become seamless. Getting to this utopia, however, is more of a challenge. For example, today, companies have a major challenge in managing change and synchronizing changes to apply advanced analytics for better decision-making. This is primarily because data is not aligned and often inaccessible for performance benefits.

One such example of a digital context that delivers asset management benefits is in the project by Minnucci Associati s.r.l. and their winning project from the 2018 buildingSMART Award category for Operations and Maintenance. By developing a common data environment (CDE), the project could house over 12,500 components and 44 federated digital models to create asset information models. These models connect to the existing work order management system to help make better decisions when operating Naples Station. The station itself has over 400 operational trains and a variety of public shops and spaces, therefore a context for helping run the facility was critical.

(Minnucci Associati developed digital models from laser scans to help operations and maintenance of Naples Station in Italy)

The key benefit of this project was to provide a context to manage change. A digital twin needs to change and adapt to be effective. To make decisions in real-time via a digital twin requires a multitude of data to be made available in a 3D model. There is no doubt that the software is there today. Open source platforms are available on GitHub for users to trial and add their own expertise to. This is an exciting opportunity and probably the real value-add for digital twins – the ability to adapt, change and maximize the potential of digital workflows for better decision making. The opportunity for owner-operators is better lifecycle planning by making projects open and accessible. Only then will we be digitally twinning.

buildingSMART hosted a roundtable on “Digital Twins” with Siemens at the International Standards Summit in Dusseldorf on 26th March 2019. Amongst the attendees, it was universally agreed that a pilot project would be hugely beneficial for the industry. buildingSMART is looking forward to leading the way on the development of an open standard for a digital twin.

Revisiting the differences between CIMA and ACCA (2017 version)

During this time, both competitors for the hearts of financiers - both CIMA and ACCA - have changed, updated and improved. Yes, I am too. In a sense, if it has not been updated and improved, then at least after a couple of written textbooks on CIMA P1 and P2, I can compare in detail not only my favorite line of subjects in IFRS , but also how in ACCA and CIMA management accounting and financial management have been submitted .

In general, since everything is different and everything is different, I decided to update that old comparison of mine. Below is a new summary picture: accp certification

To be honest, it has become easier to compare. After CIMA shoveled its program in 2015, redistributing topics between the subjects of the curriculum in a new way, I succeeded in what I could not do 7 years ago: to make a comparison by subject. Although now there are still cases when what is collected in ACCA in one subject is scattered over several CIMA subjects, and vice versa. I also showed it in the table.

But the most interesting thing is that the key findings from today's qualifications comparison are the same as those of 7 years ago:

There is much more in common in the qualifications of ACCA and CIMA than differences : both in the content of the subjects and in the depth of examination. Therefore, if you are determined to gain a career advantage in finance with a financial qualification, the key is to get some kind of qualification.

CIMA, to a greater extent than ACCA, works on general management disciplines (people management, marketing, stakeholder management, etc.), which accounts for almost a third of the program (line E1-E2-E3). In fact, in the context of our educational reality, this line duplicates part of the standard university program in business management. Therefore, only with a slight stretch it can be said that  CIMA "educates" a manager who owns the tools of a financier .

ACCA, to a greater extent than CIMA, focuses on finance itself, taking a deeper and deeper look at a specific set of financial instruments: from advanced financial management to understanding the external audit process. That is, ACCA “grows” a financier who understands how business works .

In principle, all this is reflected not only in the self-positioning of each qualification, but also in their names. It is known that the name of both qualifications uses the word "accountant", which - and this is important - in the Russian equivalent is much closer to the word "financier" than to the word "accountant". Only ACCA is just an Association of Chartered Certified Accountants , that is, just a "financier" , and CIMA is a Chartered Institute of Management Accountants , that is, "a financier from management," literally translated. The conclusions from my comparison only confirm this difference in names.

Okay, you ask - what will the resume be? Where to go?

My answer is evasive: it all depends on your specific situation. In general, both qualifications make a financier better and smarter in a number of ways. Both qualifications claim global coverage. That is, in terms of career advantages, both CIMA and ACCA will give you a lot. But one of them is more financial specific (ACCA), and in the other - more managerial specific (CIMA). Now decide what you personally need more, taking into account what kind of education you have, what are your career preferences and professional preferences.

That seems to be all. But before leaving, I will clarify for those who are not aware that, in addition to subject differences, ACCA differs from CIMA in the method of testing knowledge and skills. For example, exams in each individual CIMA subject are shorter - only one and a half hours versus the standard three-hour exams in ACCA. But between the CIMA levels there are large case exams covering as many as three subjects at once (E1-P1-F1, for example). But we will talk about this difference in testing some other time.

Teleworking: between constraints and advantages

A new study finds 36% of companies were not ready to support the abrupt, large-scale transition to remote workforce imposed by COVID-19 measures. However, many of them believe that teleworking could become a "norm"

The pandemic caught many professionals by surprise who were faced with a more or less degraded way of working. The study by Navisite, a UK cloud computing provider, indicates that half of the professionals surveyed experienced IT difficulties during the transition process acca certification.

More seriously, a third admits that they are still facing problems. Almost a quarter (24%) admit that only some of their dysfunctions have been resolved. 5% say that kidney has not been fixed ...

Among the potential obstacles, respondents point out in particular the poor connection to the home of teleworkers (especially when teleworking and distance education occur simultaneously) in 49% of cases, the increased risks in terms of security and compliance ( 46%), neglect of employees in their homes or inappropriate use of company devices (20%) and lack of staff resources to manage the large number of remote users (13%).

“This rush to set up teleworking could potentially make organizations' IS vulnerable. These threats must be corrected both to protect the integrity of their infrastructure and to ensure their compliance with various regulations, insists Karyn Price.

For this senior analyst at Frost & Sullivan, “Desktop-as-a-Service (DaaS) and Workspace-as-a-Service can provide secure access to company data and services and they can be deployed, configured and centrally managed. This allows the company to ensure that security and compliance profiles and appropriate access restrictions are maintained, and that data is not stored on local, or even personal, endpoints that are not protected 

Despite all these fears and obstacles, many organizations believe that working remotely could become the "new normal". For companies, the arguments in its favor are the productivity and efficiency of employees but also the reduction of costs in terms of office space and maintenance.

 In Linux The Administrator Account Is Called Top 

What Directory Under/Contains The Log Files And Spools For A Linux System? 

After A Shell Is No Longer Needed, What Command Can Be Given To Exit The Shell? in linux the administrator account is called top

RECOMMENDED:Do you have at least two? Need to erase or eliminate an administrator account in Windows 10? In this guide, we will perceive how to erase or eliminate an administrator account in Windows 10.Deleting a head account is as straightforward as erasing a standard client account. Notwithstanding, you have to sign in as an executive so as to erase an overseer account.When you erase an administrator account, all information spared in that record will be erased. For example, you will lose your records, pictures, music and different things on the work area of the record. 

Exit What Directory Under/Contains The Log Files And Spools For A Linux System? 

Client organization in Linux. Two of the most significant duties of any manager are the organization and observing of clients on a Linux organization. Great premonition with respect to a framework director will forestall pointless personal time and will reveal security openings before they become an issue. Dec 2, 2018 - Linux Login as Superuser - Explains how to turn into a superuser in Linux utilizing. The superuser, or root, is a unique client account utilized for framework. Under Linux (and other Unixish working frameworks) you use order called su. That you are attempting to run the comand as the super client or director,. 

Along these lines, it's a smart thought to back up all information from the record to another area. Here is the means by which to erase a manager account in Windows 10.NOTE 1: You have to sign in as a head so as to erase an overseer account. At the end of the day, you can't erase or eliminate an administrator account from a standard client account.NOTE 2: You can't erase or eliminate the administrator account which you have right now marked in. To eliminate the record which you have at present marked in, kindly (in the event that you have only one administrator account), sign in to the new administrator record, and afterward erase the current one.NOTE 3: Deleting a record will likewise eliminate all its information from your PC. All things in work area, reports, music, pictures, and downloads will be erased. 

In the event that the information is significant, kindly back up them before continuing further.Method 1 of 1 Delete an administrator account by means of SettingsStep 1: Open Settings application by all the while squeezing Windows logo and I keys on the keyboard.Step 2: In the Settings application, explore to Accounts Family and different records. On the off chance that you are on Enterprise version of Windows 10, kindly explore to Accounts Other accounts.Step 3: Here, you can see all administrator just as standard client accounts. 

As said previously, the record which you have at present marked in doesn't show up in the rundown here. For example, on the off chance that you have two administrator accounts "A" and "B" on your PC, you have to sign in to account "A" to erase administrator account "B."Step 4: Click on the administrator account which you need to erase or eliminate. 

Snap the Remove button.Step 5: When you see the accompanying affirmation exchange, click Delete record and information catch to erase the record and all information from the account.Method 2 of 2 Delete administrator account by means of Control PanelStep 1: Open Control Panel. Change View by to Small symbols. 

After A Shell Is No Longer Needed, What Command Can Be Given To Exit The Shell? 

Snap User Accounts.Step 2: Click Manage another record connect to see all client accounts on the PC.Step 3: Click on the administrator account which you need to erase or remove.Step 4: Click Delete the record link.Step 5: When you see the accompanying affirmation discourse, either click Delete Files or Keep Files button. On the off chance that you click the Keep Files button, Windows consequently spares the information of the record in an envelope on your present work area before erasing the account.Hope this makes a difference! As of late, my logon scrren demonstrated my email address. This email address has become the executive in spite of the fact that I have not set up a manager account which would require having a secret word and thusly, there are numerous progressions I can't impact because of this lockout. The interest for overseer/secret key is just a case in which chairman sections can't be made at any rate. How my email transformed into an overseer is a marvel and my nearby record at the same time became secret key secured itself with no access of one from me. Any activities almost, require an overseer's authorization for even thesimplest matters. 

As the sole client, I have a pin for signin and no secret phrase was set for the neighborhood account. My screens have become a snap of blue and yellow manager's consents. It is highly unlikely I can change my nearby record by any stretch of the imagination. My other issue is that ifmy email address is eliminated, will that influence my email account, my essential email account too?

What is NetFlow: a network protocol developed by Cisco Systems

Web applications, blogs? You need web monitoring tools!

In French the word "present" has two meanings: the present, this moment that you are reading this article, or a gift among others. There is no confusion here, but the adjective "free" can mean free, without cost, and free, that he has freedom. Today we will see several free applications that you can use as web monitoring tools system administrator tasks.

Web server monitoring

What are we looking for in web monitoring tools? What is a web server?

It is a computer or device capable of offering information or data by means of a protocol (or securely by HTTPS). For your supervision, we consider two main areas: internal supervision and external supervision.

In the internal part, there are three crucial points:

General state of your Web server: load, disk space, temperature of the components (if not virtual), ie the basic values ​​of any server.

Web traffic: open connections, listening, addresses, etc.

Information in the logs : it is very important to configure, since you have several domains on the same web server, each with its independent file.

For external supervision :

Simple tests: if it is online, response time, certificates expiration (if using HTTPS), etc.

Transactional web monitoring: it monitors the processes that respond to a series of steps. The simplest example is if a user can connect to your web server (say you have a simple blog with WordPress installed).

Pandora FMS

If you are a new reader of our blog, here is a surprise: the free version of Pandora FMS is able to work with the 3 points of internal supervision (by means of software agents) and the first point of external supervision!

Can't you believe it? I explain to you.

You can find more information on everything that has been described so far at this link .

You are probably using a web server with Apache: for this specific case we have a great article written by the creator and founder of Pandora FMS.

The network management (local or extended) indirectly participates in the Web supervision.

After using Pandora FMS and / or some of the web monitoring tools shown here, you can perform web optimization , since the performance of web applications has become a key element for the proper functioning of organizations.

Web monitoring tools

I come back to the subject of free or "free" applications: the web monitoring tools that I include also have more permissive licenses, like the one from MIT or the same Apache license, or more restrictive such as the free ones. Since this is a very broad subject, Wikipedia collects a large number, if not all.

Another type of web monitoring tool that I must name is the one offered as a physical service from different parts of the world. Although some are free programs , it is obvious that there is a monetary cost to maintain virtual or real machines all over the planet, so that they regularly access your website from so far away and let you know.

With these explanations, let's now see the web monitoring tools.

Only

Yes, you yourselves, as programmers, can use "real user supervision," placing specific instructions before and after your code does read and / or write operations on your web server, then by keeping an additional journal. Later, we'll see its counterpart, User Experience ( UX ).

I must also mention the figure of the "poor man": on the CodeProject site there is a tool with a personalized free license which indicates how to work practically by hand (I do not recommend this method, I include it only for educational purposes).

Linux Dash

I consider it the lightest, but don't be fooled by appearances. It has been created in a minimalist but versatile way: you can use Go, Python or Node.js languages, because surely some of these working environments are already installed on your system. This way, you don't add a load just to install a web monitoring tool.

What is NetFlow? Well I know what you are thinking, what comes to your mind every time you go to one of those articles trying to define a computer concept: “Ufff, doesn't it seem like all of them computer concepts compete with each other to appear complicated? They almost sound like forced names of energy drinks. "" NetFlow gives help ""

What can we say about it? To me, they would have names that sound like Elvish, but there's nothing we can do. Today we are going to explain: "what is NetFlow?" We've already ruled out the energy drink, and just in case you're wondering, it doesn't refer to isotonic drinks or a lost brand of sporting goods.

What is NetFlow? Definition

Okay, Netflow is just a network protocol developed by Cisco Systems (a company that was founded in 1984 and is considered one of the biggest companies in the tech industry today). Netflow is designed and used to collect information about IP traffic . He's getting further and further away from your idea of ​​an energy drink, eh? Netflow is so popular that when in the industry they refer to one of the many other versions that exist with the same mission, they also call it Netflow. Even if they are not part of the brand. As you know, this is the case with industrial glue. It doesn't matter what brand it is, it's often called Loctite. O with the dolls: “Daddy, buy me a Barbie”.

Supported by the Cisco Routers and Switches Compendium, NetFlow allows devices to collect information. What kind of information? Well, this information that comes from the traffic that goes through the links. After that, it then sends this traffic information to a device called the NetFlow Collector , using User Datagram Protocol (UDP, a transport level protocol based on the exchange of datagrams).

There are many ways to measure and charge for information on IP networks. Cisco simply offers the NetFlow protocol, which is supported by multiple router models from the same company. Netflow only obtains this information from the flows that make up the traffic through said devices.

NetFlow was introduced as a new feature in Cisco routers to gain the property of collecting IP network traffic when entering or exiting an interface. Once you have the data on the table (“on the table” is a way of speaking, since we are not talking about scrolls or maps) the data acquired through NetFlow can be analyzed. A good, experienced network administrator can infer or infer keys such as where traffic is coming from or where it is going, possible triggers for congestion, or types of service.

Cisco NetFlow v5 , the most standardized Cisco NetFlow, defines flow as a unidirectional sequence of packets that share the following characteristics:

Input interface

Source IP address

Destination address

IP protocol

Source port for UDP or TCP

Destination port for UDP or TCP, type and code for ICMP

IP service type

The Cisco brand, along with v5, also has NetFlow v7, v9 and v10 ; they add more values ​​than those mentioned here and which extend their description.

What is NetFlow? Some applications

Among all the possibilities of NetFlow, we can take advantage of its use for accounting or invoicing . It provides us with all kinds of detailed information, from IP numbers, types of ports or services, schedules… to the number of packets in circulation. Being able to operate with all these types of resources can give us a lot of flexibility and maneuver in accounting. We can change the rate types by taking advantage of our data. For example, from a flat rate to more ductile joints that are installed during the hours of the day, the use of bandwidth, applications, devices, service.

One of the best ways to use all the information provided by Netflow is to improve the design and optimize the analysis of your networks. Create a policy for routers and their actions, recreate the backbone, develop strategic network engineering plans minimizing operating costs, increase performance, capacities and resources, etc.

Of course, now that we have answered the question "what is NetFlow?" », We can move towards network supervision. Imagine the possibilities that NetFlow can offer you, because with it it is quite possible to monitor everything that is happening on the network. NetFlow-based study strategies allow us to analyze parameters related to particular routers, switches or network traffic and their applications. All of this can help us avoid problems by preventing actions and finding possible breakdowns, before anyone else.

Besides, do you know who benefits like no one else and is a champion of this last point, supervision? Of course Pandora FMS . It is flexible monitoring software capable of monitoring devices, infrastructure, applications, services and business procedures.

LINUX SYSTEM ADMINISTRATOR / SECURITY

contrast between PC designing and software engineering

 PC Engineering and Computer Science – Similarities and Differences 

Understudies considering a vocation fixated on PCs and figuring frequently request explanation about the distinction between PC designing (CEN) and software engineering (CS). There are philosophical just as pragmatic responses to these inquiries. Both CEN and CS study the utilization of the computerized PC as an instrument that makes conceivable a lot of present day innovation and the cover between the two fields is noteworthy. The two orders study the internal activities of PCs and both examination equipment just as programming parts of PC frameworks. The distinctions are those of accentuation. Understudies in CS, CE, or Electrical Engineering will all investigation programming and fundamental PC activity. 

Software engineering is generally more difference between computer engineering and computer science worried about the hypothetical underpinnings of calculation and of programming; subsequently one commonly discovers courses in programming, calculations, mathematical examination (how would you ensure a number delivered by a PC program is precise), and the hypothesis of calculation (what can and can't on a basic level be registered) in Computer Science divisions. Numerous CS offices at U.S. colleges were branches from math offices during the 1970s, and the accentuation on giving a thorough numerical establishment to the figuring disciplines is as yet apparent in numerous CS educational plans. 

PC designing projects to a great extent created in designing offices solid in electrical designing. PC Engineering centers around the useful parts of advancement and utilization of PCs. Courses in computerized rationale plan and processor interfacing which expand on a designing understudy's information on hardware and circuits are regularly found in CEN programs. At the convergence among CEN and CS are courses in PC design (the essential development and low-level programming of PCs) and working frameworks, which are as liable to be found in either or the two projects. 

At UMaine, Computer Science is a division in the College of Arts and Sciences, while Computer Engineering is a program inside the College of Engineering. Software engineering majors follow the Arts and Sciences educational plan while Computer Engineering majors follow an Engineering educational program. The contrast between these two degrees is the distinction between the two universities: the point of science is to extend a fundamental information on a particular field, while the point of designing is to consolidate advancement and innovation. 

PC engineers fabricate equipment while PC researchers by and large don't. Nonetheless, PC researchers positively think enough about equipment to examine PC framework tasks and to connect with equipment engineers. PC researchers find out about fundamental hypothesis of calculation, programming dialects, and working frameworks. 

While PC designs frequently function as developers, most framework level projects, for example, programming dialects and working frameworks are planned by PC researchers. Notwithstanding, PC designs typically compose the projects for PC based frameworks. 

Since designing is the utilization of the standards of essential science to the taking care of issues inside requirements (that is, building things!), PC designing is designing applied to PCs and PC based frameworks. All in all, PC engineers construct PCs, for example, PCs, workstations, and supercomputers. They likewise manufacture PC based frameworks, for example, those found in vehicles, planes, machines, gadgets, telephones, correspondence organizations, and many, numerous different items. PC designs ordinarily plan the equipment, yet in addition a great part of the product in PC based frameworks.

PC designing, INFORMATION TECHNOLOGY and software engineering are for the most part teaches inside a similar domain of study. In any case, every strength centers around explicit parts of the field, and professions inside the three regions differ significantly. 

Difference between computer science and information technology

Software engineering 

PC researchers are, actually, researchers. They are engaged with the hypothesis of computational applications. That implies they comprehend the "why" behind PC programs. Utilizing calculations and progressed arithmetic, PC researchers imagine better approaches to control and move data. PC researchers are commonly worried about programming, working frameworks and execution. 

Like Neo in The Matrix, PC researchers can see and sort out code. Software engineering understudies will become familiar with the essentials of various programming dialects, straight and discrete arithmetic, and programming plan and improvement. PC researchers study the machine itself and see how and why different PC measures work the manner in which they do. 

Basically, PC researchers can converse with PCs. The field is situated in mathematicsäóîthe language of PCs. PC researchers comprehend why PCs work and can make a program or working framework that does what you need it to do.

PC Engineering 

To put it gruffly, PC engineers make PC parts cooperate. PC engineers are liable for the exploration, plan and improvement of PC gear like circuit sheets, central processor, switches, video cards, and so on A few colleges may regard this order as an off-shoot of electrical designing. 

It is valuable for PC architects to have a grip of software engineering. PC designs regularly manage equipment to-programming coordination, which means they need to plan and fabricate processors and equipment that can uphold a given program. As innovation progresses and our gadgets become littler and littler, a principle objective of PC engineers is to make computer chips and microchips that work financially and proficiently. 

PC designing understudies will examine ideas in software engineering, designing and arithmetic. By joining these three fields, PC engineers can tackle equipment issues and make best in class machines that can deal with the numerous errands PCs perform.

What is impulse current?

Surge current is a sudden increase in current, usually caused by voltage imbalance. In general terms, a jump is a sudden increase, and an electric current is the rate of flow of a charge. Current is usually measured in amperes (A). If the DC power cable (20 VDC) carries 20 A during sustained load, the current surge can be about 50 A during transients such as when the power is turned on. Voltage imbalance is an electrical potential difference that causes current surges.

What is computer engineering

There are many ways to avoid equipment failure due to surges. This current can be internal or external. The surge current generated internally is usually the result of a capacitor surge current that occurs when a capacitor or capacitor is pre-discharged, followed by a sudden current flow that is designed to equalize the capacitor voltage in the source circuit.

Note : the link can be used to buy a voltage stabilizer for the home to protect household appliances from power surges.

External surge current usually comes from lightning. Despite attempts to protect sensitive equipment from lightning strikes, there is always the possibility that such currents could be induced on live equipment. Live equipment may have power supplies and other cables, such as interface cables and signal cables, that carry radio frequency, audio, or data.

In RF systems, the antenna, usually on an antenna tower elevated above the ground, is always where the signal strength is best. The same ideal location for listening to a radio frequency signal is where lightning is most likely to occur. Lightning rods are placed at the highest point of these towers to catch most of the lightning strike, but some of the surge energy gets into the electronic equipment.

Lightning is one of the potential causes of power surges.

Surge protection devices available on the market include surge protection devices and surge protection devices. Equipment rated at 110 VAC (VAC) can withstand the voltage surge causing the input voltage to rise to a maximum of approximately 150 VAC. Surge protection devices are also available for all types of signals. These include RF surge protectors as well as audio and data surge protectors.

Predicting surge current is also important to keep electronic and electrical equipment functioning. Circuit designers must anticipate all possible surge conditions in order to build reliable equipment. These transients can overload circuit components to the point of complete or partial failure.

What is computer engineering for?

Computer engineering is the process of analyzing and designing all hardware, software, and operating systems for a computer system. It is a combination of two fields: computer science and electrical engineering. Computer science and engineering are often confused as the same thing, but the two areas are very different. Although the responsibilities of computer scientists consist largely of electrical and software development, computer engineers are also trained in software development and the integration of hardware and software computer science vs computer engineering salary.

Computer engineers are also focused on computer networks. They should use their knowledge and understanding of the design of logic and microprocessor systems, as well as computer architecture and computer interface. In the course of their work, computer engineers can find answers to basic computer problems by creating the following great technological solution.

Case Western Reserve was the first university to offer a computer engineering program in 1971; however, there are now over 100 accredited universities in the world. Students who wish to pursue a major in this area must have a deep knowledge and understanding of mathematics and science. If a student excels in these subjects, computer engineering is likely to be a good fit for them. Computer engineers also need to have a clear focus on detail, teamwork, and analytical skills. Good communication skills are also required because computer engineers often have to go outside the laboratory to deal with clients and other professionals.

The field of computer engineering is broad, but there are many smaller areas that most students focus on. Sometimes, a person who is studying to be a computer engineer chooses a major with an emphasis on computer architecture or the way information is organized within an organization. Other possible areas of study are database systems, operating systems, or software development. If the student chooses to study any of these or other fields, he will bring a specialized advantage in the field of computer science.

This area is constantly growing and changing due to the rapid pace of technological progress. Therefore, it is important that professionals constantly improve and master new things in order to keep abreast of all new developments. Computer engineers are often required to attend training seminars created by vendors, hardware and software manufacturers, colleges and universities, or other private institutions.

At some point, computer engineering branches out in two directions. The professional must decide whether he or she wants to focus on the technology side of the field or pursue a career that combines technology and management. If the latter option is chosen, he must continue his education with additional courses in business and finance and an MBA may be required.
