Advantages and Disadvantages of Computer Based Training

Computer based training is a fairly new approach to training but many people are finding that they enjoy it a lot more than more traditional methods. If you enjoy traditional methods then you may think that there is no point in trying a new method but you may be surprised that it is better for you. If you struggle with traditional methods then this could be a solution for you.

There are obviously advantages and disadvantages to it, as there is with anything else and it suits some people better than others. If you are trying to decide whether to do a CCNA CBT then it is important to find out exactly what it will involve and that will give you a good idea as to whether this style of course will suit you. Of course the only way to really find out is to actually do a CBT course and find out.

However, you should be able to find out what is involved and you may even get to see some of the CCNA training videos that they have so that you can judge whether it is a style that suits you. They may have some sample clips or excerpts that you can download and watch which could be useful. It is usually pretty easy to try out and you should be able to tell fairly quickly as to whether it is something which you think would work for you.

You may find that there are several different companies offering the same sort of training and so it is a good idea to look at several and see which looks to be the best. This should not take too long and it will help you to choose the best possible course for you and your needs. Many people think that once they decide that they are going to do a CBT course they choose the first one that they come across but it is very important to do some research and make sure that you are making a wise choice so that you get the best one. It may seem tiresome and it is probably not that exciting a thing to do but it may be the difference between a pass and a fail and so it is important to make the right decision as you do not want to have to sit the exam again because you have made a poor choice.…

6 Serious Article Writing Deficiencies, and 6 Ways You Can Fix Them

As a writer and editor of The Digital Camera Zone, I spend hours every day scouring the ezine barns for articles to put in front of an information hungry public.

I definately find a lot of articles, all right. They number in the thousands. Because I need content to feed a voracious audience, I select as many as I can even though I'm often not really happy with many of them.

"Why," I can hear you ask, "do you publish articles that you are not happy with?"

Well, the answer lies in several unfavorable shortcomings in many of the articles published in article barns …


Many articles are glaringly wonderful. The author may start with a good promise, say, the need to research out digital cameras before buying the one, but then drops the ball.

In essence, the only thing the article says, in 500 – 600 words or so, is "Do your homework".

– There are no concrete suggestions as to how to do the research.

– There are no suggested sources where the reader can go to find information.

– There are no criteria by which the reader can decide which camera is best for her.

In short, the article may not as well have been written. The writer is merely telling the reader what she already knew and provides no real information. Remember: it's not "content that is king¨; it's quality content that is king.


Just about every article on writing articles for the web emphasizes that your creation should be "rich" in the keywords your readership is inputting into the search engines.

The trouble comes when you try to include all of the right keywords in your article so that people will find and read it. The danger is that you actually degrade the content of the article and make it less useful.


There's nothing that attracts a reader more quickly to an article than a short story, anecdote or personal experience that identifies her with the subject.

This anecdote or short story should be based on experience, either your own, an acquaintance, or a plausible situation, and should confront the reader with a problem, immerse her in a dilemma, or invoke an emotion that directly leads to the solution posed by The article.

Many article writers start firing facts at the reader and doggedly go on in the same paragraph to advance the solution, without really building up the reader's curiosity or expectations.


Many writers, when they decide it's time to pump out their daily (or minute-ly) articles, sit down and write paragraph after paragraph until the word count reaches 850 words or so without any discernible organization to their work.

Then they stop, and fire it off.


We load up the article with long paragraphs which exhibit no …

The Purpose of Anti-Virus Software

Anti-virus software is software that you install on your computer so that you can be alerted when you have a virus. Anti-virus software will help to keep your computer safe against worms, viruses, Trojan horses, and other uninvited programs.

The software can also help you clean your computer if you should happen to have a virus. The important thing to remember about anti-virus software is that you make sure to update it often so that you get the latest computer virus definitions installed into the software program. There is no point in having the anti-virus software if you’re not going to update it. You’ll be able to get updates from the vendor that sold you the anti-virus software, such as Norton.

Many times you may already have anti-virus software on your computer in which case you be sure to uninstall it before installing your new software. To find out if you have virus software check under your Start menu to see if you one listed, such as McAfee or Norton. Keep in mind that just because you have anti-virus software already installed on your computer that it (1) might not be working, and (2) hasn’t been updated for a long time.

Once you’ve installed anti-virus software on your computer you’re going to want to make sure that you use it correctly. Make sure that the settings in your computer automatically turn the anti-virus software on when you boot up your computer. You always want to be protected. If you’re downloading something off the Internet your anti-virus software will let you know if there is a problem.

You can also use the anti-virus software to specifically scan any downloads, or files, that that have been sent to you via e-mail. If you are alerted that you have a virus your software will guide you with the right steps to removing it. Make sure that you don’t continue to use your computer until the virus, or worm that you have, is removed. You don’t want to send e-mail to friends and help in the spreading of the virus.…

Importance of Electronic Technology

We have taken steps on the road to the future that can not be retaken or undone. The importance of electronic technology is now ingrained in every fiber of our society, from the lowest station all the way to the coveted office of the President of our country.

Importance of electronic technology flourishes with abandon, doubling upon itself every fourteen to twenty-four months, constantly becoming that which we won’t do without, thanks to the growth of technology. Time-consuming tasks that once took hours, even days, are now accomplished in minuets.

Computers and the Internet provide various new methods which have been incorporated for the processing of normal business activities, growing bigger and being customized to the point where it is heavily integrated in the current structures.

Without the Importance of electronic technology, routine tasks that now only take moments, thanks to the computer, would otherwise have taken hours, even days for the compiling of information alone.

The Importance of electronic technology in communications is where news is most called upon. As one of the fastest developing industries in the world, the cell phone has revolutionized the way we live and communicate with each other and the world.

Everyone wants to be informed when a new innovation in the cell phone industry is unveiled. The addition of the internet, as well as GPS navigation systems, sent the communications industries staggering to the bank under the weight of the money being made.

Technology in the Health-care system alone has had long reaching effects. The speed and storage ability of computers has simplified and increased the efficiency of the record keeping systems, this being only the tip of the technological iceberg.

Many hospital systems connect entire departments, from their doctors to the accounting departments, pharmacy, and billing. All use a system called HIS. HIS is a (hospital information system). HIS is software used by all hospitals and integrates most of their departments.

I believe inroads in the field of electronic technology in the Education System need to be explored more extensively. The outrageous cost of a good college education borders on the realm of criminal larceny.

By placing for some an unattainable price on the education of their choice, the educational system is stealing not only their futures, but depriving society of their potential contribution.…

4 Important Features For Buying a Desktop Computer

For most non-techie people buying a computer is confusing and frustrating. With all the terms, features and functions that one needs to consider and understand it often becomes a hassle that few want to deal with. For the basic user, who just wants a computer for Internet, email and word processing there is no need for bells and whistles. Basic features will be enough to get the job done. But, if you are looking for a computer for entertainment, gaming or business you will need more intricate features that will provide high performance.

Getting acquainted with some computer terminology and having a basic understanding of the most important computer features is important and can assist you in getting the right computer, the first time.

1. Processor or CPU

CPU stands for central processing unit; it is the brains of the computer. In terms of computing power, the CPU is the most important element of a computer system and the speed, which is given in GHz, and quality of the processor will greatly determine the performance of the computer.

There are budget, mid range and high-end processors. The one that you need will depend on what the computer will be used for.  Often times you can get a nice high-end processor that is no longer manufactured for the same price of a brand new budget processor.

For basic computer functions, such as email, Internet and word processing a budget or mid range model is fine. But, for gaming, and especially 3D gaming, video editing and processing, movie watching and for some business functions a high-end processor is necessary.

High End Processors:

The high-end processors are top of the line and will cost quite a bit. An interesting fact is that while these processors cost twice as much as the mid range types they perform only about 25-50% better. Today, the top of the line processors are: Intel Core 2 Extreme QX9650 and Higher, Intel Core 2 Quad Q9650 and the Intel Core i7 Extreme 965.

2. RAM Memory

RAM memory refers to the amount of programs you can run on computers without running into slow downs, crashes and drags in performance.

The more RAM the better as it greatly affects the speed and performance of the computer, especially for video, entertainment and gaming. 1GB is good for most computer functions, 2GB, 3GB and 4GB is really great. At least 2GB, but 3GB and 4Gb is better for the optimal gaming and media experiences.

It is a good idea to check and make sure that there are open memory upgrade slots so you can always add more memory RAM, it is fairly cheap and easy to install.

3. Ports and Connections

Ports are the connections that come with a computer for attaching peripherals, such as such as printers, Internet/Ethernet, iPods, scanners and others. One of the most important and useful ports is the USB, which the computer should have at least 4 of.

Other useful ports are Ethernet for high speed Internet …

3D TV Technology Has Plenty Of Applications

Three dimensional TV, or 3D TV as it will undoubtedly come to be called, is sure to become a winner when it comes to market in the future. This futuristic way of watching TV has been envisioned for years. In fact, it’s a rare science fiction scenario that doesn’t anticipate some kind of holographic or three dimensional entertainment or communications technology.

3D TV has a lot of practical uses for a lot of different people both professionally and personally. For example, the applications to diagnostic medicine are pretty obvious. After all, a two dimensional X-ray could never compare to viewing a scan of someone’s innards from any angle when it comes to figuring out what’s wrong with them. Three-D scans could take the guess work out of a variety of different types of surgery by allowing doctors to look at wounds, tumors, foreign objects, broken bones, and blockages before even opening a patient up. Plus, when combined with real time scanning technology that’s already available, 3D TV could even allow doctors to look at the physical processes of living people in real time!

The applications for physicists, scientists, and engineers could also be extremely useful. Much like doctors could do with humans, zoologists could look at the inner workings of exotic, even possibly endangered animals, without dissection. Physicists will be able to use the technology to analyze complex processes that would be extremely difficult to conceptualize in two dimensions. Engineers will be able to do similar things with the technology in order to visualize the things that they’re building and designing. If you think about the extremely small applications of nanotechnology, you can see how 3D TV could be extremely useful for the development of that technology as well. After all, with most other mediums people can look at their prototypes.

One of the first forms of entertainment that will benefit from 3D TV will be video gaming. That’s because most modern video games generate their images in 3D and then convert them to two dimensions for display on a computer screen or a TV screen. This means that it would take only minor changes to how video games work in order to display a huge number of them in 3D.

Creating TV programming in three dimensions is a little more difficult, but several well known directors are working on 3D movies right now. There’s also software under development that converts 2D video into 3D images that can be shown on prototypes of 3D TV sets. The software still has a lot of bugs that need to be worked out. While it does convert 2D programming to 3D programming, it doesn’t render the images very realistically. At least one version of the software that’s been developed so far is that it can be run on hardware that’s widely available. In fact, a laptop computer was able to run prototype software without any trouble.

While we can’t be completely sure how 3D TV will play out- especially when it comes to …

What Does Software Engineering Involve?

The first point that has to be made about software engineering has to do with its scope of activities. Software engineering is the management of the entire process of development of computer systems to solve problems.

As software systems have grown more sophisticated and complex, software developers have sought new methods for their development. Software engineering is a response to that need. Software engineering is still rapidly changing and maturing.

Typically, when someone is told to write a program, someone else has told him or her what the program is to do and why; the programmer is concerned only with how to write it. As software engineers, however, we will be the ones concerned with the what and why. Software engineering includes the whole range of activities having to do with problem solving – from helping the client define the problem or opportunity, to evaluating the client’s satisfaction with the solution.

Developing a software system may require writing a whole collection of programs to tell machines what to do, writing procedures to tell people what to do, and providing training so that people understand how to do it. We may need to convert data from an old system so it can be run by a new system, hire people and acquire machines to run the programs, and obtain space in which the machines and people can do their work. What we are building is a system of many parts working together. Such an endeavor requires patience and flexibility. We will have to fix the system when it does not do what we expected, or the client may ask us to change the system because he or she wants it do something else not previously intended.

Programming may be no more than 20 per cent of the total scope of software engineering, and the fraction of effort involved with programming can be expected to drop as improved methods are used for developing software systems. As time goes on, more of our effort will go into managing the overall process and less into programming.…

The History of the Car Computer

The car is a very complicated thing in the modern world, with a whole host of mechanical and electronic systems working together to keep the car running, and to keep its levels of operation at maximum efficiency. The engine control unit is the centerpiece of a car’s electronics, which makes millions of processes each second to make slight adjustments to the actuators depending on the information the central CPU gets from the various number of real-time sensors. This goes alongside the transmission control unit, which ensures that gear changes within automatic cars are most efficient. These car computers not only keep the car running, but minimize the amount of fuel wasted, which keeps efficiency and economy high, whilst helping to protect the environment with minimal emissions.

The cars of today present a marked contrast between now and the early days of the automobile. From the turn of the century when the first commercial automobiles emerged, to the end of the 1960’s, there were obviously no electronic components, and vehicles were designed simply and included simple and robust mechanical control parts and basic methods of control. Back then a better car meant a car with a bigger engine, more speed and more horsepower, and little heed was paid to efficiency, economy, and the environment. However, the issue of the environment, and certainly the issue of economy became more and more pronounced in the 1970’s, with the inclusion of mandates, and the notable fuel crisis of the mid 70’s.

Around the same time, electronic technology was reaching the point where it was physically able to be included in automobiles, alongside the transmission from carburetors to fuel injection, but is wasn’t until the 1980’s that electronics became practical and economic enough to be included. Control over the ignition in the interests of minimizing fuel usage drove car electronics. The first pieces of circuitry used to control spark timings where large pieces of solid state circuitry, and would need replacement every few years. By the middle of the 80’s, the industry would be founded on fuel injection completely controlled by electronics.

Naturally, as commercial electronics boomed in the 80’s and on through the 90’s, becoming smaller, cheaper and more sophisticated, on-board car computers would take on more and more functional responsibilities, sensing more and more data and controlling more and more aspects of the car engine, among other things such as braking and climate control. Indeed it was not long before the computer became the central and integral component in the car.

With the rise of the computer came the potential for customization, with access to a programmable computer providing immense control other a vehicle’s power and other variables.…
