What Are the Different Types of Computers?

These days, computers are described using many different terms. In most cases, simply the capability, the expected use or the size of the computer is implied. However, what most of us do not know is that there are actually different types of computers.

Types of Computers

1. PC

A computer designed to be used by a single person is defined as a personal computer (PC). While a Mac is a personal computer, systems running the Windows OS are considered PCs by most people. Initially, personal computers were referred to as microcomputers because they were complete computers with a smaller size. The Apple iPad is a perfect example of a modern PC.

2. Desktop

A desktop computer is a personal computer that is not designed to be portable. Generally, desktop computers are set up in permanent locations. In comparison to portable computers, more versatility, storage and power is offered by most desktop computers for a lesser price.

3. Laptop

Laptops, also known as notebooks, are small-sized portable computers can be placed on the lap and used there. The display, hard drive, keyboard, memory, processor,

The Ways That Renting a Computer Will Save You Money

If you are looking for ways to save money, computer rental is definitely something that you should consider. Not only is it far cheaper to rent a computer than to buy one outright, you can also save yourself money on finance charges, upkeep, maintenance and the headaches involved with owning a brand new laptop or personal computer.

12 Ways Renting a Computer Will Save You Money

There are so many ways to save by computer rental instead of purchasing laptops or a desktop computer that it would be difficult to list them all here. However, the following twelve ways that you save by choosing computer rental should give you an idea of the kinds of savings you are looking at.

  • Renting a computer is cheaper. Instead of having to come up with hundreds or thousands of dollars out-of-pocket, you can spend a set amount every month.
  • When you rent a computer you don’t have to worry about the pesky finance charges that so often come attached to computer credit accounts. All the costs are in your monthly rental fee.
  • Computer Rental is better for the environment. By recycling computers you can cut your carbon footprint on the

Best-Paying Computer Degrees

Beating all odds stacked against them, computer degrees seem to have regained favor with students. At least that’s what the data released by the Computing Research Association (CRA) suggests.

According to the CRA Taulbee Survey report, Computing Degree and Enrollment Trends, 2010-11, enrollments in undergraduate computer science degree programs rose 9.6 percent in the 2011-12 school year. This was the fourth straight year of increased enrollments in computer science degree programs*.

The increase in demand for computer degrees among students indicates a corresponding growth in computer-related careers that can be monetarily rewarding, personally fulfilling, and intellectually stimulating. Here’s a selection of some computer degree programs and the careers they can lead to:

1. Computer Science Degree: The computer science degree has been ranked among the top ten undergrad college programs by salary in a 2011-12 college salary report published by payscale.com. According to the report, computer science graduates earn a starting median pay of $56,600, and by mid-career, it can go up to $97,900, depending on location, education, and experience**.

And what kinds of career can you pursue once you graduate from this program? Computer science

Follow these recommendations from the Human Resource professionals to ensure your interview experience is successful.

There are several key points to keep in mind even before you begin to prepare for the interview. Remind yourself that you would not have been scheduled for an interview if your qualifications and experience level did not meet the requirements for the position. Furthermore, not only is the interview an opportunity for the hiring manager to determine your fit with the existing team and company culture, but it is also an opportunity for you to assess whether this is a company and position that fits with your work style and career goals.

When preparing for an interview, one of the most important steps to take is to research the company by reading through all the pages on their website and keeping track of questions to pose at the appropriate time during the interview process. Check out the online reviews of the

What Is Cloud Computing In Layman Language?

Subhash was a smart, innovative and self-starter, 23 yrs old guy who started a small business with his limited budget. He always wanted to curtail the business expenses smartly and wanted to opt for smarter investment techniques. In the initial phase of his business he noticed he faced some really expensive and severe challenges. He enlisted the top challenges and one of them was buying hardware for each employee along with the software and their licenses which he discovered were extremely taxing. Moreover he detected other problems like storage capacity, keeping updates for newest software and ongoing trends in the market. He felt with every new hire more software were needed, such problems worsened the situation and distracted him from the goals of his business. He researched and finally chose Cloud computing- A smart and user friendly choice which is easy on pocket too.

In the earliest of days when Homo sapiens grew, they beautifully transformed themselves as humans from apes. Grew a little: understood basic needs- Food, clothing, shelter. Grew more- found mediums to fulfill those basic necessities. Then they started ‘Developing’, now they had farms for food, wells for water, mills for clothes,

What to Do If Your Computer Does Not Start

1. No Access to the Keyboard During the Boot Process?

Help, I can’t access my keyboard at boot!

If this is the case, I would recommend:

1-1. If using a USB keyboard, plug the keyboard into the primary USB ports on the back of the computer (on the motherboard). Restart the computer and try again.

1-2. Try another known working USB keyboard plugged into the primary USB ports on the back of the computer (on motherboard). Restart the computer and try again.

1-3. Try another known working PS/2 keyboard, restart the computer and try again.

1-4. If using a PS/2 Keyboard, try replacing your keyboard with a USB keyboard, restart the computer and try again.

1-5. If these steps fail, remove your keyboard connection and shut the computer off with the power button. While computer is off, plug the keyboard back into the computer and start the computer.

Still doesn’t work? Please go to “I need to flash my bios” section and proceed with flashing your bios.

How to Build a Computer and Component Selection

I get asked the same question very often, how to build a computer? It can be very deceiving to the average person’s eyes when they glance into an open computer. There are different “pieces” to be found and quite a few wires running around from one part to the next. All of this can be quite confusing and discouraging. The best advice I can give is that it looks more complicated that what it actually is. Don’t be afraid to do some trial and error to figure things out, within reason. Of course you have to be careful and not force components in spots they do not belong, but it is difficult to mix up as most things can only go one way, and will only fit in the correct location. Over the years it is how I learned most of what I do today, trial and error. One something goes wrong, there is always a way to fix it, and sometimes it just takes some patience and research to figure out a way to fix the problem.

I started building computers around 1996, when I was ten years old, and it became a hobby of mine

Why You Get Eyestrain and the Need for Computer Glasses

Computer eyestrain is the number one office-related health complaint in the U.S., with some 60 million Americans suffering from computer eyestrain according to the American Optometric Association. Computer use at work and home continues to grow exponentially. Computer use is associated with a number of visual and physical symptoms experienced by 50%-90% of all computer users. So, if you have experienced fatigue, headache, eye strain, blurred vision, dry or irritated eyes and neck or back aches at the computer it is possible that you are suffering just some of the symptoms called Computer Vision Syndrome (CVS). Solving the symptoms of CVS requires a visit to your eye doctor to determine if you need corrective lenses while working at the computer, especially if your computer use is two or more hours a day. The reason for computer vision related problems is further explained with a simplified description of how the eye and brain processes visual information.

Working at a computer is more visually demanding than doing other standard office work such as reading printed documents. Human vision is not designed for staring into a computer screen. Your eyes require constant sharp edged images like the characters found on

What Is Computer Speed Memory?

Increase Computer Speed Memory by Increasing the Ram (Memory)

Did you know that if you increase the memory on your computer, you can increase the speed? When you try to open a program on your computer, it needs to load itself from the hard drive into the memory. If the memory resources are low because there are too many programs open at the same time, or you have too many programs on your computer, this all takes memory to make things happen. The result will be a computer that runs very slow.

Nobody likes working with a computer that is slow. To have a computer that performs with speed, making the action process happen in 2-5 seconds, it is important to have ample RAM (memory) installed on your computer for computer speed memory. Many of the older computers might have 1 Gigabyte of memory if they are lucky, usually less. This is way too low by today’s standards. You should have a minimum of 5-6 Gigabytes of RAM and preferably 8-10 Gigabytes if you can afford it.

Each action performed, every program installed, takes up and uses computer memory. Don’t overload your computer. You can

Cloud Computing – Is It Safe?

There are essentially two kinds of computing environments:

On-premises computing is the traditional form of computing in which you or your company own and manage your own systems. All the applications you use, as well as your data files, are in your own computers on your own premises either on individual PCs or on an in-house local area network.

In cloud computing, by contrast, your applications and files are held remotely on the Internet (in cyberspace) in a network of servers which is operated by a third party. You access applications and work on your files from your PC simply by logging on to the network.

Cloud services are provided by cloud-hosting providers, companies such as Google, Amazon, Oracle Cloud, Rackspace, Microsoft Azure, and so on.

There is nothing fundamentally new about the concept of cloud services. If you are using Gmail, Hotmail or yahoo for your emails, you are using cloud services and probably have been for years.

What is relatively new is the types of services that are being offered in a cloud-environment. These now go far beyond email to cover all the IT services that an on-premises computing environment would deliver, such as

Are We Too Dependent on Computers?

A computer has been one of mankind’s greatest invention among other inventions ever since the foundation of science began. Its development was a result of years and years of long experiments spanning a hundred or so years conducted not just by one man, but many. Development of computers as it is today is a continuous process and it will ever be. Computers, however simple they may seem now to the computer literate, has a complex set of system underneath. It takes multiple disciplines in both computer studies and electronics to fully understand them. After all, computer in itself is subdivided into branches as is science itself.

While other technological inventions may have had already been developed prior to the foundation of science, “technology” is not yet a proper term for such. The word technology, after all, is always correlated with science and both science and technology are mutually inclusive to one another, strictly speaking in terminologies. Computers of today, however advanced they may seem, have had its origins in humble beginnings.

How did computer began?

Abacus, the earliest form of calculator, has been recorded to be in use since the early civilizations estimated to be

How to Keep Your Computer Cool

When your computer is on, nearly all of its components become hot. Constant exposure to high temperature can cause serious damage to your computer.

Here is a list of ways in keeping your PC cool.

Check if your fans are running.

This is the first step when you find your computer overheating. Open the case, and then check if all fans are still working. If at least one is not working anymore, consider doing repairs or getting a replacement.

Regularly clean your computer.

It is essential to regularly clean your computer, especially the cooling fans. The fans attached inside the computer case is used for active cooling of the computer. Over time, dust and dirt can accumulate in these fans. The accumulate dirt can slow down or, in worse, stop fans from working. If fans fail in expelling the hot air fast enough, some internal parts will eventually overheat.

To clean your cooling fan:

1. Shut down your PC.

2. Open the computer case.

3. If there is excessive dirt inside the computer case, take out the computer fan.

4. You can use compressed air, small electronic vacuum

Online Computer Repair and Remote Virus Removal

I have been doing remote computer repair for people across the United States and around the world for nearly a decade, giving PC help to people with malware removal, virus removal, pop ups, or a slow computer. Online computer repair or online virus removal is definitely a time saver and a money saver. Remote virus removal can certainly save a person hundreds of dollars over the cost of taking the PC to a local computer repair shop.

Although using a remote online computer technician is definitely the way to go for PC help, nevertheless there are some pitfalls. I constantly hear horror stories from customers that had previously used an online computer repair service for their computer problems with less than desirable results. Consequently I have put together this list of computer scams to watch out for when contracting with someone to provide remote computer help.

1. USA Based – Really? Most people don’t want to talk to someone in India with an accent so heavy that you can’t understand them. That’s why many websites will say, “USA Based.” But are they really? I have found that many websites advertise they are in the U.S. but the

Should I Fix My Computer or Buy a New One?

Unless you are a recent entrant to the world of computers, this is probably a question you’ve asked yourself before. After all, if your computer doesn’t work properly, you may have a strong instinct to throw it out and go get another one but keep wondering if it is worth fixing. This article is intended to help you decide which of these paths you should take to get a PC up and running so you can go about your work or play.

You may be thinking that since this is a computer repair technician writing this article, I’m going to tell you that in almost every case, you should fix your computer rather than get a new one. Not so. Just as there are a host of reasons to fix your computer, there are plenty of reasons to buy a new one instead.

Although the costs of consumer computers are nowhere near the costs of new cars, those of you who have had to decide whether to fix an older automobile or buy a new one may find it helpful to think about that process because it is similar. I would advise you to make two

Computing Crunch Power And The Simulation Hypothesis

It has been postulated that our reality might in fact be a virtual reality. That is, some unknown agency, “The Others”, have created a computer simulation and we ‘exist’ as part of that overall simulation. One objection to that scenario is that in order to exactly simulate our Cosmos (including ourselves) we would require a computer the size of our Cosmos with the sort of crunch power that could duplicate our Cosmos on a one-to-one basis, which is absurd. The flaw is that realistic simulations can be made without resorting to a one-on-one correlation.

WHY ARE WE A SIMULATION?

Here’s another thought on the Simulation Hypothesis which postulates that we ‘exist’ as a configuration of bits and bytes, not as quarks and electrons. We are virtual reality – simulated beings. Here is the “why” of things.

Really real worlds (which we presume ours to be) are simulating virtual reality worlds – lots and lots and lots of them – so the ratio of virtual reality worlds to really real worlds is lots, and lots and lots to one. That’s the main reason why we shouldn’t presume that ours is a really real world! If one

The History of Computers

While computers are now an important part of the lives of human beings, there was a time where computers did not exist. Knowing the history of computers and how much progression has been made can help you understand just how complicated and innovative the creation of computers really is.

Unlike most devices, the computer is one of the few inventions that does not have one specific inventor. Throughout the development of the computer, many people have added their creations to the list required to make a computer work. Some of the inventions have been different types of computers, and some of them were parts required to allow computers to be developed further.

The Beginning

Perhaps the most significant date in the history of computers is the year 1936. It was in this year that the first “computer” was developed. It was created by Konrad Zuse and dubbed the Z1 Computer. This computer stands as the first as it was the first system to be fully programmable. There were devices prior to this, but none had the computing power that sets it apart from other electronics.

It wasn’t until 1942 that any business saw profit

Breaking the Computer Buying Cycle

That New Computer Smell

If you are like most people when they go out and buy a new Personal Computer you probably get excited when you take it out of the box, turn it on and marvel at how fast it runs. When a computer is new it always seems to run faster and boot up quicker than your old computer. The applications and games seem to run without any slow down and when you get on the internet the pages load instantly on the screen, and you can quickly surf from one website to another. Overtime though, your computer can slow down and not run as quickly as it did when it was new.

This slow down can occur for a variety of reasons and when it happens it can be frustrating and spoil your computing experience. Often times when this happens it can be corrected by either cleaning up your hard drive, or running some diagnostics. Perhaps the computer has a virus and once you remove the virus, performance can be restored. What do you do though if you have done all those things and your computer is still running slow?

If your
