Evolution Of Computer Technology

Today computers are an indispensable part of the lives of human beings but at one point of time there were no computers. Knowing the history of computers and how much progress has been made can aid us in understanding just how complicated the invention of the computer really is. Unlike other devices, the computer is the one invention that does not have any one specific inventor. Throughout the development of the computer, various people have made contributions to making a computer work. Some of these inventions were those of complete computers or other additions that helped revolutionize the computer that existed at that time. One such invention was the Integrated Circuit.

The single most important year in the history of computers is 1936. It was in 1936 that the very first computer was created by Konrad Zuse who called it the Z1 Computer. This was the first system that was fully programmable. Even though there had been devices that had come and gone before this but they didnt match upto it because of its superior computing power. Till 1942 no business saw profits and opportunities in computers. The first computer company was called ABC computers and was owned and operated by Clifford Berry and John Atanasoff. Two years later in 1942 came the Harvard Mark I computer which furthered the science of computing even more.

The age of computers saw its biggest change ever in 1953 with the introduction of International Business Machines known today as IBM. The company has always been a key player in the development of new systems. This was the first real competition to bee seen in the world of computing and helped to encourage faster development of better computers. The first contribution of IBM was the IBM 701 EDPM Computer. A year after this the first high level programming language was brought to the centre stage. This was a programming language that had not been written in ‘assembly’ or binary languages and was called FORTRAN which was written to enable more people to be able to program computers. In the year 1955 Bank of America, Stanford Research Institute and General Electric joined hands to introduce the very first computer for use in banks.

After that the evolution was quick. Computers like Apple I and II, The Scelbi, Mark-8 Altair, TRS-80, the Commodore Pet computers and IBM 5100 were the leaders of the sector of home computing. The micro processor was like the heart of the computer and began with the Intel 4004. from then it has evolved into todays Pentium IV, Dual core and Core 2 Duo processors. Along with the evolution in Hardware came the evolution in software which went from assembly languages to todays languages like C++, Java and PHP. There is more to come in this field and that more will surely be AI or Artificial Intelligence. The term was coined by John McCarthy and is today a major field of study.

Reasons Your Computer Chairs Break

Sadly, its not uncommon to have computer chairs snap under you. You might not even be that heavy, but chairs just arent made as well these days! Remember back when they were all metal? Those suckers withstood anything. These days, plastic is all youll find in most computer chairs. Overweight people tend to have even more problems since chairs often last only a few weeks before something breaks.

While you can keep using the chair without an arm or even if the back cracks and ends up at a weird angle (yes, this happens to many of us!), once the support column or one of the wheels or base legs goes, youre pretty much hooped. Many people cobble together Frankenchairs, made from a base that still functions with a seat that is still intact, just to save a bit of money. It might seem silly, but if you have computer chairs break on you every couple of months, this is what happens.

So, why do your chairs break? Here are three main reasons:

1. Its not built for weight. Most computer chairs are designed to withstand 150-200 lbs. So, if you weigh anything over that, your chair isnt going to last very long. Thats why you might want to look at computer chairs for overweight people, which can be rated for up to 500 lbs.

2. The material is poorly made. Unfortunately, there arent many high standards in the world of office chairs. Overweight people have discovered that plastic simply isnt designed to withstand much weight . . . it twists and bends and eventually cracks under the stress. These chairs are often stamped out of low cost plastic, which is not sturdy enough.

3. You move too much. When a computer chair is working properly, it will roll smoothly over the floor. However, poorly built chairs cant hold up to the weight. They will sink down, essentially crushing the wheels against the caps and the wheels wont roll. When this happens, you will end up jerking the chair to move it and that puts extra stress on the already fragile joints.

Often its a combination of these three factors that causes a computer chair to give way. You will want to make sure that you choose your chair very carefully. There are a number of designs in computer chairs for overweight people that will hold more and resist more action. Even if you arent obese, choosing a sturdier chair can be a good investment in the long run.
