The Computers Changes

Nowadays, people can not live without computers and me neither! You won’t use a computer you bought 5 years ago! It is not because computers don’t last, just because they change so fast that you can not be satisfied with the performance of the computers you bought several years ago! For example, our family bought the first PC around 1988 when we thought the computer wewas so state-of-the-art and so expensive (it was expensive actually) we rarely used it before it was gone. Shortly after it went out of style, we had decided to throw it out, interestingly, that is when I turned out to be very interested in computers. Then I started to learn how to use this computer with its unbelievably slow processing speed. I learned very much from that experience since I could use it whatever way without being afraid of damaging it. Having discarded it, my mother bought a new Sony laptop; it is still on my desk now. I had used this laptop for 3 years and it has been not bad. I learned also a lot from the past 3 years of using this computer. It has only been used for downloading bit torrent files. Last week, I purchased a new laptop; it is brilliant except that its prices went down by $200 only one day after I got it. what are the chances!?Computers are one of those things that change so fast. No one could have imagined, in the 1970s that by the end of the 20th century, computers would be as present in people’s offices and homes as TVs? In the 1970s, computers were not really surprising, but only in huge business, government departments, and large organizations. These were what we call mainframe machines were truly large, they often took whole air-conditioned rooms, requiring professional technicians and run on exclusively-programmed software. Although we can still see these large machines somewhere, many of their functions have been replaced by small powerful personal computersIn 1975, a primitive machine called the Altair was launched in the USA. It can appropriately be described as the first ‘home computer’ and it gave us an idea of what the future PCs could be like. What is more, at the end of the 1970s, there was a machine called an Apple that followed the Altair. In the early 1980s, the computer giant, IBM produced the world’s first PC. This worked on an “operating system” called DOS, produced by a then small company entitled Microsoft. The IBM Personal Computer was widely copied. From those immature beginnings, we have seen the development of the user-friendly home computers and multimedia machines which are in common use today.Now computers can be small enough to hold in the hand, they are capable of providing information about traffic jams and directing where you are supposed to go, they can be used in hospitals to help doctors to diagnose diseases, they relieve office workers and accountants of boring, repetitive clerical work. Computers have become smaller and smaller, more and more powerful and cheaper and cheaper.Who is able to tell us what to expect in the next fifty years.
