HISTORY OF COMPUTER

In our modern generation many gadgets are improving like computer.

But did we know how it start?

Base on my opinion, it started in very low but see now it's very progressive.

And I believe it will improve more...

''Anyway let's discuss it''

Brief History of Computers

A Look Back at Computing

Computers have become one of the most important parts of modern society. Nearly everything that is modern required or uses computer related technology in some way. But how did computers as we know them come to exist? Did someone sitting in his lab just one day say, "Aha! I've got it! The computer!"? Well, no, that is not how this happened. Rather, many years of brilliant ideas and research from many different individuals contributed to modern computing. The field is constantly evolving at a pace unlike anything before it as techniques are polished and new breakthroughs are made.

 

First Generation (1950 - 1957)

 

    The first computer to implement Von Neumann's idea was the EDVAC in 1951, developed in a project led by Von Neumann himself. At the same time a computer using stored programs was developed in England, called the EDSAC. [25] The EDVAC was commercialized and called the UNIVAC 1. It was sold to the U.S. Bureau of the Census in March, 1951. This was actually the first computer ever built for sale. [26] The UNIVAC 1 made a famous appearance on CBS in November, 1952 during the presidential election.

Second Generation (1957 - 1965)

The second generation of computing took place between 1957 and 1965. Computers were now implementing transistors, which had been invented in 1947 by a group of reseachers at Bell Laboratories, instead of vacuum tubes. [30] Because of the transistor and advances in electrical engineering, computers were now cheaper, faster, more reliable, and cheaper than ever before. More universities, businesses, and government agencies could actually afford computers now.

Third Generation (1965 - 1975)

he third generation of computing spanned from 1965 to 1975. During this time integrated circuits with transistors, resistors, and capacitors were etched onto a piece of silicon. This reduced the price and size of computers, adding to a general trend in the computer industry of miniaturization. In 1960 the Digital Equipment Corporation introduced the Programmed Data Processor- 1 (PDP-1), which can be called the first minicomputer due to its relatively small size. [34] It is classified as a third generation computer because of the way it was built, even though it was made before 1965. The PDP-1 was also the computer that ran the very first video game, called Spacewar (written in 1962).

Fourth Generation (1975 - 1985)

  The fourth generation of computing spanned from 1975 to 1985. Computer technology had advanced so rapidly that computers could fit in something the size of a typewriter. These were called microcomputers, the first one being the Altair 8800. The Altair 8800 debuted in 1975 as a mail-order hobby kit. Many people acknowledge the Altair 8800 as the computer that sparked the modern computer revolution, especially since Bill Gates and Paul Allen founded Microsoft with a programming language called Altair BASIC-- made specifically for the 8800. [36] Now that computers could fit on desks they became much more common

Fifth Generation (1985 - Present)

   The changes that have occurred since 1985 are plentiful. Computers have gotten tinier, more reliable, and many times faster. Computers are mostly built using components from many different corporations. For this reason, it is easier to focus on specific component advancements. Intel and AMD are the main computer processor companies in the world today and are constant rivals. [42] There are many different personal computer companies that usually sell their hardware with a Microsoft Windows operating system preinstalled. Apple has a wide line of hardware and software as well.
