On the third generation computers, included the development of an operating system, which allowed machines to run many different programs at once with a central program that coordinated the computer’s memory.

By the fourth generation in 1971, the only objective was to reduce the size. In 1980 large scale integration squeezed hundreds of thousands of components onto a chip; this also increased their power, efficiency and reliability. AS computers became more widespread in the workplace, their potential was more developed. Small computers became more powerful that they could be linked together, share memory space, software and information.

After many inventions and developments, computer programs of modern computers on which

After many research and development, a joint venture between the United States government and the University of Pennsylvania made a computer that consisted of 18000 vacuum tubes, 70000 resistors and 5 million soldered joints, the computer was such a massive piece of machinery that consumed 160 kilowatts of electrical power. In the mid-1940’s john von Neumann designed the electronic discrete variable automatic computer with a memory that holds both a stored program as well data. The stored memory technique as well as the conditional control transfer allowed the computer to be stopped and then resumed, allowed greater versatility in computer programming. Von Neumann’s key element was the central processing unit which allowed all computer functions to be coordinated through a single source.

In 1948 the invention of the transitor made a great change in computers development; it replaced the large vacuums tubes in televisions, radios, computers and as a result the size of electronic machinery has been shrinking ever since. Transitors as the second generation computers led into smaller, faster, more reliable and more energy efficient than their predecessors.

There was an improvement in transitors over the vacuum tubes. The IC combined
