History of Computers

The history of computers went all the way back to 1940.When the computer was made.this is what it looked like.

What is CPU?

Alternatively referred to as the brain of the computer, processor, central processor, The computer CPU is responsible for handling all the instructions it receives from hardware and software running on the computer.

The processor is has generally replaced the term central processing unit. The processor in a personal computer or embedded in small devices is often called a microprocessor.
The Processor and the Main Memory

Alan Turning

Alan was born in 1912.He committed suicide in 1954.He is a mathematician and logician and his artificial intelligence.Alan helped Britain solve some of the enigma codes.Alan turning would have been 103 this year.They even made a film about his amazing machine.

Today, all monitors are created using flat panel technology;rather than a big heavy computer.Instead with flat panel technology,the compute is a lot lighter and smaller.

First Generation (1940-1956) Vacuum Tubes

The first computers used vacuum tubes for circuitry and magnetic drums for memory and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions.

First generation computers relied on machine language the lowest-level programming language understood by computers, to perform operations, and they could only solve one problem at a time. Input was based on punched cards and paper tape, and output was displayed on printouts.

Second Generation (1956-1963) Transistors

transitors replaced vacuum tubes and ushered in the second generation of computers. The transistor was invented in 1947 but did not see widespread use in computers until the late 1950s. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessors

Third Generation (1964-1971) Integrated Circuits

The development of the integrated circuits was the hallmark of the third generation of computers. Transistors were miniaturized and placed on silicon chips, called semiconductors, which drastically increased the speed and efficiency of computers

Fourth Generation (1971-Present) Microprocessors

The microprocessors brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip. What in the first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer from the central processing unit and memory to input/output controls on a single chip.

Tim Bernes Lee

He is the inventor of the internet and he was only 34 when he created the internet.He was also knighted.He died when he was only 59 years old.
