The first generation Computers : 

The first generation Computers The First generation computers used vacuum tubes. They were so huge that they can also take an entire room. It was very expensive and it provided us a load of loss when we wanted to operate it. This was because it consumed a lot of electricity, and got overheated very frequently. this lead to the risk of getting it malfunctioned. Ctnd. Next Page

Slide 22: 

It also used a magnetic coated iron –oxide drum for storing. It contained tracks on which computer stored it files. It contained up to 200 tracks and the drum rotated at a speed of 3,000 rpm. Eniac : (ELECTRONIC NUMERICAL INTEGER AND COMPUTER), IS AN EXAMPLE OF THE 1ST GENERATION COMPUTER. IT WAS DEVELOPED BY THE MILITARY ORDNANCE TO COMPUTE ON WORLD WAR II BALLISTIC FIRING TABLES. IT WEIGHED 30 TONS, AND CONSUMED 200 KILOWATTS OF ELECTRICITY TO WORK. IT CONTAINED 18,000 OF VACUUM TUBES, 1,500 RELAYS, AND HUNDRED 1,000 OF RESISTORS, CAPASITORS, AND INDUCTORS.

Second Generation Computers : 

Second Generation Computers Second Generation of Computers consisted transistors and replaced vacuum tubes in the market. Transistors are composed of a semiconductor material that amplifies signals or connect or disconnect a circuit. The input of the second generation computers was punched cards and the output was the printouts. Ctnd. Next Page

Slide 24: 

Transistors allowed computers to become smaller, faster, cheaper, more energy – efficient and more reliable than the first generation computers.

Third Generation computers : 

Third Generation computers The invention of the integrated circuits lead to the development of the first generation computers. The transistors were miniaturized and were putted in semiconductors that drastically increased the speed as well as the efficiency of the computers. Silicon is a non – metallic material that is the best substance to mace microprocessors (chips) and transistors of computers.

Fourth Generation Computers : 

Fourth Generation Computers The Microprocessor made the 4th Generation Computer to come into being. It controls of the logic of all the digits. Even it is present in atomic clocks and fuel injection system in cars. “Intel” “ is the most famous company to mace microprocessors
