The development of electronic computers can be divided into five generations depending upon the technologies used. The following are the five generations of computers. First Generation of Computers (1942-1955) Image Courtesy: www.computerhistory.org. The beginning of commercial computer age is from UNIVAC (Universal Automatic Computer). Jul 12, 2018 1. First Generation Computers (1942 to 1954) – Based on Vacuum Tubes. The first generation computers were used vaccum tubes as the main electronic part. For memory devices punch card and paper tapes were used. Magnetic drums are also used for storage.At that time memory was very expensive. First Generation of mordern computer (1946 - 1954) The period of first generation was 1946 - 1954. Computers of first generation used vacuum tubes as the basic components for memory and circuitry for Central Processing Unit.The first electronic computer, ENIAC (Electronic Numerical Integrator and calculator) was developed in 1947 at the University of Pennsylvania, USA. First Generation The period of first generation: 1946-1959. Vacuum tube based. The first generation computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. The vacuum tube was developed by Lee DeForest. Computer - First Generation - The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU.

Computer - First Generation - The period of first generation was from 1946-1959. The computers of first generation used vacuum tubes as the basic components for memory and circuitry for CPU. Generation in computer terminology is a change in technology a computer is/was being used. Initially, the generation term was used to distinguish between varying hardware technologies. Nowadays, generation includes both hardware and software, which together make up an entire computer system. There are five computer generations known till date.

Second Generation Computer

There are five computer generations known till date. Each generation has been discussed in detail along with their time period and characteristics. In the following table, approximate dates against each generation has been mentioned, which are normally accepted.

Following are the main five generations of computers.
