Today we can discus about generations of computers
1st Generation Computers
UNIVAC (Universal Automatic Computer) produced in the late 50s was the first computers like ENIAC (Electronic Numerical Integrator and calculator) EDVAC (Electronic Discrete Variable Automatic Computer)
The ENIAC was an electronic vsersion of Mark I. Mechanical relays were replaced by electronic componets and were much faster than Mark I. The use of binary system and the internal storage of instruction written in digital form were the features of EDVAC. EDVAC was the first stored program electronic computer. But due to the delay in procuction, EDSAC which was built at University of Manchester in England is considered as the first stored programme electronic computer. It was in 1942.
In 1953, IBM, entered into the computer market by introducing IBM 701. By the time of IBM 650, IBM dominated the Mark by two third of it.
These are the first generation computers with vaccum tubes and stored program concept.
IInd Generation Computer (1960-64)
Introduction of the transistors (Solid State ciculatory) in place of vaccum tubes and the usage of magnitic core storage were responsible for the birth IInd generation computers
Transistor, which performs same function of a vaccum tube is similar in size, less experience generates almost no heat and also consumes only less power.
The second generatiohn computers were smaller, faster and reliable than that of first generation. They needed only little or some times no air conditioning.
The second generation also was dominated by the IBM. The most popular among them were IBM1401 (for small or medium lever business reqyurenebts) IBM 1620 (small scientific application) IBM 7000-7094 (large scale computation)
IIIrd Generation of computers (1965-70)
The evolution of IIIrd generation computers started when IBM 1360 was released on the market in 1965.
Integrated solic-state devises (ICs) improved secondary storage devises. new 1/0 devises (visual disply units, magnetic ink readers high speed printers) marked the birth of IIIrd generation computers.
