1 microcomputre-is at the lowest end of the computer range in term of speed and strong capacity.
2 .Mini computer-this is desinrd to support more than one user at a time.
3 . mainframe -the types of computer are genetally 32-bit microprocrssor they operate at very hight speed.
4.supercomputer-they are the fastest and most expensive machines
extremelcomputers of 1990s are said to be fifth genetayion computers the speed is y high in fifth generTheation computer apart from this it can perform parallel processing.
ENIAC-It was the first electronic built in 1946 at university of pennsylvania USA by john Eckert and Mauchy It was namesd Electronic Numerical integrator and calcicatoe (ENIAC) was 30(50feet long weighed 30 tons contained 18,000vacuum trbes 70,000registers 10,000capacitors and required 150,000watts of electricity Tody your facoritre computer is many times as powerful as ENIC still size is very small.
