They are biggest in size. they are fastest,powerful and most expensive computer. They are used to processes like weather forecasting, aircraft designing, defence related work which require a lot of data to be processed
3
IBM's ASCI white
4
they are large and expensive, they have powerful processors and very large memories. they are used in large banks airlines and universities
5
IBMz14
6
they are small and cheap, They have less processing power and can process large amount of data. used in medium or large sized businesses colleges banks and libraries
7
IBM's AS /400 and Hp's HP3000
8
they are smaller and cheaper and used in small businesses schools and at homes. They ate used by single user and microcomputers come in different shapes

in 1944 Howard H.Aiken
24
it was the first fully digital computer consist of 20,000 vacuum tubes 30 meters long and 2.4 meters high and weighd more than 27 ton it was originally build to help army
25
In 1945 by John presper eckert and john muckly
26
it was the first electronic copmuter that was used to store programs
27
It was the first commercialy available electronic computer
28
its invented by Proffesor M.Wilkes in Cambridge univesritie,England in 1949 and consist of 600 Kg and occupied an area of 20 square meters.

invented by J.P.Eckert and J.W.Muckly in 1951 and consist of 13,000 Kg and occupied an area of 35.5 square meters
31
1. Their operating speed were quite slow 2. Their Power consupttion was very high 3. They required a large space for installation
32
1. They used transistors 2. They were smaller faster cheaper and more effecient than 1st gen 3. Programming languages like COBOL, GW BASIC and FORTRAN come into use in this period
33
The IBM 1401 and RCA501 are examples
34
1. They used ICs 2. They were smaller than 2nd gen
