Computer is a programmable machine that carries out what it has been instructed to do. Conventionally, there are a few basic operations that can be performed by a computer which is input, processing, output and storage.

Evolution of computer :

1)    First Generation (Vacuum Tube) (ENIAC, UNIVAC)
2)    Second Generation (Transistor) (IBM 1401)
3)    Third Generation (Integrated Circuit)
4)    Fourth Generation (VLSI/ULSI)
5)    Fifth Generation (Artificial Intelligence)



There are seven categories of computer which are embedded computers, mobile computers, personal computers, midrange, mainframe computers, supercomputers and ....

Data & Information

Information Processing




Computer system use I-P-O Method to process data. This method consists of input, process and output. Input is any data insert in the computer, output is the data that has been process into a useful form whereas processing of data exist in CPU.

Information management (IM) is the collection and management of information from one or more sources and the distribution of that information to one or more audiences. IM is needed in order to managed the data and information consist in any companies, organization and institution.
