Super Computer are the most powerful computers made,
and physically they are some of the largest. These system
can process huge amounts of data, and the fastest
supercomputer can perform more than one trillion
calculation per second.

A Complete computer system consists of mainly four parts:
1.Hardware ( The Computer0
2.Software ( Program)
3.Data ( Information )
4.User (People )

Hardware The computer’s hardware consists of interconnected electronic devices that you can use to control
the computer’s operation , input and output
Software tell the computer what to do. Here the program refers to any piece of software
Data A computer primary job is to process these tiny pieces of data in various ways, converting them into useful
information
User People are the computer operators, also known as users. One can argue that some computer system are
complete without a person’s involvement however no computer is totally autonomous.
