Computer information ppt

Computers transform data into information.
Data is the raw material; information is processed data.
Data is the input to the processing; information is the output.
A useful model to describe the relationship between data and information is called the systems model.
It shows that data goes into a process and information is then output.

Computers consist of hardware, the physical parts of the computer and software, the programs that tell the computer 'what to do.' Processing data into information (the computing process) involves more elements than just hardware and software.
All these elements must be organized so that each works smoothly and effi ciently with the others.

A computer is an electronic device, operatingunder the control of instructions (software)stored in its own memory unit, that can acceptdata (input), manipulate data (process), andproduce information (output) from theprocessing.
Generally, the term is used todescribe a collection of devices that functiontogether as a system. 2 3.
