The input unit takes the input, the central processing unit does the processing of data and the output unit produces the output. The memory unit holds the data and instructions during the processing.

The functional components of a computer performs. Every task given to a computer follows an Input- Process- Output Cycle (IPO cycle).

A discipline that applies engineering principles of design and analysis to biological systems and biomedical technologies.

These printers do not use striking mechanism for printing. They use electrostatic and laser technology. Quality and speed of these printers is better than Impact printers. For example, Laser printers and Inkjet printers are non-impact printers.

The scanner converts any type of printed or written information including photographs into digital pulses, which can be manipulated by the computer.

CPU is the major component which interprets and executes software instructions. It also controls the operation of all other components such as memory unit, input and output units.

IBM 360 Series, Honeywell 6000 series.

Input Unit	Output Unit
An input device feeds information to a computer system for processing.	output device reproduces or displays the results of that processing.
Input devices only allow for input of data to a computer.	output devices only receive the output of data from another device.
It is a peripheral device used to provide data and control signals to an information processing system such as computer.	It is a unit which sends data from the computer to another device.
Eg. keyboard, mouse	Eg. printer, monitor

The ALU is a part of CPU where various computing functions are performed on data. ALU performs arithmetic operations such as addition, subtraction, multiplication, division and logical operations.

Data Information Data is a collection of facts from which the information may be derived. It is an unprocessed collection of facts in a manner suitable for communication, interpretation or processing. Information is a collection of facts from the conclusions can be drawn. Information is a processed facts, active, Business based and transformed from data. Eg. 134, 16, Kavitha Does not give meaning. Eg. Kavitha is 16 years old.
