Computer is so amazing with many functions. Four basic function if computer are input, processing, output and storage. Input collectively refers to all the resources used in creating a program. This usually consists of a programmer entering code into a computer with a keyboard.
Processing collectively refers to all of the internal functions the computer uses to control and make sense of information. The most basic components are a control unit, an arithmetic logic unit and random access memory for temporary storage. This represents a very simple model of a computer. Modern computers will add other processing components such as a multitasking operating system
Output is the display of information to the user. This can occur through the monitor, by way of audio through the speakers, or on paper via a printer. Output can also be written to a storage device like a CD-ROM or flash drive.

This component was not always present in the IPO model as it is not strictly necessary for a basic computer to function, but has been added as permanent physical memory has become a standard part of all modern computers.
Computer created base on living things. Computer also has a brain that control all functions and activities. Brian of computer called microprocessor. Microprocessor is an electronic device that can carry out complex calculations in the blink of an eye. Microprocessor also found in car, television and some many other electronic device. That mean computer
