what is output and output devices?

Output is data that has been processed into a useful form,called information to give out. For example, display screens output images, printers output print, and loudspeakers output sound.
An output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system to the outside world such as:

monitor

speakers

printer

what is storage and storage device?

Computer data storage is in location in which data, instructions and information are saved for future use.

Storage devices is a hardware device capable of storing information. There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard disk drive.

what is process and processor?

Process is a sequence of interdependent and linked procedures which, at every stage, consume one or more resources (employee time, energy, machines, money) to convert inputs into outputs. These outputs then serve as inputs for the next stage. 
A processor is the logic circuitry that responds to and processes the basic instructions that drive a computer.The term processor has generally replaced the term central processing unit (CPU). The processor in a personal computer or embedded in small devices is often called a microprocessor.

what is input and input devices?


Input is an item external to a system (such as process) that is transformed by the system (usually together with one or more other items) to become an output. Input devices are any machine that feeds data into computer such as :


joystick

 

mouse

scanner



             



keyboard





what is computer system?

A system of interconnected computers that share a central storage system and various peripheral devices such as a printers, scanners, or routers. Each computer connected to the system can operate independently, but has the ability to communicate with other external devices and computers.
