Conclusion

As a conclusion , the computer system , especially the input and output devices

had helped people to do their work more efficiently.

what is output and output devices?

Meaning of output: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 sounds.

Meaning of output devices:Any hardware component that present information (processed data) one or more people..
Example of output devices:-

Monitor - A monitor is the screen on which words, numbers, and graphics can be seem. The monitor is the most common output device.
Compact Disk - Some compact disks can be used to put information on. This is called burning information to a CD. NOTE: A CD can also be an input device.
Printer - A printer prints whatever is on the monitor onto paper. Printers can print words, numbers, or pictures.
Speaker - A speaker gives you sound output from your computer. Some speakers are built into the computer and some are separate.
Disk Drives - A disk drive is used to record information from the computer onto a floppy disk or CD.

Headphones - Headphones give sound output from the computer. They are similar to speakers, except they are worn on the ears so only one person can hear the output at a time.

what is storage and storage devices?

Computer data storage:storage is in location in which data,instructions and information are saved for future use.
Storage devices:A storage device 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:Sequence of interdependent and linked procedures which, at every stage, consume one or more resources (employee time, energy, machines, money) to convert inputs (data,material, parts, etc.) into outputs. These outputs then serve as inputs for the next stage.

Processor: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?

Meaning of input:Any data and instructions entered into the memory of a computer.there are four types of input which are text, graphics , audio and video.

scanner

Input devices:Any hardware component that allows users to enter data and instructions into a computer.e.g. keyboard, mouse, scanner, barcode reader, mouse touch screen and graphic tablet

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.
A computer system is refer to the hardware and software that run a computer or computers.
