WHAT IS COMPUTER SYSTEM?
A computer system is defined as combination of components designed to process data and store files. A computer systems consists of four major hardware components. For example input devices, output devices, processor and storage devices. A computer system requires hardware, software and a user to fully function.
WHAT IS INPUT AND INPUT DEVICES?
Input:
The act of entering data into a computer.Whatever goes into the computer. Input can take a variety of forms, from commands you enter from the keyboard to data from another computer or device. A device that feeds data into a computer, such as a keyboard or mouse, is called an input devices.
Input Devices:
An input device is any hardware component that allows you to enter data, programs, commands, and user responses into a computer. Input devices include the keyboard, pointing devices, scanners and reading devices, digital cameras, audio and video input devices for physically challenged user. Each of these input devices is discussed in the following pages.
Example:
WHAT IS PROCESS AND PROCESSOR DEVICES?
Process:
A process is a program that is running on your computer. This can be anything from a small background task, such as a spell-checker or system events handler to a full-blown application like Internet Explorer or Microsoft Word. All processes are composed of one or more threads.
Processor Devices:
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.
Example:
WHAT IS STORAGE AND STORAGE DEVICES?
Storage:
In a computer, storage is the place where data is held in an electromagnetic or optical form for access by a computer processor. Storage is frequently used to mean the devices and data connected to the computer through input/output operations - that is, hard disk and tape systems and other forms of storage that don't include computer memory and other in-computer storage. For the enterprise, the options for this kind of storage are of much greater variety and expense than that related to memory. In a more formal usage, storage has been divided into: primary storage, which holds data in memory (sometimes called random access memory or RAM
and other "built-in" devices such as the processor's L1 cache, and secondary storage, which holds data on hard disks, tapes, and other devices requiring input/output operations.
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.
Example:
WHAT IS OUTPUT AND OUTPUT DEVICES?
Output:
Anything that comes out of a computer. Output can be meaningful information or gibberish, and it can appear in a variety of forms -- as binary numbers, as characters, as pictures, and as printed pages. Output devices include display screens, loudspeakers, and printers.
For example, display screens output images, printers output print, and loudspeakers output sounds.
Output Devices:
Output devices are pieces of computer hardware that allow a computer system to communicate information to a user or another system. This information can be in any form, and includes sound, images, and even tactile experiences. Output devices can usually only be used to send data from the computer; items called input devices allow users and other systems to send data to the computer.

From the task given, I have learned much about computer system and gained some blog building experience. I hope this blog can help people to increase their knowledge in ICT .
