Objective
This blog was created as a task assigned by the teacher to student ICT. Besides that, I would like to share with other students in other related subjects ICT. I hope with the blog, we will be able to increase knowledge of ICT subjects.

What is computer system?
A system of interconnected computers that share a central storage system and various pheriperal 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.
What is input or input device?
INPUT :
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 :
Any machine that feeds data into a computer. For example, a keyboard is an input device, whereas a display monitor is an output devices. Input devices other than the keyboard are sometimes called alternate input devices. mice, trackballs, and light pens are all alternate input devices.
Example of input devices :
What is process and processor?
PROCESS :
In computing, a process is an instance of a computer program that is being executed. It contains the program code and its current activity. Depending on the operating system (OS), a process may be made up of multiple threads of execution that execute instructions concurrently.
PROCESSOR :
The processor (CPU, for Central Processing Unit) is the computer’s brain. It allows the processing of numeric data, meaning information entered in binary form, and the execution of instructions stored in memory.

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. There are two general usages.
STORAGE DEVICES :
A data storage device is a device for recording (storing) information (data). recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.

What is output and output devices ?
OUTPUT :
Output is the term denoting either an exit or changes which exit a system and which activate/modify a process. It is an abstract concept, used in the modeling, system design and system exploitation.
OUTPUT DEVICES :
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 (such as a computer) to the outside world.
