1. Computer hardware is an electronic circuit made up of small metal parts. It is made of panels and has different functions depending on the type of hardware. Each has Main Board, Power Supply, RAM, CPU, HDD… ..
2- A system Unit is a container that stores and assembles hardware components. Many other: CPU, RAM, HDD and other devices That makes the computer system work.
3- Motherboard is one of the largest circuit boards contained in the Computer Case. Which is responsible for connecting to other hardware devices such as Power Supply, CPU, RAM, HDD, FDD, Sound, And other devices that make the computer work.
4- CPU is the most special memory for computers or we can say that It is the computer brain that is responsible for calculating, controlling, Translate all construction and operation of all computer functions. CPU names and types are Pentium, Duron, Celeron, Xeon, Athlon… ..
5- Input Device is a device that receives data from users, such as mouse clicks. Or a computer keyboard. For example Keyboard, Mouse, Light pen, Scanner, Joystick, Touch Screen, Barcode reader, Microphone. - Output Device is a device that receives electronic signals from the computer. system and it converts into a result that the user can see. Example: Monitor, LCD Projector, Speaker, Printer.
6- A computer system is a set of devices that can receive and store software and Data solved by those applications by the implementation integrated into Its instruction to Data and Result.
7. The function of the Storage Device is to store files and the structure of the program for the need to process. There are two types of storage devices: - Primary Storage Device is Mian memory that works directly with the CPU, such as RAM, ROM, and so on. - Secondary Storage Device is the Main Device that has the function of storing data such as:
Hard Disk And so on. Computer software is a set of structures or programs that can tell the computer hardware. What to do to make hardware useful We need software to make Supervise the operation of the computer system.
9. The term information technology refers to the creation, receipt, processing, storage, And information sharing by the electronic wife. For example, radio, television, telephone Computer...
