About the computer ............
Peace, mercy and blessings of God and
Theme for computer
I wanted to ask you a story about lessons Alkmbputr and I will try to continue the lessons to the end you have collected your information from books and some sites of Arab and foreign and tried to summarize for you, and chose the important points in the computer and hope of all the brothers and sisters that they found no wrong typographical or technical or any mistake was that good for us or if you criticize any information I hope to join us, and the piece can be helpful and benefit ...
Definition of computer:
The computer is an electronic machine used to process the input data for the device, by the CPU to get useful information, and is done by programs that are known to the computer.
Computer Science
Computer science is divided into two main pillars:
Hardware Equipment Division
Department of Software Programs
First: Equipment Division (Hardware):
Equipment is tangible components of the computer and that can be touched by hand the electronic components, electrical or mechanical. Such as a mouse keyboard screen microphone headsets ... etc. (God willing we will address it in detail Upcoming classes).
Will Nksmha into four sections
Input Devices (Input):
Used in data entry and information in various forms to the computer, and a Basic Input (Standard Input) is the keyboard (Keyboard) and is used to enter commands, text, and there are devices other input used to introduce other forms of data such as scanner Scanner for the introduction of images, a microphone input sounds and music , Mouse mouse to enter commands by clicking or drag and drop (Drag & Drop),
Processing devices (Processing):
Treatment device main central processing unit (CPU) is a shortcut to a (Central Processing Unit) is the central processing unit as a reason for humans where most of the operations of basic computer such as controlling traffic and determine the memory addresses that must be read from or write and to determine which units or data takes precedence in execution and other operations.Divided into the central processing unit into two main sections, namely:
Control unit (CU) ControlUnit: It is responsible for controlling all devices and computer data.
The unit of account and logic (ALU) Arithmetic & Logic Unit: which is responsible for the performance and implementation of all calculations and logical within the computer.
* Note:
(Calculations are the plus (+) and minus (-) and division (/) and multiplication (*)).
(Are the Boolean operations} <,>, = <, =>, =, NOT, OR, AND, XOR {
Storage devices (Storage Device):
This is where the data storage and information permanently or temporarily divided into two parts:
A. Internal storage: data is stored within the computer itself is divided into two parts:
1. Permanent internal storage: it is either stored in the hard drive the image HardDisk electromagnetic or permanent memory in the ROM image on the electrical pulses.
2. Temporary internal storage: is in the cache memory of RAM, where the computer scans all the contents of the RAM as soon as electricity was cut off from the device, where it should be the RAM is completely empty when you start your computer.
B. External storage: This is to save the data on floppy disks, Floppy or CDROM discs or tapes Tape or hard disk, Zip Drive, hard disk drive to save outside of your computer Hard Disk.
Organs output (Output Device):
Used to output data from the computer to the user in various forms of data.
Output devices are: the screen is called a base I StandardOutput used to output data to a visual image, the speakers used to output the audio data in the form of audio, the printer used to output data on paper, through which printing research, books, envelopes, envelopes, cards, and many types of securities in different forms.
