Important Computer parts and storage devices

Hardware refers to all the parts of any computer that appear as tangible objects. This includes circuits, displays, power supplies, cables, keyboards, printers and mouse.


The hardware

Hardware refers to all the parts of any computer that appear as tangible objects. This includes circuits, displays, power supplies, cables, keyboards, printers and mouse.

Mother-board: It is the main circuit board (circuit) of any mother-board. It is also known as main-board or system board.

CPU (Central Processing Unit): It is the central electronic chip that determines the processing capability of a computer.

Memory: It is that part of the computer that temporarily stores information about actions, documents and stem operations.

Bus: It is an electronic line (electrical circuit) that helps 1 and 0 move from one place to another.

Expanse slots: They appear on the motherboard. These are sockets in which adapters are placed.

Ports and connectors: A port is a connection device (connector) that is mounted on a motherboard or separate adapter.

Bay: Bay is the place inside the computer compartment where hard drives, floppy drives, or CD-ROM drives are located.

Power Supply: Power supply generally makes the domestic electrical system computer usable.

Sound components: The sound card allows the computer to record and play high quality sound.

Computer system
A computer working for a general-purpose is divided into four parts:

Economic and Logic Unit (ALU),
Control unit,
Memory and
Input and output devices (jointly called I / O)

All these parts are connected to each other by a group of wires by bus.

(A) Arithmetic Logic Unit (ALU)
ALU can perform operations in two types of classes: econometric and logic.
The kind of arithmetic operations that ALU supports can be limited to addition or subtraction or even multiplication and division, in addition to trigonometric functions (sine, cos, etc.). Can go. Square root is also possible.
The verbs of logic include Boolean logic: end, or, gjor, and not. It can also process Boolean logic with the creation of complex stipulated statements.

(B) Control Unit
The control unit (sometimes called a control system or a central controller) directs various parts of the computer. It reads and annotates (de-codes) a program one by one. The control system de-codes each instruction and converts it into a series of control signals that implement other parts of the computer.

(C) memory
The memory nerves (cells) of a computer can be viewed as a list in which digits can be placed or read. Each cell has an inscribed address and can preserve a number. The computer can be instructed to put the number 123 in cell number 1357 or add this number to the number present in cell number 1357 and add it to the number in cell number 2468 and put the answer in cell number 1595. Information in memory can be practically anything. Letters, numbers and even instructions given to the computer can be easily stored in memory. It depends on the software
Does what he values, because memory sees nothing, just a series of numbers.
The main memory of a computer is found in two main classes: random access memory (RAM) and read only memory (ROM). The RAM can be read or written at any time on the CPU's instructions, but the ROM is already loaded with software or data that can never be changed, so the CPU can only read it. The ROM is commonly used for early computer start-up instructions.

Important Input and output devices

hard disk
Input
The input hardware allows you to insert data into your computer.
Give convenience. Primary equipment used in it
Key board and mouse.

Key-board: The key-board sounds like a typewriter. To the right of the keyboard is a keypad showing numbers. This sequence of numbers is similar to a 10-digit calculator, which helps the operator sort data quickly.

Mouse: It is a device that helps you to conduct the activities on the screen (screen) as you like.

Processing: The central processing unit or CPU is the brain of your computer. It replaces the electrical circuits (electronic circuits) that allow the computer to follow instructions from the ROM or create a program in RAM.

Output
Output devices such as monitors and printers tell you that input is available for your viewing and use.

Computer storage device
A variety of computer storage equipment is available in the market. The information on the available storage devices helps you make maximum use of your computer hard drive. Also, it helps your computer to crash and run at maximum speed.
