Components of Computer

Components are made up of two parts: hardware and software. The physical equipment required to create, use, manipulate, and store electronic data is referred to as hardware.

The computerized instructions that operate a computer manipulate the data and execute particular functions or task is referred to as a software.

All Computers require the following hardware components:

Central Processing Unit (CPU): This is known as the brain of the computer. This is a simple chip located at the heart of the computer that enables it to process data also called a processor.
Memory: This is an area within a computer system that holds the data waiting to be processed.
Storage Device: This is the place where a computer puts the data for future use.
Input device: The devices that allow data and instructions to be entered into the computer (Such as keyboard, mouse, etc.)
Output Device: The devices that allow information to be represented to the user such as display screen, printer, etc.

Most Commonly Used Computer Software

  • Browsers- Google Chrome, Mozilla Firefox, Microsoft Edge, Opera Mini, Apple Safari, etc.
  • Media Player- VLC Media Player, Window Media Player.
  • Microsoft Office- Word, Excel, PowerPoint, etc.
  • Editing Software- Adobe Photoshop, Premiere Pro, Final Cut Pro, etc.
  • Operating System- Microsoft Windows, Google Android, IOS, Mac OS, Linux.

Full Form of Computer Related Parts

Full-Form of CPU
C- Central
P- Processing
U- Unit

The Part of the computer that executes program instructions is known as the processor or Central processing unit (CPU).

The Speed of the CPU chip is measured in GigaHertz (GHz) or Billions of cycles per second. The speed of a computer mainly depends on the speed of the Processor.

CPU consists of two parts:
A- Arithmetic Logic
L- Logic
U- Unit

ALU performs two types of operations – Arithmetic and Logical. Arithmetic operations include addition, subtraction, multiplication, and division.

Logical Operations consist of comparing one data item to another to determine if the first data is greater than, equal to, or less than the others.

C- Control
U- Unit

The control unit tells the rest of the computer’s system how to carry out a program’s instructions. It directs the movement of electric signals between memory and the ALU.

It also directs these control signal between the CPU and the input/output Devices.

Full Form of types of RAM

  • DRAM: Dynamic Ram
  • SRAM: Static Ram
  • MRAM: Magnetoresistive RAM

It stands for Random Access Memory. The memory is accessed randomly, that is any byte of memory can be accessed without touching the previous sequence of bytes.

RAM is the most common type of memory found in the computer and other other devices, such as printers.

R- Read
O- Only
M- Memory

Full Form of types of ROM

PROM: Programmable Read-Only Memory
: Erasable Programmable ROM
: Electrically EPROM

It stands for Read-Only Memory. ROM is designed to hold permanently stored programs installed by the computer manufacturer. ROM is non-volatile, which means none of your data is erased when you off the computer.
