Computer Hardware Guide

Does the technical title of a distinct part of a computer, like RAM, chip, frighten you off?

In this Guide, We’ll be covering the Majority of the hardware in Whatever the shape size (physical dimensions of this computer casing)

Essential Computer equipment Contains

  • Mainboard
  • CPU
  • RAM
  • Hard Disk Drive
  • Graphics Card
  • Power Supply / Casing
  • Keyboard / Mouse
  • Monitor
  • DVD Writer

Mainboard (Motherboard)

This is the largest piece of hardware within the computer system. That is where many other essential components join onto it, for example, CPU, Ram, Hard Disk drive, and so forth. Modern mid-range mainboard generally will come with add on an element such as LAN jack, sound card and graphics card.

As other hardware connects to the mainboard, it’s very important to be certain that the mainboard bought is made of high calibre and contains the add-on element as mentioned in the paragraph above.

Central Processing Unit (CPU)

This is among the computer hardware that determines the rate of the entire system. Another determining component would be the RAM and Hard Disk Drive. Main Core CPUs are nearly obsolete and therefore are much slower in comparison to their Double Core / Quad Core counterparts.

Normally a numerical figure is said and that’s the clock frequency, commonly referred to as the speed of this CPU. Normally the higher the clock frequency, the quicker the information could be processed.


Called Random Access Memory, are memory processors where information is temporarily saved. By keeping the information onto RAMs, the CPU can process the information in a shorter interval which leads quicker execution of the directions and tasks delegated to the computer.

Normally a numerical figure (in Gb) is said and that’s the physical size of information the RAM can store.

Hard Disk Drive

This computer hardware retains all information indefinitely, unlike the RAM that will erase data when your computer is shut down. Comes in sizes of 2.5″ (for notebook ) and 3.5″ (such as Desktop)

Normally a numerical figure (in Gb) is said and comes in a variety of capabilities. A rough calculation Assuming a 4 minutes long music tune is saved in mp3 format also takes up 4Mb value of distance in the hard disk drive. 160Gb will have the ability to shop around 40,000 pieces of music!

Graphics Card

According to this card is originally responsible for displaying pictures on the screen. But as a result of large earning first-person-shooter games being generated, players will need their graphics card to be greater compared to the CPU. This is because of how the graphic card will manage all taxing gaming pictures that the CPU was not able to procedure. To fulfil the requirements, even graphics cards are moving dual-core!

Power Supply Unit (PSU)

The life of this computer! This computer hardware transmits power to several devices, like the mainboard, hard disk drives, etc…

That is often the most overlooked hardware and is often compromised as a result of funding limitations. But by cutting down getting a fantastic PSU, dangers like electrical shock and under-current can happens which could immediately destroy the mainboard and other hardware by supplying the incorrect voltage or current!!

Computer Casing / Chasis

Computer situation is the difficult armour to guard the dedicated different computer hardware.

The casing is significant since they ventilate and regulate air circulation to prevent overheating of their crucial computer hardware.

Optical Drives

Popularly called CD-ROM / DVD-ROM or even DVD Writers, this permits reading of different CDs/DVDs. ROM hardware will be only able to see from CD / DVD, whilst DVD Writers allows writing (copying of information ) into the disks.

The most recent technology for Optical Drive is now Blu-Ray ROM will enable the reading of Blu-ray disk. On account of this high price, it’s not widely contained in programs.


Can be a visual display unit that shows images created by the card. CRT monitors which are operating now are using mature technology that absorbs more power. Mainstream track manufactured is now largely LCD because of their compact dimensions and more affordable price to manufacture.

LCD monitors are available in a variety of sizes, which range from a minimum of 15″ to around 70″!

Mouse and keyboard

Is your hardware to enter commands and data to the computer.

I trust that the above computer manual will aid you in getting a further comprehension of computer hardware.
