Computer Hardware Guide

Does the technical name of distinct component of a computer, such as Ram, processor, scare you off?

In this article, we will be covering most of the hardware in regardless of the form size (physical size of the computer casing)

Laptop Graphics Card

Essential Computer Hardware consists of

Mainboard
Cpu
Ram
Hard Disk Drive
Graphic Card
Power supply / Casing
Keyboard / Mouse
Monitor
Dvd Writer

Mainboard (Motherboard)

This is the biggest piece of hardware in the system. This is where varied other valuable components connect onto it, such as Cpu, Ram, Hard Disk drive, etc, to it. Contemporary mid-range mainboard commonly comes with add-on component such Lan port, sound card and graphics card.

As other hardware connects to the mainboard, it is important to ensure that the mainboard purchased is of high caliber and has at least the add-on component as stated in the paragraph above.

Central Processing Unit (Cpu)

This is one of the computer hardware that determines the speed of the whole system. The other determining hardware are the Ram and Hard Disk Drive. Single Core Cpus are approximately obsolete and are much slower compared to their Dual Core / Quad Core counterparts.

Usually a numeric form is stated and that is the clock frequency, generally known as the speed of the Cpu. commonly the higher the clock frequency, the faster your data can be processed.

Ram

Known as Random access Memory, are memory chips where data are temporary stored. By storing the data on Rams, the Cpu is able to process the data in a shorter period which leads faster performance of the instructions and tasks assigned to the computer.

Usually a numeric form (in Gb) is stated and that is the physical size of data the Ram is able to store.

Hard Disk Drive

This computer hardware keeps all data permanently, unlike the Ram which will erase data if the computer is shut down. Comes in sizes of 2.5" (for laptop) and 3.5" (for Desktop)

Usually a numeric form (in Gb) is stated and comes in varied capacity. A rough calculation Assuming a 4 min long music song is stored in mp3 format and takes up 4mb worth of space in the hard disk. 160Gb will be able to store around 40,000 songs!

Graphic Card

As stated, this card is initially responsible for displaying images onto the monitor. However, due to the high rendering first-person-shooter games being produced, gamers will question their graphics card to be better than the Cpu. This is due to the fact that the graphic card will cope all taxing gaming images which the Cpu was unable to process. To meet up the demands, even graphics cards are going dual core!

Power supply Unit (Psu)

The life of the computer! This computer hardware sends power to varied devices, such as the mainboard, hard disk drives, etc.

This is often the most overlooked hardware and is frequently compromised due to allocation constraints. However, by cutting down on getting a good Psu, risks such as galvanic shock and under-current may occurs which could promptly destroy the mainboard and other hardware by providing the wrong current or voltage!!

Computer Casing / Chasis

Computer case is the tough armor to safe the dedicated varied computer hardware.

Casing are important as they ventilate and regulate air flow to prevent overheating of the valuable computer hardware.

Optical Drives

Commonly known as Cd-Rom / Dvd-Rom or Dvd Writers, this allows reading of varied Cds/Dvds. Rom hardware are only able to read from Cd / Dvd, while Dvd Writers enables writing (copying of data) to the discs.

The most recent technology for optic Drive is currently Blu-Ray Rom will allows reading of Blu-ray disc. Due to the high cost, it is not widely included in systems.

Monitor

Is a optic display unit that shows images generated by the graphic card. Crt monitors that are working today are using older technology which consumes more power. Mainstream monitor manufactured are now mostly Lcd due to their contract size and cheaper cost to manufacture.

Lcd monitors come in varied sizes, ranging from a minimum of 15" to up to 70"!

Keyboard and Mouse

Is the hardware to input data and commands into the computer.

I hope that the above computer guide will aid you in having a supplementary understanding of computer hardware.
