Computing devices Guide

Does the technical name of different element of a computer, such as MEMORY, processor, scare you off?

In the following paragraphs, we will be covering the majority of the hardware in regardless of the shape size (physical size of the actual computer casing)

Essential Computer Hardware includes

Hard Drive Drive
Graphic Card
Power Provide / Casing
Keyboard / Computer mouse
DVD Writer

Mainboard (Motherboard)

This is actually the biggest piece of hardware within the system. This is where many other essential components connect onto this, such as CPU, Ram, Hard drive, etc, to it. Modern mid-range mainboard usually includes add-on component such LAN interface, sound card and graphics greeting card.

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

Central Processing Device (CPU)

This is one from the computer hardware that determines the speed from the whole system. The other determining hardware are the RAM and Hard drive. Single Core CPUs are almost obsolete and therefore are much slower compared to their own Dual Core / Quad Primary counterparts.

Usually a numeric figure is stated and that’s the clock frequency, commonly referred to as the speed of the PROCESSOR. Usually the higher the time clock frequency, the faster your data could be processed.


Known as Arbitrary Access Memory, are memory potato chips where data are temporary saved. By storing the data upon RAMs, the CPU is in a position to process the data in a shorter period that leads faster execution of the instructions and tasks assigned towards the computer.

Usually a numeric figure (in Gb) is stated and that’s the physical size of data the RAM has the capacity to store.

Hard Disk Drive

This computing devices keeps all data permanently, unlike the RAM that will erase data if the computer is turn off. Comes in sizes of two. 5″ (for laptop) and 3. 5″ (for Desktop)

Usually a numeric figure (in Gb) is stated and is available in various capacity. A rough calculation Assuming the 4 min long music tune is stored in mp3 format and occupies 4mb worth of space within the hard disk. 160Gb will have the ability to store around 40, 000 tunes!

Graphic Card

As stated, this card is initially accountable for displaying images onto the keep track of. However, due to the higher rendering first-person-shooter games being created, gamers will demand their graphics card to become better than the CPU. This is because of the fact that the graphic card may handle all taxing gaming images that the CPU was unable to procedure. To meet up the needs, even graphics cards are heading dual core!

Power Supply Device (PSU)

The life of the actual computer! This computer hardware sends capacity to various devices, such as the actual mainboard, hard disk drives, and so on.

This is often the most overlooked hardware and it is frequently compromised due to spending budget constraints. However, by cutting down on obtaining a good PSU, risks such as electric surprise and under-current may occurs that could instantly destroy the mainboard along with other hardware by providing the incorrect current or voltage!!

Computer Outer shell / Chasis

Computer case may be the tough armor to protect the dedicated various computing devices.

Casing are important as they ventilate and regulate ventilation to prevent overheating of the fundamental computer hardware.

Optical Drives

Often called CD-ROM / DVD-ROM or DVD AND BLU-RAY Writers, this allows reading of numerous CDs/DVDs. ROM hardware are only in a position to read from CD / DVD AND BLU-RAY, while DVD Writers enables writing (copying of data) towards the discs.

The latest technology for Optical Drive happens to be Blu-Ray ROM will allows reading through of Blu-ray disc. Due towards the high cost, it is not widely contained in systems.


Is a visual display device that shows images generated through the graphic card. CRT monitors which are working today are using old technology which consumes more energy. Mainstream monitor manufactured are now mostly LCD because of their compact size and cheaper price to manufacture.

LCD monitors are available in various sizes, ranging from no less than 15″ to up to 70″!

Computer keyboard and Mouse

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

I hope that the above computer guide will help you in having a further understanding of computing devices.
