Computer Hardware Guide

Does the computer name of the various components of the computer work, such as RAM, the processor?

This article covers most of the hardware with the form size (physical size of the computer cover)

Basic Computer Hardware


DVD Writer

This is the biggest hardware item in the system. This is where you need to connect to other other essential components such as CPU, RAM, hard disk drive, and so on. The modern medium-sized motherboard usually comes with an accessory component such as a LAN port, a sound card, and a graphics card.

Since other hardware is connected to the system board, it is important that the purchased motherboard is large calibrated and contains at least the components included in the above component.

Central Processing Unit (CPU)

This is one of the computer hardware that determines the overall system speed. The other dominant hardware is RAM and hard drive. One-processor CPUs are almost obsolete and are much slower than Dual Core / Quad Core.

Generally, there is a numeric figure, and this is the clock frequency usually called processor speed. Generally, the higher the clock frequency, the faster the data can be processed.


A memory chip known as Random Access Memory, where the data is stored temporarily. By storing data stored on RAM, the CPU can process the data in a shorter time, which will quickly execute the instructions and tasks assigned to the computer.

Generally, a numeric number (in Gb) is specified, and this is the physical size that RAM can store.

Hard Disk

This computer hardware keeps all data in the process, unlike RAM, which will erase the data when the computer is shut down. 2.5 "(laptop) and 3.5" (desktop) dimensions

Usually it is a numeric number (Gb) and has different capacities. A rough calculation If we assume that a 4 minute music song is stored in mp3 format, we will add 4 MB to the hard disk. 160Gb can store about 40,000 songs!

Graphic Card

As mentioned earlier, this card is originally responsible for displaying images on the monitor. However, the great rendering of the first personal-shooter games makes gamers ask for the graphics card to be better than the CPU. This is because the graphics card will handle all the tax gambling that the CPU could not process. To meet your needs even graphics cards use dual core!

Power Supply (PSU)

The Life of Your Computer! This computer hardware includes a variety of devices, such as a motherboard, a hard disk drive, and so on. Feed.

This is often the most disregarded hardware and is often compromised by budgets. However, by reducing the power supply, there may be electric shocks such as an electric shock and a low-current current that can immediately destroy the motherboard and other hardware if it is in the wrong power or voltage supply.

Computer Case / Case

Computer case is a toug armor that protects various computer hardware.

Cover is important as it ventilates and controls airflow to prevent overheating of basic computer hardware.

Optical Drives

Generally, CD-ROMs, DVD-ROMs, or DVD writers are known to read different CDs / DVDs. ROM hardware is only read from CD / DVD, while DVD burners allow data to be copied to discs.

The latest technology of the optical drive is currently Blu-ray ROM, which allows reading Blu-ray discs. Because of the high costs, it does not belong to the systems.


Visual display unit that displays graphics generated by a graphics card. Current CRT monitors use older technology that consumes more power. Manufactured mainstream monitors are mostly LCDs due to compact size and cheaper manufacturing costs.

LCD monitors are of different sizes, minimum 15 "to 70"!

Keyboard and Mouse

Hardware input data and commands to the computer.

I hope this computer guide helps you better understand computer hardware.
