from Computer Hardware Guide Part

We
have covered some of the essential computer hardware in part 1 of our computer hardware guide. And now its for
the rest of the computer component.
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 figure
(in
Gb) is stated and comes in
various 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 demand their graphics card to be better than
the CPU. This is due to the fact that the graphic card will handle
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 various devices, such as the mainboard, hard disk drives,
etc.
This is often the most
overlooked hardware and is frequently compromised due to budget constraints. However, by cutting down on getting
a good PSU, risks such as electric shock and under-current may occurs which could instantly destroy the
mainboard and other hardware by providing the wrong current or voltage!!
S-Mall
Pte Ltd ensures that the PSU in the system are of high caliber and have been tested and proven to work with your
Custom Computer System

Optical
Drives
Commonly known as CD-ROM /
DVD-ROM or DVD Writers, this allows reading of various CDs/DVDs. ROM hardware are only able to read from CD /
DVD, while DVD Writers enables writing (copying of
data) to the discs.
The latest technology for
Optical 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 visual 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 compact
size and cheaper cost to manufacture.
