Refers to the necessary
specifications your computer
must have in order to use the
software or hardware.

AND SYSTEMS
It is important to check system requirements for
hardware devices.
Most hardware and software products have the
system requirements printed on the side or
bottom of the product packaging. them down on
a piece of paper.

AND SYSTEMS
It is a good idea to first find out exactly what your
systems specifications are and write them down
on a piece of paper.

AND SYSTEMS
The important information to record includes:
1. Operating System (i.e.Windows XP, SP 2 or Mac
OS X 10.3.8)
2. Processor Speed (i.e. Pentium 4, 3.2 GHz or
Power PC G5, 2.0 GHz)
3. Memory, a.k.a. RAM (i.e. 512 MB)

AND SYSTEMS
The important information to record includes:
4. Graphics Card (i.e. ATI Radeon 9800 w/ 256 MB
video memory)
5. Hard Disk Space (i.e. 80 GB available)
6. I/O Ports (i.e. USB, Firewire, Serial, Parallel,
SCSI,VGA, DVI ports)

AND SYSTEMS
The performance of a computer depends on four
factors:
1. The speed and architecture of its processor or
"central processing unit" (CPU),
2. How much random access memory (RAM) it has,
3. Its graphics system; and
4. Its internal hard drive speed and capacity.

AND SYSTEMS
PROCESSOR SPEED AND ARCHITECTURE
The speed of a computer's processor chip
(technically known as its "clock speed") is
measured in gigahertz (GHz), with the fastest
modern processors currently running at up to
4.7GHz.

AND SYSTEMS
For most computing tasks, including web
browsing, sending e-mails, word processing and
spreadsheet work any processor running at 1GHz
or more remains perfectly sufficient.

AND SYSTEMS
For applications such as video editing, 3D graphics
work and (for the majority of "power users")
playing computer games, higher processor speeds
is highly required.

AND SYSTEMS
The architecture of a processor is the most
important factor to determine its performance,
and refers to its basic design and complexity.

AND SYSTEMS
CACHE is a form of very fast memory integrated
into the processor chip, and used to store up
instructions (work for the processor) so that it has
to slow down as little as possible between tasks.

AND SYSTEMS
CACHE is measured in megabytes (MB), with (for
example) low-end Celeron processors having as
little as 0.25MB of cache (256KB), and high-end
Itaniums having up to 24MB.

AND SYSTEMS
FRONT SIDE BUS (FSB) SPEED is a measure of
how fast a microprocessor communicates with the
computer's main circuit board (or "motherboard")
into which it is physically connected.

AND SYSTEMS
The higher the measure the better for overall
performance, with FSB speeds currently ranging
from 533MHz (still perfectly sufficient for the vast
majority of applications) up to 1600 MHz.

AND SYSTEMS
RAM
The more RAM a computer has the faster and
more effectively it will operate.

AND SYSTEMS
RAM
RAM is measured in megabytes (MB) and
gigabytes (GB). Just how much RAM a computer
needs depends on the software it is required to run
effectively.

AND SYSTEMS
RAM
A computer runningWindows XP will usually
function quite happily with 1GB of RAM, whereas
twice this amount (i.e. 2GB) is the realistic
minimum for computers runningWindows 7.

AND SYSTEMS
GRAPHIC SYSTEM
Determines how well a computer can work with
visual output.

AND SYSTEMS
GRAPHIC SYSTEM
Graphics systems can either be integrated into a
computer's motherboard (onboard graphics, or
plugged into the motherboard as a separate "video
card".

AND SYSTEMS
HARD DRIVE SPEED AND CAPACITY
Today 40GB is an absolute minimum hard drive
size for a new computer running Windows 7, with a
far larger capacity being recommended in any
situation where more than office software is going
to be installed.

AND SYSTEMS
Two key factors that determine the speed of
traditional, spinning hard disks:
1. Rotational velocity of the physical disk
2. Interface used to connect it to the computer's
motherboard

AND SYSTEMS
In rotational velocity of the physical disk , the
faster the disk spins, the quicker data can be read
from or written to it, hence the faster the disk the
better .

AND SYSTEMS
Most desktop hard disks run at either 5400 or 7200
rpm, whilst most laptop hard disks run at 4200 or
5400.

AND SYSTEMS
Three types of interface:
1. Serial AdvanceTechnology Attachment (SATA)
2. Integrated Device Electronics (IDE)
3. SCSI

AND SYSTEMS
Serial AdvanceTechnology Attachment (SATA) is
the most modern and now pretty much the norm
on new PCs .

AND SYSTEMS
Integrated Device Electronics (IDE) is also known
as UDMA (Ultra Direct Memory Access). It is a
slower and older form of interface.

AND SYSTEMS
SCSI stands for Small Computer System Interface.
The oldest but in it most modern variant is still the
fastest disk interface standard.
