UNIT 2: COMPUTER SYSTEMS
Practical: Setting
up the System
M3
1.
Firstly, the client is left handed so
we changed the settings to a left handed mouse, this worked perfectly fine.
2.
We then set up a BIOS password, in
order to protect settings being changed, this again worked fine.
3.
To prevent viruses and Trojans, the
client required we set up the anti-virus software to scan once a week at 1pm.
This was also successful.
4.
To save electricity, the client asked
we set the PC to enter sleep mode after 10 minutes, this worked fine.
5.
Next, we set the desktop, fonts and
icons to be extra-large so the client could see them properly.
6.
Then we made sure the language was
set to English UK, so the client wouldn’t get confused with American versions
of English.
7.
We then put Open Office into the
start-up programs, so the client can find it and use it easily.
8.
Then we created a simple toolbar
entitles 'Basic Activities' within Open Office, so the client has perform
simple 'save', 'print', 'copy', 'paste' tasks without fuss.
9.
We were then asked to make sure there
were suitable shortcuts on the desktop for the client to find and use easily.
10.
Lastly, we made sure all applications
and shortcuts work perfectly with no error messages. All seemed to be correct.
11.
Remove the things you don’t want from
the start up panel (MSCONFIG)
Benchmarking Stages
1.
Download and install software
designed to benchmark your PC
2.
Close any other software you have
open on your computer.
3.
Run the software. The software should
prompt you to scan your computer. If the benchmarking software doesn't prompt
you, run the software manually.
4.
Read the results. You should see
information about things such as your processor speed, RAM usage, memory taken
and hard disk capacity.

Windows System Assessment Tool
The Windows System Assessment Tool
(WinSAT) is a module of Microsoft Windows Vista, Windows 7, and Windows 8 that
is available in the Control Panel under Performance Information and Tools. It
measures various performance characteristics and capabilities of the hardware
it is running on and reports them as a Windows Experience Index (WEI) score.
The WEI includes five sub scores: processor, memory, 2D graphics, 3D graphics,
and disk; the base score is equal to the lowest of the sub scores. WinSAT
reports WEI scores on a scale from 1.0 to 5.9 (for Windows Vista), 7.9 (for
Windows 7), or 9.9 (for Windows 8).
Performance metrics:
Computer performance metrics include
availability, response time, channel capacity, latency, completion time,
service time, bandwidth, throughput, relative efficiency, scalability,
performance per watt, compression ratio, instruction path length and speed up.
CPU benchmarks are available.
The performance of any computer
system can be evaluated in measurable, technical terms, using one or more of
the metrics listed above. This way the performance can be
- compared relative to other systems
or the same system before/after changes
