1. The manufacturer is Dell. The model is OptiPlex GX280 (DHM).
2. The manufacturer is Intel. The model number is
Pentium 4 HT 3.0 SL6WK.
3. 3GHz.
4. Hz abbreviates Hertz. For the CPU, Hertz, or the
number of pulses per second, measures the clock rate of the CPU. The clock rate
is the
"Frequency of a computer's internal electronic clock. Every computer
contains an electronic clock, which produces a sequence of regular electrical
pulses used by the control unit to synchronize the components of the computer
and regulate the fetch–execute cycle by which
program instructions are processed.
A fixed number of time pulses is required in
order to execute each particular instruction. The speed at which a computer can
process instructions therefore depends on the clock rate: increasing the clock
rate will decrease the time required [by the CPU] to complete each particular
instruction."

ÒThe clock rate of a CPU is normally determined by the frequency of an oscillator crystal.
A crystal
oscillator frequency reference typically is synonymous with a
fixed sinusoidal waveform, a clock rate is that frequency reference translated
by electronic circuitry into a corresponding square wave pulse [typically] for
digital electronics applications."

5. They are DIMMs.
ÒThe SIMMs pins on either side are connected to each other while
DIMM pins are independentÓ
(Souce: http://www.differencebetween.net/technology/difference-between-simm-and-dimm/)
ÒThe gold or tin pins on the lower edge of the front and back of a
SIMM are connected, providing a single line of communication paths between the
module and the system.
The pins on a DIMM are not connected, providing two lines of
communication paths between the module and the system, one in the front and one
in the back.Ó

6. 1024MB.
7. There is a separate video card. Hence the
graphics/video is not ÒintegratedÓ in the motherboard.
8. Graphics processing unit.
9. The manufacturer is Hitachi. The model number is Deskstar 1C35L090 AVV207-0.
10. Two.
11. 80.0 GB.
12. 100-120V or 200-240V. [This is only the
input voltages; output voltages are more important, as they feed into machine.—JOR]
13. 3V.
14. The manufacturer is NEC Corporation. The model
number is ND-2100A.
15. 8x

16. The PC has a power supply that converts alternating current to direct current. The PC can be used all over the world because it operates on both 100-120V and 200-240V voltage.
