GeekWorldWideConquest: How to build a computer, with computer builds.

Computer Components and Definition

Case/Tower
This is known as the computer cabinet, which protects, holds and organize the parts in the computer.
Make sure you clean the case and organize
the cables to improve airflow.

Motherboard
A printed circuit board, with connectors
into which other circuit boards can be slotted.

CPU
CPU is the central processing unit, (GPU)
is the brain of you computer,
that carries commands for you computer.

GPU (Video Card)
GPU is the graphics processing unit,
(GPU) that accelerates 3D or 2D
graphics rendering.

RAM
Random access memory (RAM) works like this,
every time open a program,
it gets loaded from the hard drive into the RAM.
This is because reading data from the
RAM is much faster
than reading from the hard drive.

HDD/Hard Drive
Basically, it works like your brain,
it stores data that you downloaded
from the internet, for ex.
lets say you almost drown when you where little you,
will remember for the rest of your life.
The only big difference is that you can
delete data of your hard drive.

Disk Drive/Optical Drive
A device that allows a computer
to read from and write to computer disks,
with ether a laser light or electromagnetic waves.

SSD/Solid State Drive (Not Required)
The Solid State Drive is
basically ram on you Hard Drive, but a little different.
They save memory, and much faster
then your old Disk Hard Drive.

PSU/Power Supply
The power supply unit (PSU) converts
AC to DC electric,
for the motherboard and all the
components in your computer.

Frequently asked questions

What is a multicore CPU?

Spoiler (Click to Hide)

You can only use operating frequency to compare the ultimate CPU power between two chips of the exact same architecture. So comparing a 3.2Ghz operating frequency of a single core P4 to a 2.56 Ghz speed of a dual core chip is not at all an apples to apples comparison as you've guessed. The "speed" of a CPU that most people refer to is more accurately described as it's overall processing power.

A dual core 2.56 CPU still runs at 2.56Ghz....period. However, it has two "mostly" independent cores that can work on separate tasks at the same time. So while the operating frequency doesn't change, the overall processing power is theoretically doubled. BUT, since there are parts of the CPU architecture that are shared by both cores, the reality is that a Dual core CPU might give you 1.6 times (or so) the overall processing power of a single core at the same operating frequency.

Hyperthreading, without getting overly technical, is a way to try to do the same type of thing with one physical core. Hyperthreading, or "Parallel Processing" tries to create "virtual" cores and separates the processing capability of a single core into multiple tasks ("threads"). You can actually have a dual core (or any number of core) CPU that ALSO has Hyperthreading abilities.
