How to Build a Computer
Branded computers can offer both value and performance, yet parts are often short-spec
in one place or another. Sadly you'll often get a performance "bottleneck" such as a
slow graphics card, only a basic amount of memory, or a slimline motherboard with too
few upgrade slots. Luckily, computers are surprisingly easy to build. More ...
Power Supply Form Factors
The shape and physical layout of a power supply is called its "form factor". Power
supplies come in several industry standard form factors. Power supplies with the same
form factor are physically interchangeable. More ...
Hard Disk Drive Basics
On a hard disk, data is stored in thin, concentric bands. A drive head, while in one
position can read or write a circular ring, or band called a track. There can be more
than a thousand tracks on a 3.5-inch hard disk. More ...

updated with more information. More ...
Digital Video Interface (DVI)
Today's computers use LCD (Liquid Crystal Display) displays. LCDs are a digital
device. It makes little sense to convert the digital image data to analog just
to convert it back to digital to display on the LCD. To avoid this double
conversion, the DVI (Digital Video Interface) standard was developed. More ...
Solid State Drive (SSD) Basics
Why is a hard disk drive so slow compared to a solid state drive and why don't they just
get rid of the hard disk drive, and store everything in solid state memory? Since 2006
computer manufacturers have been producing Solid State drive based PCs. More ...
The Computer's Chipset
A computers memory and peripheral ports connect through two highly integrated chips called
simply the chipset. The chipset consists of a northbridge chip and a southbridge chip. More ...
