Basic PC Anatomy
Understanding Graphic Cards
Dedicated graphics cards, which we will be discussing in this article, are needed if you
want to do 3D gaming or watch high definition movies. The GPU (Graphic Processing Unit)
is the most determinant feature of every graphics card when it comes to the overall
performance and speed. More ...
Understanding The Speed Of New Pci Express Data Bus
PCIe is intended to be used as a local interconnect only. As it is based on the existing
PCI system, cards, and systems can be adapted to PCI Express without any change in
software. The higher speeds on PCIe allow it to replace almost all existing buses. More ...
The Computers Back Connector Panel
So although the computer's back panel appears to be a complicated mess, each connector
has a specific shape, number and pins, and polarity key that allows only the proper
cable to be plugged in. If you get a nice comfortable feeling like your not smashing
pins when you plug a cable in, then you can feel secure that nothing will blow up. More ...
How Does Wireless Internet Work?
Just as we broke free from phone lines, we can now access the Internet from just
about anywhere via a wireless connection. Wireless Internet access is really much
simpler than most people think. This article briefly explains how it works. More ...
The Small Computer System Interface (SCSI)
SCSI is complicated to configure and troubleshoot with incompatibility between devices
being a common problem. To setup a SCSI system, you need to know which SCSI standard the
devices support. The host adapter must match the devices. More ...
Understanding Computer Memory
Understanding computer memory is important because your computer's memory is where the
action is. Sure your computer's central processing unit (CPU) may be the computer's brain,
but what good is a brain without memory? More ...
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 ...
How Does a Laptop Battery Work?
There is little difference in how a laptop battery works and how other device batteries work,
except that a laptop battery is more intelligent. An electronic circuit works with the laptop
hardware to manage the power that flows into the battery while recharging and the power that
flows out of each cell of the battery while discharging. More ...
Motherboard Form Factors
The "form factor" of a motherboard defines its dimensions. Make sure that the computer
case that you purchase can accommodate the motherboard. It is also wise to select a
motherboard with a commonly available form factor in case you need to replace it. Article
updated with more information. More ...
Basic CPU Architecture - Direct Memory Access Channels (DMA)
In early computers, all data transfers to and from main memory where routed through
the CPU. This is not efficient for devices that require high-speed access to main
memory. Direct Memory Access (DMA) allows a hardware device to bypass the CPU and
transfer data directly to and from main memory. More ...
Serial ATA Hard Drive
New computers will begin using the SATA (Serial ATA) interface to the hard disk. Some
new motherboards come with built-in SATA support. The SATA interface does not use
a ribbon cable. Instead, it uses a cable similar to a network cable with only seven wires. More ...
The AMD Athlon 64 Processor
AMD's Athlon 64 processor, released in September 2003, was their first 64-bit processor
targeted for the workstation market to compete with Intel's Pentium 4. AMD's first
64-bit processor was the Opteron, released earlier in April that same year, targeted
for the server market to compete with Intel's Xeon processor. More ...
