A Guide To Building Your Own PC
What do you need to build your own custom computer? Believe it or not, it's not as complicated as it seems. The processor you choose usually determines which motherboard you select. Motherboards are designed to work with specific CPUs, indicated by the type of socket that the processor fits into. More ...
The Hard Disk Drive vs. The Solid State Disk
Much has been written about solid state disks (SSDs) becoming the next big thing1 in the IT industry. But as to whether or not we have enough knowledge of how it will revolutionize the industry is a different question. How much do we really know about SSDs? More ...
Understanding Your PC's CPU Clock Speed and Front Side Bus
The CPU or Central Processing Unit is the brains of any computer and the two major manufacturers are Intel and AMD or Advanced Micro Devices. For many years Intel CPUs were found in nearly all PCs. And now the Intel is found in most systems but the newer Athlon class CPU from AMD have taken a large chunk of the CPU market. More ...
Hardware Resources Explained
Hardware devices, such as modems, network circuits, sound circuits, and so on, require system resources such as Interrupt Request (IRQ) lines, Input/Output Port (I/O) addresses, Direct Memory Access Channels (DMA), and a range of Memory Addresses for storing code and data. Each device needs its own set of resources. If two devices attempt to use the same resource, your system may lock up or crash. More ...
Basic Computer Thermodynamics
Picture the CPU of a computer cooking away because the designer wants to push too much power through a small piece of silicon. If we don't take away that heat as fast as it's created, that CPU will fry! More ...
1G, 2G, 3G, and 4G Cellular Wireless Standards
The meaning of the terms 3G and 4G have been made very confusing because some wireless carriers have built new high-speed 4G networks from the ground up while other wireless carriers have chosen to doctor-up their 3G service and market it as 4G. More ...
PC Disk File Systems
The first PC file system, called FAT because it used a File Allocation Table, was developed in the early 1980?s for floppy disks. The File Allocation Table, a map of the location of files on the disk, is located near the beginning of the disk. 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 ...
Five Types of HDMI Cables
There are different types of HDMI cables, some are technologically more enhanced and some are designed for specific PCs and TVs, so it's important that you get to know about the various types. More ...
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 ...
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 ...
All About Your Computer's BIOS
Are you confused by the computer BIOS? The BIOS is a fundamental component of any PC and if you really want to get into the guys of a computer, it?s good through understanding what BIOS Is all about. 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 ...
Hard Drives - ATA versus SATA
with data rates hitting the 133MB / sec mark the parallel ATA standard is maxing out, thus industry leaders got together and came up with a new standard known as Serial ATA (SATA). More ...
