Basic PC Anatomy
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 ...
The original 4.77 Mhz 8088-based IBM PC released in 1981 was built with over 100 discrete
logic chips. To lower the cost of manufacturing, the logic was integrated into a couple of
chips that were used together as a set. They became referred to as a chipset. More ...
The Universal Serial Bus
In 1996 the Universal Serial Bus (USB) was developed to replace the serial and parallel
ports. Today, the USB port is used to connect scanners, digital cameras, and external
storage devices like CD-RW drives. More ...
Hard Disc Fundamentals
This article describes the main technical fundamentals of Hard Disc Drive and its operation.
I focus my attraction on the particular perspective of describing Physical and Logical view
of HDD. This article also brings out the technology wise company working on this hard disc
drives and this related technology. 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 ...
What is Bluetooth?
Bluetooth is a wireless technology designed for short range data communications Two or more
Bluetooth devices establish a connection and form a small network known as a Piconet. More ...
Installing an Optical Drive
Optical drives read (and may write) CDs; DVDs, HD DVDs; and BluRays. Virtually every
modern PC contains an optical drive (either internally or externally), used as a media
player, for installing new software, or as large capacity storage medium for computers.
Installing your optical drives is an easy process that requires a bit of attention to
detail. Here?s an easy-to-follow-installation guide. 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 Chemistry of Laptop Batteries Explained
Laptop batteries come in all shapes and sizes also differ in their chemical composition. The
chemistry of a battery refers to the chemical make-up of the cells inside the outer casing.
This artilce explains the most common chemistries used in laptop batteries. 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 ...
SD (Secure Digital) Memory Card Basics
SD cards come in a variety of sizes, storage capacities, and transfer speeds.
This makes it confusing for users to choose the correct memory card for
their products. This article touches on the SD technologies to help you
get the correct SD memory card. 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 ...
