:: Bus Speed

In order for the processor (brain) and the memory, audio, hard drive and other devices to talk they must be connected. This connection is referred to as the bus speed. They are wires that connect devices together in order to exchange information and send commands. This speed at which information can travel is knows as bus speed and can greatly affect the overall speed of the entire computer system. In a computer there are two forms of bus speed, the front side bus which controlls the high speed devices and the southside bus which controls the slower speed devices for example the floppy drive, and cd-rom drive.

:: Commercial Grade

Commercial grade generally refers to equipment designed for business use, is more expensive but is usually higher grade quality. Commercial Grade computers usually last longer, but are not sold to consumers.

:: Display Units

LCD Screen have really made portability possible. LCD screens use a verity of materials including polarized plastic, metal, lights ( led or florescent ) and glass. Main drawback of led are colors displayed, fast movement can look blurry on displays 8 milliseconds or slower, and price.

:: Form Factor

Form Factor ( AT, ATX, LPX ) is the shape and general design of a desktop computer. Form factors determine where the power supply is placed, motherboard, and other devices.

:: ISA Slot

ISA Slots are black, long and a much older design. ISA slots are not supported anymore.

:: PCI - Express

PCI-Express Slots are usually black, and thinner then a PCI slot. PCI-E has faster bus speed and is the new replacement for PCI slots.

:: PCI Slot

PCI Slots are still in use today. They are being replaced by PCI-E slots, but slowly due to the fact that most video, audio, network, and other cards are still standard PCI design.

:: Power Strip

A power strip has usually 4-7 plug-ins which allow multiple equipment to be plugged in at one time. Although companies boast that it saves equipment from lightning sticks, we suggest you not take this to heart. Many times we have seen these power strips fail. To protect your computer please get a UPS (Uninterruptible Power Supplies).

:: Power UPS

Uninterruptible Power Supplies is the consumers and business best way to protect there equipment from brownouts, blackout, and lightning. A UPS monitors electrical pulses constantly, and has a battery built in to allow the computer to shutdown. A UPS can be setup to automatically shut down the equipment, and save any changes. Consumers should consider purchasing these to protect there systems. A power strip is no substitute.

:: Processor / CPU

A CPU (Central Processing Unit) could be considered as the brain of the whole computer. A computer ability as well as speed depends greatly on this chip. A cup can consist of million and millions of resisters that work together to get a job done. The Pentium 4 Prescott had 125 Million resisters on a chip no bigger then a penny. A CPU is upgradeable, although in laptops it may be highly restricted to a few choices or none at all.

:: Scanner

Scanners analyze letters, pictures, or objects that are put on the flat bed and converts them to digital images for emailing, storing, or archival purposes. Some of our customers are using scanners to digitize all there family photos.

:: Video Card

Video cards not only convert images so the display unit can understand them, but also are the main focus for designers and gamers. When video quality counts, video cards are the first to be considered for upgrading. Video cards for desktop are becoming standard PCI-E compliant. The standard house hold needs only a 64MB or a 128MB video card, only gamers really need to consider a 256MB video card or up
