Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/96001101.asp Early PCs used a bus called Industry Standard Architecture (ISA). ISA devices cannot share resources, each ISA device must have its own IRQ. In 1993, Microsoft and Intel developed Plug and Play (PnP) to solve this problem.

If we don't take away that heat as fast as it's created, that CPU will fry! Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/96030802.asp In this article, I'm going to reveal in plain English what a driver is, why we need drivers, and exactly where the drivers are hiding. To give you a basic understanding, I'm going to go back, way back, to the early days of computers. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/96071801.asp 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. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/96092902.asp 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.

It seems like a simple process, but in reality your request passed through many layers of software before reaching your printer. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/96110201.asp Via was founded in 1997. Via introduced the VP1 chipset to compete with Intel's 430 series. The VP1 offered support for EDO, BEDO and SDRAM as well as UltraDMA ahead of Intel. Today Via is one of the worlds largest chipset manufacturers. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/97051500.asp 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? Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/97102030.asp 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. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/97102410.asp Although most people think the microprocessor is the most important part on a computer's motherboard, the 'chipset' is equally important. With the introduction of the Athlon processor, AMD gained the technilogical lead. AMD processors and chipsets have always held the advantage in value. Tue, 18 Dec 2007 15:25:37 GMT http://bucarotechelp.com/computers/anatomy/97112880.asp 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. Tue, 18 Dec 2007 15:25:37 GMT
