This ebook covers the certification examination good, so far as the subjects. yet so far as the data it comprises, i do not believe it's adequate to move the examination.

Most hard drives today use an internal technology called Integrated Drive Electronics (IDE). org). The two major ATA standards for a drive interface are serial ATA (the newer standard) and parallel ATA (the older standard). Parallel ATA, sometimes called the EIDE (Enhanced IDE) standard or the IDE standard, allows for two connectors on a motherboard for two data cables (see Figure 1-17). Each IDE ribbon cable has a connection at the other end for an IDE device and a connection in the middle of the cable for a second IDE device.

The most popular printers available today are ink-jet, laser, thermal, solid ink, and dot-matrix printers. The monitor and the printer need separate power supplies. Their electrical power cords connect to electrical outlets. Sometimes, the computer case provides an electrical outlet for the monitor’s power cord, to eliminate the need for one more power outlet.

Most computer ports are located on the back of the case (see Figure 1-4), but some cases have ports on the front for easy access.
