011
Which items need to be set up on SCSI drives?
Unique ID
Terminators
Which RAID level is known as "Disk Duplexing"?
RAID 1
ESD
Electrostatic Discharge
Three types of ESD are?
Upset Failures - causes an electrical componet to fail without causing any detectable physical damage.

Degradation Failures - take place when a componet is physically damaged by ESD, but still works-at least some of the time.

Catastrophic Failure - when the ESD damage is so severe that the componet is physically destroyed.
Before working on a PC?
Take a moment to touch the power supply every once in a while as you work to keep the same electrical potential as the PC.
CPU
Central Processing Unit or Microprocessor -performs all the calculations that take place inside a PC.
Every CPU has?
A Make
A Model
A Speed
A Package Type
RAM
Random Access Memory -stores programs and data currently being used by the CPU. Each piece of RAM is called a Stick.
EIDE
Enhanced Intergrated Drive Electrons -EIDE drives are inexpensive and easy to install. More than 95% of all PC's use EIDE drives.
SCSI
Small Computer System Interface -SCSI drives are generally faster and more expensive, so they usually show up only in high-end PC's such as network servers or graphics workstations.

Name the 4 types of parellel ports and their differences.
SSP (standard Parelle port) -can only send data to a printer.

Bi-directional -can send & recieve data, but it is slow by todays standards.

EPP (enhanced parellel port) -is a faster parellel port.

ECP (enhanced capabilities port) -It is the same as an EPP exect it can use DMA for an even faster transfer speed.
Parelle Port : LPT 1 , IRQ 7
