- 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.

- 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. -
