| IDE | intergrated drive electronics. A method of disk drive manufacturing that allocates all the required controller circuitry in the drive itself |
| EIDE | allows for 2 IDE channels that can each support 2 devices |
| ATA | more commonly known as IDE, the AT refers to the IBM-AT computer where this interface was 1st used. |
| ATA-33 | an extension to the ATA interface (IDE) that will effectively double the top data transfer speed up to 33 Mbps Ultra IDE |
| SCSI | small computer standard interface a standard data pathway used mostly for hard drives and CD-ROM drives, but also a common interface for scanners and sometimes printers. |
| Millisecond | one thousandth of a second usually used to measure the access speed of hard drives |
| system hang | program fails, it displays an error message. |
| POST | power on self test a group of ROM BIOS dianostic tests that are performed on the system each time it is powered up. |
| Cold Boot | turning off a computer. wait a few then turn it back on |
| warm boot | Ctrl+Alt+delete |

| safe mode | goes to this if Windows crashes during boot up |
| scanner | copies an image from a physical source into a computer |
| LPT1 | MS-DSO parallel port 1 |
| COM1 | MS-DSO serial port 1 |
| MTBF | meantime between failures (hrs) failure of a device |
| drive interface | a collection of electrical and logical connections between a hard drive and a PC. |
| LUN | a unique sub-device identifier that enables you to have up to 7 sub-devices per single SCSI ID |
| display adapter | goes intoa expanion bus slot. and is compatible with a video monitor. |
| VGA | a graphics display system for PCs developed by IBM. VGA has become one of the de facto standards for PCsVGA uses analog signals rather than digital signals. |
| AT commands | the modern commands set used on most modems |
| asynchronous | Not synchronized; that is, not occurring at predetermined or regular intervals. The term asynchronous is usually used to describe communications in which data can be transmitted intermittently rather than in a steady stream. |
