| IDE | Integrated drive electronics,a method of disk drive manufacturing. |
| Enhanced IDE (EIDE) | allows for two IDE channels that can support two devices. |
| AT Attachment (ATA) | the At revers to IBM AT. Computer where this interface was first used. |
| ATA-33 | An extension to the ATA interface (IDE) that will effectively double the top data transfer. 33 MBPS. |
| SCSI | small computer interfaces standard interfaces for hard drives and CD-ROM drices , it can be used for scanners. |
| Millisecond | One thousandth of a second usually used to measure the access speed of hard-drives. |
| System Hang | when a program fails it has the opportunity to display an error or diagnostic message, only works if application doesnt work. |
| POST | power-on-self test, A group of ROM BIOS diagnostic, programs to check the system |
| Cold Boot | to turn on a computer or to restart a computer by turning it off, waiting a few seconds and truing it on again. |
| Warm Boot | to restart a computer by pressing control-alt-delete. |
| Boot Disk | A write-protected floopy disk that contains the computers system start-up directions. |
| Boot Sector | a protion of a disk that contains the coded instructions tfor the operating system to start the computer. |
| Safe mode | this is a widndoes 96 mode that is automatically loaded if windows is crashed during start-up |
| Scanner | this device is used for copying image from a physical source onto a computer |
| LPT1 | the label used in MS-DOS assigned to parrelel port one. |
| COM1 | the label used for MS-dos asigned serial port |
| MTBF | mean time between failures shown in hours. |
| Drive Interface | the interface where connections are made to connect to a drive to a computer system. |
| LUN | <storage> (LUN) A 3-bit identifier used on a SCSI bus to distinguish between up to eight devices (logical units) with the same SCSI ID. |
| Display Adapter | A board that plugs into a personal computer to give it display capabilities. The display capabilities of a computer, however, depend on both the logical circuitry (provided in the video adapter) and the display monitor. A monochrome monitor, for example, cannot display colors no matter how powerful the video adapter. |
| VGA | Abbreviation of video graphics array, a graphics display system for PCs developed by IBM. VGA has become one of the de facto standards for PCs. In text mode, VGA systems provide a resolution of 720 by 400 pixels. In graphics mode, the resolution is either 640 by 480 (with 16 colors) or 320 by 200 (with 256 colors). The total palette of colors is 262,144. |
| AT commands | Short for advanced technology, the AT is an IBM PC model introduced in 1984. It includes an Intel 80286 microprocessor, a 1.2MB floppy drive, and an 84-key AT keyboard. |
| 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. For example, a telephone conversation is asynchronous because both parties can talk whenever they like. If the communication were synchronous, each party would be required to wait a specified interval before speaking. |
