Terminology means Technical Definition, here are some terminologies used for computers, they are categorized alphabetically, either you scroll down the page until you reach the terminology you wants, or it would be easier to click the terminology you want from the list. I hope you like this page and make a good use of it, also there will be an updates in the future, you may visit it regularly.

Letter Z : ZModem - Zipping (Zip File) - Zip Drive                                                           

 

  ZModem

   Zmodem is an error-correcting protocol for modems. Modems that agree on using the Zmodem protocol send data in 512-byte blocks. If a block arrives and an error is detected, a "NAK" (negative acknowledgement) is returned and the block is resent.

 
  Zipping (Zip File)

   Zipping is the act of packaging a set of files into a single file or archive that is called a zip file. Usually, the files in a zip file are compressed so that they take up less space in storage or take less time to send to someone. Several popular tools exist for zipping: PKZIP in the DOS operating system, WinZip and NetZIP in Windows, MacZip for Macintosh users, and Zip and UnZip in UNIX systems. The result of zipping is a single file with a ".zip" suffix. Most zip files compress the included files.

   After you download or otherwise receive a zip file, you can extract (and, if necessary, uncompress) the original files before using them. Most software that you download from the Internet will arrive as a zip file. Typically, by double-clicking on a self-extracting zip file, it will automatically extract and store the individual files. One of these files is usually called the "setup.exe" file. Double-clicking on this file will cause the software to be installed as a selectable program in your operating system.

 
Selected Links
You can download an evaluation version of WinZip or try out NetZIP.
Shareware and freeware versions of various zip/unzip programs can be downloaded from shareware.com.
UNIX-based system users can download Zip and UnZip from the Info-Zip site.

 
  Zip Drive

   A Zip drive is a small, portable disk drive used primarily for backing up and archiving personal computer files. The trademarked Zip drive was developed and is sold by Iomega Corporation. Each Zip drive disk holds 100 megabytes of data or the equivalent of 70 floppy diskettes. (The disk actually holds 100,431,872 bytes.) The Iomega Zip drive comes with a software utility that lets you copy the entire contents of your hard drive to one or more Zip disks. (Copying 500 megabytes of data takes about 45 minutes and five Zip disks.)

   In addition to data backup, Iomega suggests these additional uses:

  • Archiving old e-mail or other files you don't use any more but may want to access someday
  • Storing unusually large files, such as graphic images that you need infrequently
  • Exchanging large files with someone
  • Putting your system on another computer, perhaps a portable computer
  • Keeping certain files separate from files on your hard disk (for example, personal finance files)

   As of September, 1997, the Iomega Zip drive retailed for well for about $150 with rebate coupons and you could buy six Zip disks at Sam's Club, a chain retailer in the U.S., for $70 (the regular retail price is about $20 a disk). The Zip drive can be purchased in either a parallel or a SCSI version. In the parallel version, a printer can be chained off the Zip drive so that both can be plugged into your computer's parallel port.

   The SyQuest EZ135 is a similar product, but review comparisons seem to slightly favor the Zip drive. Syquest also makes larger and more expensive removable (portable) disk drives that are worth considering if you have a more professional system.
