-
- Z
-
-
- Z80
- A common 8-bit Zilog microprocessor, particularly used in old CP/M systems.
-
-
- Z85C30
- The Zilog 85C30 SCC.
-
-
- Zero
- The binary or decimal digit represented by '0' indicating the absence of a
- value or a 'false' result in a logic operation.
-
-
- Zero-bit
- A 0-bit, representing binary zero.
-
-
- Zero divide
- A processor exception that occurs when a program tries to divide something by
- zero. In mathematics and programming the result is undefined so after catching
- this error TOS normally returns control back to the program making the result
- random garbage. See Exception vectors, Bombs.
-
-
- Zero insertion force - ZIF
- A type of socket for integrated circuit devices in which a lever with a cam
- action is incorporated to permit a device to be inserted or removed without
- applying pressure to the pins. Often used in EPROM blowers.
-
-
- Zero suppression
- An operation to eliminate zeros that have no significance from numbers before
- they are displayed, e.g. to change 0001.200 to 1.2. Sometimes other characters
- are substituted, especially on machine printed cheques, as in ***1.2. This is
- a typical spreadsheet function.
-
-
- ZIF
- Zero Insertion Force.
-
-
- ZIL
- Zigzag In-Line. An integrated circuit package where alternate pins from a
- single row are bent in opposite directions to form a zigzag.
-
-
- Zilog 85C30 SCC
- A dual standard, multi-protocol data communications chip in a 44-pin PLCC
- package on the TT and Falcon providing two serial ports (A and B). It has an
- asynchronous transfer rate of about 250 Kbits per second and a synchronous
- rate of 1 Mbit per second. See SCC ports.
-
-
- ZIP
- A file compression format with the .ZIP file name extender. It has the
- advantages of processing files very quickly with large compression ratios,
- especially with the 'deflate' method.
-
-
- ZIP
- Zigzag In-Line Package. Synonymous with ZIL.
-
-
- Zmodem
- A data transfer protocol using Xmodem with CRC-16 or CRC-32 and Ymodem
- technology but providing greater reliability, throughput speed, file
- management and error recovery. Of particular importance is that any aborted
- file transfer can be resumed from the same point on another occasion.
-
-
- ZOO
- A file compression format with the .ZOO file name extender common on many
- systems especially IBM PCs and UNIX.
-
-
- Zoom
- In computer graphics, to change the size of all or part of the elements of a
- display, usually to magnify or enlarge.
-
-
- Zoom box
- See Full box.
