From W to Z

WAN
Wide area network, which is distributed over a large area and involves routing nodes. Compare to LAN.

wand
See wand scanner.

wand scanner
A handheld scanning device used as a contact bar code or OCR reader.

warm boot
One of two ways to boot the reader; compare to cold boot. A warm boot performs the power-on self test (POST) to ensure that the hardware and peripherals are operational, runs CONFIG.SYS and AUTOEXEC.BAT, and displays the DOS prompt. The contents of both conventional memory and the physical RAM drive (drive E) remain intact. You may warm boot the reader to execute startup files, such as AUTOEXEC.BAT, that have changed. You may also warm boot to start Interlnk.

wedge reader
A bar code reader that connects to a PC. The wedge lets you scan bar code and enters the data into the PC as if it were typed at the keyboard.

wide to narrow ratio
The comparison of the widest bar in a bar code symbol to the narrowest bar. Expressed as a ratio such as 2:1 or 2.5:1.

wireless LAN
Wireless local area network. A flexible data communication system implemented as an extension to, or alternative for, a wired LAN within a building or campus. Using electromagnetic waves, a WLAN transmits and receives data through the air, minimizing the need for wired connections. A WLAN combines data connectivity with user mobility, which enables mobile LANs through simplified configuration.

WMS
Warehouse management systems. Software that integrates mechanical and human activities with an information system to effectively manage warehouse business processes and direct warehouse activities. These systems automate receiving, put away, picking, and shipping in warehouses and can prompt workers to do inventory cycle counts. Most support radio-frequency communications, allowing real-time data transfer between the system and warehouse personnel.

WTP
Wireless Transport Protocol. WTP is a legacy protocol stack that provides robust wireless connectivity between 1100, 1700, 6400, 5900, and 6550 terminals and the associated controllers. WTP is also an efficient protocol stack that overcomes many of the limitations associated with assigning an IP address to each terminal. Large customers have selected WTP to minimize the impact of managing IP addresses.

X dimension
The width of the narrowest element in a bar code symbol. An element can be a bar or a space.

XMODEM
A protocol that allows you to send commands to and communicate through a modem.

XOFF
Defines a character that disables the transmission event. The receiving device sends XOFF when its receive buffers are nearly full of data. Older Intermec products may not include these protocol characters. Newer generation online reader products implement these protocol acronyms.

XON
Enables or disables XON/XOFF flow control and defines a character that reenables transmission when the device can receive data again after an XOFF. Older Intermec products may not include these protocol characters. Newer generation online reader products implement these protocol acronyms.

XON/XOFF
A type of software flow control for communication between digital devices. It stops the host from sending data when the device buffer fills up (XOFF) and starts it again when the buffer empties (XON).

Z dimension
The achieved width of the narrow elements, calculated as the average of the average narrow bar width and the average narrow space width.ank.
