Memory resident virus: A virus that stays in memory after it executes and after its host program is terminated. In contrast, non-memory-resident viruses only are activated when an infected application runs. XUL: Pronounced "zool." Short for Extensible User-Interface Language, a series of XML tags that allow different operating platforms to exchange data that describe a program’s user interface. XUL is designed to ease cross-platform (e.g., Windows, Mac and Linux) interface of applications, which traditionally would have been difficult to customize from one to another. Zeroconf:
Short for zero configuration, IP networking, a method of networking
devices via an Ethernet cable without requiring configuration and
administration. Zeroconf is able to allocate addresses without a DHCP
server, translate between domain names and IP addresses without a DNS
server, and find services, such as a printer, without a directory
service. The technology is intended for use in small networking
situations where there is a low-security need and where it is
inappropriate or impossible to establish a working IP network using
traditional technologies, such as DHCP and DNS. Disk
thrashing: In systems that use virtual memory,
the resulting condition of a hard drives being used excessively for
virtual memory because the physical memory (i.e., RAM) is full. (The
process of moving data into and out of virtual memory also is called
swapping pages) Disk thrashing considerably slows down the performance
of a system because data has to be transferred back and forth from the
hard drive to the physical memory. A sure sign that your computer is
thrashing is when an application stops responding but the disk drive
light keeps blinking on and off. |
