A time-out period during which a CPU or bus lies idle. Wait states are sometimes required because different components function at different clock speeds. For example, if the CPU is much faster than the memory chips, it may need to sit idle during some clock cycles so that the memory chips can catch up. Likewise, buses sometimes require wait states if expansion boards run slower than the bus.
A zero wait state system is one in which the microprocessor runs at the maximum speed without any time-outs to compensate for slow memory. Wait states can be avoided by using a variety of techniques, including page-mode memory, interleaved memory, a burst mode, and memory caches.
- walled garden
On the Internet, a walled garden refers to a browsing environment that controls the information and Web sites the user is able to access. This is a popular method used by ISPs in order to keep the user navigating only specific areas of the Web, whether for the purpose of shielding users from information — […]
On computers that use a desktop GUI, wallpaper is the monitor pattern or picture or other graphic representation that forms the background onto which all the icons, menus and other elements of the operating system are displayed and moved around. An operating system will typically come with pre-installed images to set as the wallpaper and […]
The act of making chalk marks on outdoor surfaces (walls, sidewalks, buildings, sign posts, trees) to indicate the existence of an open wireless network connection, usually offering an Internet connection so that others can benefit from the free wireless access. The open connections typically come from the access points of wireless networks located within buildings […]
Pronounced wayrz or wayrss. Commercial software that has been pirated and made available to the public via a BBS or the Internet. Typically, the pirate has figured out a way to de-activate the copy-protection or registration scheme used by the software. Note that the use and distribution of warez software is illegal. In contrast, shareware […]
The act of driving around in a vehicle with a laptop computer, an antenna, and an 802.11 wireless LAN adapter to exploit existing wireless networks. Set on promiscuous mode, the wireless adapter, typically a NIC, will receive packets within its range. Wardriving exploits wireless networks that have ranges that extend outside the perimeter of buildings […]
