Term	Description
W3C	World Wide Web Consortium - Organization dealing with the standardization of technologies that use the Internet, primarily WEB. It operates through working groups of members which create and maintain WWW standards, or better to say the recommendations, which are very important because whoever does not accept them soon in the Internet world becomes irrelevant.
Web Browser	Program support (software) that allows the user to view the website and multimedia content associated with them. Its quality is reflected in the speed of page impressions and compliance with W3C recommendations.
Webcrawler	Program to search for content online (search engine).
webm	Open royalty-free video codec (.webm) specification based on the contributions of Amazon, Cisco, Google, Intel, Microsoft, Mozilla and others, along with binding specifications for media format, content encryption and adaptive streaming, thereby creating opportunities for next-generation media experiences.
webp	Image format (.webp) that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster. Supports animated content.
WIA TWAIN	Windows Image Acquisition - WIA uses a common dialog for all devices while TWAIN uses a dialog created by the device manufacturer. Practically speaking, this almost always means that the TWAIN dialog will provide more options and advanced control over the device. TWAIN works on Windows, Linux and Mac. WIA using Windows ME or Windows XP and later OS. In general, when a device supports both TWAIN and WIA, TWAIN is better for scanners and WIA is better for acquiring images from cameras and video devices. Not all devices come with TWAIN support.
Wildcard	Special characters in operating systems or programming to 'replace' any character or name. See under 'Joker'.
Windows PE WinPE	Microsoft Windows Preinstallation Environment - Software tools that enable software providers to support the boot-optical media in Windows environment incorporating installation procedure that will allow the installation of software on their computer, but also make a special feature of the program's support can run directly from an optical media regardless on the hard disk. This example used by companies that produce antivirus program support to help with the optical media could examine the state of the hard drive of your computer. In addition to this solution is mainly reserved for companies, one of the free solutions available to everyone is a BartPE (Bart's preinstalled Environment - bootable live windows CD / DVD).
WINS	Windows Internet Naming Service - Windows system that determines which IP address is associated with a specific computer on the network. Adjusted when setting the parameters of network cards one of which is the IP address of the WINS server that the noun it every computer that uses his services is entered in its noun table about facilitating communication between computers.
World Wide Web	WWW or Web - Files placed on servers around the world that combines multimedia, image, and text content, and where the work is based on hypertext (see 'HTML'), in which the selection of a word or image is automatically transferred to other facilities. So, link (hyperlink) to related documents that are produced with specialized programs (like Dreamweaver) and can be made in an ordinary editor if the user knows the syntax which is defined as to create such documents.
Worm	A computer virus is programmed to spread from computer to computer over the Internet or other global networks. The program is multiplied hidden in your computer's memory, the most common consequence of infection is slowing down your computer or crash a computer system, where the worm does not infect other programs, and it does not destroy data directly.
Write cache enable / disable	Sometimes this term is found in the phrase 'write behind caching'. Today's devices in the computer as a microprocessor, hard drive, optical disk drives and the like, which require high throughput, have in the BIOS or the operating system to handle the possibility of adjusting data during read and write. Each of these devices has a fast SRAM buffer type in which they entered the required information, and some of the information about him on the assumption that they will consider one of the following information will be requested from the environment just read. In this way does not have to re-read the disc, but only the contents of the cache buffer and the reading of data is significantly accelerated. The problem can occur when when saving data to disk, the data is not saved immediately but later when they are more costly in the cache. If that moment comes to a halt work computer or power failure losing all the facilities that have not arrived enroll. This option to 'cache' is useful when saving off unless a quality server that has a 'smart' UPS device that is connected to it in a way that is mutually 'agreed ' that everything will be properly extinguish before the UPS batteries are 'leaking out'.
