`
`upstream
`
`The "line interactive UPS" is a hybrid of the online and standby units. Like the standby, ii does not constantly draw
`from the battery, but it switches to battery faster when required. In addition, the line interactive 1.mH does not use the
`battery when low voltage is encountered. It uses extra power from the AC source to make up the difference in voltage.
`A surge protector filters out surges and spikes, and a voltage regulator maintains uruform voltage during a brownout,
`but a UPS keeps a computer running when there is no electrical power. UPS systems typically provide surge suppression
`and may also provide voltage regulation.
`
`UPS-Now More Than Ever
`In order to improve performance, computers are increasingly using write-back caches,
`which means that updated data intended for the disk is temporarily stored in RAM, If a power failure occurs, there is
`more of a chance that new data will be lost; thus, UPS systems are becoming important for all computers.
`
`upstream See downstream.
`
`uptime The time during which a system is working without failure. Contrast with downtime. Set: mmi/11bility.
`
`upward compatible Also called "forward compatible." Refers to hardware or software that is compatible with
`succeeding versions. Contrast with downward compatible.
`
`URI
`(Uniform Resource Identifier) The addressing technology from which URLs are created. Technically, URLs
`such as HTTP: // and FTP:// are specific subsets of URJs.
`
`URL
`(Uniform Resource Locator) The address that defines the route to a file on the Web or any other Internet facility.
`URLs are typed into the browser to access Web pages, and URLs are embedded within the pages themselves to provide
`the hypertext links to other pages.
`The URL contains the protocol prefix, port number, domain name, subdirectory names and file name. Port addresses
`are generally defaults and are rarely specified. To access a home page on a Web site, only the protocol and domain name
`are required. For example,
`
`http://www .computerlanguage.com
`
`retrieves the home page at The Computer Language Company's Web site. The "http" is the Web protocol, and
`www.computerlanguage.com is the domain name.
`
`If the page is stored in another directory, or if a page other than the home page is required, slashes are used to separate
`the names. For example, http://wi.vw.computerlanguage.com/order.html points to the order page.
`If a required page is stored in a subdirectory, its name is separated by a slash. Like path names in 00S and
`Windows, subdirectories can be several levels deep. For example, the components of the following hypothetical URL
`are described here:
`
`http:/ / www.abc.com/clothes/ shirts/formal.html
`
`http:
`II
`www.abc.com/
`clothes/
`shirts/
`formal . html
