`An application management suite from BMC that uses agents to report on software activities on all the

`agents detect events, collect information and notify system and network administrators to take corrective action.

`(2) (Personal Computer) Any laptop or desktop
`computer such as Windows machine or a Macintosh.
`(1) (Personal Computer) A stand-alone laptop or
`desktop computer running Windows (or DOS for earlier
`applications). PC hardware and operating systems are
`primarily governed by Intel and Microsoft respectively.
`The PC is the world's largest computer base.
`PCs are also widely used as clients and servers in a local
`area network (LAN). PC clients predominantly run under
`Windows, but PC servers (X86-based servers) run under
`Windows, NetWa.re or a variation of UNIX such as Linux
`or Unixware. PC servers may use Windows 95/98, but
`Windows NT and 2000 are more likely choices.
`Although there are literally thousands of PC vendors,
`from mom and pop shops to large mail order houses (Dell,
`Gateway, etc.) to the major computer companies (Compaq,
`HP, etc.), and of course IBM, still one of the world’s largest
`PC makers, all PCs use an Intel X86 or compatible CPU.
`After IBM introduced the PC in 1981, the first attempts at
`cloning it were mostly unsuccessful. Except for Cornpacfs first
`PC, from 1982 to 1985, there were a lot of ”almostcornpat‘1ble” PCs. However, as soon as the part of the operating system
`l<nown as the BIOS was successfully cloned and made commercially available, true Compatibles appeared in abundance.
`Before Windows 95, adding another peripheral device to a PC was often an exercise in trial and error. Modifying
`DOS's infamous configuration files (AU”DOEXBC.BAT and CONPIGSYS) caused many a user to give up. Windows 95.
`98 and 2000 added Plug and Play, which means for the most part, you can replace hard disks and display adapters, as
`well as acid a scanner, CD-ROM or other device without difficulty.

`The PC has become a commodity item,
`van one fraught with loopholes and inconsistencies.

`prototyping
`(1) Creating a demo ofa new systan. Prototyping is essential for clarifying inforrnationIEq1J‘l]_‘g]_-ne
`The design of a system (functionalspecs} must be finalized before the system can bebuilt. While analytically-onentergljm
`people may have a clear picture of requirements, others may not.
`Using fourth-generation languages, systems analysts and users can develop the new system together. Databases ca
`be created and manipulated while the user monitors the progress. Once users see tangible output on screen or papgr n
`they can figure out Whats missing or what the next question might be if this were a production system. Ifprototypkig
`is carefully done, the end result canbe a working system.
`Evenif the final system is reprogrammed in other languages for standardization or machine efficiency, prototyping
`has served to provide specifications for a working system rather than a theoretical one.

`proxy ‘See proxyserver.
`proxy cache
`A facility in aproxy server thatcaches incomingWeb pageson thehard disk. Ifthenextpage
`requested by a browser is already in the proxy cache, the page is retrieved locally instead of from the Internet. With
`proxy caches, the browsers mustbe configured to use the proxy server. See proxy server, reverse proxy cache, transparent
`cache and Web cache.
`'
`
`proxy server Also called a ”proxy” or "application level gateway,” it is an application that breaks the connection
`between sender and receiver. Allinput is forwarded out a different port, closing a straight pathbetweentwo networks
`and preventinga hacker from obtaininginternal addresses and details of a private network.
`Proxyservers are available for commonInternetservices; forexample, anHTTPproxyis usedforWebaccess, and
`an SMTPproxy is used for email. Proxies generally employ network address translation (NAT), which presents one
`organization-wide If‘ address to the Internet. It funnels all user requests to the Internet and fans responses back out to
`the appropriate users. Proxies may also cache Web pages, so that the next request can be obtained locally. Proxies are
`only one tool that can be used to build a firewall. See L/lN,firewall, proxy cache and SOCKS server.
`PR/SM (Processor Resource/Systerns Manager} Hardware circuits and microcode built into IBM Systemf390
`mainframes that support logical partitions (LPARS). LPARs allow the running of multiple system images on a single
`processor complex. Each such image has a full complement of CPUS (dedicated or shared), central storage, expanded
`storage and channels. ESCON and FlCON channels may be shared across images using the MIF feature. Pronounced
`“prism,” PR/SM was derived from VM, the IBM operating system that provides multiple system images in software.
`See LPAR, MI? and VM.
