`3l software interface that provides a way to access th
`MCIA sockets (slots) of a computer. Socket Services ide7
`is how many sockets are in your computer system
`and
`3cts the insertion or removal of a PC Card while the
`is powered on. Socket Services is part of the PCMpia
`reification and interfaces with Card Services
`vices is a software management interface that allows tho
`cation of system resources (such as memory and inter
`:s) automatically, once the Socket Services detects that a
`Card has been added. Card Services also releases thei
`lurces when the PC Card has been removed. Cara
`rices also provides you with an interface to higher IpJ
`rvare to load any needed hardware drivers,
`combination of PC Card hardware, Card Services soft.
`) and Socket Services software provides an almost “niun
`■play” capability in the portable computing environment
`3 the software has been installed, it is theoretically poss _
`o add and remove PC Cards without powering off the svs
`But this is theory. And in practice, it has worked onlv
`mittently for this writer. It doesn’t work for network cardc''

`mation into the portable computer’s memory, remove the

`3CMCIA has around 300 members, including manufac-
`" of semiconductors, connectors, peripherals and sys-
`3
`, as well as BIOS and software developers and related
`dries. Members include Intel, IBM, Toshiba, Lotus
`n and Fujitsu. The association is based in Sunnyvale!
`108-720-0107. It has an electronic bulletin board —^
`'’20-9388. Its standards are also recognized by the
`lese
`Electronic Industry Development Association
`A). The Association publishes a free book listing all the
`facturers making cards which comply to their standards
`e in buying PCMCIA cards: PCMCIA standards are stili
`formed and are thus not truly standards. Check that
`you buy work in your machine. The manufacturer
`d have tested it in your machine. Don’t assume compat-
`Check your socket and card services supports that
`!t may not. Use “enabler” software instead. Avoid PCM-
`ards with “pigtails.” They break. You lose them. Use
`/IA cards with an “X-JACK." You can plug directly into
`ICIA card with an X-JACK, or equivalent. If you have to
`card with a pigtail, buy a second pigtail, just in case.
`)4, the PCMCIA started calling its specs, PC Card,
`people said it was because many people claimed that
`JA stood for “People Can’t Memorize Computer
`ry Acronyms.”.
`latter part of 1995, the PCMCIA came out with a new
`cation called CardBus which is a 32-bit bus, as against
`:sent 16-bit cards. CardBus is an extension of the PCI
`his means that new CardBus will support 132 Mb|
`aster than the present 8 Mbps. See CardBus for a full

`p£N Personal Communications Network. A new type of wire-
`Ls telephone system that would use light, inexpensive
`handheld handsets and communicate via low-power anten
`nas. When it was originally conceived, PCN was primarily
`seen as an a city communications system, with far less range
`lhan cellular. Subscribers would be able to make and receive
`calls while they are traveling, as they can do today with cellu
`lar radio systems, but at a low price. Now PCN is seen as
`what Dr. Sorin Cohn of Northern Telecom calls an “enabler of
`unplanned growth." One idea for PCN is to locate a PCN cell
`site (transmitter/receiver) in a residential community. When
`someone wanted a new phone line, they’d simply drop down
`to their local phone store, pick up a PCN portable phone and,
`tjy the time, they got back home, their frequency would be
`•switched on” and they’d be “live.” The original plans for PCN
`never materialized fully. However, the concept has been
`Implemented in the forms of Personal Communications
`Service (PCS) and Wireless Local Loop (WLL). See also PCS,
`Personal Communications Network, Wireless Local Loop.

`2. Program Clock Reference: A timestamp that is inserted by
`the MPEG-2 encoder into the Transport Stream to aid the
`decoder in the recovering and tracking the encoder clock.
`PCR An ATM term. Peak Cell Rate: The Peak Cell Rate, in
`cells/sec, is the cell rate which the source may never exceed.
`PCS 1. the plural of PCs, i.e. PCc.
`2. Personal Communications Service. A new, lower powered,
`higher-frequency competitive technology to cellular. Whereas
`cellular typically operates in the 800-900 MHz range, PCS
`operates in the 1.5 to 1.8 Ghz range. The idea with PCS is that
`the phones are cheaper, have less range, are digital; the cells
`would be smaller and closer together and the airtime would be
`cheaper also. Several licenses have been awarded and sever-
`al systems have started in North America. The concept of PCS
`is evolving. It is not clear exactly where it will end up. So far,
`it looks like another cellular system with some digital mes
`saging on the phone’s larger screen, this is how the Federal
`Government awarded PCS licenses:

`Newton. When I added this definition in the late fall of 1992,
`sales of PDAs weren’t doing well and some wag in Silicon Valley
`called them Probably Disappointed Again. IBM prefers to call
`them Personal Communicators. General Magic prefers to called
`them PICs, Personal Intelligent Communicators.
