Regular postal service or snail mail.
Piece Of Data (rather than a programming instruction).
Pentium. The Intel high-performance microprocessor introduced in 1993, also called 586 or 80586. It is about twice as fast as the 486.
The Pentium Pro. Successor to the Pentium microprocessor; also called 686 or 80686. The P6 has internal RISC architecture and a CISC-RISC translator. It is faster than the Pentium for 32-bit software but slower for 16-bit software.
p7zip is a port of the command line version of the 7-Zip file archiver—famous for its introduction of the high-compression 7z format—to POSIX-conforming operating systems, such as Unix, Linux, Windows NT (or greater version) and Mac OS X. It is free software, available under the LGPL free software license.
A RISC chip used in HP minicomputers and workstations.
|PA: Power Amplifier|
Power Amplifier (PA) is a device for taking a low or intermediate-level signal and significantly boosting its power level. A power amplifier is usually the final stage of amplification in a transmitter.
Private Automatic Branch Exchange. A private automatic telephone exchange that allows calls within the exchange and also calls to and from the public telephone network.
To store data in compressed form in such a way that the data can be restored to its original form (unpacked).
An application program or collection of programs developed to meet the needs of a variety of users, rather than custom designed for a specific user or company. Packaged software is sold to the general public.
Packaged software refers to a commercial application program or collection of programs developed to meet the needs of a variety of users, rather than custom designed for a specific user or company. Packaged software is normally put on a CD (or disks), packaged in a box and sold to the general public.
|Packard Bell Electronics, Inc.|
A leading U.S. computer vendor based in Sacramento, California. Packard Bell originally started in 1926 as a radio manufacturing company, and now markets complete computer systems in major retail chains.
|packed decimal format|
A means of storage in which each byte holds two decimal digits (four bits per digit), except the rightmost byte which contains one digit and the sign (+ or -). See unpacked decimal format.
A unit of data formatted for transmission on a network. Data is broken up into packets for sending over a packet switching network. Each packet has a header containing its source and destination, a block of data content, and an error-checking code. All the data packets related to a message may not take the same route to get to their destination; they are reassembled once they have arrived.
Also referred to as a datagram, a packet is the basic unit of information carried across a network. For easy and correct transmission, data within a packet contains error-checking information, and source and destination addresses in addition to the message to be delivered.
Packet, maybe called datagram in some cases, is a unit of a message transmitted over a packet-switching network. Data is broken up into packets for sending over a packet switching network. Each packet has a header containing its source and destination, a block of data content, and an error-checking code. All the data packets related to a message may not take the same route to get to their destination; they are reassembled once they have arrived.
|packet assembler / disassembler|
(PAD). A hardware device that makes it possible for a data terminal not set up for packet switching to use a packet switching network. It assembles data into packets for transmission, and disassembles the packets on arrival so they can be used.
Packet Buffer refers to the memory which is utilized to store data packets awaiting transmission. This memory is either on the Network Interface Card or the computer memory.
Packet buffer is the memory space reserved for storing a packet awaiting transmission or for storing a received packet. Packet buffer is set aside specifically for either storing a packet that is awaiting transmission over a network or storing a packet that has been received over a network. The memory space is either located in the network interface card or in the computer that holds the card.
Packet transmission of data via cellular network.
Local area network software that divides data into packets for sending on the network, and reassembles the data into its original form when it arrives at its destination.
|packet internet groper|
(PING). A program used to test whether a particular network destination is online, by sending an Internet control message protocol (ICMP) echo request and waiting for a response. (Also called packet internet gopher).
On a packet-switched network, the time it takes to transmit the extra bytes of formatting information included with each packet, and to assemble and disassemble the packets. The total transmission time includes packet overhead as well as the time it takes to transmit the raw data.
