If the CEO dispatches his data exclusively via AS2 (to respond to the casual EDI) instead of via FTP or OFTP, uses AES or DES and shares his signature based upon PGP with his business partners - then maybe the time is right to have a look at our i-effect® lexicon.A | B | C | D | E | F | G | H | I | J | K | L | M | N | O | P | Q | R | S | T | U | V | W | X | Y | Z
PCL
Printer Command Language, more commonly referred to as PCL, was developed by HP as a printer protocol and has become a de facto industry standard. Originally developed for early inkjet printers in 1984, PCL has been released in varying levels for thermal, matrix printer, and page printers. HP-GL and PJL are supported by later versions of PCL.
Portable Document Format (PDF) is a file format created by Adobe Systems in 1993 for document exchange. PDF is used for representing two-dimensional documents in a manner independent of the application software, hardware, and operating system.
PDF Direct
PDF Direct is a label used by HP for their printers having a PDF processor, i.e. an application integrated into the printer that permits the conversion of a PDF document into a printable graphic.
PDF/A
PDF/A is a file format for the long-term archiving of electronic documents. It is based on the PDF Reference Version 1.4 from Adobe Systems Inc. (implemented in Adobe Acrobat 5 and latest versions) and is defined by ISO 19005-1:2005, an ISO Standard that was published on October 1, 2005: * Document Management - Electronic document file format for long term preservation - Part 1: Use of PDF 1.4 (PDF/A-1) PDF/A is in fact a subset of PDF, obtained by leaving out PDF features not suited to long-term archiving.
PGP
Pretty Good Privacy (PGP) is a computer program which provides cryptographic privacy and authentication. The first released version of PGP, by designer and developer Phil Zimmermann, became available in 1991. Subsequent versions have been developed by Zimmermann and others.
While PGP can encrypt the content of any data (e.g., any binary file or message text), it is most commonly used for e-mail and internet faxing, which have no built-in security as originally implemented. PGP and S/MIME are two (incompatible) official email security systems which are currently NIST specified standards.
PKI
In cryptography, a public key infrastructure (PKI) is an arrangement that provides for trusted third party vetting of, and vouching for, user identities. It also allows binding of public keys to users. This is usually carried out by software at a central location together with other coordinated software at distributed locations. The public keys are typically in certificates.
PKI arrangements enable users to be authenticated to each other, and to use the information in identity certificates (i.e., each other´s public keys) to encrypt and decrypt messages travelling to and fro. In general, a PKI consists of client software, server software such as a certificate authority, hardware (e.g., smart cards) and operational procedures. A user may digitally sign messages using his private key, and another user can check that signature (using the public key contained in that user´s certificate issued by a certificate authority within the PKI). This enables two (or more) communicating parties to establish confidentiality, message integrity and user authentication without having to exchange any secret information in advance.
POP3
In computing, local e-mail clients use the Post Office Protocol version 3 (POP3), an application-layer Internet standard protocol, to retrieve e-mail from a remote server over a TCP/IP connection. Nearly all subscribers to individual Internet service provider e-mail accounts access their e-mail with client software that uses POP3.
POWER6
The POWER6 is a microprocessor developed by IBM that implemented the Power ISA v.2.03. When it became available in systems in 2007, it succeeded the POWER5+ as IBM´s flagship Power microprocessor.
PowerVM
PowerVM, formerly known as Advanced Power Virtualization (APV), is a chargeable feature of IBM POWER5 and POWER6 servers and is required for support of micro-partitions and other advanced features.
PTF
Program temporary fix (PTF) is the standard IBM locution to designate single bug fix, or group of fixes, distributed in a form ready to install for customers. Often explained in tongue-in-cheek manner as permanent temporary fix or more practically probably this fixes.
These repairs to IBM software are often in response to APARs (Authorised Program Analysis Reports) submitted by customers and others and acted on by IBM. It is generally expected by the customer that the problem would be fully corrected in the next release (version) of the relevant product.
Push-Technologie
Push technology, also called server push or webcasting, describes an internet-based content delivery system where information is delivered from a central server to a client computer based upon a predefined set of request parameters outlined by the client computer. Illustratively a client computer such as a desktop home user would subscribe to various information topics provided by a content provider and as that content is created by the content provider, such information is "pushed" or delivered across the internet to the desktop home user and displayed on that users computer. Push Technology differs from normal internet technology, which is based on Pull Technology where a user has to request a Web Site through an internet browser.
The original push technology was in fact E-mail, as unrequested messages are delivered from the server to the client. Another type of Push technology gained popularity in the 1990s using PointCast software. It got a lot of media attention and both Netscape and Microsoft integrated it heavily into their software at the height of the browser wars. However, most people didn´t find push technology useful, and it later faded into more obscure corners of software packages.
