Hosting Terminology >> P
- Packet Switching The method used to move data around on the Internet . In packet switching, all the data coming out of a machine is broken up into chunks, each chunk has the address of where it came from and where it is going. This enables chunks of data from many different sources to co-mingle on the same lines, and be sorted and directed to different routes by special machines along the way. This way many people can use the same lines at the same time. - Password A code used to gain access to a locked system. Good passwords contain letters and non-letters and are not simple combinations such as virtue7 . A good password might be "Hot$1-6" - Plug-in A (usually small) piece of software that adds features to a larger piece of software. Common examples are plug-ins for the Netscape® browser and web server . Adobe Photoshop® also uses plug-ins.The idea behind plug-in’s is that a small piece of software is loaded into memory by the larger program, adding a new feature, and that users need only install the few plug-ins that they need, out of a much larger pool of possibilities. Plug-ins are usually created by people other than the publishers of the software the plug-in works with. - POP POP stands for Post Office Protocol. This is a protocol used to retrieve e-mail from a mail server. Most e-mail applications use the POP protocol. The newest and most widely used version of POP email is POP3 email. You will see the term POP3 in most of the web hosting plans available today. - Port 3 meanings. First and most generally, a place where information goes into or out of a computer, or both. E.g. the serial port on a personal computer is where a modem would be connected. On the Internet port often refers to a number that is part of a URL , appearing after a colon (:) right after the domain name . Every service on an Internet server listens on a particular port number on that server. Most services have standard port numbers, e.g. Web servers normally listen on port 80. Services can also listen on non-standard ports, in which case the port number must be specified in a URL when accessing the server, so you might see a URL of the form: gopher://peg.cwis.uci.edu:7000/ shows a gopher server running on a non-standard port (the standard gopher port is 70). Finally, port also refers to translating a piece of software to bring it from one type of computer system to another, e.g. to translate a Windows program so that is will run on a Macintosh. - Portal Usually used as a marketing term to described a Web site that is or is intended to be the first place people see when using the Web. Typically a "Portal site" has a catalog of web sites, a search engine, or both. A Portal site may also offer email and other service to entice people to use that site as their main "point of entry" (hence "portal") to the Web. - Posting A single message entered into a network communications system. E.g. A single message posted to a newsgroup or message board. - PPP (Point to Point Protocol) Most well known as a protocol that allows a computer to use a regular telephone line and a modem to make TCP/IP connections and thus be really and truly on the Internet . - Primary Server The designation of "primary" means that this name server will be used first and will be relied upon before any of the other name servers. - PSTN (Public Switched Telephone Network) The regular old-fashioned telephone system. |
