Pager- In a virtual memory computer, paging is the transfer of program segments (pages) into and out of memory. Although paging is the primary mechanism for virtual memory, excessive paging is not desired. For more information go to our home page.

Passwords- A secret word or code used to serve as a security measure against unauthorized access to data. It is normally managed by the operating system or DBMS. However, the computer can only verify the legitimacy of the password, not the legitimacy of the user. For more information on passwords go to our home page.

Pin Outs- The description and purpose of each pin in a multi-line connector. For more information go to our home page.

Ping- (Packet INternet Groper) An Internet utility used to determine whether a particular IP address is online. It is used to test and debug a network by sending out a packet and waiting for a response. For information go to our software page.

Ping Time- Ping Time uses a Cisco Router to record ping Round Trip Times from the router to any IP address. The minimum, average and maximum response time are recorded over several pings by the router and the results retrieved. For more information go to our Administrative Tools page.

PPP- (Point-to-Point Protocol) The communications protocol used to dial up the Internet over a serial link, such as a POTS or ISDN line. Developed by the Internet Engineering Task Force in 1994, it superseded the SLIP protocol. PPP establishes the session between the user's computer and the ISP using the Link Control Protocol (LCP), which also handles authentication (PAP, CHAP, etc.), compression and encryption. PPP encapsulates protocols in specialized Network Control Protocol packets and supports other high-level protocols such as IPX, AppleTalk and DECnet. For example, IPCP (IP over PPP) encapsulates TCP/IP packets for the Internet, and IPXCP (IPX over PPP) encapsulates IPX packets for NetWare networks. PPP can multiplex different protocols over the same circuit. For more information go to our home page.

Print Server- A computer in a network that controls one or more printers. It is either part of the network operating system or an add-on utility that stores the print-image output from users' machines and feeds it to the printer one job at a time. The computer and its printers are known as a "print server" or a file server with "print services." For more information go to home page.
