PCM
PCM (Pulse Code Modulation) is a technique for converting analog audio
signals into digital form for transmission.
PING
Packet Internet Groper, a utility used to determine whether a specific IP
address is accessible. It functions by sending a packet to the specified
address and waits for a reply. It is primarily used to troubleshoot Internet
connections.
PPPoE
Point-to-Point Protocol over Ethernet. PPPoE is a specification for
connecting the users on an Ethernet to the Internet through a common
broadband medium, such as DSL or cable modem. All the users over the
Ethernet share a common connection.
Protocol
Communication on the network is governed by sets of rules called
protocols. Protocols provide the guidelines devices use to communicate
with each other, and thus they have different functions. Some protocols are
responsible for formatting and presenting and presenting data that will be
transferred from file server memory to the file server’s net work adapter
Others are responsible for filtering information between networks and
forwarding data to its destination. Still other protocols dictate how data is
transferred across the medium, and how servers respond to workstation
requests and vice versa. Common network protocols responsible for the
presentation and formatting of data for a network operating system are the
Internetwork Packet Exchange (IPX) protocol or the Internet Protocol (IP).
Protocols that dictate the format of data for transferors the medium include
token-passing and Carrier Sense Multiple Access with Collision Detection
(CSMA/CD), implemented as token-ring, ARCNET, FDDI, or Ethernet. The
Router Information Protocol (RIP),a part of the Transmission Control
Protocol/Internet Protocol (TCP/IP) suite, forwards packets from one
network to another using the same network protocol.
R
RJ-45
RJ-45 connector is used for Ethernet cable connections.
Router
A router is the network software or hardware entity charged with routing
packets between networks.
