PING
Ping (Packet INternet Groper) is a utility used to find out if a particular IP address is present online, and is
usually used by networks for debugging.
PORT
Ports are the communications pathways in and out of computers and network devices (routers and
switches). Most PCs have serial and parallel ports, which are external sockets for connecting devices
such as printers, modems, and mice. All network adapters use ports to connect to the LAN. Ports are
typically numbered.
PPPOE
PPPoE (Point-to-Point Protocol Over Ethernet) is used for running PPP protocol (normally used for
dial-up Internet connections) over an Ethernet.
PREAMBLE
Preamble refers to the length of a CRC (Cyclic Redundancy Check) block that monitors communications
between roaming wireless enabled devices and access points.
PROTOCOL
A protocol is a rule that governs the communication of data.
RIP
RIP (Routing Information Protocol) is a routing protocol that is integrated in the TCP/IP protocol. RIP finds
a route that is based on the smallest number of hops between the source of a packet and its destination.
RTS
RTS (Request To Send) is a signal sent from the transmitting station to the receiving station requesting
permission to transmit data.
SERVER
Servers are typically powerful and fast machines that store programs and data. The programs and data
are shared by client machines (workstations) on the network.
SMTP
SMTP (Simple Mail Transfer Protocol) is the standard Internet e-mail protocol. SMTP is a TCP/IP
protocol defining message format and includes a message transfer agent that stores and forwards mail.
SNMP
SNMP (Simple Network Management Protocol) is a widely used network monitoring and control protocol.
SNMP hardware or software components transmit network device activity data to the workstation used to
oversee the network.
SSID
SSID (Service Set Identifier) is a security measure used in WLANs. The SSID is a unique identifier
attached to packets sent over WLANs. This identifier emulates a password when a wireless device
attempts communication on the WLAN. Because an SSID distinguishes WLANS from each other, access
points and wireless devices trying to connect to a WLAN must use the same SSID.
SUBNET MASK
Subnet Masks (SUBNETwork masks) are used by IP protocol to direct messages into a specified network
segment (i.e., subnet). A subnet mask is stored in the client machine, server or router and is compared
