RJ-45
– A connector similar to a telephone connector that holds up to eight wires used for connecting
Ethernet devices.
Server
– Any computer whose function in a network is to provide user access to files, printing,
communications, and other services.
SMTP (Simple Mail Transfer Protocol)
– The standard e-mail protocol on the Internet. It is a TCP/IP
protocol that defines the message format and the message transfer agent (MTA), which stores and forwards
the mail.
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.
Port
– A pathway into and out of the computer or a network device such as a switch or router. For example,
the serial and parallel ports on a personal computer are external sockets for plugging in communications
lines, modems, and printers.
PPPoE (Point to Point Protocol over Ethernet)
– PPPoE is a method for the encapsulation of PPP packets
over Ethernet frames from the user to the ISP over the Internet. One reason PPPoE is preferred by ISPs is
because it provides authentication (username and password) in addition to data transport. A PPPoE session
can be initiated by either a client application residing on a PC, or by client firmware residing on a modem
or router.
Subnet Mask
– The method used for splitting IP networks into a series of subgroups, or subnets. The mask
is a binary pattern that is matched up with the IP address to turn part of the host ID address field into a field
for subnets.
TCP (Transmission Control Protocol)
– A method (protocol) used along with the IP (Internet Protocol)
to send data in the form of message units (datagram) between network devices over a LAN or WAN. While
IP takes care of handling the actual delivery of the data (routing), TCP takes care of keeping track of the
individual units of data (called packets) that a message is divided into for efficient delivery over the
network. TCP is known as a “connection oriented” protocol due to requiring the receiver of a packet to
return an acknowledgment of receipt to the sender of the packet resulting in transmission control.
TCP/IP (Transmission Control Protocol/Internet Protocol)
– The basic communication language or set
of protocols for communications over a network (developed specifically for the Internet). TCP/IP defines
a suite or group of protocols and not only TCP and IP.
Telnet
– A terminal emulation protocol commonly used on the Internet and TCP/IP-based networks. It
allows a user at a terminal or computer to log onto a remote device and run a program.
TFTP (Trivial File Transfer Protocol)
– A version of the TCP/IP FTP protocol that has no directory or
password capability.
Static IP Address
– A permanent IP address that is assigned to a node in a TCP/IP network.
