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.
Subnet Mask
Subnet 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
with an incoming IP address to determine whether to accept or reject the packet.
TCP
(Transmission Control Protocol) is the transport protocol in TCP/IP that ensures messages
over the network are transmitted accurately and completely.
TCP/IP
TCP/IP (Transmission Control Protocol/Internet Protocol) is the main Internet communications
protocol. The TCP part ensures that data is completely sent and received at the other end.
Another part of the TCP/IP protocol set is UDP, which is used to send data when accuracy and
guaranteed packet delivery are not as important (for example, in realtime video and audio
transmission).
The IP component of TCP/IP provides data routability, meaning that data packets contain the
destination station and network addresses, enabling TCP/IP messages to be sent to multiple
networks within the LAN or in the WAN.
Telnet
Telnet is a terminal emulation protocol commonly used on the Internet and TCP- or IP-based
networks.
Telnet is used for connecting to remote devices and running programs. Telnet is an integral
component of the TCP/IP communications protocol.
UDP
(User Datagram Protocol) is a protocol within TCP/IP that is used to transport information
when accurate delivery isn't necessary (for example, real-time video and audio where packets
can be dumped as there is no time for retransmitting the data).
WAN
WAN (Wide Area Network) is a communications network that covers a wide geographic area
such as a country (contrasted with a LAN, which covers a small area such as a company
building).
