Router
- A hardware device that connects two separately functional networks that use same
or different protocols. Routers look at the destination addresses on the packets passing
through them and then decide the best route to send them on.
SDSL
- Symmetrical DSL — A DSL technology that provides the same amount of
bandwidth (up to 1.5 Megabits) both upstream and downstream.
Segment
- A physical or logical portion of a network. An Ethernet segment does not cross
any bridge or router, but includes everything up to a bridge or router connection.
Service Provider

ISP
.
SNMP
- Simple Network Management Protocol — A protocol used commonly for
managing network devices remotely.
Static IP address
- A permanent IP address that is assigned to a node in a TCP/IP network.
Servers and routers are usually assigned static IP addresses, while client stations are
often assigned dynamic IP addresses from a DHCP server each time they come online.
For users connected to the Internet via cable modems and DSL either in the office or at
home using long term (static) IP addresses, it makes them more vulnerable to hacker
attacks than IP addresses that are dynamically assigned. See dynamic IP address, IP
address and DHCP.
Subnet address
- The portion of IP address that identifies the subnet.
Subnet Mask
- A 32-bit address string that is used to identify the bits of an IP address that
are used for the subnet address. A Subnet Mask is usually represented in dotted-
decimal notation, for example, 255.255.255.0.
Subnet or Subnetwork
- Any network that is a part of a larger IP network and is identified
by a subnet address.
Switch
- A device used for connecting nodes in a star topology, that is all nodes are
connected to a central switch. By monitoring packets, a switch learns which devices are
connected to its ports and then sends a packet to the appropriate port only.
TCP/IP
- Transmission Control Protocol/Internet Protocol. A suite of communication
protocols that are used by computers or networking devices on the Internet so that they
can communicate with each other. TCP/IP uses several protocols, the two main being
TCP and IP.
