Value specified to indicate how much of a internet address should be used to indentify machines on a local network or subnet.

Protocol that uses a standard 40 Octet (byte) header.

Service that converts a computer's hardware level local network identifer to a hardware independent internet address.

Specific Internet protocol that uses a four octet value to address/identify individual systems on the internet.

System that acts as an interface between a local network and the internet as a whole or an organization's larger network backbone.

Local network architecture that uses a technique to allow all systems on the network a fair share of time on the network. It does this by passing a special packet from system to system granting access to the local network for a time.

Internet address protocol that provides an 128 bit address that is classless, upper 64 bit used for domain specification and lower 64 bits to address systems on a particular domain.

Service that allows users to subsitute text name, e.g www.cs.niu.edu for the numeric internet address actually used to communicate across the Internet.

LAN protocol that allows any system on the network to communicate at will as long as another system is not already communicating. Communicating system must continue monitoring to avoid possible communication from other systems.

LAN protocol that allows any system on the network to communicate at will as long as another system is not already communicating. Communincating system initially sends a small frame reserving the bandwith for a specified time thus avoiding packet collision.

LAN architecture that uses radio waves to transmit packets.

Service on local system keeps track of discovered IPs for DNS names used.

Network packet sent only as part of a negotiated connection with the remote system.
