SNTP
Simple Network Time Protocol. Used to synchronize the time of a terminal device with a

Subnet Mask
To discern the network part from the host part of an ->IP address, a device performs an
AND operation on the IP address and the network mask. The network classes A, B, and C
each have a subnet mask that demasks the relevant bits: 255.0.0.0 for Class A,
255.255.0.0 for Class B and 255.255.255.0 for Class C. In a Class C network, for instance,
254 IP addresses are available.
Switch
Network device that connects multiple network segments and terminal devices. The for-
warding of data packets is based on ->MAC Addresses: data targeted to a specific device
is directed to the switch port that device is attached to.
