TFTP (Trivial File Transfer Protocol)  A version of the TCP/IP FTP protocol that has no directory or password capability.

Throughput  The amount of data moved successfully from one node to another in a given time period.

Trunking  Link Aggregation. Optimizes port usage by linking a group of ports together to form a single trunk (aggregated groups).

TX Rate  Transmission Rate.

UDP (User Data Protocol)  Communication protocol that transmits packets but does not guarantee their delivery.

Upgrade  To replace existing software or firmware with a newer version.

Upload  To transmit a file over a network.

URL (Uniform Resource Locator)  The address of a file located on the Internet.

VLAN (Virtual Local Area Networks)  Logical subgroups that constitute a Local Area Network (LAN). This is done in software rather than defining a hardware solution.

WAN (Wide Area Network)  Networks that cover a large geographical area.

Wildcard Mask  Specifies which IP address bits are used, and which bits are ignored. A wild card mask of 255.255.255.255 indicates that no bit is important. A wildcard of 0.0.0.0 indicates that all the bits are important.

For example, if the destination IP address is 149.36.184.198 and the wildcard mask is 255.36.184.00, the first two bits of the IP address are used, while the last two bits are ignored.
