Term Definition
Subnet Mask
Used to mask all or part of an IP address used in a subnet address. Switch Filters and
forwards packets between LAN segments. Switches support any packet protocol type.
T
TCP/IP
Transmissions Control Protocol. Enables two hosts to communicate and exchange data
streams. TCP guarantees packet delivery, and guarantees packets are transmitted and
received in the order the are sent.
Telnet
Terminal Emulation Protocol. Enables system users to log in and use resources on
remote networks.
TFTP
Trivial File Transfer Protocol. Uses User Data Protocol (UDP) without security features to
transfer files.
Trap A message sent by the SNMP that indicates that system events have occurred.
Trunking
Link Aggregation. Optimizes port usage by linking a group of ports together to form a
single trunk (aggregated groups).
U
UDP
User Data Protocol. Communication protocol that transmits packets but does not
guarantee their delivery.
Unicast A form a routing that transmits one packet to one user.
V
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.
VSDL
Very High Bit Rate DSL. An asymmetric DSL version used at the fiber optic junction point
final drop to nearby customers.
W
WAN
Wide Area Networks. 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.
