TLS
Transport Layer Security - protocol for the encryption and secure trans-
mission of data on the Internet. TLS is often used to protect http connec-
tions, e. g. for commercial transactions (https).
T-Net Functions
Functions available on the analogue T-Net in Germany. There are analogue
comfort telephones with pre-defined function keys or menus for T-Net
functions such as callback on busy, call forwarding, toggling between
conversations or conference calling.
U
UDP
User Datagram Protocol) - protocoll used to send data packets over non-
secure communication lines without a connection. This means that
successful transmission is dependent on the application and is therefore not
always guaranteed. UDP itself does not verify whether data has been trans-
mitted successfully. When a UDP packet is sent, the sender cannot assume
that the packet will indeed arrive at the recipient. This particular protocol
needs only a small amount of additional information, and results in a better
data throughput rate in a well-functioning network, e. g., on a LAN. UDP is
used by DNS servers, for example.
