TCP (Transport Control Protocol)
TCP is a connection-oriented network protocol for the transport layer (Layer
4) of the ISO/OSI model provided with relatively secure transmission
mechanisms.
TCP/IP Protocol Stack
The TCP/IP protocol stack denotes network protocols that enable communi-
cation between different networks and topologies.
Telnet
The Telnet protocol fulfils the function of a virtual terminal. It allows re-
mote access from the user's computer to other computer systems on the net-
work.
Traps
Traps are unsolicited messages, which are sent by an "agent" to a manage-
ment system, as soon as something unexpected and interesting for the man-
agement system happens. Traps are comparable to interrupts from hardware.
A well-known example of a trap message is the "Blue screen" with
Win95/98.
Twisted Pair
