Network protocol
The network protocol is the standard via which different PCs exchange data in a net-
work. A connection can only be established between PCs in a network if they all use the
same protocol. The
network protocol is the most extensive network protocol,
which is also used for connections to the Internet. This must be set up on each PC from
which a network connection is to be established.
Protocol
A protocol describes the agreements for communicating on a network. It contains rules
for opening, administering and closing a connection, as well as about data formats,
time frames and handling possible errors. Communications between two applications
require different protocols at various levels, e.g. the
