etwork, local network. A local network links network components so that
they can exchange data and share resources. The physical range is restricted to a par-
ticular area (a site). A local network can be connected to other local networks or a wide-
area network (WAN) such as the Internet.

Network
A network is a group of devices connected in wired or wireless mode so that they can
share resources such as data and peripherals. A general distinction is made between
local networks (LANs) and wide-area networks (WANs).
Network adapter
The network adapter is the hardware device that creates the connection between a net-
work component and a local network. The connection can be wired or wireless. An Eth-
ernet network card is an example of a wired network adapter. A network adapter has a
unique address, the
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 proto-
col, 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.
