·
Switch:
A switch is the central connection unit in a computer network. Every
device is connected directly or indirectly to the switch.
·
Router:
A router is sharing out data through the network. Mostly the router device
takes over other several features, such as Gateway-Server, DHCP-Server,
DNS-Server, Switch, WLAN-Access Point, Modem, UPNP-AV and NAS
via USB.
·
Access Point:
An access point is an extension of a router. If a router is incapable of
providing WLAN or its WLAN range is too limited, an access point can
be connected to one of the LAN ports of the router and extend its
functions.
·
Gateway:
A gateway connects computer or router to other networks (internet) and
controls these connections.
·
Modem:
A modem establishes a connection between LAN and WAN.
Nowadays all devices mentioned above are built in one device, which is
called
router
.
·
IP-Address:
The IP-Address identifies a device in the network. It is comparable to a
postal address. An IP address can only be used once within a network!
IPv4 (192.168.0.1) common standard
IPv6 (
2001:db8::1428:57ab
) future standard
·
DNS-Server:
A DNS-Server translates textual request to IP addresses and provides
simple communication to the internet.
(e.g. www.audionet.de is translated to "194.000.201.201")
·
Proxy:
Proxy-Server is usually used in lager network facilities to guarantee more
control and security to the network. Data transfer could be more efficient
and speeded up. Home networks do not need a proxy.
·
LAN (Local Area Network):
Localized network (home or company network)
·
Ethernet (cable):
Ethernet is a technology that specifies hardware and software for wired
data networks. An Ethernet connection offers a very good transmission
rate and is to be preferred.
