The Internet is a data network with millions of members. A number of protocols are
used to exchange data, summarized under the term TCP/IP.
All devices connected to the Internet can be identified via IP address. The DNS
server assigns domain names to IP addresses.

see ISP.
The IP protocol is a TCP/IP protocol. It is responsible for addressing devices on a
network based on IP addresses and transmitting data packages from sender to
Receiver. The IP protocol determines the order and network connection used to
send data packages (routing).
The transmission control protocol TCP reassembles the data packages in the right
order at the Receiver.
The IP address is a unique address of a network device on the network based on
TCP/IP protocols. The IP address consists of four sections, separated by a dot
(192.168.1.1).
The IP address comprises the network number and the computer number
(number of the network device). Depending on the subnet mask, one, two or three
portions form the network or computer number.
IP addresses can be assigned automatically or manually. On the Internet, domain
names are used rather than IP addresses. The DNS server assigns domain
names to IP addresses.
IP address pool defined at the router (IP address range) the DHCP server can be
used to assign dynamic IP addresses.
A local network (size: large building, building sites) is a number of interconnected
network devices. In LANs, data is exchanged and resources are used jointly. A
LAN can be connected to other networks such as WAN or Internet.
see LAN.
The MAC address allows for worldwide identification of a network adapter (net-
work card). It consist of hexadecimal numbers, grouped in six portions at 2x4 bit
each, thus 48 bit, e.g. 00-55-96-5D-00-2C. The MAC address is assigned by the
network adapter manufacturer and cannot be changed.
Million bits per second indicates the transmission rate in a network.
