A proxy is a server used by network devices for Internet traffic. All requests are
sent via the proxy server.
The web server does not support HTTPS (Hyper Text Transfer Protocol Secure).
A hub in a star-topology network connects various network devices by receiving all
data from one device and forwarding it to other devices.
See HTTPS
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 IP
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
recipient. 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 recipient.
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.
The ISP provides the connection to the Internet via DSL or cable TV (at a fee).
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.
