Access point
An Access point is the centre of a
linked network components and regulates the data traffic within the network. The
access point also serves as an interface to other networks, e. g. via a router to the
net.
Client
A Client is an application that requests a service from a Server. For example, an http Cli-
ent on a PC in a local network requests data, i.e. Web pages from an HTTP Server on the
Internet. Frequently the network component (e. g. the PC) on which the Client applica-
tion is running is also called a Client.

easier to remember. A DNS server must administer this information for each

Internet
connection. As soon as a page on the Internet is called up, the browser
obtains the corresponding IP address from the DNS Server so that it can establish the
connection.
The assignment of domain names to IP addresses on the Internet follows a hierarchical
system. A local PC only knows the address of the local Name Server. This in turn knows
all the addresses of the PCs in the local network and the superordinated Name Servers,
which again know addresses and the next superordinated Name Servers.
