DNS
Domain Name System
DNS permits the assignment of IP addresses to computers or Domain name
s
that are
easier to remember. A DNS server must administer this information for each
LAN
with
an
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.
On the Internet, the assignment of domain names to IP addresses 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.

Domain name

Internet
. The
Domain name is mapped via the
DNS
service to the corresponding
IP address
.
DoS attack
Denial of Service
A DoS attack is a particular form of hacker attack directed at computers and networks
with a connection to the
Internet
. The aim is not so much to steal data but to paralyse
the computer or network so severely that the network resources are no longer available.
A typical hacker attack involves making a remote computer announce that it is acting for
the paralysed computer, for example, and receive the data meant for you.
DSL
Digital Subscriber Line
DSL can be run up to 8
Mbps
(ADSL) or 24
Mbps
(ADSL2+) over normal telephone lines.
A DSL connection is provided by an
Internet service provider
. It requires a DSL modem.
Dynamic IP address
A dynamic
IP address
is assigned to a network component automatically by the
DHCP
.
This means that the IP address of a network component can change with every login or
at certain intervals.
