P5- Describe typical services provided by
networks
Describe typical services provided by networks.

Directory services: used for e.g.

Account management
Account management is important for many networks and the users connected to it as it
allows for certain powers for each user. Account management has the power to edit the user
and the type of account it is, adding and removing users of the network and granting
accessing to specific areas but normally this is strictly monitored. Many important
organisations use this that manage a large number of users so for example when a new
person joins the organisation a new user is created using the account management and
their policies are set and the same rule applies when a person leaves the organisation.
Account management can also chance powers for certain users for example a higher level
person in the business which gained promotion can get higher access to be a computer
administrator and allow for local machine editing.

Authentication management
Authentication management is a service normally that is used for form ID and in operating
system users. All the different users connected will have different authorities such as some
can access the network and use resources of the public network and access the printer
connected to the network and authentication management takes care of this by verifying
specific things about the user. There are many authentication management methods such
as Passwords (Depending on the complexity of the password it will be verified using
different methods), Encrypted Certificates (often certificates are provided for some level of
authentication), Smart Card (which can be scanned and verify

Active directory
Active directory is another type of directory service made by Microsoft Corporation. This can
be used in small or big networks. This kind of directory can store entire objects and verify
the directory to authenticate it. However active directory is only installed in special network
operating systems as this is a special feature to manage networks. For example it can verify
all users and computers in the windows domain network and enforce security policies, so
when a person logins into a computer and submit the password active directory will check
whether the password was correct in the first place and also it will decide whether the user
is an administrator, guest or a normal user. However it also use in telephones and telephone
directory. For example it will sort, look up and request information based the original
request.

DNS
DNS Stands for domain name server and is very important for the internet and every
network connected. DNS Translates domain names that are normally in alphabetic so they
are easier for humans to remember and then they are translated into IP Addresses. For
example www.google.co.uk can be translated into 192.165.261.3. DNS Runs special
purpose network software to find each of the addresses over the internet. For example your
web browser acts as a DNS Client that issues a request to the DNS Server normally on a
database so navigation is made easier, there are many DNS Servers all with different
hierarchy and if one of the lower ones don’t find it the next higher one is needed and finally
one the request is fulfilled it will flow back from the chain of DNS Servers to the client so
they can get the webpage they requested for. Of course DNS Servers are fast and
everything happens in a blink of an eye otherwise it will cause further delay. Furthermore
