Task 4 Unit 5 (P2) & Unit 9 (P5)
Outline the purpose of networking tools.
Networking
tools
Directory
The purposes of networking tools are so that the network
manager can have complete control over the network, and this is done by using
such tools as a directory, account management, authenticity management, active
directory and DNS.
Account
The purpose of this tool is to allow the administrators of
the network to ensure that there is appropriate account management for groups
and users.
User Groups/ accounts
User groups are set up to make it easier to set up lots of
accounts, but it also provides a big advantage as if you need to allow a group
of users to have access to something it makes it easy to do so. Groups can be
set to only have rights to access certain areas such as files, directories,
printers or servers. User groups allow users to move from one computer to
another and keep their privileges.
Authenticity
When a request is made it usually needs to be authenticated
first, this isn’t only on user accounts but through internet ecommerce and
secure web pages where SSL is used
to insure that what is being sent is encrypted and from a secure site, this is
done by using a public and private key to insure that the page is as it says.
With user accounts a password and username are used to authenticate the user.
DNS
Domain name server is a server that is used to change domain
names into corresponding IP address. When the user searches for the domain name
the computer will check the cache to see if the use user has access the page
before and saved a location directory, if the directory isn’t there then it
will go to the DNS sever and find the page.
Files
File transfer
A networked system allows users to share files; this is
referred to as FTP. This allows users to share and receive files an example of software
for this is Filezilla. FTP can also be used to allow users to download files
without creating an account or password.
File Sharing
This type of file transfer is becoming more popular as it
offers increased speed and security as you are paying for the service that you
receive. The files that you download require a password and user account, you
can also download multiple files at once.
Application
services
Proxy server
A proxy is the middle man in trying to connect to the
specified server, this is done so that the user can be directed to the correct
place, and if the user has accessed the specified location before the proxy
would remember and direct it quicker to the correct place.
Storage space
Users can store there data in many different ways such as on
a cloud, on a HDD or Portable media. Each of these have their benefits and
flaws, for example if you store all of your data on a cloud, it is more prone
to getting attacked by a virus or hacker, however if you have it on a HDD it
could become corrupt and unusable.
VoIP
This is the protocol that allows users to send voice over
the internet; this converts the voice into a digital medium and sends the data
in packets to the recipient.
Telecommunication
IRC
This is a service that allows multiple people to connect
together and chat, this is done through an IRC client server, and all the data
is then sent in packets to this server and sent to everyone so that they all
get the information. This is a useful service as it allows people from all
around the world to connect together and talk.
Remote access
Remote access is when you can access a network from a
different location, this can be on mobile devices such as a smart phone or even
a laptop; however it can be quite a heavy program and could be quite demanding
on hardware, this means that a desktop would be the best choice for remote
accessing another system.
