Networks and
Communication
Part C
- Client-Server Network
- The clients are linked to the server and the server handles;
File Storage, Backup, Application Sharing, Printer
Management.
- They are connected via a communication device.
- Passwords are needed in
order to gain access to the
resources such as files and
printers.
- These users get a certain amount of storage
space, the printers, files (these can be locked
for certain users) and software on the server
- The antivirus software is managed centrally which means
that it is safer, although it does need specialist staff
- The clients are linked to the server and the server handles;
File Storage, Backup, Application Sharing, Printer
Management.
- Peer-to-peer Networks
- A peer to peer network does not have a central server
- Each of the computers have their own
software installed on the computer
- It is easier to set up and maintain for a user that does not have
specialist help. This is why it is commonly found in homes and
small offices.
- In a peer to peer network there is no leader that acts as a
server as there is no server role.
- A peer to peer network does not have a central server
- Advantage and Disadvantage
- Advantage for Client-Based
- Backups are made centrally so
the users don't have to think
about them
- Antivirus software is
taken care of centrally
- There is more processing
power available to the client as
the network processing is
done centrally
- File sharing is available, as
is sharing of resources such
as printers and software
- Backups are made centrally so
the users don't have to think
about them
- Disadvantage for Client-Based
- If the server fails then all of the
files are inaccessible
- A specialist network manager is a necessity
- There can be lots of network
traffic if lots of applications are
run from the server
- The hardware is expensive
- If the server fails then all of the
files are inaccessible
- Advantage for Peer-to-Peer
- There is no reliance on a server, only
the resources on a particular
computer are lost
- This type of network can
be set up by a
non-specialist
- No very expensive
hardware neeeded
- There is no reliance on a server, only
the resources on a particular
computer are lost
- Disadvantages for Peer-to-Peer
- The responsibility of backups and
maintaining antivirus software is on the
user
- Processing is done
by each client
- Software needs to be installed on
each computer
- The responsibility of backups and
maintaining antivirus software is on the
user
- Advantage for Client-Based
