You will find some advantages and some disadvantages of a network. Link them as in the example.
Example:
Linking some of the advantages and disadvantages of a network.

1. Although networks allow data to be shared, they permit viruses to spread quickly.
2. Users can share software on the server; however server failure means that no one can work.
3. Networks are more vulnerable to viruses; however it is easier to check for viruses.
4. Although maintenance is easier, networks require more expertise to maintain.
5. Networks are more complex to set up; however maintenance is easier.
6. Although access to the system can be controlled, networks are more vulnerable to viruses.
7. Hardware and software can be shared; however the whole network depends on the central server.

Disadvantages
1. Hardware and software can be shared.
2. Access to the system can be controlled.
3. Networks are more complex to set up.
4. Networks are more expensive to set up.
5. Maintenance is easier.
6. Networks are more vulnerable to viruses.
7. Users can communicate easily with each other.
8. It is easier to check for viruses.
9. The whole network depends on the central server.
10. It is easier to make backups.
11. Networks require more expertise to maintain.

Ways to minimize disadvantages of a network.
1. Employ well trained computing staff.
2. Use standard systems.
3. Try to negotiate bulk discounts.
4. Use thin clients instead of full computers.
5. Install an anti-virus program on the server.
6. Schedule frequent virus checks on the server.
7. Buy a good quality server.
8. Buy as powerful a server as you can afford.
9. Purchase a server with hot-swappable components.
10. Install a RAID system on the server.
11. Have a good training scheme for computing personnel
