The advantages of a client-server network include:

• security is created, managed and enforced

• backup of data is centralised

• many computers have access to centralised resources

• All options

A peer-to-peer network:

• usually links just two computers

• allows computers on the network to exchange files with each other

• is often used by people working in a large organisation

• is not vulnerable to hacking

A peer-to-peer network:

• uses a central file server loaded with the required applications

• requires only one anti-virus scanner for all computers in the network

• carries out automatic backup for all computers on the network

• is commonly found in a home or small office

Peer-to-peer networks:

• can only be used by up to ten people

• are less vulnerable to viruses than standalone computers

• are a type of client-server network

• are sometimes used for illegal file sharing of copyright material such as music and films

Which of the following is true of cloud computing?

• The network server is located on a satellite orbiting the earth

• CLOUD stands for Connected Links On Unlimited Devices

• Many users, separated by large distances, can run a program or application at the same time

• The cloud stores user data but not software

In cloud computing:

• Software and applications are commonly accessible via a web browser on any computer

• A single network server runs the cloud services

• Users have access to unlimited free storage of data

• There is no danger of sensitive data being hacked

Cloud computing is used for:

• social networking

• online data storage

• online data storage

• All options
