Pros & Cons of Client-Server Model

Computer Science: OCR GCSE, topic 1.3.6

Pros of the Client-Server Model

The client-server model works well for almost all network communications, but it isn't always the best way.

Centralised server

Centralised server

  • User's files can be stored centrally so it is easy to access them from any networked computer.
  • Team members can easily share files.
Monitoring

Monitoring

  • Client machines can be monitored centrally.
  • This means that administrators can make sure that nobody breaks the terms and conditions of the network.
  • User accounts can be managed centrally. For example, an administrator could:
  • Retrieve lost files.
  • Recover lost passwords.
Security

Security

  • Software and security updates can be managed centrally and applied to all computers.
  • This saves time.

Cons of the Client-Server Model

The client-server model works well for almost all network communications, but it isn't always the best way.

Risk of downtime

Risk of downtime

  • If the central server fails, then the whole of the network would not be able to function.
High cost

High cost

  • Server hardware is usually very expensive.
Security

Security

  • Servers are often targeted in cyber attacks such as:
  • Ransomware attacks.
  • Denial of service attacks.

  • What central management could a network administrator perform?

  • Why might a network administrator want to apply security updates using a client-server model?

  • Which of these events could break an entire client-server network?
