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.
