Client-server model

Clients send requests to the server for data or resources. The server then processes the request and responds.

What does a server store?

- User profiles - Passwords - Access information

Advantages of client-server model

- Easier to keep track of files as they are stored centrally. - Easier to perform backups as they are managed from a single location. - Easier to manage network security. - Servers can process many requests at once.

Advantage - How are client-server networks scalable?

You can easily add new devices (clients) or upgrade the server without disrupting the entire network.

Disadvantages of client-server model

- Expensive to set up - Requires IT specialists to maintain the network and server - If the central server goes down, the whole network does down with it + clients lose their resources. - If too many clients are accessing the server at once, it may become overloaded.
