The Different Roles of Computers in a Client-Server and a Peer-to-Peer Network

Client-Server Network

In a client-server network, computers are classified as either clients or servers. A client is a computer that requests services or resources from a server. A server, on the other hand, is a computer that provides services or resources to clients.

The client-server network model is commonly used in organizations and businesses, where multiple computers need to access a central database or software application. The client computers send requests to the server, which processes the request and sends back the necessary information or resources.

The advantages of a client-server network include:

• Centralized management and control
• High level of security and control over access to resources
• Scalability, as more clients can be added without affecting the performance of the network

The disadvantages of a client-server network include:

• High implementation costs
• Dependency on the server, which can lead to downtime and decreased productivity if the server fails

Peer-to-Peer Network

In a peer-to-peer network, all computers are equal and can act as both clients and servers. Each computer has its own resources, such as files and printers, which can be accessed by other computers on the network.

Peer-to-peer networks are commonly used in small businesses and homes, where computers need to share files and resources with each other. Unlike client-server networks, there is no central server that manages access to resources.

The advantages of a peer-to-peer network include:

• Lower implementation costs
• Flexibility, as there is no dependency on a central server
• Easy to set up and manage

The disadvantages of a peer-to-peer network include:

• Less secure than client-server networks
• Not suitable for large organizations or businesses with high network traffic
• Performance can be affected if a large number of computers are connected to the network
