Difference between Client-Server and Peer-to-Peer Network - javatpoint
The main difference between peer-to-peer and client-server network, is that, in a peer-to-peer network, every node can demand for services and deliver services, but we if talk about client-server, in client-server, the client node can demand for services and the server node can reply with services.
The device which is in the network can communicate with each other. There are two types of network types one is peer-to-peer, and another is client-server. In a client-server network, many clients can connect to a server. The clients need services, and the server offers needed services. However, in a peer-to-peer network, we don't have any clients or servers. Instead, all nodes can act as clients or servers. In other words, every node can request services and deliver services.
A client-server network is also known as a network computing model. In this, we have clients and servers. A client includes a device or a program. Using this, end users can access the web. There are various examples of clients such as web browsers, laptops, desktops, smartphones, etc. A server includes a program or device that replies to the clients with the services. It offers databases, files, web pages, and shared resources based on their type.
In a client-server network, the client requests services from the server. The server reacts to client requests by rendering the necessary service after listening to their queries. A client-server network's key benefit is that it is safer because the server constantly controls access and security. Additionally, making backups is simpler. However, it is not very dependable because a server failure will impair the clients' ability to work. Additionally, the setup and maintenance costs are high.
The World Wide Web consortium is one of the most well-known examples of client-server architecture. In this, internet users, people like us, act as clients requesting information from the servers, and the servers reply by providing the precise information that was asked for.
The following are the advantages of client server network:
The following is the list of some important things which we need to know about the client-server network:
This model does not distinguish between clients and servers; each node acts as both a client and server. Every node in a peer-to-peer network has the ability to request and provide service. A node is also called a peer.
In a peer-to-peer network, a node joins the network and begins offering services, and then asks other nodes for services. Which node offers which service can be determined using one of two ways. The service that a node offers is registered with a centralised lookup service. Any node that needs a service consults the centralised lookup to determine which node offers particular facilities.
Then, communication occurs between the service-providing and service-requesting nodes. In the alternative technique, a node that needs particular services can broadcast a message to all other nodes that need the same service. The node with the necessary service responds to the node making the request by giving the desired service.
Peer-to-Peer networks have a number of benefits. It is simpler to keep up. To maintain the network, no specialist expertise is required. One machine is not the only thing that the network depends on. Additionally, the network setup doesn't call for a lot of hardware. Peer-to-peer networks, on the other hand, lack security significantly. Keeping an ordered file structure might be challenging as well. Additionally, users are responsible for managing their own backups.
One of the most well-known peer-to-peer networks is torrent. All computer in this kind of network is linked to the internet, allowing users to download resources shared by any one computer.
The local area network (LAN), which is typically preferred by small workplaces for the purpose of resource sharing, is another frequently used example of the peer-to-peer network.
The following are the advantages of peer-to-peer networks:
