There are different models for connecting computers over a network. Two of the most common are:. This type of network separates computers into one of two classifications - servers and clients.


Client-server denotes a relationship between cooperating programs in an application, composed of clients initiating requests for services and servers providing that function or service. The client-server model, or client-server architecture, is a distributed application framework dividing tasks between servers and clients, which either reside in the same system or communicate through a computer network or the Internet. The client relies on sending a request to another program in order to access a service made available by a server. The server runs one or more programs that share resources with and distribute work among clients. The client server relationship communicates in a request—response messaging pattern and must adhere to a common communications protocol, which formally defines the rules, language, and dialog patterns to be used. TCP protocol maintains a connection until the client and server have completed the message exchange. TCP protocol determines the best way to distribute application data into packets that networks can deliver, transfers packets to and receives packets from the network, and manages flow control and retransmission of dropped or garbled packets.

A client server network is a specific type of online network comprised of a single central computer acting as a server that directs multiple other computers, which are referred to as the clients. By accessing the server, clients are then able to reach shared files and information saved on the serving computer. Examples of computer applications that use the client-server model are Email, network printing and the World Wide Web. In a client-server model, whether a computer is a client, server or both, is determined by the nature of the application that requires the service functions. For example, a single computer can run web server and file server software at the same time to serve different data to clients making different kinds of request. Client software can also communicate with server software within the same computer.

Comparison between client-server , peer-to-peer and hybrid architectures for MMOGs

The ability to share information and resources is a vital part of information technology. A peer-to-peer P2P network could help your business run more efficiently by improving connectivity and access to shared resources. A peer-to-peer network is an IT infrastructure in which two or more computer systems connect in order to share resources. Workplaces may set up this type of network by physically connecting computers into a linked system or creating a virtual network. You can also set up computers to be the clients and servers of their network. Each device in the network is considered to be a peer with functions that contribute to the network. Each device in a P2P network shares a part of its resources with other networked computers.

Working on computers for long you may have heard the terms Client-Server and Peer-to-Peer. These two are the common network models that we use in our day-to-day life. The Client-Server network model focuses on information sharing whereas, the Peer-to-Peer network model focuses on connectivity to the remote computers. The main difference between the Client-Server and Peer-to-Peer network model is that in Client-Server model, the data management is centralised whereas, in Peer-to-Peer each user has its own data and applications. Further, we will discuss some more differences between Client-Server and Peer-to-Peer network model with the help of comparison chart shown below, just have a look.

Peer-to-peer P2P computing or networking is a distributed application architecture that partitions tasks or workloads between peers. Peers are equally privileged, equipotent participants in the application. They are said to form a peer-to-peer network of nodes. Peers make a portion of their resources, such as processing power, disk storage or network bandwidth, directly available to other network participants, without the need for central coordination by servers or stable hosts. Emerging collaborative P2P systems are going beyond the era of peers doing similar things while sharing resources, and are looking for diverse peers that can bring in unique resources and capabilities to a virtual community thereby empowering it to engage in greater tasks beyond those that can be accomplished by individual peers, yet that are beneficial to all the peers.

The considered technolo gy for realizing such a service can either be a traditional client/server (CS) arch itecture or a peer-to-peer (P2P) network.

Massively Multiplayer Online Games have become very popular among the player community, the game industry and the researchers. As the traditional client-server architecture started to show its limitations, researchers started to develop new architectures that could potentially substitute the client-server model. The peer-to-peer architecture was proposed, but it also had its drawbacks.

Сьюзан отпрянула и попыталась бежать, но призрак схватил ее за руку. - Не двигайся! - приказал. На мгновение ей показалось, что на нее были устремлены горящие глаза Хейла, но прикосновение руки оказалось на удивление мягким. Это был Стратмор. Лицо его снизу подсвечивалось маленьким предметом, который он извлек из кармана.
