In computer networking, there are three roles that can be run by computers in the LAN (Local Area Network). The first can be a client role, that is just as users but does not provide network resources to be shared on the network and used by another member. The second role can be a peer, which is a client that uses the network resources while providing the so-called peer - to- peer. Finally, the role can be a server that provides network resources. Based on the above three roles, the computer network further divided into 3 parts:
- Network - based server and client - server , defined by the presence server in a network that provides security mechanisms and administration of the network. The network consists of many clients and one or more servers. Clients commonly referred to as front-end computer, ask for services such as storage and data printing to a network printer, while the server is often referred to as a back- end computers deliver the request to the appropriate destination.
- Peer-to - per. In a simple network is described, every computer on the network peer - to- peer functions as a client and server at the same time.
- Hybrid networks, are networks of computers that have all contained in the above two types of networks. This means that users in this hybrid network can access resources to share or be shared by a peer-to - peer, at a time when the same while also capitalize upon the resources provided by a server computer.
