Network architecture is classified into two categories:
Client-Server Architecture
Client-server architecture (client/server) is a network architecture in which each computer or process on the network is either a client or a server.
Servers are powerful computers or processes dedicated to managing disk drives (file servers), printers (print servers), or network traffic (network servers). Typically servers provide services to any client.
Clients are PCs or workstations on which users run applications. Clients depend on servers for resources, such as files, devices, and even processing power.

Peer-to-Peer Architecture
In the peer-to-peer architecture model, a system is decomposed into computational nodes that have equivalent capability & responsibility. Another type of network architecture is known as a peer-to-peer architecture because each node has equivalent responsibilities. Both client/server and peer-to-peer architectures are widely used, and each has unique advantages and disadvantages.
An example of peer –to –peer architecture is a system of intelligent agents that collaborate to collect, filter & correlate information.

Up-Link: An up-link is the portion of a communications link used for the transmission of signals from an earth terminal to a Satellite. An uplink is inverse of down-link.
In the GSM cellular network, the radio uplink is the transmission path from the mobile station (cell phone) to the base station (cell site).In a computer network, an uplink is a connection from data communication equipment toward network core.
It is also a known upstream connection.
Downlink is the link from satellite to ground station. In the case of GSM cellular networks, the radio downlink is the transmission path from a cell site to cell phone. In computer networks, a downlink is a connection from data communication equipment toward data terminal equipment.It is also known as the downstream connection.
The cross-link is the communication path among satellites. It is the way several satellites contribute the data communication.
Communication Processor
• The communications processors (CPs) is that they are general-purpose devices from a family of equipment types, including feeder multiplexers, packet assembler/disassembler (PADs), terminal servers, and protocol converters.
• Communications processors on the other hand, are generally classed by their range of features, flexibility, and capabilities. These include the number and types of host interfaces and protocols supported, aggregate bandwidth, and the types of terminal equipment and other devices supported.
