WHAT IS NETWORK ARCHITECTURE ?

NETWORK ARCHITECTURE 

• The configuration of computers, devices and media on a network.

CATEGORIES OF NETWORK :-

• PEER TO PEER NETWORK
• CLIENT/SERVER NETWORK

PEER TO PEER NETWORK

• A simple, inexpensive network that typically connects fewer  than 10 computers.
• Each computer has equal responsibilities and capabilities. 
• Allows users to set up a peer-to-peer network.
• Each computer stores files on its own storage devices.
• All computers on the network share any peripheral device(s) attached to any computer. 
• Ideal for very small businesses and home user
• Directly available without the need for central coordination by servers or stable hosts.

CLIENT/SERVER NETWORK

• One or more computers act as a server, and the other computers on the network request services from the server.
• Server : host computer, controls access to the hardware, software and provides a centralized storage area for programs, data and information.
• Clients  rely on the server for its resources.
• Client computer sends a resource or process request to the server over the network connection
• Server can manage several clients simultaneously
• Web server serves many simultaneous users with Web page and or website data.
