Network Architecture
The design of computers, devices, and media in a network. And is also categorized as either client/server or peer-to-peer
Client/Server Network
One or more computers act as a server
Server
Controls access to the hardware, software, an other resources on the network, and provides centralized storage area for programs, data, and information
Clients
Other computers and mobile devices on the network that rely on the server for its resources
Dedicated Servers
Perform a specific task and can be placed with same other kind of server to perform multiple tasks
File server, Print server, Database server, Network server, Web server
