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

What are the examples of dedicated servers?

Peer-to-Peer Network

It is a simple, inexpensive network that typically connects fewer than 10 computers

Peer-to-Peer Network

This type of network is ideal for every small businesses and home users

Internet Peer-to-Peer

also called as P2P

Internet Peer-to-Peer

It describes an internet network on which users access each other's hard disks and exchange files directly

File Sharing Network

Peer-to-peer network is sometimes

Network Topology

It refers to the layout of the computers and devices in a communications network

Star Network
