11.1.2 Network Types

Learn the different types of networks there are.

The different network types help classify networks.

Host Role Networks

Below are the different types of host role networks.

Peer to Peer

Each host in a peer-to-peer network can access the other hosts and the resources they have, however each host controls who has access to the resources they own.

• easy implementation
• cheap
• not scalable
• hard to support
• no centralized control or storage

Client Server

Each host in a client-server has one of two roles. Either they have a server role, which grants them the right to direct network resources to hosts, or they have the client role, which means that they can request and use network resources (if granted).

• easy implementation
• cheap
• not scalable
• hard to support
• no centralized storage

Geographical Networks

Below are the different types of geographically-based networks.

Body Area Network (BAN)

Very small network that consists of wearable or implanted mobile devices.

• smart watch
• fitness tracker
• medical implants

Personal Area Network (PAN)

Very small network used for communication between personal devices

• wireless earbuds & mobile phone via Bluetooth
• limited to a few feet in rang

Local Area Network (LAN)

Small network based to encompass a geographical area, like an office. Typically uses wires to connect systems.

Wireless LAN (WLAN)

Covers about the same area as a normal LAN. Uses radio signals to connect systems instead of wires.

Wide Area Network (WAN)

A group of LANs that are geographically separated/isolated from one another, but are connected to form a large internetwork.
