Core Principles of Computer Networking

Types of networks

Local area networks (LANs) - Cover a small geographic area, such as a home or office building.
- LAN’s are often wired using Ethernet cables and switches.
- They can be wireless using WAP’s. This would be called a WLAN (Wireless local area network).
Metropolitan area network (MAN) - Covers a City, Town or Campus area.
Personal area network (PAN) - Covers a very small area, typically a few meters.
- Examples include Bluetooth and NFC (Near Field Communication).
