12. AQA GCSE (8525) SLR3 - 3.5 Types of networks
AQA Specification Reference - Section 3.5 This video explores the three main types of networks: local area networks (LAN), wide area networks (WAN) and personal area networks (PAN). The reasons for networking stand-alone computers are outlined, and the potential disadvantages too. The connection options for devices on a network are briefly mentioned and covered in more detail in other videos in this topic.

Understanding Network Types
Overview of Network Types
- The video discusses three main types of networks essential for exams: WANs (Wide Area Networks), LANs (Local Area Networks), and PANs (Personal Area Networks).
- Standalone computers, which are not connected to any network, can benefit from networking through file sharing, peripheral sharing (like printers), and enhanced communication options.
Local Area Networks (LAN)
- A LAN covers a small geographical area, typically within a single site or building. The hardware is usually owned by the organization using it.
- LAN connections often utilize UTP cables, fiber-optic cables, or wireless communication via Wi-Fi.
Wide Area Networks (WAN)
- WANs cover larger geographical areas and connect multiple LANs together. They rely on infrastructure managed by telecommunications companies.
- Connections in WAN may include telephone lines, fiber optic cables, or satellite links.
Home Networking Devices
- In home networks, a single device known as a router often combines the functionalities of a wireless access point, switch, and router into one unit.
Personal Area Networks (PAN)
- A PAN is used for data transmission among localized devices like cell phones and laptops. Bluetooth is the most common technology used in PAN with a short range of about 10 meters.
