Study Notes
Types of Computer Networks
- A Local Area Network (LAN) connects computers within a limited area such as a residence, school, or office building, facilitating resource sharing and communication between devices within the network.
- A Wide Area Network (WAN) spans a large geographical area, connecting LANs and other networks together, often across cities or countries, enabling long-distance communication and access to remote resources.
- A Metropolitan Area Network (MAN) covers a city or a large campus area, interconnecting LANs within a specific geographic area for businesses and organizations.
- A Personal Area Network (PAN) connects devices within the immediate proximity of an individual, like Bluetooth devices, for personal device connectivity and data sharing.
- A Wireless LAN (WLAN) uses wireless communication technology like Wi-Fi to connect devices within a limited area, providing mobility and flexibility in device connectivity without the need for physical cables.
- A Virtual Private Network (VPN) extends a private network across a public network, enabling secure remote access to resources, ensuring privacy and security for data transmitted over public networks.
Node Devices in a Network
- A Router connects multiple networks together, routing data packets between them, and determining the best path for data transmission across networks.
- A Switch connects devices within a LAN, managing data traffic between them, and improving network efficiency by sending data only to the intended device.
- A Hub connects multiple devices in a LAN, passing data packets to all devices connected to them, functioning at the physical layer of the OSI model.
- A Modem converts digital data from a computer into analog signals for transmission over telephone or cable lines, enabling computers to communicate over long distances using existing telephone or cable networks.
- An Access Point (AP) allows wireless devices to connect to a wired network using Wi-Fi, extending the range of a wireless network and providing connectivity to wireless devices.
