Types of Networks - JSS2 Computer Studies Lesson Note
-
Local Area Network (LAN): A LAN is a network that connects devices within a limited geographical area, such as a home, office, or school. It enables quick and efficient communication between connected devices. Examples include a home Wi-Fi network connecting computers, smartphones, and printers.
Wide Area Network (WAN): WANs cover a broader geographical area, connecting LANs across cities, countries, or even continents. The internet is a vast example of a WAN, allowing global communication and data exchange. Businesses often use WANs to connect their offices spread across different locations.
Metropolitan Area Network (MAN): A MAN falls between LANs and WANs, covering a larger geographical area than a LAN but not as extensive as a WAN. MANs connect multiple LANs within a city or metropolitan region. Cable television networks and city-wide Wi-Fi networks are examples of MANs.
Personal Area Network (PAN): A PAN is a small network designed for personal devices within the immediate surroundings of an individual. Bluetooth technology is commonly used for PANs, connecting devices like smartphones, laptops, and wearable gadgets.
Wireless Local Area Network (WLAN): WLANs are similar to LANs but use wireless communication instead of physical cables. Wi-Fi networks are popular examples of WLANs, providing flexibility and convenience for device connectivity within a specific area.
Virtual Private Network (VPN): A VPN creates a secure and private connection over the internet, allowing users to access resources as if they were directly connected to a private network. VPNs are commonly used for remote work, ensuring data security and privacy.
