In the context of a small to medium office, the following are examples of LAN (Local Area Network) devices commonly used to establish and support network connectivity:
-
Router: Connects the office network to the internet and manages traffic between devices within the LAN and external networks.
-
Switch: Connects multiple devices within the network, allowing them to communicate with each other efficiently. It operates at the data link layer and can be managed or unmanaged.
-
Access Point (AP): Extends the wireless network coverage by connecting to a wired network to allow wireless devices to access resources.
-
Network Bridge: Connects two segments of a network and allows them to function as a single network, often used to eliminate collisions between devices on a LAN.
-
Network Hub: Although less common in modern networks, it can still be found in some setups. It connects multiple Ethernet devices, making them act as a single network segment.
-
Firewall: A network security device that monitors and controls incoming and outgoing network traffic based on predetermined security rules, protecting the LAN from external threats.
-
Modem: Converts digital signals from the router into analog signals for transmission over telephone lines or vice versa, allowing internet access for the network.
-
Network Attached Storage (NAS): A dedicated file storage device that provides data access to a heterogeneous group of clients over a LAN.
-
Print Server: A device or server that connects printers to the network, allowing multiple users to share a single printer remotely.
-
VoIP Phones: Internet-based phones that connect to the network, allowing for voice communication over IP.
-
Wireless Range Extender: A device that boosts the range of the wireless network, improving connectivity for devices that are further away from the main router.
-
Power over Ethernet (PoE) Switch: A switch that provides power along with data connectivity to PoE-enabled devices such as IP cameras and VoIP phones.
By utilizing these devices, a small to medium office can create a functional and efficient LAN that supports a variety of networking needs.
