Frequently Asked Question on LAN (Local Area Network)
How do LANs relate to the rest of the Internet?
LANs are essential for organizing and managing local network traffic, providing a controlled and efficient environment for internal communication. They connect to the Internet via routers, which handle the translation of internal IP addresses to a public IP, facilitate DNS resolution, and enforce security policies to safeguard the network. This integration allows LANs to access and provide services on the global Internet while maintaining internal network organization and security.
What are the uses of LAN?
The computer hardware in a confined space, like a home or workplace, is connected via a local-area network (LAN). LANs typically connect computers to one another and to a range of peripheral devices, such printers, using cable connections.
Which device is most commonly used in LANs, and why?
A single router is typically used in residential LANs to build the network and control all of the connected devices. The router serves as a hub for connections, allowing computers, tablets, and cellphones to speak with one another.
What is LAN Security?
A network must be secured after it has been set up. The L2/L3 switches’ and any existing routers’ security settings can be used to accomplish this. Network security can also be improved by utilising hardware-based security measures like full disc encryption, fingerprint recognition, and security tokens. Additional security packages can be downloaded locally or purchased via a software as a service (SaaS) delivery mechanism to defend and maintain the network perimeter.
What is Network Topology? List 5 Popular Network Topologies.
Network topologies figure how devices in a LAN are connected, as well as how data is traversed from one node to another. These are five popular topologies as follow:
LAN Full Form
A Local area network (LAN) is a network that is used to link devices in a single office, building, or campus of up to a short distance. LAN is restricted in size. In LAN networks internet speed is from 10 Mbps to 100 Mbps (But now much higher speeds can be achieved). The most common topologies used in LAN networks are bus, ring, and star.
