Write Characteristics Of LAN.

A Local Area Network (LAN) is a type of computer network that covers a relatively small area, typically a single building or campus. The following are some of the key characteristics of LAN:

  1. Geographical scope: LANs are designed to serve a relatively small geographical area, typically within a single building, campus, or office complex.

  2. Ownership: LANs are often owned and controlled by a single organization, such as a company, government agency, or educational institution.

  3. Transmission technology: LANs typically use wired transmission technologies, such as Ethernet, twisted pair cables, or fiber optic cables, although wireless technologies such as Wi-Fi can also be used.

  4. Topology: The most common topology used in LANs is the star topology, in which all devices are connected to a central hub or switch. Other topologies, such as bus, ring, or mesh, can also be used.

  5. Data transfer rate: LANs typically have high data transfer rates, ranging from 10 Mbps to 10 Gbps or higher, depending on the transmission technology used.

  6. Protocol standards: LANs typically adhere to industry-standard protocols and technologies, such as TCP/IP, Ethernet, and Wi-Fi, to ensure compatibility and interoperability between different devices and networks.

  7. Security: LANs often incorporate security features such as firewalls, access control, and encryption to protect against unauthorized access, data breaches, and other security threats.

Overall, LANs are designed to provide reliable, high-speed communication and data transfer capabilities within a small area, enabling efficient collaboration and sharing of resources among users and devices.
