Ethernet LANs are the bedrock of local networking. These LANs employ wired connections to transmit data and are characterized by their reliability and speed. Here are some key features of Ethernet LANs
Topology: Ethernet LANs can be set up in various topologies, such as star, bus, or ring, but the star topology is the most common in modern setups. In a star topology, all devices connect to a central hub or switch.
Physical Media: Ethernet LANs use physical cables, typically twisted-pair copper cabling (e.g., Cat 5e or Cat 6) or fiber optic cables for data transmission. This ensures high data transfer rates and minimal interference.
Reliability: Wired connections are generally more reliable than wireless ones, making Ethernet LANs ideal for critical applications like data centers and business networks.
Wireless LANs (Wi-Fi): The Wireless Revolution
Wireless LANs, commonly known as Wi-Fi networks, have revolutionized how we connect to the internet. They provide the flexibility of mobility without the constraints of physical cables. Here are the key aspects of Wi-Fi LANs:
Topology: Wi-Fi networks typically use a star topology, where wireless access points (routers) serve as the central hubs and wireless devices connect wirelessly to these access points.
Connectivity: Wi-Fi enables devices to connect to the network without the need for physical cables, offering mobility and convenience. It’s the go-to choice for homes, offices, and public spaces.
Standards: Wi-Fi technology has evolved over the years, with standards like 802.11n, 802.11ac, and 802.11ax (Wi-Fi 6) providing increased speed, capacity, and security.
Challenges: While Wi-Fi offers unparalleled convenience, it can face challenges such as interference, signal strength, and security concerns, which need to be addressed for optimal performance.
