Question
IDENTIFY AND COMPARE DIFFERENT LAN PROTOCOLS
Answers
GPT 3.5
There are several LAN protocols used in networking, but two of the most common and widely used are Ethernet and Wi-Fi.
Ethernet:
- Ethernet is a wired LAN protocol that uses a physical medium such as twisted pair cables or fiber optic cables to connect devices within a local area network.
- It operates on the OSI model's Data Link Layer (Layer 2) and uses the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) access method to manage network traffic.
- Ethernet speeds range from 10 Mbps (Ethernet) to 100 Gbps (Ethernet).
Wi-Fi:
- Wi-Fi, also known as IEEE 802.11, is a wireless LAN protocol that uses radio waves to connect devices within a local area network.
- It operates on the OSI model's Physical and Data Link Layers (Layer 1 and Layer 2) and uses Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) access method to manage network traffic.
- Wi-Fi speeds range from 11 Mbps (802.11b) to 10 Gbps (802.11ax).
Comparison:
- Ethernet is typically faster and more reliable than Wi-Fi, especially in scenarios where a high-speed, low-latency connection is needed.
- Wi-Fi offers greater flexibility and mobility compared to Ethernet, as it allows wireless devices to connect to the network without the need for physical cables.
- Wi-Fi is more susceptible to interference from other wireless devices and obstacles such as walls and distance, while Ethernet is generally more stable and secure.
- Ethernet is more commonly used in enterprise environments or for high-bandwidth applications, while Wi-Fi is more prevalent in home and small business networks.
