LAN works on which of the following Layers? Correct Answer Physical and Datalink

Answer: Option 4

Concept: 

LAN Technologies: 

In LAN technology, There are several technologies such as Ethernet, Token Ring, Token Bus, FDDI ( Fiber Distributed Data Interface ), and ATM (Asynchronous Transfer Mode). Some of these technologies survived for a while, but Ethernet is by far the dominant technology.

1. Ethernet: 

The original Ethernet was created in 1976 at Xerox's Palo Alto Research Center (PARC).
Since then It has gone through four generations: 
a. Standard Ethernet (10 Mbps)
b. Fast Ethernet (100 Mbps)
c. Gigabit Ethernet (1 Gbps)
d. Ten-Gigabit Ethernet (10 Gbps)

Explanation: 

  • LAN works on physical and data link layers.
  • The physical layer defines the means of transmitting raw bits over a physical data link connecting network nodes.
  • The data link layer is the protocol layer in a program that handles the moving of data into and out of a physical link in a network.
