Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
In respect of osi model, LANs implement
A
Lower two Layers
B
All seven Layers
C
Upper Five Layers
D
None of above
Explanation: 

Detailed explanation-1: -The 7 layers of the OSI model. The layers are: Layer 1-Physical; Layer 2-Data Link; Layer 3-Network; Layer 4-Transport; Layer 5-Session; Layer 6-Presentation; Layer 7-Application.

Detailed explanation-2: -1. Physical. The lowest layer of the OSI model is concerned with data communication in the form of electrical, optic, or electromagnetic signals physically transmitting information between networking devices and infrastructure.

Detailed explanation-3: -Easy. Keep in mind that while certain technologies, like protocols, may logically “belong to” one layer more than another, not all technologies fit neatly into a single layer in the OSI model. For example, Ethernet, 802.11 (Wifi) and the Address Resolution Protocol (ARP) procedure operate on >1 layer.
