Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
The data link layer takes the packets from ____ and encapsulates them into frames for transmission.
A
network layer
B
physical layer
C
transport layer
D
application layer
Explanation: 

Detailed explanation-1: -Data-link layer takes packets from Network Layer and encapsulates them into Frames. Then, it sends each frame bit-by-bit on the hardware. At receiver’ end, data link layer picks up signals from hardware and assembles them into frames. Data-link layer provides layer-2 hardware addressing mechanism.

Detailed explanation-2: -The network layer encapsulates segments from the transport layer. Its primary aim is to forward packets to routers within interconnected, heterogeneous networks. A network packet is originated from a logical address and transferred to another one. Therefore, its header contains the source and destination addresses.

Detailed explanation-3: -The Data link layer describes the logical organization of data bits transmitted on a particular medium. This layer defines the framing, addressing, and check-summing of Ethernet packets.
