IEEE project 802 divides the data link layer into an upper _____ sublayer and a lower _____ sublayer.
Discuss
Answer & Solution
Answer: Option D
Solution:
The correct answer is Option D: LLC, MAC.
Let's break down why:
The IEEE 802 project standardizes how networks operate.
The Data Link Layer, which is the second layer in the OSI model, is further divided by the IEEE 802 standard into two sublayers:
LLC (Logical Link Control) sublayer:
    This is the upper sublayer.
    It is responsible for flow control, error control, and multiplexing.
    It provides an interface to the network layer.
MAC (Media Access Control) sublayer:
    This is the lower sublayer.
    It is responsible for controlling access to the physical medium (e.g., Ethernet cable, Wi-Fi).
    It handles addressing and framing.
Therefore, IEEE 802 divides the data link layer into an upper LLC sublayer and a lower MAC sublayer.
