---

Match List-I and List-II:

List - I	List - II
a. Physical layer	i. Provide token management service
b. Transport Layer	ii. Concerned with transmitting raw bits over a communication channel
c. Session layer	iii. Concerned with the syntax and semantics of the information transmitted
d. Presentation layer	iv. True end-to-end layer from source to destination

Choose the correct option from those given below :

1. 1. (a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)
2. 2. (a)-(iv), (b)-(iii), (c)-(ii), (d)-(i)
3. 3. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)

Answer : 3. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)

Explanation Question 132

• Physical layer → Concerned with transmitting raw bits over a communication channel
• Transport layer → True end-to-end layer from source to destination
• Session layer → Provide token management service
• Presentation layer → Concerned with the syntax and semantics of the information transmitted

So, option 3 is correct answer
