Previous Year Question (PYQs)



Match List-I and List-II:


List-I Layer List-II Description
(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





Solution

Physical layer is responsible for transmitting raw bits over a communication channel.

So,

(a) Physical layer $\rightarrow$ (ii)

Transport layer provides true end-to-end communication from source to destination.

So,

(b) Transport layer $\rightarrow$ (iv)

Session layer provides services like dialog control and token management.

So,

(c) Session layer $\rightarrow$ (i)

Presentation layer deals with syntax and semantics of transmitted information.

So,

(d) Presentation layer $\rightarrow$ (iii)

Hence, correct matching is:

(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)
