Match List I with List II:

List I	List II
(A) Physical layer	(I) Routing of the signals, divide the outgoing message into packets, act as network controller for routing data
(B) Data link layer	(II) Make and break connections, define voltages and data rates, convert data bits into electrical signal
(C) Network layer	(III) Synchronization, error detection, and correction, assemble outgoing message into frames
(D) Presentation layer	(IV) It works as a translating layer

Choose the correct answer from the options given below:

We have to match each OSI layer with its correct function.

First, consider Physical layer.

Physical layer deals with transmission of raw bits over a physical medium.

It defines voltages, data rates, connectors and converts data bits into electrical signals.

So,

$(A)-(II)$

Now, consider Data link layer.

Data link layer converts packets into frames.

It also handles synchronization, error detection and error correction.

So,

$(B)-(III)$

Now, consider Network layer.

Network layer is responsible for routing.

It divides outgoing messages into packets and controls routing of data from source to destination.

So,

$(C)-(I)$

Now, consider Presentation layer.

Presentation layer works as a translating layer.

It handles data translation, encryption, decryption and compression.

So,

$(D)-(IV)$

Final matching is:

$(A)-(II), (B)-(III), (C)-(I), (D)-(IV)$
