During TCP/IP communications between two network hosts, information is encapsulated on the sending host and decapsulated on the receiving host using the OSI model. Match the information format with the appropriate layer of the OSI model.

a. Packets
b. Segments
c. Bits
d. Frames

1. Session Layer
2. Transport Layer
3. Network Layer
4. Data Link Layer
5. Physical Layer

When TCP/IP protocols are used for communication between two network hosts, there is a process of coding and decoding also called encapsulation and decapsulation.

This ensures the information is not accessible by other parties except the two hosts involved.

Operating Systems Interconnected model (OSI) is used to standardise communication in a computing system.

There are 7 layers used in the OSI model:

1. Session Layer

2. Transport Layer

3. Network Layer

4. Data Link Layer

5. Physical Layer

6. Presentation layer

7. Application layer

The information formats given are matched as

a. Packets - Network layer

b. Segments - Transport layer

c. Bits - Physical layer

d. Frames - Data link layer
