DRAG DROP
Click and drag the Open Systems Interconnection (OSI) layers to their corresponding functions on the right.
Select and Place:

Answer:

Explanation:
The following are the OSI layers along with their descriptions:
– Application: Responsible for interacting directly with the application. It provides application services such as e-mail and File Transfer Protocol (FTP).
– Physical: Consists of hardware for sending and receiving data on a carrier. The protocols which work at the Physical layer include Fast Ethernet, RS232, and
Asynchronous Transfer Mode (ATM).

– Transport: Responsible for error-free and sequential delivery of data. This layer is used to manage data transmission between devices, a process known as flow
control. The Transport layer protocols are Transmission Control Protocol (TCP) and User Datagram Protocol (UDP).
– Network: Used to define the network address or the Internet Protocol (IP) address, which is then used by the routers to make routing decisions.
– The following are also OSI layers:
– Presentation: Enables coding and conversion functions for application layer data. The formatting and encryption of data is done at this layer. The Presentation
layer converts data into a format which is acceptable by the application layer.
– Session: Used to create, manage, and terminate sessions between communicating nodes. The session layer handles the service requests and service responses,
which take place between different applications.
– Data Link: Ensures the reliable transmission of data across a network on the basis of Layer 2 addresses such as MAC addresses (Ethernet) or DLCIs (Frame
Relay).
