Answer:

Explanation:
File Transfer Protocol (FTP) and Telnet are services, which are implemented at the Application layer in the
Open Systems Interconnection (OSI) model. The Application layer is responsible for interacting directly with the
application. It provides application services, such as e-mail.
Motion Picture Experts Group (MPEG) and Tagged Image File Format (TIFF) are graphic image formats, which
are implemented at the Presentation layer. The Presentation layer enables coding and conversion functions for
application layer data. Data is formatted and encrypted at this layer. The Presentation layer converts data into a
format which is acceptable to the Application layer.
The following are also OSI layers and their descriptions:
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.
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.
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).
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).
