What are the advantages of using OSI layered model?
What are the advantages of using OSI layered model?
The advantages of the OSI model are It distinctly separates services, interfaces, and protocols. Hence, it is flexible in nature. Protocols in each layer can be replaced very conveniently depending upon the nature of the network. It supports both connection-oriented services and connectionless services.
What is advantage of session layer?
The session layer builds a transmission bridge to provide more efficient long-term transport, as well as a way to better organize simultaneous communication of multiple network applications. When the communication between network applications is complete, session layer services terminate the connection.
Which TCP IP model is the combination of session presentation and application layer of OSI model?

What are the responsibilities of presentation layer and session layer of OSI model?
The presentation layer takes any data transmitted by the application layer and prepares it for transmission over the session layer. The session layer creates communication channels, called sessions, between devices.
What are the advantages of using layered architecture in computer networks?
Terms in this set (7)
- Reduces complexity. It breaks network communication into smaller, simpler parts.
- Standardizes interfaces.
- Facilitates modular engineering.
- Interoperability between Vendors.
- Ensures interoperable technology.
- Accelerates evolution.
- Simplifies teaching and learning.
What is session and presentation layer?
The session layer is meant to store states between two connections, like what we use cookies for when working with web programming. The presentation layer is meant to convert between different formats. This was simpler when the only format that was worried about was character encoding, ie ASCII and EBCDIC.
What is application layer in TCP IP?
The application layer is the highest abstraction layer of the TCP/IP model that provides the interfaces and protocols needed by the users. It is used to develop network-based applications. It provides user services like user login, naming network devices, formatting messages, and e-mails, transfer of files etc.
What is the main advantage of UDP?
What is the main advantage of UDP? Explanation: As UDP does not provide assurance of delivery of packet, reliability and other services, the overhead taken to provide these services is reduced in UDP’s operation. Thus, UDP provides low overhead, and higher speed.
What is the main responsibility of application layer of IoT?
The critical goal of Internet of things (IoT) is to ensure effective communication between objects and build a sustained bond among them using different types of applications. The application layer is responsible for providing services and determines a set of protocols for message passing at the application level.
