Which Scenario Describes A Function Provided By The Transport Layer Top 19 Favorites

The transport layer in the OSI (Open Systems Interconnection) model is responsible for end-to-end delivery of data between applications running on different hosts. It provides a number of functions to ensure reliable, efficient, and error-free communication between these applications.

Here are a few scenarios that describe functions provided by the transport layer:

1. A user wants to transfer a large file from one computer to another over the internet. The transport layer provides segmentation of the data into smaller chunks, which can be sent and received more efficiently. It also provides flow control to ensure that the receiving computer can handle the data at the rate it is being sent.

2. An application needs to establish a connection with another application running on a remote computer. The transport layer provides connection-oriented services that establish, maintain, and terminate connections between the two applications. It also provides error detection and correction mechanisms to ensure that data is transmitted reliably.

3. A user is streaming a video over the internet. The transport layer provides a mechanism for ensuring that the data is delivered in the correct order, even if it is received out of order due to network congestion or other issues. It also provides congestion control mechanisms to prevent the network from becoming overloaded and dropping packets.

Overall, the transport layer provides a range of functions that ensure reliable, efficient, and error-free communication between applications running on different hosts.

The application layer protocol that uses message types such as GET, PUT, and POST is the Hypertext Transfer Protocol (HTTP).

GET is used to retrieve information or data from a server, while PUT is used to update or replace existing information on a server. POST is used to submit data to be processed by a web server.

HTTP is the foundation of data communication for the World Wide Web, and it is used by web browsers and servers to exchange information and resources over the internet. It is an important protocol for accessing and retrieving information from web servers, and it is widely used in web applications, APIs, and other online services.

HTTP, which stands for Hypertext Transfer Protocol, is designed to transfer data over the internet between clients and servers. TCP, which stands for Transmission Control Protocol, is a transport layer protocol that provides reliable and ordered data transmission between two devices.

There are several reasons why HTTP uses TCP as the transport layer protocol:

1. Reliability: TCP provides reliable data transmission by ensuring that all data packets are delivered to the destination in the correct order, without any loss or duplication of packets. This is important for HTTP, which is used to transfer important data such as web pages, images, videos, and other content.

2. Connection-oriented: TCP establishes a connection between two devices before transferring data, which ensures that data is delivered to the correct destination. This is important for HTTP, which requires a reliable connection between the client and server to transfer data.

3. Flow control: TCP provides flow control, which ensures that the sender does not overwhelm the receiver with too much data. This is important for HTTP, which transfers large amounts of data and needs to ensure that the receiver can handle the data flow.

4. Congestion control: TCP also provides congestion control, which prevents the network from becoming congested by limiting the amount of data that can be sent over the network. This is important for HTTP, which is used by millions of users worldwide and needs to ensure that the network is not overwhelmed with traffic.

Overall, TCP provides the necessary features for reliable, ordered, and efficient data transmission, which makes it the ideal transport layer protocol for HTTP.
