a) Transport
b) Network
c) Data link
d) Application
Answers
Answer:
is an Application layer protocol that is responsible for moving messages from one e- mail server to another in the TCP/IP protocol suite
Answer:
Transport layer
Within a layered architecture of protocol and other network elements, the transport layer facilitates communication among application running processes on various hosts.
Explanation:
The Transport Layer offers dependable data transmission services to the upper layers by facilitating transparent data flow among end users. Using flow control, segment and desegmentation, and error management, the transport layer manages the dependability of a specific link.
The fourth layer from the top is the transport layer. The transport layer's primary responsibility is to directly offer communication services to application processes running on various hosts. Logical communications among app running processes on several hosts is provided by the transport layer.
A complete end-to-end solution for dependable communications is offered by the transport layer. In order to efficiently regulate communications between two hosts, TCP/IP depends on the transport layer. The transport layer is utilized to establish this connections whenever an IP communication sessions has to start or stop.
- The transport layer is in charge of managing data packet delivery.
- It controls data flow, segmentation, desegmentation, and error handling
- There are five types in the transport protocol, numbered 0 through 4. (TP0 to TP4)
- Data packets are broken up and put back together at this level.
