What is the OSI Application layer responsible for?
|
It establishes the availability of intended communication partners, synchronizes, and establishes agreements on procedures for error recovery and control of data recovery.
|
|
|
What is the OSI Presentation Layer responsible for?
|
Translation of codes so the application layer of the receiving host can read the data sent by the sending host.
|
|
|
What is the OSI Session Layer responsible for?
|
It establishes, manages, and terminates sessions between two communicating hosts. Responsible for efficient data transfer, class of service, and exception reporting.
|
|
|
What is the OSI Transport Layer responsible for?
|
It segments data from the sending host and reassembles it for the receiving host. Establishes, maintains, and terminates virtual circuits. Error detection, flow control, and reliability.
|
|
|
What is the OSI Network Layer responsible for?
|
It provides connectivity and path selection.
|
|
|
What is the OSI Data Link layer responsible for?
|
It defines how data is formatted for transmission and how access to the network is controlled.
Includes addressing and control signaling between devices. |
|
|
What is the OSI Physical layer responsible for?
|
It defines electrical, mechanical, procedural, and functional specifications for activating, maintaining, and deactivating physical links.
|
|
|
TCP/IP Application layer does?
|
It handles high level protocols, including issues of representation, encoding and dialog control.
It combines all application related issues into one layer and ensures data is properly packaged. |
|
|
TCP/IP Transport Layer does?
|
It deals with QoS issues of reliability, flow control, and error correction. TCP provides reliable network communications.
|
|
|
TCP/IP Internet Layer does?
|
It sends source datagrams from any network on the internetwork and has them arrive at the destination - regardless of the path they took to get there.
|
|
|
TCP/IP Network Access layer does?
|
It includes LAN and WAN protocols.
It includes all details of the OSI physical and data link layers. |
