Question

Layer of the OSI model that handles error recovery, flow control (synchronization), and sequencing (which terminals are sending and which are receiving).

a. Network Layer
b. Transport Layer
c. Data Link Layer
d. Physical Layer

Answer 1

The Transport Layer handles error recovery, flow control, and sequencing in the OSI model.

Step-by-step explanation:

The layer of the OSI model that handles error recovery, flow control (synchronization), and sequencing (which terminals are sending and which are receiving) is the Transport Layer.

The Transport Layer is responsible for ensuring reliable delivery of data between two hosts in a network. It provides error recovery by re-transmitting lost or corrupted packets, flow control by managing the rate at which data is sent, and sequencing by ensuring that data packets are delivered in the correct order.

For example, the Transmission Control Protocol (TCP) is a commonly used protocol in the Transport Layer that provides these functionalities.
