Which of the following is not a flow control technique? Correct Answer CRC

CRC is not a flow control technique.

Explanation:-

CRC ( Cyclic Redundancy Check ) is an error-detecting code used to determine if a block of data has been corrupted. The cyclic redundancy check is a technique used to detect errors in digital data.

Important Points

Flow Control Techniques:

  • Flow control refers to a set of procedures used to restrict the amount of data the sender can send before waiting for an acknowledgment.
  • one important aspect of the data link layer is flow control.
  • Flow & Error control technique: Stop-and-wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ.

 

 Additional InformationStop-and-wait ARQ:- Stop and Wait for ARQ mainly implements the sliding window size 1. It is used in Data Link and Transport Layers. It offers error and flows control. Stop-and-wait ARQ is used in connection-oriented communication. 

Go-Back-N ARQ:- It is a specific instance of the automatic repeat request (ARQ) protocol, in which the sending process continues to send the number of frames specified by a window size even without receiving an acknowledgment packet from the receiver.

Selective Repeat ARQ:- It is also known as Sliding Window Protocol and is used for error detection and control in the data link layer. In Selective Repeat ARQ only the loss of error frames are retransmitted frame is received out of sequence.

Based on the given para, answer the following question. Sensitivity considerations often are important in the design of Control Systems. Because all physical elements have properties that change with environment and age, we cannot always consider the parameters of the Control System to be completely stationary over the entire operating life of the system. For instance, the winding resistance of an electric motor changes as the temperature of the motor rises during operation. Control systems with electric components may not operate normally when first turned on because of the still-changing system parameters during warmup. This phenomenon is sometimes called “morning sickness”. Most duplicating machines have a warmup period during which time operation is blocked out when first turn on. A good Control System should be: (a) Very sensitive to parameter variations (b) Insensitive to parameter variations (c) Insensitive to input commands (d) Sensitive to input commands Which of the above are correct?
