What does ARQ stand for?

1. Automatic Repeat reQuest (ARQ)

Definition and Purpose

Automatic Repeat reQuest (ARQ) is a protocol used in data transmission systems to ensure reliable communication by automatically requesting the retransmission of corrupted or lost data packets. ARQ mechanisms detect errors in transmitted data and prompt the sender to resend the affected packets.

Components and Functionality

ARQ protocols involve error detection methods, such as checksums or CRCs, to identify corrupted packets. When an error is detected, the receiver sends a negative acknowledgment (NACK) back to the sender, which then retransmits the erroneous packet. Common ARQ schemes include Stop-and-Wait ARQ, Go-Back-N ARQ, and Selective Repeat ARQ.


ARQ protocols are crucial for maintaining data integrity and reliability in communication networks. They are widely used in various applications, including computer networks, wireless communication, and satellite systems.

2. Asynchronous Response Queue (ARQ)

Definition and Functionality

Asynchronous Response Queue (ARQ) refers to a queuing system used in computing and telecommunications to handle responses from asynchronous operations. It allows for the orderly processing of responses that arrive at different times, ensuring that each response is handled efficiently.

Components and Mechanisms

ARQ systems use queues to store incoming responses until they can be processed. They often involve event-driven programming and callback functions to manage the asynchronous nature of operations, ensuring that responses are processed in the correct order.


ARQ systems enhance the efficiency and responsiveness of applications by allowing them to handle multiple asynchronous operations concurrently. They are essential for web applications, real-time communication systems, and distributed computing environments.

It helps maintain the integrity and efficiency of data transmission by ensuring that relay nodes are synchronized with the sender and receiver.

Components and Operation

ARQ systems involve periodic querying of relay nodes to verify the status of data packets. If discrepancies or errors are detected, corrective actions such as retransmission or re-routing are initiated to maintain data flow.


ARQ enhances the reliability and robustness of communication networks by providing mechanisms for error detection and correction at relay points. It supports continuous and efficient data transmission in complex network topologies.

7. Access Request Queue (ARQ)

Definition and Usage

Access Request Queue (ARQ) is a system used in network security and access control to manage and process incoming requests for access to resources or services. It ensures that access requests are handled in a timely and orderly manner.

Components and Workflow

ARQ systems involve queuing mechanisms that prioritize and process access requests based on predefined policies and criteria. They may include authentication, authorization, and auditing components to ensure secure access control.


ARQ systems play a critical role in maintaining the security and efficiency of networked systems. They help prevent unauthorized access, manage user permissions, and ensure that access to resources is granted appropriately.
