ARQ

ARQ (Automated Request) is a computer networking protocol designed to reduce the amount of manual intervention needed on the part of the user when requesting data from a remote computer. It works by pre-defining a set of rules that the requesting computer will use to send data to the remote computer, allowing for more efficient data transfers and eliminating potential delays.

ARQ is based on the TCP/IP protocol, allowing computers to communicate with each other over a network. It utilizes an algorithm to dynamically adjust and optimize the size of data transmission packets for maximum efficiency. By breaking up the data into smaller chunks, ARQ can make sure that each piece is delivered correctly without the need for manual intervention.

The protocol was first developed in the late 1970s by a team of engineers working at Bell Labs. Since then, it has become a widely used protocol, with applications in many areas of computer networking. It is especially valuable in areas such as telemetry and internet-of-things, where large amounts of data must be transmitted over extended periods of time.

In addition to its efficiency, ARQ offers a number of features including acknowledgments, error checking, and retransmissions of lost or misdelivered data. This makes it highly reliable for applications where accuracy is paramount.

Overall, ARQ has become a cornerstone of computer networking due to its reliability and efficiency. It is an essential part of any computer network, especially for applications that require large amounts of data to be sent over a long period of time.
