The word "retransmission" is spelled with the prefix "re-", meaning "again", followed by "transmission". The phonetic transcription of "re-" is /ɹiː/, and "transmission" is /tɹænzˈmɪʃən/. Together, the word is pronounced as /ɹiːtɹænzˈmɪʃən/, with the syllable stress on the second syllable. "Retransmission" refers to the process of sending a message or signal again after it was not properly received, such as in telecommunications or broadcasting. Proper spelling is important for clear communication and understanding.
Retransmission is a term used in telecommunications and computer networks to describe the process of transmitting a data packet or message again, after it has been lost, corrupted, or unable to reach its intended destination.
In computer networks, data is usually transmitted in the form of packets, which are discrete units of information. These packets travel along the network from the sender to the receiver through various intermediate network nodes. However, in certain cases, packets can get lost or damaged due to various network issues such as congestion, interference, or errors.
Retransmission provides a mechanism to overcome these issues and ensure reliable communication. When a packet is lost or corrupted, the sender or an intermediate node can detect this by not receiving an acknowledgment or by identifying errors in the received packet. In response, the sender can retransmit the lost or corrupted packet. This process is often automated and controlled by protocols such as the Transmission Control Protocol (TCP) used in the Internet.
Retransmission serves to enhance the integrity and reliability of data transmission by compensating for any errors or disruptions that may occur during the transmission process. It helps ensure that the intended message or data arrives at its destination intact, enabling effective communication across networks.
The word "retransmission" is derived from the combination of two Latin roots: "re-" and "transmissionem".
1. The prefix "re-" in Latin means "again" or "back". It is often used to indicate repetition or returning to a previous state. In the case of "retransmission", it signifies the act of transmitting again or repeating the process of transmission.
2. The Latin root "transmissionem" comes from the verb "transmittere" which means "to send across" or "to pass on". It is derived from the combination of "trans" meaning "across" and "mittere" which means "to send".
Thus, the etymology of "retransmission" can be understood as the act of transmitting something again or sending it across once more.
