Definīcija: A message transmitted to indicate that data has been received correctly. The Transmission Control Protocol (TCP) requires that the recipient acknowledge successful receipt of data. Such acknowledgments (ACKs) generate additional network traffic, decreasing the rate at which data passes but increasing reliability. To reduce the impact on performance, most hosts send an acknowledgment for every other segment or when a specified time interval has passed.
Definīcija: Speciāla veida vadības ziņojums vai signāls, ar kuru lietotāji apmainās sadarbības gaitā. Ar apliecinājumu apstiprina pārraidītā ziņojuma saņemšanu.
