Data Feed
A data feed is a continuous stream of structured information transmitted from a source to a recipient, often in real-time for immediate use. In modern applications, it's essential for keeping systems updated, like powering stock market apps or social media timelines, and has evolved to handle massive volumes of data securely across the internet.
Did you know?
The first commercial data feeds revolutionized global finance when the Reuters news agency began transmitting stock prices via telegraph in 1851, allowing traders in London to get New York market updates in minutes rather than weeks. This innovation paved the way for today's high-frequency trading, where algorithms process data feeds at speeds up to 50,000 trades per second.
