A megabit is a unit of digital information that equals one million bits. It is commonly used to measure data transfer speeds in computer networks and internet connections. For example, a speed of 10 megabits per second (Mbps) indicates that 10 million bits of data can be transmitted every second. In the context of data storage, a megabit is often confused with a megabyte, which is eight times larger. Understanding the difference is important for tasks like downloading files or streaming videos, where data rates are typically expressed in megabits per second. This helps users gauge how quickly they can access content online.
