A megabit per second, or Mbps, is a unit of data transfer speed that tells you how many million bits of information move through a network each second. It's commonly used by internet providers to advertise download and upload rates, so when you see a plan offering '100 Mbps,' it means you can theoretically download a 12.5-megabyte file in one second. Real-world speeds often vary based on network congestion, router quality, and connection type.
