Final answer:
Megabit per second (Mbps) is a unit of measurement for data transfer rate, and is typically used to describe internet speed and network capabilities.
Step-by-step explanation:
Megabit per second (Mbps) is a unit of data transfer rate used to measure how much data can be transferred over a network in one second. It is commonly used to describe internet speed or the speed of a computer network. For example, a connection with a download speed of 25 Mbps would be faster and more capable of handling large downloads or streaming high-definition video than a connection with a slower speed.
When we're talking about memory card speeds, higher Mbps signifies a card's ability to write and read data more quickly, which is crucial for applications like high-resolution video recording where data needs to be written to the card rapidly.
