Data usage refers to the amount of digital information consumed or transmitted over a network, typically measured in megabytes (MB) or gigabytes (GB). This can include activities such as browsing the internet, streaming videos, downloading files, and using applications. Understanding data usage is important for managing internet plans and avoiding overage charges. Many devices, including smartphones, tablets, and computers, track data usage to help users monitor their consumption. Internet service providers often offer tools or apps that provide insights into how much data is being used each month. This information can help users make informed decisions about their internet plans and data management.
