Your internet speed is based on how long your internet connection can download and upload data (bits). This speed is measured in megabits per second (Mbps) and gigabits per second (Gbps) — one Mbps is 1,000,000 bits being transferred per second, and one Gbps is 1,000,000,000 bits being transferred per second. The higher the Mbps or Gbps you see, the faster the internet speed. Just remember that your chosen speed will depend on your specific internet needs.
