Bits vs Bytes

1 Byte = 8 bits. Internet speeds are measured in bits (Mbps), while file sizes are in bytes (MB).

100 Mbps internet = 12.5 MB/s maximum download speed

ISPs advertise in Mbps (megabits) because the numbers are larger. Divide by 8 to get MB/s (megabytes).

Note: Actual speeds are often lower due to network overhead, congestion, and other factors.
