Consider two internet service options priced the same:
one offers 1 gigabit (1 Gb/s) and the
other offers 250 megabytes per second (250 MB/s). Which option is a
better deal?
1Gb = 1,000,000,000 bits
250MB = 250,000,000 * 8 = 2,000,000,000 bits.
Therefore 250MB is the better option as it is provides double bps speeds for the same price
