Computer Measurement Unit summary kmg369

When buying a hard disk, such as 160 GB, the manufacturer uses 1000 in hexadecimal format,
Instead of 1024, the 160 GB format will only be:
(160x1000x1000x1000)/1024/1024/1024 = 149 GB

GB = gigabyte, a type of computer storage unit, 1 GB = 1024 MB, 1 TB = 1024 GB
GB = Gigabit, Gigabit, 1 GB = 30 times of 2 Orientation = 1024*1024*1024 = 1 073 741 824

How can the network crash with a stomachache?
The bitmap is used to implement the train ticket booking system. Assume that there are 5000 trains every day, each of which has 5000 seats, and each has 100 stops,
Use a bit to identify whether the seat has been booked. You only need 5000*5000*100 <2.5G bit, less than 1G bytes.

1 byte equals 8-bit binary 2.5G bit = 0.3125 GB
