ADSL's network card indicates that the bandwidth is 1MB, which means that the maximum traffic you can get per second is 1MB data! This bit is the smallest unit of computer bit, that is, a binary number 0 or 1, but the unit of quantity we usually use is "byte", which is equal to 8 bits, that is to say, the actual maximum download speed of dial-up bandwidth of 1 megabyte is 1 MB/8 = 65438.

If you download 700M content at this speed, it takes 700M/ 128KBs=5600s, which is about 93.33 minutes!

Of course, in reality, it can't always be 128kB, which is lower on average. This number is the download speed displayed by the commonly used download tool Thunder!

Finally, the power of 2 10 is 1KB 2, and the power of 20 is 1MB. This is a byte!

Note that b is capitalized, and it is said in bytes. If b is lowercase, it is bit!

I hope it will help the landlord.
