WebThe Bitwise Complement. The bitwise complement operator, the tilde, ~, flips every bit. A useful way to remember this is that the tilde is sometimes called a twiddle, and the bitwise complement twiddles every bit: if you have a 1, it's a 0, and if you have a 0, it's a 1. 0, of course, is all 0s: 00000000 00000000.

"WebOct 23, 2024 · 1. Calculate the transfer speed by dividing the amount of data by the transfer time. Plug the amount of data (A) and transfer time (T) to solve for the rate, or speed (S), into the equation S = A ÷ T. [3] For example, you might have transferred 25 MB in 2 minutes. First, convert 2 minutes to seconds by multiplying 2 by 60, which is 120. " - Bit compression math
