When you assignment with computers you see KB (or KiloBytes) and MB (or MegaBytes) all the time but what does it angle for? Basically it’s a altitude of anamnesis on a computer. To advice you accept absolutely what in agency there is an archetype below.

So What’s a Byte anyway?

When you get appropriate bottomward to it computers alone apperceive two things off and on. That’s it aloof OFF and ON. And a computer expresses OFF as a “0” and ON as a “1”. Everything you see on the awning appropriate now is aloof a accurately ordered aggregate of 1’s and 0’s to the computer that acquaint it absolutely how to affectation this webpage. Now here’s the ambagious part. Each alone 1 or 0 is alleged a BIT and 8 BITS calm is alleged a BYTE. When you blazon a 0 the computer absolutely recognizes that aught as the alternation of 8 BITS or “00000000”

Here are some examples of what some added numbers and belletrist attending like to the computer:

                                             0 = 00000000 a = 01100001 L = 01001100

                                             1 = 00000001 v = 01110110 p = 01110000

                                             2 = 00000010 $ = 00100100 z = 01111010
