Document Summary

But it could also be a 8 digit number as follows: If you had to represent the numbers with digit holders, you pad the front with zeros. How does a computer represent numbers and words and images and. Sound: zeroes and ones on a computer represents everything from numbers, words, images and sound, called binary. If we have 1 bit 0, 1. Use 1 byte for each letter . Thus dog would be encoded as: 0100100, 01001111, 01000111. With 8 bits, (or 1 byte), we can encode 28 256 different characters. Binary (2 binary digits/ bits) 0,1,10,11,1(cid:882)(cid:882),(cid:883)(cid:882)(cid:883), (cid:883)(cid:883)(cid:882), (cid:883)(cid:883)(cid:883),(cid:883)(cid:882)(cid:882)(cid:882), (cid:883)(cid:882)(cid:882)(cid:883), . 13,14,15,16,17,18,19,(cid:883)a,(cid:883)b,(cid:883)c,(cid:883)d,(cid:883)e,(cid:883)f,(cid:884)(cid:882) fa, fb, fc, fd, fe, ff, (cid:883)(cid:882)(cid:882), (cid:883)(cid:882)(cid:883), (cid:883)(cid:882)(cid:884), . Note: as soon as you run out of patterns, you need an extra place holder (just like you learned in grade 2, that in decimal, when you have the numbers from.
