Binary and Hex
Christiansinger on 01/19/2007 |
Way back in the dark ages of computer, we used assembler languages and looked at dumps of memory to determine problem solutions. Memory is all binary (0 & 1), so to cut down on the number of characters to be printed, and to save the eyesight and sanity of programmers, the dumps were printed in hexadecimal. Each hex digit is made from 4 binary digits. The hex digits range from 0 to 9 and A to F (which is 0 to 15 in decimal numbers) and the corresponding binary digits range from 0000 to 1111. To convert from binary to hex use the powers of 2 to determine the value of the binary digit's value. They are, from left to right 8, 4, 2, 1. For example 0010 converts to 2 in hex. And an 8 in hex converts to 1000 in binary. See if you can use this info to convert the following numbers. I will give you a hex or binary number, and you convert it to the other number system. Have fun. :-)
