Why octal and hexadecimal numbers use extensively by computers' specialists?
Hexadecimal numbers are used in MAC addresses (hardware addresses) in computers. This gives an unlimited number of possible combinations to computer manufacturers. That way each PC in the world has a unique identifier. Esuka Endeley Hexadecimal is a number system using Base 16. It uses the digits from 0 to 9 and the letters from A to F, A=10, B=11, C=12, D=13, E=14, F=15. It enables very large numbers to be written with fewer characters. As computers have very large memories, addressing specific parts of them becomes a big task. Hexadecimal is used as a way of doing so. Sometimes if your computer crashes you will see an error message showing a number with letters in it. Those letters are always between A and F. Basically what it is saying is that there was a problem in memory at this point. Hexadecimal is used in many other ways in computers. One very common purpose is for colour codes in web pages. 6 digits are used, with 2 representing the amount of Red, 2 the amount of Green and 2 for the amount of blue. So if you want a lot of Red, but not much blue or green as a mix for your colour, the code could be something like FF0502. FF represents 255. If you do a web design course, specifically learning to use HTML for creating colours on your pages, you will learn more about this.
7 Why is binary code suitable for use with computers?
Binary is well suited for computers because it only needs two symbols to represent numbers a 1 and a 0. In a computer a circuit can be in 2 states on and off hence in the simplest implementation"on" represents a 1 and "off" a 0.
Who uses binary code?
Binary Codes (0s & 1s) are ways that represent how signals are interpreted on Storage devices. Therefore Binary codes are different for various types of Media available. i.e. Magnetic Orientations (North or South Pole) represents binaries on Magnetic Platter based HDDs Pits & Lands represents binaries on Optical Media (CDs & DVDs)
