bulletNumeric Conversions: This website basically just explains how to do numeric conversions. It provides some fundamental concepts and gives step-by-step examples of how to convert between the different numeric systems used in computers. Also, has a section containing “Neat Tricks” to convert from binary, octal and hex. Overall, this page provides a very down to earth explanation of how numeric systems work.
bulletNumeric Conversions in Computing: This website helps explain the basic concept of numeric conversion in an easy to follow process by converting from binary, octal and hexadecimal, (in sort called hex). It also gives a brief explanation on why numbers are aligned a certain way.
bulletIt goes over the basic information concerning the different numbering systems. I found it helpful as a source of information because it went over what we learned in class, so it was a good page to review what I learned.

bulletBinary Numbers: The topic I selected to research for Basic Data Types was information on binary, decimal, hexadecimal and octal numbers. First it began to explain that the computer operates by using binary logic. The stages 1or 0 represent the two levels of voltage. To distinguish between binary, decimal, hex and octal you use a subscript. Four binary bits are used to correspond to a hexadecimal digit. It continues to show how the binary number is represented by hexadecimal. An example would be the binary number 0111 turns out to be 7 in hexadecimal. When it comes to converting binary to octal, three binary bits represent an octal digit. The octal digit 4 is equal to 100 in binary. Next, to convert a decimal number to binary you would divide the number by 2 and get the remainder. The example given was converting 45 to binary digits which are 101101. I thought this website was very informative. It was a good review on converting to decimal, hex, octal and binary especially before the quiz. I recommend this site because it shows you several examples as well as a brief explanation on each topic

bulletThis website further illustrates what we've covered in class pertaining to the hexadecimal system. The site provides an abundant amount of information concerning hex conversions (hex to binary, binary to hex, hex to decimal, decimal to hex) and a brief summary about hexadecimal. My only complaint about this website is that doesn't essentially describe what the hexadecimal is. I recommend this website to anyone who is having problems converting from one numbering system to another. That is the basis of this site (converting). There is an excellent source of links at the bottom of the page that provides users with reference to Bits and Bytes, ASCII Code (chart), and the Octal Number System just to name a few.

bulletThis site is really good because it shows you various examples on how to convert any base to decimal. In addition, it shows all the tables that we went over in class, like the octal and hexadecimal table. I enjoyed this site because it gives you a step by step representaion on how to do these types of problems.

bulletThis website has a calculator that allows you to convert between bits and bytes. Its very simple to use all you do is fill in the bits blank and the calculator will convert to bytes, Kb, KB, Mb, MB amongst others. It also provides a link to a quick reference on bits and bytes in case you need some information on them.

bulletCool site with a chart and converter for HEX, OCTAL, DEC. and ASCII characters: This is a cool website that has a cool chart that helps to convert from hex, to decimal, to octal, to the character. There is also a cool interactive converter where you put either ASCII, HEX, OCTAL, or DEC. and it gives the others.

bulletPurlplemath - Your Algebra Resource; Number Bases III: This website has a step by step format. It teaches you how to convert from octal to decimal to hexadecimal and vice versa. It also has the 'Now YOU Try It' Link, where you can practice on problems. This site is very easy to follow.
