Assigment 10: Binary Part 2

Binary ASCII

American Standard Code for Information Interchange (ASCII), pronounced /ˈæski/^[1] is a character-encoding scheme based on the English alphabet. ASCII codes represent text in computers, communications equipment, and other devices that work with text. Most modern character-encoding schemes—which support many more characters than did the original—have a historical basis in ASCII.

Historically, ASCII developed from telegraphic codes. Its first commercial use was as a seven-bit teleprinter code promoted by Bell data services. Work on ASCII formally began October 6, 1960, with the first meeting of the American Standards Association’s (ASA) X3.2 subcommittee. The first edition of the standard was published in 1963,^[2][3] a major revision in 1967,^[4] and the most recent update in 1986.^[5] Compared to earlier telegraph codes, the proposed Bell code and ASCII were both ordered for more convenient sorting (i.e., alphabetization) of lists, and added features for devices other than teleprinters.

ASCII includes definitions for 128 characters: 33 are non-printing, mostly-obsolete control characters that affect how text is processed;^[6] 94 are printable characters, and the space is considered an invisible graphic.^[7] The ASCII character-encoding scheme is the most-commonly-used character set on the Internet.^[8];l

^{Converting Hexadecimal to base 10}

To convert a number from base 16 to base 10, you read it like this:

43 in base 16 = 4 X 16¹ + 3 X 16⁰ = 64 + 3 = 67 in base 10.

Do the steps in this order

1. raise the base to the power
2. multiply the result by the place value
3. add the result for each place

Remember that letters just stand for numbers between 10 and 15.
