Understands and applies the mathematics of information processing
The mathematics of information processing refers to mathematical concepts and methods needed to process and use information, particularly on the Internet. For example, when making an online purchase mathematics is used to help you find what you want, encrypt your credit card number when you buy it, send your number accurately to the vendor, and, if your order is immediately downloaded as with a software purchase, make sure that your download occurs quickly and error-free.
Students should study the mathematics of information processing in order to be informed consumers and citizens in the digital age. Key themes when considering information processing are: access, security, accuracy, and efficiency. Students should understand and apply elementary set theory and logic (needed, for example, to do Internet searches), and basic number theory including modular arithmetic (at the basis of cryptography, secure e-commerce transactions, and accurate ID numbers). In addition, they should have an awareness of the need and basic concepts of data compression such as Huffman codes (as used in compression/decompression formats for online music, photos, movies, and file transfers, such as MP3, JPEG, MPEG, and .zip).
