List of Measurable Verbs Used to Assess Learning Outcomes. Bloom's Taxonomy of Educational Objectives (1956): Cognitive Skills. A group of educators, led by Benjamin Bloom, identified a hierarchy of six categories of cognitive skills: knowledge, comprehension, application, analysis, synthesis and evaluation.
In normal maths, we don't use binary. We were taught to use our normal number system. Binary is much easier to do math in than normal numbers because you only are using two symbols - 1 and 0 instead of ten symbols - 0, 1, 2, 3, 4, 5, 6, 7, 8, and 9. Computers use binary because they can only read and store an on or off charge. So, using 0 as off and 1 as on, we can use numbers in electrical wiring.
Since computers (or central processing units, to be specific) use machine language in the form of numbers to communicate, computer programmers need to write their instructions using numbers rather than alphabet characters. To do this, programmers use numeric representations of what humans see as alphabet characters. You've probably seen or heard of binary code which uses only 0s and 1s to represent an alphanumeric character. Computer programmers can use a series of 0s and 1s to represent any character they wish.
