Question
This is a learning exercise question, not a quiz! You can do this exercise as many times as you like, to increase your understanding and to raise your grade. Statements are shuffled in sequence every time you do the exercise. Place a checkmark in the box front of any statement that is true Don't place a checkmark in front of a statement if the statement is false Keep notes of how you answer each question. 0, 1, 2 or 3 statements may be false within a single question. You get partial credit for correct answers but any incorrect checkmarking wipes out some credit for the whole question!. Bottom line: Getting loss than full credit means that you have a gap in your knowledge that you need to overcome by reviewing the pages of "Learn About Computers'' shown after each statement. If you get less than 15 points (100%) for this question, review the readings or viewings covered by this question. Select one or more In some written human languages a given symbol stands for a thing, not a letter. Signals can be used to communicate because everyone has agreed, ahead of time, what the signals mean. With two off/on conditions we can represent 4 different situations. With three objects that can be in one of two 'states' we can represent a maximum of 2 + 2 + 2 = 6 different conditions. Computers would rot do us any good if we could not communicate information to them and receive information back from them. We need to represent about 90 different characters to be able to convey an English- language message using some form of code. 'Event/meaning' communication cant deal with messages that are needed for unexpected conditions. If we used four m&m;'s each of which could be one of two colors, we could represent a total of 2 times 2 times 2 times 2) = 16 different messages or characters. With ASCII code expressed conditions.

With ASCII code expressed in 8 different bnary ob;ects we can express at most 128 different characters which is far more than needed to be able to convey a message in English. Signaling is actually the communication of a message from one place to another without the use of human speech.
