- Do you see yourself using email in the not-too-distant future? The path of an email message starts with the sender and concludes with the receiver of the message. Take careful notes on everything you discover. Is there a rationale to the differences, and if so, what are they? Consider the possibility that there exist several models, each of which has a unique level of complexity (or abstraction).arrow_forwardFrom the truth table for A ∨ B, the value of A ∨ B is true if A is true, if B is true, or if both are true. This use of the word “or,” where the result is true if both components are true, is called the inclusive or. It is the inclusive or that is understood in the sentence, “We may have rain or drizzle tomorrow,” which might also be expressed as, “We may have rain or drizzle or both tomorrow.” Another use of the word “or” in the English language is the exclusive or, sometimes written XOR, in which the result is false when both components are true. The exclusive or is understood in the sentence, “At the intersection, you should turn north or south,” (but obviously not both). Exclusive or is symbolized by A ⊕ B. Write the truth table for the exclusive or.arrow_forwardDetermine whether or not the following statement is a tautology or not and give reasoning. If you need to, you can build a truth table to answer this question. (q→p)∨(∼q→∼p) A. This is a tautology because it is always true for all truth values of p and q. B. This is not a tautology because it is always false for all truth values of p and q. C. This is a tautology because it is not always false for all values of p and q. D. This is not a tautology becasue it is not always true for all truth values of p and q.arrow_forward
