Computational Systems

The computation systems can be defined as the systems that are capable of solving a problem that includes calculations either mathematical or logical, and are able to produce the result as an output. For example, a simple calculator that is given a set of numbers and operators as input and produces the result as an output can be defined as a computational system. The above example is a simple illustration only, the computational systems range from simple devices to complex devices such as the systems that control the SpaceX companies, Starlink satellites which are being quite recently seen in the skies at many places globally.

A quaker was walking down a country road when he was suddenly confronted by a robber brandishing a pistol. The robber exclaimed, "Your money or your life!" My friend replied, "I cannot deliver my money because I should be aiding thee in evildoing, but exchange is lawful, and I will give thee my purse for the pistol." The thief consented to accept the purse, then the quaker pointed the gun to the robber's head and said, "Now buddy, give me back my pocketbook or the weapon may go off fire," according to the robber.
Today we learned how to build truth tables in order to understand our symbolic statements better. Build a truth table (that's right, the entire truth table) for the following statements: 1. ~ B ∨ X2. A • ~ Z 3. ~ X ⊃ ~ C 5. ~ (C ∨ (X • ~ Y)) 6. (X ⊃ ~ A) ⊃ (~ Z • B) 7. ~ (A ∨ ~ X) ∨ (C • ~ Y) 11. ~ X ∨ (Q ⊃ Z) 12. ~ Q • (A ⊃ (P • ~ B)) 13. ~ (Q • ~ Z) ⊃ (~ P ⊃ C) 15. ~ P ∨ (Q ∨ P)
A pistol-wielding robber approached a Quaker on a rural road. "Your money or your life!" shouted the thief. "Exchange is allowed, and I will offer thee my purse for the weapon," my buddy said. The thief accepted the handbag, then the quaker held the pistol to his head and said, "Now friend, give me back my pocketbook or the weapon may go off fire," according to the robber.
