What is the importance of computer system architecture? next (unless that sequence is explicitly modified with loops and jumps). But an even more efficient way would be opening the phone book to the middle, decide whether Mike will be in the left half or right half of the book (because the book is alphabetized), and immediately throw away half of the problem. We can even put a number of times into our cough function, so we only need a single block to cough any number of times: We look at some examples and discuss how we might implement components of them with different sprites that follow the mouse cursor, or cause something else to happen on the stage. 9 0 obj endobj that we can see and touch are the hardware components of a computer.
