- Pg 4Objective 1-1.1.1Briefly discuss how computers are so much a part of our lives that we often don’t think about them as computers. Use examples of different types of computers when you go over the last point and relate it to the first point, e.g., microwaves, game systems, iPhones, Blackberries, ultrasound equipment, etc.You may want to give examples of when or why a company may have a combination of large and small computers such as a financial institution who has a mainframe for historical information and yet each employee has a personal computer or microcomputer at their desk to help customers. These computers can be in any location and connect to a server that accesses data from the mainframe.
