Computers: Arguably the Greatest Invention of All Time.
For the past 20 years I have been fascinated with technology, specifically computers. Computers are a part of our everyday lives and most don’t realize this technology makes the world go round. I would venture to say that computers have contributed to our lives more so than Gutenberg's printing press. Take a quick inventory of the things you own, your cell phone, microwave, television, printer, car, and IPod. These electronics all have a computer that allows them to function properly and make your life easier or more enjoyable. Let’s learn together how computers have revolutionized our life as we know it. Not everyone may know what a computer is so I will give a brief summary of what exactly it is and its purpose. A computer is a general purpose device that can be programmed to carry out a finite set of arithmetic or logical operations. Since a sequence of operations can be readily changed, the computer can solve more than one kind of problem. Conventionally, a computer consists of at least one processing element, typically a central processing unit (CPU) and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit that can change the order of operations based on stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved. In other words a computer is a device that is designed to do what we tell it to do. We give it commands that are mathematically calculated in a code called binary code. A Binary code is a way of representing text or computer processor instructions by the use of the binary number system's two-binary digits 0 and 1. This is accomplished by assigning a bit string to each particular symbol or instruction. For example, abinary string of eight binary digits (bits) can represent any of 255 possible values and can...
