As you can imagine, the cumbersome process of switching from floppy to floppy prompted the birth of the operating system. An operating system is a software program that controls how the computer's hardware (and installed software) works. It manages the activity of every component and then displays that activity as a user-friendly interface (GUI). The keyboard and mouse controls give users the option of speeding up or slowing down the movements of both of these peripherals. For those entering the United States from a foreign country, users will appreciate how Windows grants use of keyboard layouts native to their original language. Other uses will appreciate the different selection of cursors and the ability to add additional ones. Sure, one could upgrade the operating system to accommodate the demands of a new piece of hardware, but trouble starts when that new operating system requires new hardware in return. If we're not careful, we could end up replacing almost every hard and soft part of a computer that we own - all in an effort to upgrade!

Input box - input boxes are usually small rectangles that allow you to type data into a simple interfaces like a webpage or browser window. The data that a program receives is called input and data that the program generates is called output. Other times, the data is unknown. If the program were working with a simple algebra equation like, "x + 5 = y," the variables "x" and "y" would be unknown pieces of data.
