Welcome to Week 9
In this module, we will continue to learn about computer basics, like software. Last week, we discovered that computer hardware consist of all of the physical parts of a computer. We also talked about how computers take in information from the keyboard. The information is then processed through the computer processor, which can do millions of calculations per second. After the information is processed, it is sent to output devices, like the computer monitor in the form of useful information. This information can be in the form of a report, graphs, video, or a picture.

It is important to understand that computers communicate and process information in the form of binary code, which is 0's and 1's. A bit is composed of a number, which is either 1 or 0 (Pearson, 2017). "A byte is a string of 8 bits"( Pearson, 2017). An example of a byte is 00101101. A byte can represent a letter, symbol or a number.

When you think of a picture, it is hard to imagine that a picture is composed of millions of pixels. Each pixel is a tiny square with a shade of color. Together, the millions of pixels can create an image, or video output. A single pixel is made up of a 3 byte combination. Each byte represents a color. For example, the first byte can represent 256 shades of red, the second byte can represent 256 shades of green, and, lastly, the last byte can represent 256 shades of blue. Together, these bytes can create any color. Today's phones can take pictures of at least 10 mega pixels, which means 10 million pixels are in an image. In order to process this information, the Central Processing Unit or CPU must be capable of calculating millions if not billions of calculations a second. Think of the amount calculations needed for video output, for example.

Software, on the other hand, are programs that a computer runs. The programs essentially tell a computer "what to do and how to do it." (Pearson, 2017). Two types of programs exist in the computing world. They are system software, which is the operating system that a computer runs. For most computers, this is Windows or Macintosh OS. These are the programs that run in the background and allow computers to "run and work properly" (Pearson, 2017).

Examples of application software are Microsoft Word, Power Point, Excel, and Database. These programs allow you to write reports, do calculations, or keep track of important information. Other computer programs are useful for playing games, listening to music, or watching movies. For example, think of Netflix, Apple Arcade, or Apple Music. These are all computer programs that allow the user to perform a specific task.
