Transistor meaning in computer9/1/2023 But in binary, you read the numbers like a math equation. In the decimal system, you read all the numbers together at once as a whole number¬-1, 10, 100. Reading binary numbers is different than reading decimal numbers. If you see a number written as 100 10, the little 10 tells you that the set of numbers is in base 10, or decimal. When you see a number written as 100 2, the little 2 lets you know the set of numbers is in base 2, or binary. In math, a little subscript number is added to the right-most number in a set to tell you what base system the number set is in. So, if you saw the number 100, how would you know if it was in base 2 or base 10? The decimal system is a base 10 number system. Its name also tells you how many digits it includes, as dec comes from the Latin prefix meaning ten. The 2 represents the number of digits the system uses.Ĭompare this to the decimal number system you use. In fact, the bi in binary comes from the Latin prefix meaning two. The binary number system, which computers use to store and process information, only uses two digits: 0 and 1. Try lesson 1: Work and play with pictures. In these activities, the squares are much bigger than the real thing, but doing this activity will show you how an image can be portrayed with just two instructions: on and off. Computers operate by mixing these three colors to create black, white, and millions of other color combinations.įor your next activity, think of the grid as a simplified view of a black-and-white computer screen. That’s 921,600 total pixels!Įach of these pixels display some combination of red, green, and blue to create colors. For example, a high-definition 1280 x 720p resolution screen means the screen would have a width of 1,280 pixels and a length of 720 pixels. The higher the pixel count, the higher the resolution, and the better the picture quality. Each dot is a piece of a picture-otherwise known as a pixel-and the number of pixels used is called the resolution. Your computer screen has hundreds of thousands, if not millions, of dots arranged in rows and columns. Imagine a computer that is made up of billions of electronic switches (transistors).
