1. Computer - come in many shapes and sizes. Simply put, computers process data. With that broad definition, your phone is a computer, your tablet (for example, an iPad) is a computer, and so is your MP3 player, your video game system, and your modern digital television. There are a many kinds of devices. 2. Bit - A bit is the smallest unit of data that a computer works with. However, just like humans use multidigit decimal numbers every day, computers work with multidigit binary numbers. 3. Byte - is a unit of digital information that most commonly consists of eight bits 4. Random Access Memory- RAM physically exists as a set of microchips installed on a plastic card called a memory module. The chips and the electronics on the card together create a set of physical locations in which a computer can store and read bits or bytes of data. 5. Character Set - , sometimes called a character encoding scheme, lists all the text characters on the computer with a matching binary value. When the user types one character, the computer CPU looks at the character set and stores the matching (mapped) binary value. interprets user actions and convert those actions into bits. Focus for a moment on what happens starting with the point in which the word processor was ready for the user to type a brand new document. For each letter pressed on the keyboard, hidden to the user, the keyboard sends some bits to the computer, specifically to the CPU. Again hidden, the CPU processes the bits that arrive from the keyboard; the CPU stores those bits in RAM. Additionally, the CPU updates some other bits that represent what the computer displays on the screen and sends the new image (again represented by bits) to the screen. 6. Input and output – the input part refers to creating information in the computer. Some actions involve the user, and some do not. For
