Transistors - The computer contains millions of transistors, which are used to create machine language using logic gates that turn on and off the circuits. Machine language - All computers and electronic devices communicate in binary, which is a series of 0's and 1's or Off and On electrical signals. All software written on your computer is created in a high-level programming language that humans can understand, when complete the program is compiled into the machine language that computers understand

are some completely necessary I/O devices that you’ll need. First would be a keyboard, this is how you manually put information into your computer. Next would be a way for you to move the pointer on your screen, whether it be a mouse, touchscreen, or mouse pad. In order to either put sound into your computer or get sound back from it you would need both a microphone and speakers. A sound card to get sound out through the speakers. One of the most important devices you would need would be the monitor
