what is a computer +8 What is a Computer? an introduction - W3Scoop A computer is an electronic device that takes in data (input), processes it using stored instructions, produces results (output), and saves information for later use, functioning as a programmable machine for calculations and a wide range of tasks. It works with binary code (0s and 1s) to perform logical and arithmetic operations, transforming from a tool for scientists into everyday objects like desktops, laptops, tablets, and even smartphones. Core Functions Input: Accepts data through keyboards, mice, touchscreens, etc.. Processing: Follows instructions (programs) to manipulate data. Output: Shows results via screens, speakers, printers, etc.. Storage: Saves data and programs for future access. Key Characteristics Programmable: Can be told to perform different tasks by loading different software (programs). Electronic: Uses electrical signals, often represented as binary (1s and 0s). Versatile: From complex calculations (like supercomputers) to browsing the internet (like your phone).
