A computer is an electronic device that can be programmed to automatically carry out a sequence of arithmetic or logical operations to process data and perform a wide range of tasks. It takes input, processes it according to a set of instructions (software), stores data, and produces an output.[1][2][3][4][5][6][7][8][9][10][11]
Core functions[change | change source]
- Input: Computers receive data and instructions from users or other systems.
- Processing: They perform calculations and logical operations using their central processing unit (CPU).
- Storage: They can store large amounts of data and information for later use.
- Output: They present the results of their processing to the user through devices like screens or printers.
