Computation is the process of performing mathematical calculations or logical operations to solve problems or analyze data. It can be done manually or with the help of machines, such as computers. The basic unit of computation involves taking inputs, processing them according to specific rules, and producing outputs. In the context of computer science, computation is often associated with algorithms, which are step-by-step procedures for solving problems. Computers use binary code to perform computations at high speeds, enabling complex tasks like data analysis, simulations, and even artificial intelligence.
