UNIT–I : Introduction to Computers

Computer System (≈150 words)

A computer system is an integrated set of components that work together to process data and produce useful information. It includes hardware, software, data, procedures, and users. Hardware refers to physical devices like keyboard, mouse, CPU, and monitor. Software provides instructions that tell the hardware what to do. Data is the raw facts entered into the system, while procedures are the rules for operating the computer. Users are the people who use the system. A computer system follows the Input–Process–Output (IPO) cycle. It accepts input, processes it using instructions, stores data if needed, and gives output. Computer systems are widely used in education, business, banking, research, and government offices. They increase speed, accuracy, and efficiency in work and help in decision-making and problem-solving.
