Computer
A computer is an electronic device that processes data and performs various tasks according to a set of instructions known as programs. It consists of hardware components, such as the central processing unit (CPU), memory, storage devices, and input/output peripherals, which work together to execute operations efficiently. Computers are capable of performing a wide range of functions, from simple calculations to complex simulations and data analysis. They have revolutionized nearly every aspect of modern life, impacting fields such as education, business, healthcare, and entertainment. With the advent of the internet, computers have become essential tools for communication and information sharing, enabling people to connect globally and access vast amounts of knowledge at their fingertips. As technology continues to evolve, computers are becoming increasingly powerful and versatile, paving the way for innovations in artificial intelligence, machine learning, and beyond.
