Digital computers are electronic devices that process data using binary code, which consists of zeros and ones. They perform calculations and execute instructions through a series of logical operations. Digital computers are widely used in various applications, including personal computing, data analysis, and software development. These computers consist of hardware components, such as the central processing unit (CPU), memory, and storage devices. They run on software programs that provide instructions for tasks, enabling users to perform activities like browsing the internet, creating documents, and playing games. Digital computers have revolutionized how we work and communicate in the modern world.
