What is an algorithm primarily used for?

An algorithm is fundamentally a step-by-step procedure or formula for solving a problem or performing a task. It is primarily used for executing computations, processing data, and establishing logic to arrive at solutions for specific computing problems. Algorithms are the backbone of programming and software development, as they define the operations and sequences required to perform calculations, sort data, search through information, or automate processes.

While tasks related to designing user interfaces, storing data, or creating documentation are significant components of software development, they do not fundamentally define an algorithm's main purpose. Algorithms themselves specifically focus on systematic methods for problem-solving within the realm of computation, enabling machines to process information effectively and efficiently.
