A computer program, also known as a computer programme, is a set of instructions or codes written in a specific programming language that enables a computer to perform a specific task or solve a particular problem. It acts as the interface between the user and the computer hardware, allowing them to communicate and interact effectively.
Computer programs are designed using various programming languages such as C++, Java, Python, or Ruby. These instructions are written in a syntax understood by computers and can range from simple calculations to complex algorithms. They are executed by the computer's central processing unit (CPU) to perform tasks like data processing, calculations, logic operations, or control other external devices.
Computer programs can be classified into two categories: system software and application software. System software includes operating systems, compilers, and device drivers, which provide a platform for other software to run on. Application software, on the other hand, refers to programs designed for specific tasks, including word processors, web browsers, or video games.
Computer programs are developed using a well-defined set of steps known as the software development life cycle (SDLC). This includes requirements gathering, design, coding, testing, and maintenance. Once a program is created, it can be distributed and installed on multiple computers, allowing users to run the same program and achieve consistency in their tasks.
Overall, computer programs are the building blocks of modern technology, enabling computers to perform a wide range of functions and tasks efficiently.
