A computer program is a collection of instructions that performs a specific task when executed by a computer. A computer requires programs to function and typically executes the program’s instructions in a central processing unit.
A computer program is usually written by a computer programmer in a programming language. From the program in its human-readable form of source code, a compiler can derive machine code—a form consisting of instructions that the computer can directly execute. Alternatively, a computer program may be executed with the aid of an interpreter.
A part of a computer program that performs a well-defined task is known as an algorithm. A collection of computer programs,libraries, and related data are referred to as software. Computer programs may be categorized along functional lines, such as application software or system software.
Importance of Computer Programming
Computer programmers have a full understanding of the how and why of computer systems, including system limitations, and can set realistic expectations and work around those limitations to fully maximize the use of the equipment and its accessories.
Programming is a platform to showcase creativity, especially in problem-solving and entertainment. Programming develops new video games, graphics and animations to showcase new business ideas or to resolve a particular problem.
Programming, especially in web development, has allowed new interactive web applications that have access to system resources and provide the same level of control as desktop applications. Used on online learning platforms, these applications have allowed distance-learning programs to take off. Today, almost all major learning institutions have some form of online learning implementation, thanks to computer programming.
Defining The Future
Computer programming principles implemented today will likely influence how technologies such as voice-recognition, artificial intelligence and other sophisticated technologies will change in the future and how they will be applied to our day-to-day lives. For example, the trend toward automating Internet searches and purchases to be more localized is ongoing. While the hardware platforms developed will play a major role, computer technology will likely be at the center of it all and programming future systems will be an important aspect.
Since computers work with numbers, programming allows a person to represent machine-language in human-readable format. This reduces the chances of introducing errors and wasted time in debugging and correcting mistakes.
