Computer programming or coding is the composition of sequences of instructions, called programs, that computers can follow to perform tasks. [1] [2] It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing code in one or more programming languages.
Computer science is also notorious for being a very difficult subject in schools, with high failure and dropout rates over the years it has been taught. [22] This is usually attributed to the fact that computer science as a subject is very problem-solving heavy and a lot of students can struggle with this aspect.
This enables an application to be run on different hardware without needing to be rewritten. [12] Application software runs on top of the operating system and uses the computer's resources to perform a task. [13] There are many different types of application software because the range of tasks that can be performed with modern computers is so ...
