Software is a set of instructions, data, or programs used to run a computer and perform tasks. In simple terms, it tells a computer how it should work. A common term used to refer to applications, texts, and applications running on devices such as PCs, cell phones, tablets, and other smart devices. It is a anti-hardware, which is the physical interface of the computer that does the job.
Without software, most computers would be useless. For example, a web browser is a software program that allows users to access the Internet. Without web browser software, reading this page on Web would not have been possible. An operating system (OS) is a software program that acts as a visual interface between other applications and hardware or mobile device. TCP / IP is build into all major applications to allow computers to communicate over long distance networks. Without OS or built-in protocols, you will not be able to access the web browser.
We wrote most of the software in advanced programming languages due to its close proximity to the native human language as opposed to machine language. The high-level language is translated into a low-level machine code using a compiler or translator for the computer to understand. We may also write software in low-level integration language, but it is less common.
