FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -For the purpose of clarity “source code” is taken to mean any fully executable description of a software system. It is therefore so construed as to include machine code, very high level languages and executable graphical representations of systems.

Detailed explanation-2: -A high-level language is a programming language that uses English and mathematical symbols in its instructions. To execute a program in a high-level language, it can be compiled or interpreted. A compiler translates the entire program written in a high-level language to machine language prior to execution.

Detailed explanation-3: -High-level languages are designed to be used by the human operator or the programmer. They are referred to as “closer to humans.” In other words, their programming style and context is easier to learn and implement than low-level languages, and the entire code generally focuses on the specific program to be created.

Detailed explanation-4: -Programmers write in high-level languages because they are easier to understand and are less complex than machine code. They allow the programmer to focus on what needs to be done, rather than on how the computer actually works.
