Why do we need different coding languages?

In summary, we have a variety of programming languages because there is a variety of jobs to be done and a variety of people who do those jobs. This diversity makes interesting programs – and interesting companies, and interesting careers – possible.

What is the rationale for having lots of different levels of languages in a computer?

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.

Are all programming languages Turing-complete?

Turing completeness is used as a way to express the power of such a data-manipulation rule set. Virtually all programming languages today are Turing-complete. The concept is named after English mathematician and computer scientist Alan Turing.

Are all coding languages similar?

Yes, programming languages are similar, but not that much. The basics of every programming languages are pretty much the same, but the way you write and use those basics to solve problems differs a lot for every programming language.

Why are high level languages machine independent?

Writing programs in binary is complex and cumbersome process. High level programs require compilers/interpreters to translate source code to machine language. We can compile the source code written in high level language to multiple machine languages. Thus, they are machine independent language.

Why is Turing-complete important?

Turing completeness, named after Alan Turing, is significant in that every plausible design for a computing device so far advanced can be emulated by a universal Turing machine — an observation that has become known as the Church-Turing thesis.

What does a language need to be Turing-complete?

In computability theory, a system of data-manipulation rules (such as a computer’s instruction set, a programming language, or a cellular automaton) is said to be Turing-complete or computationally universal if it can be used to simulate any Turing machine. Virtually all programming languages today are Turing-complete.
