Why are computer programs written in high-level?
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 high-level languages more efficient?
In many cases, critical portions of a program mostly in a high-level language can be hand-coded in assembly language, leading to a much faster, more efficient, or simply reliably functioning optimised program.
Can you make an OS with python?
No, one cannot write an operation system in python. In very simple terms, operating system is a software that manages the hardware resources of the computer. Hence, it needs to run directly on top of the hardware without anything in between, this is called running bare metal.
Why is it easier to write a program in a high-level language than in machine language?
Are there any high level operating systems written in C++?
If you consider C++ to be high-level, then there is at least one OS written entirely in a high-level language (Symbian OS is written in C++). What stops you from writing an OS in most high-level languages are two things:
What programming language should I learn to write an operating system?
High-level programming languages work with multiple computer architectures. C is the programming language most commonly used and recommended for writing operating systems. For this reason, we are going to recommend learning and using C for OS development. However, other languages such as C++ and Python can also be used.
What stops you from writing an OS in a high-level language?
What stops you from writing an OS in most high-level languages are two things: An OS needs low-level access to memory and hardware and perform dirty tricks on them. This kind of access is generally considered unsafe for application-level programs, so many high-level languages don’t allow it.
Why is it so hard to write an operating system?
An OS needs to execute without support software being present, such as interpreters. This makes it extremely hard to write an OS in a language that can’t easily be compiled into native instructions. There are a number of good reasons for this. Yes, believe it or not, once upon a time even C was viewed as a high-level language.
