What is the difference between assembler and assembly language?
When used as nouns, assembler means a program that reads source code written in assembly language and produces executable machine code, possibly together with information needed by linkers, debuggers and other tools, whereas assembly language means a programming language in which the source code of programs is composed …
What is the relationship between assembly language and machine language?
Assembly language is a low-level programming language . It equates to machine code but is more readable. It can be directly translated into machine code, but it uses mnemonics to represent the instructions to make it easier to understand.
What is the difference between program code and machine code?
This executable code is known as machine code. Hence the main difference between both of these is that the source code is programming language specific code which is non-executable but standardized to be converted whereas the machine code is the actual executable code.
Why is it called bytecode?
The name bytecode stems from instruction sets that have one-byte opcodes followed by optional parameters. Bytecode may often be either directly executed on a virtual machine (a p-code machine i.e., interpreter), or it may be further compiled into machine code for better performance.
What is an example of assembly language?
Typical examples of large assembly language programs from this time are IBM PC DOS operating systems, the Turbo Pascal compiler and early applications such as the spreadsheet program Lotus 1-2-3.
Why would you use assembly language?
Today, assembly language is used primarily for direct hardware manipulation, access to specialized processor instructions, or to address critical performance issues. Typical uses are device drivers, low-level embedded systems, and real-time systems.
What is Python high-level language?
In software engineering world, Python is understood as a high-level, interpreted general-purpose language. This means it is not your straight compiled language (like Java or C) but an interpreted dynamic language that has to be run in the given system using another program instead of its local processor.
