FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Assembly language uses a mnemonic to represent, e.g., each low-level machine instruction or opcode, each directive, typically also each architectural register, flag, etc. Some of the mnemonics may be built in and some user defined.

Detailed explanation-2: -Mnemonics are the names for the symbols used in assembly language. A phrase, symbol, or word used to define or identify a computing function is known as a mnemonic.

Detailed explanation-3: -Assembly language uses symbols to represent binary codes of machine-level instructions. The symbols (mnemonics) in Assembly Language are used to represent binary codes that are used in machine language (the most fundamental form of programming languages).

Detailed explanation-4: -The assembler language is the symbolic programming language that lies closest to the machine language in form and content. The assembler language is useful when: You need to control your program closely, down to the byte and even the bit level.

Detailed explanation-5: -The C programming language is often called “portable assembly” because C compilers exist for nearly every modern system architecture. A program written in C may require some changes before it will compile on another computer, but the core language is portable.
