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: -The Assembler is a Software that converts an assembly language code to machine code. It takes basic Computer commands and converts them into Binary Code that Computer’s Processor can use to perform its Basic Operations. These instructions are assembler language or assembly language.

Detailed explanation-3: -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. Assembly language enables programmers to write code that corresponds to the machine instructions that a given processor may execute.

Detailed explanation-4: -"LDA” is the mnemonic for the opcode (load accumulator A) and “21” is the operand (an address given in base 10). The manner of specification of the target address is called the addressing mode of the machine language instruction. A program for translating assembly language programs is called an. assembler.

Detailed explanation-5: -Assembly Language Uses Mnemonic Codes or Symbols instead of binary numbers. The only language directly understood by a computer.
