difference between machine language and assembly language

Assembly language may also be called symbolic machine code. Assembly language is converted into executable machine code by a utility program referred to as an assembler.
These set of instructions are called 'machine language instructions'. A processor understands only machine language instructions, which are strings of 1's and 0's. However, machine language is too obscure and complex for using in software development. So, the low-level assembly language is designed for a specific

Machine code or machine language is a set of instructions executed directly by a computer's central processing unit (CPU). Each instruction performs a very specific task, such as a load, a jump, or an ALU operation on a unit of data in a CPU register or memory. Every program directly executed by a CPU is made up of a
Mnemonics. Assembly language instructions use abbreviations called mnemonics. An example of a mnemonic assembly language instruction is LDA 50 which stores the value 50 into a register of the CPU. Mnemonics are easier for humans to remember and understand than binary machine code instructions. The following
Programs written in assembly language are usually made of instructions, which are small tasks that the computer performs when it is running the program. They are called instructions because the programmer uses them to instruct the computer what to do.
The instruction pointer is called ip in 16-bit mode, eip in 32-bit mode, and rip in 64-bit mode. The instruction pointer register points to the memory address which the processor will next attempt to execute; it cannot be directly accessed in 16-bit or 32-bit mode, but a
These instructions are conditional jumps that are based on the status of a set of condition codes that are stored in a special register called the machine status word. The contents of the machine status word include information about the last arithmetic operation performed. For example, one bit of
The language to command a computer architecture is comprised of instructions and the vocabulary of that language is called the instruction set. The only way computers can rep- resent information is based on high or low electric signals, i.e., transistors (electric switches) being turned on or off. Being limited to those 2
The translation program is called an assembler (in this case the LC-3b assembler), and the translation process is called assembly. 7.1.1 Instructions. Instead of an instruction being 16 0s and 1s, as is the case in the LC-3b ISA, an in- struction in assembly language consists of four parts, as shown below: LABEL. OPCODE.
