What is assembly language short answer?

An assembly language is a type of low-level programming language that is intended to communicate directly with a computer’s hardware. Unlike machine language, which consists of binary and hexadecimal characters, assembly languages are designed to be readable by humans.

What is mnemonics in assembly language?

Generally, a mnemonic is a symbolic name for a single executable machine language instruction (an opcode), and there is at least one opcode mnemonic defined for each machine language instruction. Each instruction typically consists of an operation or opcode plus zero or more operands.

Which code is used in assembly language?

Machine code is very hard to follow because it uses binary code to represent the instructions. To provide a more human friendly version of machine code, assembly language is used. An assembly language statement is a line of text that translates into a single machine instruction.

What is machine language in short?

Machine language, or machine code, is a low-level language comprised of binary digits (ones and zeros). Since computers are digital devices, they only recognize binary data. Every program, video, image, and character of text is represented in binary. This binary data, or machine code, is processed as input by the CPU.

Why is it called assembly language?

The Name Derives from the Program/Process Created to Read it “In the very early days of computing, programmers wrote code in binary machine instructions and entered it into the computer through a bank of toggle switches. This was tedious, to say the least.

Is machine a code?

Machine code is a computer program written in machine language. It uses the instruction set of a particular computer architecture. Machine code is the lowest level of software. Other programming languages are translated into machine code so the computer can execute them.

What are mnemonics and opcodes?

As nouns the difference between mnemonic and opcode is that mnemonic is anything (especially something in verbal form) used to help remember something while opcode is (computing) a mnemonic used to refer to a microprocessor instruction in assembly language.

What is Lea Assembly?

The lea instruction places the address specified by its first operand into the register specified by its second operand. Note, the contents of the memory location are not loaded, only the effective address is computed and placed into the register.

Can humans read machine code?

Short answer: yes. I can read and understand executable binary instructions for dozens of machines (as well as binary code in ASCII, Ebcdic, display-code, etc. and even rad 50 .) However, you usually need a cheat sheet listing the opcodes, field definitions, etc.

Why binary language is called machine language?

a computer(the machine) operates on electricity. thus,it can understand only electricity signals that are just two ON and OFF or high voltage or low voltage. the binary language is often termed as machine language as it fulfills the condition of using 2 unique symbols to represent state of electricity.

What is assembly language programming?

Assembly Language Programming is a low level programming language which is processor specific. It means it will run only on the processor architecture for which it was written. Pros: Faster- Basically assembly language program are executed in much less time as compared to the high-level programing language like c,c+.

What are examples of mnemonics in assembly language?

Examples of mnemonics in assembly language include add, which adds data, and mov, which moves data from one place to another. Because ‘mnemonic’ is an uncommon word, the phrase instruction type or just instruction is sometimes used instead, often incorrectly. The words and numbers after the first word give more information about what to do.

How difficult is it to read assembly language?

It is very difficult for a person to read and understand it even if that person knows machine code. With assembly language, each instruction can be written as a short word, called a mnemonic, followed by other things like numbers or other short words.

What is the difference between disassemblers and assemblers?

Disassemblers, which turn machine code into assembly language, do the opposite of assemblers, which turn assembly language into machine code. An understanding of how computers are organized, how they seem to work at a very low level, is needed to understand how an assembly language program works.
