Explain the differences between Assembly Language and High Level Language?

Answer 1

Assembly language is used to write programs using the instruction set for a particular processor/controller.(example : 8051 or 8086 or MIPS).

• It is confined to a particular machine, it involves symbolic representation of the binary machine codes and other constants needed to program a given CPU architecture.

Assembly Language require an ASSEMBLER to convert the assembly code to machine level code(HEX CODE)

High Level Language require a Compiler to convert into ASSEMBLY THEN machine level code.(Now-a-days compilers are smart enough to generate the machine code directly)

To write assembly code it is necessary to know the architecture of the processor or controller.

To write an High Level Program it is not neccessay to know the architecture completly.

Assembly language is not protable.

High Level Language is Portable.

Answer--Assembly language :-

A programming language that is once removed from a computer's machine language. Machine languages consist entirely of numbers and are almost impossible for humans to read and write. Assembly languages have the same structure and set of commands as machine languages, but they enable a programmer to use names instead of numbers.

Each type of CPU has its own machine language and assembly language, so an assembly language program written for one type of CPU won't run on another. In the early days of programming, all programs were written in assembly language. Now, most programs are written in a high-level language such as FORTRAN or C. Programmers still use assembly language when speed is essential or when they need to perform an operation that isn't possible in a high-level language.

High-level language:-

• A high level language hides the micro abstractions such as set of command required to be performed by the processors such as CPU. Java and C++ are all high level languages.
• Java, C++ : all easy to write non-binary languages
• Example : (i=10, i<10,i++)
• It is not confined to particular machine.

-JP Morgan

A programming language such as C, FORTRAN, or Pascal that enables a programmer to write programs that are more or less independent of a particular type of computer. Such languages are considered high-level because they are closer to human languages and further from machine languages. In contrast, assembly languages are considered low-level because they are very close to machine languages.

The main advantage of high-level languages over low-level languages is that they are easier to read, write, and maintain. Ultimately, programs written in a high-level language must be translated into machine language by a compiler or interpreter.

The first high-level programming languages were designed in the 1950s. Now there are dozens of different languages, including Ada, Algol, BASIC, COBOL, C, C++, FORTRAN, LISP, Pascal, and Prolog.

An assembly language is where each statement corresponds to one machine instruction. A high level language is where each statement corresponds to more than one, sometimes many, machine instructions.

Answer 2

firstly let start with machine level language. it is the language in the form of binary bits known as "0" and "1"

this help the machine to understand the OFF and the ON case respectively.

usind 0 and 1 (i.e. machine understanding letters) we can communicate with the hardware.

now

Assembly language are those which is low level language but is very powerfull as because the different compilers which are built for C/C++/Java/Oracle/..etc. are built from it. apprantly the function of particular compiler can be written with the compiler itself.

but the main algorithms are written in assembly level language and is compiled in the form of machine level language and stored within the header file.

It is the Assembler that translate the high level language into the machine code.

now

high level language are written in English language for our better understanding but the logic behind it is that when an algorithms is written in C/C++/Java/Oracle/...etc they are compiled and stored in the form of Assembly language by the help of the compiler names "Assembler". and then it is the assembler which translate this codes into the machine level language from where it is given to the Control memory , and it gets transfered to the CPU for execution.

Ultimately we got... High Level Language are used for our convience to write algorithms , Assembler which compiles the Assembly language compile it in the machine level language, which helps to communicate with the hardware.

Hope you got what you want...

Answer 3

Assembly language :-

The computation in assembly language program is less than machine language.

This program runs faster to produce the desired result as compared to high lavel language.

This programme contains more instruction than High level language.

The programme written on one computer can't be used on any other computer.

High level language :-

The computation in high lavel language program is less than assembly language.

this program runs slower to produce the desired result as compared to Assembly language.

This programme Contains less instruction than Assembly Language.

The programme written on one computer can be used on other computer.

Answer 4

In one word: abstraction.

A simple example: the well known Hello World console print out.

In Java:

class HelloWorld{

public static void main(String[] args){

system.out.println("Hello World");

}

}

In Assembler:

.data

out: .asciiz "Hallo Welt"

.text

main: li $v0, 4

la $a0, out

syscall

li $v0, 10

syscall

High level programming languages are more intuitive to use.

Also regarding to secutity high level languages are safer.

Answer 5

it is the language between High language (ex: C , C# , C++ , Java)

and machine language

Machine Language ....> Assembly Language .....> High-Level Language

(0 1) ( ADDF3 R1, R2, R3) (prinf("ethar");)

Answer 6

Forget it. Choose a high-level language (C, Java, PHP, whatever), and use that. There is no need to develop new programming languages; actually, there are more than enough of them.

Answer 7

The second generation (2GL)

Answer 8

Well, you don't have to.
