    Hi.. I have learned the assembly language at University..and I understood that it is the second level language(after machine language(1,0)) but i dont know in which field is it important today and how? I mean using C# and C++ for example is easier and can perform all OS functions so for what could we need assembly language?! "I am too late but i will never give up"

      Aseembly langauge is of very limited use now. It's used to write an initial bootstrap compiler for a new cpu architecture. Some embeded systems are still largely programmed in asm because the market's too small to justify making a quality compiler for them. Beyond that it's still useful for the inner loops of a highly processor intensive/time critical application. The cavaet is that you need to be really good to outperform a modern compiler these days.

        Dear dan neely, Assembly language used widely it is using very more in secuirty field and protocols programming

          Largely used in embedded systems. Sometimes pure C could be a good choice for to save development's time, however it could not replace ASM completely. Have you ever heard of "SMALL IS BEAUTIFUL" phrase, its very nice to describe ASM. Jup

            I've seen it used in game/graphics code, where millions of iterations through a loop can really benefit from some hand coded assembly, mainly to keep the frame rate up. Haven't touched it myself, since the good old DOS days....

              Dear Anh_Tuan, Yes , What you said is right, But sometimes you can not do things in c or c++ , you must do these in Assembly Languages. :-O ala qunaibi :-O ala qunaibi
