stack segment register
What is the purpose of literals in assembly language?
literals are used to store constant values which are not changed even after program execution
Which program translates an assembly language program into a high-level language?
A High level language is a language like C, Pascal, Fortran. To convert, the easiest way is to use a compiler. A compiler will take the instructions written in a high level language and convert them into machine code which is the specific instruction set for that type of computer. Assembly language is just a human readable form of a machine code which is how the designers of the computer instruction set made it work. A disassembler will show the assembly language from machine code. But the compiler usually includes a lot of optimisations from a the high level language and will not often generate very simple assembly.
What is Volatile in c language?
'int' is the type, 'volatile' warns the compiler, that the value might be changed asynchronousy, so it mustn't be optimized (e.g. cached in register.)
How has the assembly line changed over the years?
it changed by... well it changed... It just changed!
Why is Unix more portable than other operating systems?
Unix was rewritten in the C programming language and not in assembly language. The migration from assembly language to the higher-level language C resulted in much more portable software, requiring only a relatively small amount of machine-dependent code to be replaced when porting Unix to other computing platforms. Unix manages the hardware and the executing processes by the kernel. The kernel is a collection of programs written in C which directly communicate with the hardware. applications communicate to system using kernal. Hence kernal need to be changed for different hardware but user interface remains same.

How did the Michif language change over the time?
The michif language changed over time with how the earth changed. The language changed so that people can learn it better with how the word is said and spelled.
A Explain the use of Code Segment CS and data segment DS register in 8086 microprocessor?
Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions. The processor uses CS segment for all accesses to instructions referenced by instruction pointer (IP) register. CS register cannot be changed directly. The CS register is automatically updated during far jump, far call and far return instructions. Data segment (DS) is a 16-bit register containing address of 64KB segment with program data. By default, the processor assumes that all data referenced by general registers (AX, BX, CX, DX) and index register (SI, DI) is located in the data segment. DS register can be changed directly using POP and LDS instructions. Code segment (CS) is a 16-bit register containing address of 64 KB segment with processor instructions.
