Assembly language program segment

How do I switch the assembler to a text segment?

When the assembler is given a source file to translate
It starts out assembling to the text segment. You can switch which segment is being assembled to by using the following directives:
Switch to text segment. Switch to initialized part of data segment. Switch to uninitialized part of data segment.

How does the assembler keep track of where it is assembling?

During the time the assembler is reading through and translating an assembly-language program
It always keeps track of where it is currently assembling to:
The text segment
The initialized part of the data segment
Or the so-called uninitialized (really zero-initialized) part of the data segment.

What happens when an assembly-language program is assembled?

When an assembly-language program is assembled
The translation that the assembler carries out is essentially the construction of the text segment and the data segment. (The stack grows and shrinks along with function calls and returns during execution
So it doesn't need to be built by the assembler.)

What is a segmented memory model?

A segmented memory model divides the system memory into groups of independent segments referenced by pointers located in the segment registers. Each segment is used to contain a specific type of data. One segment is used to contain instruction codes
Another segment stores the data elements
And a third segment keeps the program stack.

What is a code segment?

Code segment − It is represented by .text section. This defines an area in memory that stores the instruction codes. This is also a fixed area. Stack − This segment contains data values passed to functions and procedures within the program. Assembly Memory Segments - We have already discussed the three sections of an assembly program.
