Machine Dependent Language
Assembly language is considered a machine-dependent language because it is closely tied to the architecture and instruction set of a specific computer system. Below are some key points to explain why assembly language is considered machine dependent:

Directly corresponds to machine code:
Assembly language instructions directly correspond to machine code instructions that the computer's processor can execute. Each assembly language instruction typically translates to one machine code instruction, making it closely tied to the specific hardware architecture.

Specific to processor architecture:
Different processors have different instruction sets and architectures. Assembly language code written for one type of processor may not be directly compatible with another type of processor. This means that assembly language programs are specific to the processor architecture they are written for.

Low-level programming:
Assembly language is a low-level programming language that provides a close representation of the underlying hardware. As a result, programmers need to have a deep understanding of the specific hardware architecture to write efficient assembly language programs.

Requires knowledge of hardware details:
Programmers writing in assembly language need to have detailed knowledge of the specific hardware architecture they are targeting. This includes understanding the processor's registers, memory layout, and instruction set.
In conclusion, assembly language is considered a machine-dependent language because it is closely tied to the specific hardware architecture of the computer system it is written for. It offers low-level control and efficiency but requires a deep understanding of the underlying hardware.
