What are machine dependent and machine-independent features?

Machine-dependent software is software that runs only on a specific computer. Applications that run on multiple computer architectures are called machine-independent, or cross-platform.

Which of the features of assembler are machine dependent Mcq?

Instruction formats. Addressing modes. Program relocation.

What are the features of assembly language?

The features of the assembly language are mentioned below:

• It can use mnemonic than numeric operation code, and it also provides the information of any error in the code.
• This language helps in specifying the symbolic operand that means it does not need to specify the machine address of that operand.

What are the features of machine independent assembler?

Machine Independent Assembler Features Literal, Symbol, Expression Literals • Motivation –It is convenient if a programmer can write the value of a constant operand as a part of the instruction that uses it. –This avoids having to define the constant elsewhere in the program and make up a label for it.

What is a bootstrap loader in machine independent assembler?

Bootstrap loader loads the first program to be run by the computer. Hardware relocation eliminates the need for the loader to perform program relocation. A direct linking loader is a loader that links two or more programs together. Did you find this document useful? Is this content inappropriate?

Which is the best definition of machine dependent software?

Machine-dependent software is application programming that runs only on a specific kind of PC. On the other hand, applications that keep running on an assortment of distinctive sorts of PCs are called machine-independent, or cross-platform.

How does pass-2 of assembler generate machine code?

Working of Pass-2: Pass-2 of assembler generates machine code by converting symbolic machine-opcodes into their respective bit configuration (machine understandable form). It stores all machine-opcodes in MOT table (op-code table) with symbolic code, their length and their bit configuration.
