addressing modes 8086

What is an addressing mode?

• A method of locating a memory location
• A way to load registers
• A method to perform arithmetic operations
• A way to execute a program

Which addressing mode uses a fixed memory address?

• Absolute addressing mode
• Immediate addressing mode
• Indexed addressing mode
• Indirect addressing mode

What is the difference between direct and indirect addressing modes?

• Direct addressing mode refers to memory location, while indirect addressing mode refers to a register that points to memory location.
• Direct addressing mode refers to a register that points to memory location, while indirect addressing mode refers to memory location
• Direct addressing mode is used for arithmetic operations, while indirect addressing mode is used for branching
• Direct addressing mode is used for branching, while indirect addressing mode is used for arithmetic operations

Which addressing mode involves the use of a base register and an offset value?

• Based Indexed addressing mode
• Immediate addressing mode
• Indirect addressing mode
• Direct addressing mode

What is the advantage of the indexed addressing mode?

• It allows you to access data stored in a table or array.
• It enables you to perform arithmetic operations on data stored in memory.
• It is the fastest addressing mode
• It is the easiest addressing mode to program.

Which addressing mode is used when the data to be accessed is located in the same memory location as the instruction?

• Immediate addressing mode
• Absolute addressing mode
• Indirect addressing mode
• Direct addressing mode

What is the difference between immediate and direct addressing modes?

• Immediate addressing mode uses a constant value, while direct addressing mode uses a memory location.
• Immediate addressing mode uses a memory location, while direct addressing mode uses a constant value.
• Immediate addressing mode is used for branching, while direct addressing mode is used for arithmetic operations.
• Immediate addressing mode is used for arithmetic operations, while direct addressing mode is used for branching.

Which addressing mode is used when the location of data is not known until the program is executed?

• Indirect addressing mode
• Direct addressing mode
• Based Indexed addressing mode
• Immediate addressing mode

Which addressing mode is used when you want to access data that is stored in the same register as the instruction?

• Register addressing mode
• Indexed addressing mode
• Direct addressing mode
• Indirect addressing mode

Which addressing mode is used to transfer data between different segments in memory?

• Pointer addressing mode
• Direct addressing mode
• Indirect addressing mode
• Based Indexed addressing mode
