Definition of Indirect addressing

•  the address to be used is formed by:operand + the contents of the Index register.

• the operand is the address where the data is stored.

• the operand is an address,that address where the data is stored.

• the numeric address of a memory location.

In Relative Addressing,The data to be used is stored

• In the address which can be found by adding the operand to the

  value in the IX register

• In the address x locations away from the current address (where x

  is the value in the operand)

• In the address that is stored in the address in the operand

• In that address

what is Immediate addressing

• the operand is an address,that address where the data is stored.

•  the numeric address of a memory location.

• representation of actual memory using symbolic names or labels.

• the operand is not an address, the operand is the actual value to be loaded.

In Indirect Addressing, The data to be used is stored

• In the address that is stored in the address in the operand

• In the operand

• In the address which can be found by adding the operand to the

  value in the IX register

• In the address that is stored in the address in the operand

A ………… is a sequence of instructions that are given a identifier.These instructions may need to be executed several times.

In Indexed Addressing,The data to be used is stored

• In the operand

• In the address x locations away from the current address (where x

  is the value in the operand)

• In the address which can be found by adding the operand to the

  value in the IX register

• In that address

What is Absolute addressing 

•  the operand is the offset from the current address where the value to be used is stored.

• the numeric address of a memory location.

• the operand is an address,that address where the data is stored.

• the operand is not an address, the operand is the actual value to be loaded.

Which description about Second Pass is correct

• Remove comments

• 1.Replace symbolic addresses with the absolute address

  2.Replace opcode mnemonic names with binary equivalent

• Create a symbolic address table

• Convert constants into binary

A ………… is an instructions that tells the assembler to do something. it is not a program instruction
