How do you calculate effective address?
To calculate the effective address in a computer system, you typically follow a formula that incorporates the base address, index, and offset. The effective address is determined by adding the base address to the product of the index register and the scale factor, along with any immediate offset. The general formula can be expressed as: Effective Address = Base Address + (Index × Scale) + Offset. This calculation is commonly used in assembly language and memory addressing modes.
What does physical address mean?
The physical address is the final address that is presented to the bus, at the pins of the microprocessor chip, to form the address of the desired item in memory.In the 8085, physical and effective addresses are one and the same.In the 8086/8088, the physical address is the effective address plus 16 times one of the segment registers.In higher level processors, such as the 80386 and beyond, the physical address is formed by lookup of the effective address in a page table to convert from virtual/effective address to physical, or linear, address.The effective/virtual address is the address generated by the instruction and the programmer, without regard to any underlying addressing scheme. This is the address used when considering the "programming model", in "user mode".
Difference between effective address and physical address?
The effective address is the address generated by the program, after all transformations, such as index registers, offsets, addressing mode, etc. have been made. The physical address is the address generated by the hardware, after performing whatever lookups through the page table, etc. have been made. The effective address, or virtual address, is the concern of the program. The physical address, or real address, is the concern of the operating system.
What is meant by effective address in microprocessor?
Effective address is the final address generated by offsetting and indexing which is sent to the virtual translation logic. It is the address of the operand in the virtual address space of the process, but not necessarily the address of the operand in the physical address space of the computer. In the 8085, efffective/virtual address is the same as physical address, because there is no virtual addressing logic in the 8085. In the 8086/8088, effective/virtual address is the same as physical address, but only in real mode. For example, in the 8086/8088, if the EBX register contains 1000000H, then the instruction MOV EAX,[EBX+1234H] has an effective address of 10001234H.

What is effective address or offset?
the address that is obtained by applying any specified indexing or indirect addressing rules to specified address
What is physical address in 8086 microprocessor?
Physical address in the 8086/8088 is {Selected Segment Register} * 16 + {Effective Offset Address}. It is a 20-bit address .
What is the name of register which contains the effective address of the operand?
The register that contains the effective address of the operand is typically called the "Address Register" or "Effective Address Register." In many architectures, this role is fulfilled by the Program Counter (PC) or specific registers like the Base Register or Index Register, depending on the addressing mode being used. These registers are essential for accessing memory locations during program execution.

Explain the concept of segement memory if the 8086 excution unit calculates an effective address of 14A3H and DS contains 7000H what physical address will the BIU produce?
Segmented memory in the 8086/8088 means that the effective address is added to 16 times the segment address. In the question, an effective address of 14A3H with DS of 7000H, means the physical address is 714A3H. However, the BIU in the 8086 only addresses words, not bytes, so the address generated is 714A2H. If the operation required more than one byte of data, subsequent even addresses of 714A4H, 714A6H, etc. would be generated.
