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.

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 the difference between Gross Domestic Product and Gross National Product?
The Gross Domestic Product and Gross National Product are measurements of the value of the total worth of a nation. Domestic product calculates based on the physical borders of the country, whereas the National product calculates based on its citizens, even if those citizens are out of the country.
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".
