In the 8085, the high order address is A8-A15. In the 8086/8088, the high order address is A8-A19. (For a 16-bit address, the answer is A8-A15, but the answer above reflects the chosen categories, 8085 and 8086/8088, with the 8086/8088 running in 20-bit mode.) In Windows XP, running in 32-bit mode, the high order address is A8-A31, a 32 bit address.

How multiplixed data and address bus of 8086 can be de-multiplixed?
The 8086 has a 20 bit address bus and a 16 bit data bus. The low order 16 bits of the address bus share the same 16 pins as the data bus. The low order 16 bits of the address are emitted in the first clock cycle of a memory access cycle. External logic is expected to latch that address. Then the bus becomes a data bus. The high order 4 bits of the address bus are handled separately.The determination of operand size (8 bit vs 16 bit) is made by BHE and A0. If BHE is high, it is a 16 bit operand at an even address. If BHE is low and A0 is low, it is an 8 bit operand at an even address. If BHE is low and A0 is high, it is an 8 bit operand at an odd address.
Why program counter and stack pointer is 16- bit?
Because that's how Intel designed it. Even though the 8085 is an 8-bit computer, the program counter and stack pointer are 16 bits wide in order to support the address bus, which is also 16 bits wide. In the case of the 8086/8088, the program counter and stack pointer are still 16 bits wide, even though the address bus is 20 bits wide, because the 8086/8088 adds segmentation through the 16 bit segment register which is left shifted by 4.
What is a Mac address and what is the bit size of a Mac address in a nic?
MAC bit size is 16 digits. but MAC bit is 48 each.
Why segment is 64k in microprocessor?
Because the processor is a 16 bit processor, and 64k is what you can address with a 16 bit processor.
How many address bits does 8085 have?
The 8085 has a 16 bit address bus.
What is 16 bit addresses?
Bit means binary digit. A bit can be either a zero or a one.A 16-bit address refers to the length of the address. With a length of 16 bits, you can address a total of about 65,000 positions (that's 2 to the power 16). For many years now, computers have used 32-bit addresses; since this basically limits them to accessing 4 GB of RAM, more recently, they have started to use 64-bit addresses.
How are segment registers used to form a 20-bit address?
The 16 bit segment register is left shifted by 4 and added to the effective address to form a 20 bit physical address.
What acronym is used for a 16-bit path?
ip address
How many memory locations can be addressed by a μp with 16-address line?
A 16 bit address bus can select 65536 locations.
How many Address line of 8085 microprocessor?
There are 20 address lines and 16 data lines in the 8086 microprocessor. The low order 16 address lines are multiplexed with the data lines. Some of the high order address lines are multiplexed with status lines.
Size of 8086 address bus?
The 8086/8088 has an internal 20-bit address bus and 16-bit data bus. Externally, the address bus is 20-bits, and the data bus is 16-bits for the 8086 and 8-bits for the 8088.The data bus in the 8086 is 16 bits in size, while the address bus is 20.
Which processor had a 32-bit internal bus and a 16-bit external bus?
Which processor has a 32-bit Data Bus and a 24-bit Address Bus?
