I dont know why I always get stuck in the microprocessors things. I'm having a course of 8086 microprocessor. I ahve following questions. Please answer them in detail-
1. The address bus is of 20 bits, so this means that 8086 can access 1M of memory. I dont understand what this means. Does this mean that we can attach 1M of RAM to it? Please explain in detail as if you are explaining a real stupid. Really I'm a real noooooooooob when it comes to deal with memory and registers.
2. Why does the 8086 need 4 segment registers of 64K? I've also read 8085 but there was no need of such segment registers.
I have gone through my book and few websites but none of them explains the memory part in detail.
