To find memory addressing

Memory Addressing:-

Today i will teach you how to find memory address where it starts and then ends.

let we take a memory of 1K, in hexadecimal 1k memory is about 400H, for 8086 microprocessor it will generate 20 bit address, so we know that final address of microprocessor is FFFFF H   means microprocessor will generate its last adress of 
1111 1111 1111 1111 1111  , F means 1111 now to find its starting address 
             (FFFFF - 400)  then add 1 = FFC00
this is the starting address
