Detailed explanation-1: -Answer: It is 2^14 memory lacations can be addressed by a microprocessor with 14 address lines.
Detailed explanation-2: -In 8085 microprocessor, Address bus is of 16 bits (A0-A15) and can transfer maximum 16 bit address and hence can address 65, 536 different memory locations.
Detailed explanation-3: -Data bus is used to transfer data from one unit to another unit of the computer system. Microprocessor can read data from the memory or write data to the memory. So, the data bus is bidirectional.
Detailed explanation-4: -Explanation: For n memory locations, log n(to the base of 2) address lines are required. For addressing 4K bytes of memory, 12 address lines are required since log(4KB) =log(4*1024)=log(212)=12. Explanation: Since for n address lines, the number of memory locations able to address is 2^n.
