Because Intel designed it that way. The 8085 was designed as a 8 bit computer in a 16 bit address space. This means that the PC (Program Counter) and SP (Stack Pointer) should be 16 bits in size.
The program counter (PC) and stack pointer (SP) registers are 16-bit registers in the 8085 and in the 8086/8088 because that is how Intel designed the processors.
The various 16-bit registers on the 8085 are BC, DE, HL, SP, PC.
Yes.
The 8085 is an 8-bit microprocessor. Even though there are some 16-bit registers (BC, DE, HL, SP, PC), with some 16-bit operations that can be performed on them, and a 16-bit address bus, the accumulator (A), the arithmetic logic unit (ALU), and the data bus are 8-bits in size, making the 8085 an 8-bit computer.
The stack size of Intel's 8085 microprocessor is theoretically 64 kb, but the real limit is a function of memory and program architecture and layout. The stack pointer is 16 bits, but that is not the same as stack size.
Depends on the caliber and barrel length the SP 101
1. Memory Read - (PC) and then increment PC - Op Code C1 - Four clocks 2. Memory Read - (SP) and then increment SP - Transfer to C - Three clocks 3. Memory Read - (SP) and then increment SP - Transfer to B - Three clocks
Program Counter( PC)stores the 16-bit memory address of the next instruction to be fetched. Stack Pointer (SP)stores the address of a memory location which is used as a stack.

All 16 of the x64 architecture's G.P. registers can be addressed as 16-bit registers, using the names AX, BX, CX, DX, SI, DI, BP, SP, R8w, R9w, R10w, R11w, R12w, R13w, R14w, and R15w. Using SP as a G.P. register is not a good idea, however, since this will conflict with its function as the stack pointer.
