difference between register and memory location
A register is a temporary storage area for a byte or word on a CPU.
A memory location is within RAM.
Simple answer - speed. By using the CPU register, the information is kept "local" to the CPU. By storing a value in a memory location, a lookup has to be performed to retrieve it.
Registers are normally memory spaces internal to the processor or very close to it. They are generally faster than main memory and will be small in size and will hold very frequently used data.Register stacks are a set of such register memory locations.Memory refers to computers main memory outside CPU. It is used to keep data and programs. Memory stack is a series of memory locations.The difference between register stack and memory stack is...

LOAD-means to keep an instruction or prog on the memory i.e ram STORE-means to keep the result or instruction or prog to a permanent location for further use load means take a prog to memory. store means save the prog to the parmanent memory
MAR is memory address register. MDR is memory data register. These are registers part of the control unit (CU) in your cpu.
A memory mapped register is a register that has its specific address stored in a known memory location.
In other words, MAR holds the memory location of data that needs to be accessed. When reading from memory, data addressed by MAR is fed into the MDR (memory data register) and then used by the CPU. When writing to memory, the CPU writes data from MDR to the memory location whose address is stored in MAR. The Memory Address Register is half of a minimal interface between a microprogram and computer storage. The other half is a memory data register. Far more complex memory interfaces exist, but this is the least that can work.

INR increment the content of register/memory by 1and result is stored in same place. INX increment the register pair by 1(no flags are affected)

The program counter in the processor holds the address of the next instruction needed from main memory. The program counter copies its contents into the memory address register. The memory address register then sends the address along the address bus to main memory and the contents of the memory location specified by the address are sent along the data bus to the memory buffer register. The contents of the memory buffer register are then copied to the current instruction register where they are decoded and executed.

The biggest difference between these two loaders is that absolute loaders will load files into a specific location and a relocating loader will place the data anywhere in the memory.
