Registers are small memory elements of size in few byte or word. Registers can be accessed quickly by the ALU (Arithmetic and Logic Unit) of micro controllers.
That depends on the specific microcontroller.
The address range of the Special Function Register (SFR) bank in the 8051 microcontroller architecture typically spans from 0x80 to 0xFF. This range includes various control and status registers used for configuring and managing the microcontroller's operation. Each SFR has a specific function, such as timer control, interrupt management, and I/O port settings. Accessing these registers allows for low-level hardware manipulation and control.

The PIC is a specific architecture of microcontroller.
The voltage of the 8031 microcontroller is 2.7V to 5.5V.
The 8051 Microcontroller is a microcontroller ("chip") developed by Intel in 1980.
PIC Microcontroller which means Peripheral Interface Controller. PIC Microcontroller is originally developed by General Instrument's Microelectronics Division.
Segger Microcontroller Systems was created in 1991.
to determine the state condition of microcontroller's input when microcontroller is reading the input port
The difference is base on the requirement of their0 application.
Microcontroller = (microprocessor+memory+peripherals) on a single chip
no it's not a microcontroller and lm 324 is quad low power comparator...
