Application development for embedded systems is usually done on a desktop computer (PC), using a high level language like C or assembly language. After the executable binary has been created by the cross development tools, this binary needs to be uploaded to the target board. In most cases it will go to some kind of non-volatile memory, requiring specific programming procedures.
While in earlier days a chip had been removed from the target board and placed in a programming device, today's microcontrollers and external memory chips can be re-programmed without being removed from the circuit. This is called in-ciruit or in-system programming.
That depends on the specific microcontroller.

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
Its a 8051 based CPU with inbuilt flash memory(ISP - In-System Programming). It can be flashed through SPI(serial peripheral Interface). AT89C51RD2 has similar features but its flash memory can be programmed through serial interface (RS-232).
The difference is base on the requirement of their0 application.
no it's not a microcontroller and lm 324 is quad low power comparator...
Microcontroller = (microprocessor+memory+peripherals) on a single chip
