The 89S52 has four different ports. Each one of the ports has eight input/output lines. The ports are used to output data.
That depends on the specific microcontroller.
The PIC is a specific architecture of microcontroller.
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.

A feedback control system can be made involving microcontroller 8051, inverter(gating circuit), power processing unit, induction motor whose speed is measured via digital tachometer. The microcontroller will act as a Frequency Counter, Comparator and PID Controller. The output from tachometer(digital) will be given to microcontroller which will compare this to the reference signal and then pass the control signal to gating circuit.The power unit's output will be given to motor.
You actually have that reversed. A microcontroller is connected to a relay via a ULN2803 (or other power device driver IC) because the output pins of the microcontroller can't drive relays. The ULN2803 darlington transistors provide the power amplification and the inductive kickback protection needed to drive the relay while only lightly loading the microprocessor output pins.
A programmable electronic device that can input process output and store data means a microcontroller which has an inbuilt ram,rom and i/o's . A programmable electronic device that can input process output and store data means a microcontroller which has an inbuilt ram,rom and i/o's . -------------- although that sounds nice, the text book answer is "computer"
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.
