it is a programmable logic device which has a inbuilt memory, clock etc and is required to perform a specific task.
That depends on the specific microcontroller.
A flash microcontroller is a type of microcontroller that uses flash memory for data storage and program execution. Flash memory allows for reprogrammability, enabling developers to update firmware or modify applications easily. This characteristic makes flash microcontrollers versatile and widely used in embedded systems, consumer electronics, and various automation applications. Their ability to retain data without power and support rapid read/write cycles enhances their functionality in diverse projects.
Microcontroller = (microprocessor+memory+peripherals) on a single chip
The PIC is a specific architecture of microcontroller.
Microcontroller have inbuilt memory, interrupts, etc. Which you will need to connect externally in microprocessor. Thus, Microcontroller is better than microprocessors
making EA pin high(i.e connecting it to +5V) means that microcontroller should look for the code in its internal memory. while making it low(i.e connecting it to GND) means that microcontroller should look for the code in the memory which is externally connected by the user. so when there is no external memory connected, simply tie EA pin to +5V supply.

The PIC16F877A microcontroller has 13 address lines, which allows it to address 8K words of program memory. This enables it to access a range of memory locations for storing instructions. Additionally, it has 368 bytes of data RAM and 256 bytes of Electrically Erasable Programmable Read-Only Memory (EEPROM) for data storage.

On-chip memory is a memory that resides on microcontroller itself. e.g RAM. It may be one of the Internal RAM or Special Function Register (SFR). Off-chip memory is external ROM or EPROM.
Data transfer instructions in the 8051 microcontroller are used to move data between registers, memory, and I/O ports. Key instructions include MOV (to transfer data between registers or memory), MOVC (to move data from code memory), and MOVX (to access external data memory). These instructions facilitate the manipulation and transportation of data within the microcontroller's architecture, enabling various operations in embedded applications.
