Yes. Today's microprocessors have many, many times more transistors than those of the 1970's.
Yes, today's computers use transistors and microprocessors. Smaller transistors subset the amount of RAM that is local to the CPU at any given moment.
The program used inside microprocessors is microcode,the program what microprocessors execute is machine code.
As of the end of 2016, high end multicore microprocessors have from 3,000,000,000 to 8,000,000,000 transistors. But there are plenty of other medium range microprocessors and microcontrollers with much fewer transistors being manufactured.

Microprocessors.
Microprocessors have made communication even more efficient. This is because they are embedded in most modern communication equipment, extending their capabilities.
Microprocessors. Nearly all of today's laptops and computers have a microprocessor being used as their CPU (central processing unit)

A regulated power supply
A 7 segment display is an I/O device, and it is not necessarily used in microprocessors. The choice of I/O devices is a function of system design, not microprocessor design.
