FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -A microcomputer is a small, relatively inexpensive computer having a central processing unit (CPU) made out of a microprocessor.

Detailed explanation-2: -Smaller than a mainframe or minicomputer, a microcomputer uses a single integrated semiconductor chip for its central processing unit (CPU).

Detailed explanation-3: -Number of bits that can be processed by a processor in a single instruction is called its word size. Word size determines the amount of RAM that can be accessed at one go and total number of pins on the microprocessor. Total number of input and output pins in turn determines the architecture of the microprocessor.

Detailed explanation-4: -Historically, microprocessors and microcontrollers have come in “standard sizes” of 8 bits, 16 bits, 32 bits, and 64 bits. These sizes are common, but that does not mean that other sizes are not available.
