COMPUTER FUNDAMENTALS

Detailed explanation-1: -Which of the following is not a microprocessor? Explanation: Z8000, Motorola 6809, and Zilog Z8 are microprocessors but PIC1x is an 8-bit microcontroller.

Detailed explanation-2: -The DRAM which form the main memory are slow devices. This reduces the speed of execution . To speed up the process, high speed memories such as SRAMs must be used. In the memory system, small section of SRAM is added along with main memory referred to as cache memory.

Detailed explanation-3: -Microprocessor consist of ALU, Cache memory and Control Unit. Register-Microprocessor has not array as it’s part but it has Register array that contains set of registers whereas register are not part of microprocessor, it is a part of register array.

Detailed explanation-4: -What is true about microprocessor? C. It also communicate with the other devices connected to it. Explanation: Microprocessor is a controlling unit of a micro-computer, fabricated on a small chip capable of performing ALU (Arithmetic Logical Unit) operations and communicating with the other devices connected to it.
