Question

What are the similarities between RISC and CISC architecture ?
What are the other categories of;
1,RAM 2.ROM?
Is memory the same as storage?

Answer 1

Answer:

A microprocessor is a processing unit on a single chip. It is an integrated circuit which performs the core functions of a computer CPU. It is a multipurpose programmable silicon chip constructed using Metal Oxide Semiconductor (MOS) technology which is clock driven and register based. It accepts binary data as input and provides output after processing it as per the specification of instructions stored in the memory. These microprocessors are capable of processing 128 bits at a time at the speed of one billion instructions per second.

Characterstics of a micro processor:

Instruction Set –

Set of complete instructions that the microprocessor executes is termed as the instruction set.

Word Length –

The number of bits processed in a single instruction is called word length or word size. Greater the word size, larger the processing power of the CPU.

System Clock Speed –

Clock speed determines how fast a single instruction can be executed in a processor. The microprocessor’s pace is controlled by the System Clock. Clock speeds are generally measured in million of cycles per second (MHz) and thousand million of cycles per second (GHz). Clock speed is considered to be a very important aspect of predicting the performance of a processor.

Answer 2

RISC stands for 'Reduced Instruction Set Computer Whereas, CISC stands for Complex Instruction Set Computer. The RISC processors have a smaller set of instructions with few addressing nodes. The CISC processors have a larger set of instructions with many addressing nodes.

There are different types of RAM , including DRAM ( Dynamic Random Access Memory) and SRAM (Static Random Access Memory).

There are many different types of ROM, including PROM ( Programmable read - only Memory) that is manufacturered as black memory (e.g. a CD - ROM) and EPROM ( Erasable Programmable read only Memory).

Memory is basically made of RAM chips, while storage, in general terms, refers to hard drives or solid-state drives. Both terms are technically the same and it can be confusing at times because they are measured in same units: bytes, kilobytes, megabytes, etc.
