Question

Explain processor and memory architectur of computer system

Answer 1

The main components in a typicalcomputer system are the processor,memory, input/output devices, and the communication channels that connect them. The processor is the workhorse of the system; it is the component that executes a program by performing arithmetic and logical operations on data.

There are three categories of computer architecture:

System Design: This includes all hardware components in the system, including data processors aside from the CPU, such as the graphics processing unit and direct memory access. It also includes memory controllers, data paths and miscellaneous things like multiprocessing and virtualization.

Instruction Set Architecture (ISA): This is the embedded programming language of the central processing unit. It defines the CPU's functions and capabilities based on what programming it can perform or process. This includes the word size, processor register types, memory addressing modes, data formats and the instruction set that programmers use.

Microarchitecture: Otherwise known as computer organization, this type of architecture defines the data paths, data processing and storage elements, as well as how they should be implemented in the ISA.
