Organization & Structure of a Computer System.

7. Computer System Architecture

Computer System Architecture

Architecture describes the logical structure and operational principles of a computer. The most common architectures are:

Computer System Architecture

Computer systems are categorized into different architectures based on how they process data and execute instructions.

This describes a design architecture for an electronic digital computer with parts consisting of Computer Technology

 

Types of Computer Architecture

1. Von Neumann Architecture

This is the most widely used computer architecture, based on the model proposed by John von Neumann in 1945. John von Neumann, along with others, proposed the concept of the stored program that we use even today. The idea was to keep a program in the memory and read the instructions from it. He also proposed an architecture that clearly identified the components we have presented previously: ALU, control, input, output, and memory as illustrated in Figure 1. This architecture is known as the von Neumann architecture.

This architecture uses what is known as the stored program model. In the von Neumann architecture, the stored program is the most important aspect of the von Neumann model.
