Understanding the Differences in Computer Architecture

All computers are not created equal. The differences in architecture have a substantial impact on performance and system security. However, every computer has three basic types of components:

Central Processing Unit The first component group centers around the central processing unit, also known as the CPU. The CPU performs mathematical calculations with the assistance of an internal arithmetic logic unit, a high-speed memory cache, and working memory space known as random access memory (RAM).
