Basic Architecture of a Computer A computer system is organized into several key components that work together to perform operations. These components are based on the Von Neumann architecture , which includes the CPU, memory, input/output devices, and interconnections. Here is a detailed explanation of the core components: 1. Central Processing Unit (CPU) The CPU is the brain of the computer, responsible for executing instructions. It consists of three main subcomponents: Arithmetic Logic Unit (ALU): Performs arithmetic operations (addition, subtraction, multiplication, division). Executes logical operations (AND, OR, NOT, XOR) for decision-making. Works directly with data fetched from registers or memory. Control Unit (CU): Directs and coordinates the activities of the computer. Decodes instructions fetched from memory and sends control signals to other components (ALU, memory, I/O). Ensures instructions are executed in the correct sequence. Registers: Small, high-speed storage...
The blog post titled "Lesson Plan GXEST203" by Dr. Binu V P presents a comprehensive and structured approach to the "Foundations of Computing" course, aligning with the 2024 KTU BTech curriculum. It meticulously outlines the progression from fundamental hardware concepts to advanced topics like web design, ensuring a holistic understanding for students. The integration of authoritative texts, such as Peter Norton's "Introduction to Computers" and "Invitation to Computer Science" by G. Michael Schneider and Judith Gersting, underscores the academic rigor of the plan. This lesson plan serves as a valuable resource for educators and students alike, facilitating a coherent and in-depth exploration of computing principles.
