Base Register Addressing Mode | Computer Architecture

In this lecture, we explain the Base Register Addressing Mode in Computer Architecture and Organization (CAO) with a clear and step-by-step approach. This addressing mode calculates the effective address by adding the base register value to an offset (displacement). Understanding this concept is essential for learning how processors access memory efficiently and support relocation, arrays, and structured data access. 📘 Topics Covered: What is Base Register Addressing Mode Formula: Effective Address (EA = Base Register + Offset) Role of Base Register Step-by-step numerical example Advantages of base addressing Real-world use cases in programs 🎓 Best For: BSCS / BSIT / Software Engineering students Computer Architecture learners PPSC / FPSC / university exam preparation 🗣️ Language: Urdu / Hindi 📌 Master how base register addressing improves memory access and flexibility.
