COA | Unit-4 | Lecture-42 | Random Access Memory (RAM) | AKTU B.Tech Computer Science

Описание: Welcome to CS Pathshala! 🎓

In this video, we explain the concept of RAM (Random Access Memory) — the primary volatile memory used by the CPU to store data and instructions currently under execution.

You’ll learn what RAM is, how it works, and why it plays a crucial role in determining the speed and performance of a computer system.
We cover all important concepts including:

🔹 What is RAM? (Definition & Basic Concept)
🔹 Why RAM is Called Random Access Memory
🔹 Working of RAM
🔹 Types of RAM – SRAM & DRAM
🔹 Difference Between SRAM and DRAM
🔹 Volatile Nature of RAM
🔹 Role of RAM in Memory Hierarchy
🔹 Real-Life Examples of RAM Usage

With simple diagrams, memory access flow, and practical examples, this lecture helps you clearly understand how RAM stores data temporarily and supports fast CPU operations.

This topic is part of Unit 4 – Memory in the AKTU COA syllabus and is very important for GATE, NET, and University Examinations in Computer Science.

📚 Stay tuned for more concept-based lectures on COA, OS, DBMS, DS, TOC, Java, and Python.
