Introduction to Computer Operations
Unlock Audio Lesson
Today, we’ll explore how computers fetch and execute instructions. Can anyone tell me what fetching means?
Does it mean getting the instruction from the memory?
Exactly! So, when we fetch an instruction, we locate it in memory. What do we do after fetching?
We execute it!
Right! Now, if an instruction needs data, how do we handle that?
We have to fetch that data from memory too, right?
Great job! This process of fetching and executing can be remembered as F/E for Fetch and Execute. Let's move on to the history.
Historical Figures

Computer technology has evolved significantly over the years, starting from manual mechanisms to highly advanced systems today. This has enabled us to solve complex problems with the help of computers.
Detailed Explanation
The evolution of computers began with very basic mechanical devices, progressing through various tech developments like vacuum tubes, transistors, integrated circuits, and microprocessors. Each generation has brought us closer to the highly advanced systems we use today, enabling us to handle much more complex problems efficiently.
Examples & Analogies
Think of computer evolution like the growth of a tree. Initially, it starts with a small seed (mechanical calculators), gradually developing into a robust trunk (vacuum tubes and transistors) and then branching out into many leaves (integrated circuits and microprocessors) that help it flourish in a lush environment.
Generational Changes in Technology

The first generation of computers used vacuum tubes, while transistors marked the beginning of the second generation. The third generation was represented by integrated circuits (ICs) and microprocessors came to form the fourth generation, finally leading to the fifth generation which focuses on Very Large Scale Integration (VLSI).
Detailed Explanation
Each generation in computer technology reflects a significant leap in how we build machines. The first generation relied on vacuum tubes, which were bulky and generated a lot of heat. The transition to transistors made computers smaller and more efficient. Integrated circuits in the third generation compacted many transistors into a single chip, and microprocessors revolutionized computing by integrating the CPU onto a single chip. The fifth generation focuses on even more integration, where VLSI technology allows for millions of transistors on a single chip, vastly increasing the computation power available in portable devices.
Examples & Analogies
Consider how mobile phones have evolved. The very first mobile phones were large and heavy like early computers. Then they became smaller and smarter as technology progressed, similar to how generations of computers evolved. Today’s smartphones, which incorporate VLSI technology, fit powerful computers in the palm of your hand.
Moore's Law

Moore's Law, observed by Gordon Moore in 1965, states that the number of transistors on integrated circuits doubles approximately every two years, leading to advancements in computing power.
Detailed Explanation
Moore's Law has been a guiding principle in the semiconductor industry. It predicts the continuous increase in performance and capability of microprocessors, as manufacturers find ways to fit more transistors into the same space. This trend has allowed for increasingly powerful computers at a lower cost and has driven rapid advancements in technology.
Examples & Analogies
You can think of Moore's Law like the growth of a school. Imagine a school that admits double the number of students every couple of years without needing more resources. The facilities (like classrooms and equipment) become more efficient at handling this growth, just as technology advances to handle more processing power through smaller and more effective designs.
