Introduction:

The world around us is filled with digital devices, from your smartphone to the traffic lights on your way to school. But have you ever wondered how these devices work and understand each other? Digital Logic Design (DLD) is like a secret language that these devices use, made up of 0s and 1s. In this chapter, we’ll unveil the basics of DLD, exploring the building blocks called logic gates and how they work together to create the digital world we live in.

DATA REPRESENTATION IN A COMPUTER:

Imagine a computer as a giant filing cabinet, but instead of papers, it stores information electronically. But how does it understand things like pictures, text, or even music? The secret lies in data representation, which is like converting all information into a language computers can understand.

Here’s the basic idea:

  • Computers only understand two states: ON (1) and OFF (0).
  • All information, from text to pictures, is converted into a series of 0s and 1s called binary code.
  • Each combination of 0s and 1s represents something different. For example, the letter “A” might be represented by the code 01000001.

This might seem complex, but it’s the foundation for how computers process and store all kinds of information you use every day!
