Binary Number System Basics

Binary is the foundation of computer science, using a base-2 number system with only two digits: 0 and 1. Each digit is called a "bit" and represents the smallest unit of information.

Why Do Computers Use Binary?

  • Simplicity: Electronic devices can easily represent two states (on/off, high voltage/low voltage)
  • Reliability: Binary signals are less susceptible to noise interference
  • Cost-effectiveness: Binary logic gates are simpler and cheaper than multi-value logic gates

Importance of Binary Arithmetic

Binary arithmetic is the foundation of all calculations performed by computer processors. Understanding carry and borrow concepts is crucial for programming, digital circuit design, and computer architecture.
