Understanding Number Systems

Number systems are fundamental to computing and digital electronics. They are essentially methods for representing numbers using a specific set of symbols (digits). The key concept differentiating them is the base or radix, which is the total number of unique digits available in that system.

Common Number Systems Breakdown

1. Decimal (Base-10)

This is the number system we use every day.

  • Base (Radix): 10
  • Digits Used: 0, 1, 2, 3, 4, 5, 6, 7, 8, 9
  • Concept: Each digit’s position

Unit 1: Information Representation

Information representation is the method used by computers to store, process, and transmit data in a form that can be understood by electronic systems. Since computers are digital devices, all information such as numbers, characters, images, and instructions is represented internally using binary digits (0 and 1). These binary values correspond to electrical signals like ON and OFF.

Different coding techniques are used to represent various types of information efficiently
