Understanding Number Systems: Types, Concepts, and Applications
Number Systems
A number system is a way of representing numbers using digits or symbols. It consists of three components:
- Base (or Radix): The number of unique digits used in the system.
- Digits: The symbols used to represent numbers. For example, 0-9 in the decimal system.
- Place Value: The value assigned to each digit based on its position.
Types of Number Systems
- Binary (Base 2): Uses 2 digits, 0 and 1.
- Decimal (Base 10): Uses 10 digits, 0-9.
- Octal (Base 8): Uses 8 digits, 0-7.
- Hexadecimal (Base 16): Uses

Attempt all questions. (Maximum word limit: 50)
a. Why does a computer understand only binary language?
Computers understand only binary language because they operate using electrical signals, which have two states: on (1) and off (0). These two states correspond to binary digits, making binary the most efficient and reliable way to represent data and instructions electronically.
b. What are system software and application software? Give examples.
- System software: This includes programs that

What is an algorithm?
An algorithm is a sequence of unambiguous instructions for solving a problem, i.e., for obtaining a required output for any legitimate input in finite amount of time. An algorithm is step by step procedure to solve a problem.

First Order Predicate Logic (FOPL)
Definition
First Order Predicate Logic (FOPL), also known as First Order Logic (FOL), is a formal system used in mathematics, philosophy, linguistics, and computer science. It extends propositional logic by incorporating objects, predicates, and quantifiers to express statements about objects and their relationships more precisely.
Components
- Constants: Represent specific objects in the domain (e.g., Alice, 5).
- Variables: Represent general objects in the domain (e.g.
