Click on any of the links below to start learning from Teachoo...

Do you want to learn more about one of the most important and fundamental topics in computer science? Do you want to understand how encoding schemes and number system work and how they are used to represent and manipulate data in computers? Do you want to practice and implement encoding schemes and number system using Python as a programming language?

If you answered yes to any of these questions, then you will find this chapter very useful. In this chapter, you will learn about the concept and implementation of encoding schemes and number system. Encoding schemes and number system are methods and techniques that are used to convert data into binary form that can be processed by computers. Encoding schemes and number system are used to represent and manipulate various types of data such as numbers, characters, symbols, etc.

Some of the topics you will cover in this chapter are:

• The definition and types of encoding schemes: How encoding schemes are defined and classified into different types such as ASCII, Unicode, etc. 📝👩‍🏫👨‍🎓
• The definition and types of number system: How number system are defined and classified into different types such as decimal, binary, octal, hexadecimal, etc. 📊📈📉
• The conversion of number system: How number system are converted from one base to another using various methods such as division, multiplication, substitution, etc. 💻🖱️👍
• The arithmetic operations on number system: How arithmetic operations such as addition, subtraction, multiplication, division, etc. are performed on number system using various rules and algorithms. 💬🔎👏
• The Python code for encoding schemes and number system: How encoding schemes and number system are coded and executed using Python as a programming language. 💻🐍👍

By studying this chapter, you will gain a deeper understanding of how encoding schemes and number system are essential and fundamental tools for representing and manipulating data in computers. You will also develop critical thinking skills to solve various problems and cases using encoding schemes and number system. You will also appreciate the importance of Python as a simple and powerful language for encoding schemes and number system.
