Description

The main goal of this course is to teach the basics of Number System and how values are represented in the memory of computer. This is very basic knowledge that any programmer/ Computer Science student must posses. This course is to help all those aspiring programmers to build their sound fundamentals with Number System.

You will learn:

**Basic concept of Number System.****Standard number systems - Octal, Hexadecimal, Binary.****How to convert number from any of these system to decimal and vice versa.****1s and 2s complement technique. Negative number representation using 2s complement technique.****How subtraction is done using 2s complement in the memory.****Real number representation using IEEE 754 standard.**

*Please do not enrol if you are:*

**Not interested of doing basic math calculations using pen and paper.****Expecting representations using graphics and animation, I did all the writings on the white board. They are really easy to understand.**

Feel free to ask questions in the Q/A section, you will find me always with you during the learning process.

Happy learning!

Who is the target audience?

- Those who wants to pursue a career in Computer Science or Electronics, particularly as a programmer or research scholar.
- Who wants to have a good understanding of how values are represented in memory of computer.
- All students who wants to understand different number system.
- All students who wants to understand how real numbers are represented in the memory using IEEE 754 standard.

Quiz 7

2 questions

Learn how to add 2 octal numbers. You will find that the procedure is just same as we follow while adding 2 decimal number only in case of Octal the base is 8 so we need to take carry when sum of columns are >=8.

Procedure for adding Octal numbers.

02:48

Test your skill on the procedure of adding octal numbers,

Quiz 8

2 questions

Let us understand how we can subtract one Octal number from another just using the naive method, we will follow the same procedure as we do while subtracting decimal number here only the change is the base, instead of 10 it is 8, we will need to take borrow of 8 from left column when the digit of subtrahend is less than the minuend.

About the Instructor

Programming Instructor with 14+ years of experience

Hi, I have been teaching computer science and programming since 2001. I did my **M Tech in Computer Science** and remained visiting faculty to the CSE department of Narula Institute of Technology. I have my own training institute where** I provide training on various programming languages and technologies to the B Tech students on C, C++, Java, Android programming, Data structure and Algorithm, DBMS, SQL and PL/SQL.**

In my class room I usually teach 100-150 students per semester on different subjects. With the udemy platform now it is possible to teach and spread my knowledge to thousands (may be more)of students across the globe, Udemy opens up vast opportunity for instructor like me and that with remuneration. I guess it's going to be a fantastic.

When I am not taking class I enjoy learning some new technologies. In my leisure time one could find me enjoying with my kids or gossiping with my beautiful wife over a container of tea. I am a **"tea-totaller"** (guess the meaning :) ) and hate smoking. I have a definite plan to launch an online course on topic **"How to drink tea - the best way"** on udemy for sure and also on **"How to quit smoking - the best way"**.

Let's hope for the best, happy learning.
