Free Courses : Intro to Computer Organization, Number & Data Representation

When purchasing a new computer, have you wondered what "3," "5," and "7" mean in Core i3, i5, or i7? (Hint: these are not the number of cores in the processor!) Did you know that when comparing two floating point variables, using the "==" in your programs may return False even though the variables are expected to be equal? ("==" is not the best way to compare two float variables!) Did you know that a naive statement like i++ could lead to an overflow in your C++ program? Learn the explanations to these and many more intriguing questions in this course!

Ace data representation, number representation, twos complement, IEEE floating point representation, binary arithmetic questions in competitive exams, job interviews, and computer organization and architecture course exams. Genuinely understand the representation of various kinds of data (including integers, real numbers, negative numbers, characters, images, and sound) in modern computers.

Specifically, the course will cover the following in detail.
