Description

Human beings use lots of languages or codes to exchange information. We can speak in different languages but we know that the information is unique, the difference is the code we are using to comunicate it. To be able to understand and use this information we need to know the rules of the code we are using, we need to know the language in which the information is transmitted.

What is the language that computers and digital systems speak? How you are going to learn in this course, digital systemos only understand data containing 1's and 0's.

We can organize the information that a digital system keep and process on numeric and non-numeric data. Along this course you will learn how it's codified the numeric information using only 1's and 0's. We will start learning to codify simple numeric integers and we will advance little by little until more complex codifications until finding the codification of rational numbers with floating-point.

Although the main part of the course "Digital number systems" is centered on numeric information we will not forget non-numeric data so you will also learn some codes for this kind of information. Besides, we will analize the error detection and correction error codes importance, studying some of these codes.

The course "Digital numeric systems" is divided into 6 blocks with more than 3 hours of video. To unsure the knowledge you are going to obtain, you can practice with the proposed exercises and with tests so you can check your level.

There is no need for the students to have a high technological level to take advantage of this course and being able to follow from the start. The students only need some mathematical basic concepts (add, subtract, multiply, division). We will start with simple concepts that will form the base to advance into more complex concepts.

Do you want to know what is the language of the computers? In this course you will start to understand it.

Who is the target audience?
  • Students with just some curiosity about computer language, from beginners to students with more computing level
