24/september/2019 Notes This date we begin the fourth period, what nerves! From now on the whole blog will be in English and to start we have a task: what are digital systems?, numerical systems... and etc. What is a numerical system? Basically it is the set of symbols and rules that are used to represent numerical data or quantities BINARY NUMBERING SYSTEM. This base 2 system is the easiest of all to have only two digits, was introduced by Leibniz in the 17th century, it is the system that they use internally the digital circuits that configure the hardware of current computers. The two digits, called bits (Binary Digit Contraction), are the one (1) and the zero (0), so the decimal equivalent will be obtained by adding the weights corresponding to bits 1. In most significant bit (MSB) is the one that is located more to the left (the one with the highest value). The least significant bit (LSB) is the one that is more to the right
