Digital systems represent information using 0 and 1.
Binary uses base 2: each bit weight doubles (1,2,4,8…). An n-bit number represents 2ⁿ values. Digital circuits use two voltage levels as 0 and 1. Groups: nibble (4), byte (8), word. Hex is shorthand for four bits.
Binary 1101 = 8+4+0+1 = 13.
Binary is the language of digital circuits, so understanding bits explains how data, addresses and logic are represented.

Two to the eighth, which is 256 values, from 0 to 255 unsigned.
Electronic circuits have two stable states that are easy to distinguish, so binary is more reliable than decimal at the hardware level.
Typical applications include converting a sensor reading to binary for a microcontroller register, reading a status byte where each bit means a flag and calculating the number of states in an 8-bit address bus.
Study "Datasheets" first (topic 33 of 104 in Electronics & Embedded). It covers the groundwork this topic builds on.
MSB and LSB. Unsigned range 0 to 2ⁿ-1. Bit rate vs baud rate.
Binary 1101 = 8+4+0+1 = 13.
The next topic is "Number conversions", which builds directly on this one.
It is classed as Beginner in Electronics & Embedded (topic 34 of 104). It is an entry-level topic. It relies only on basic school mathematics and the ideas introduced earlier in this discipline.
