Introduction to how MAC addresses work on a PC

MAC addresses are a fundamental part of how a PC works. These addresses, also known as physical addresses, are unique identifiers assigned to each network card. Being unique, they allow PCs to communicate with each other efficiently and without confusion.

A MAC address is made up of ‌6‌ groups of ‍two ‍hexadecimal digits separated by colons. For example, 00:A1:B2:C3:D4:E5. Each sextet represents an 8-bit value, which means that a MAC address has a total of 48 bits. This number of bits allows for a wide range of possible addresses, thus avoiding collisions between devices.

It is important to note that the MAC address cannot be changed, since it is recorded in the network card during its manufacture. However, there is an address called a virtual MAC address, which can be changed by the user. This address, unlike the physical address, is not unique and can be used for certain purposes, such as circumvent limitations imposed by an internet service provider.

In summary, MAC addresses are essential for the functioning of PCs and allow for efficient communication. between devices. Although the physical MAC address cannot be changed, there is the possibility of using a virtual MAC address for certain special cases. Through these unique identifiers, PCs can connect to a network and enjoy all the benefits that connectivity offers.
