В чем заключается Repair MAC характеристика?
Every NIC (Network Interface Card) has a unique MAC address (Media Access Control). This applies to all types of network cards, including Ethernet cards and WiFi cards. The MAC Address is a six-byte number or 12-digit hexadecimal number that is used to uniquely identify a host on a network. All MAC addresses are hard-coded into a network card and can never be changed. However, they can be changed or spoofed in the operating system itself. Характеристика ChimeraTool
