hardverazonosítókat

Hardverazonosítókat, or hardware identifiers, are unique values assigned to hardware components within a computer system. These identifiers are crucial for the operating system and applications to properly recognize, manage, and interact with the physical hardware.

One of the most common hardware identifiers is the MAC address, or Media Access Control address. This is a unique identifier assigned to network interface controllers (NICs) for communications at the data link layer of a network segment. It is typically hardcoded into the hardware by the manufacturer.

Another important identifier is the Vendor ID (VID) and Product ID (PID). These are used to identify specific hardware devices and their manufacturers. When a new device is connected, the operating system can use these IDs to find the appropriate drivers.

The serial number is another unique identifier, usually specific to an individual piece of hardware, differentiating it from other identical components.

Processors also have unique identifiers, such as the CPUID instruction which provides information about the processor's vendor, architecture, and features.

These hardware identifiers play a vital role in system stability, driver installation, software licensing, and security. They allow for precise identification and configuration of all the components that make up a functional computer.
