What is a MAC Address?

You may be thinking that this address has something to do with your computer being an Apple device.

MAC address sounds like it is related to Mac products, right? Well in the case of this tech term, it doesn’t actually have anything to do with Apple products or your MacBook specifically.

MAC is an acronym for Media Access Control. This shortened abbreviation of MAC comes into play when trying to connect your computer to a network and applies to all computers not just your MacBook Pro.

All laptops, desktops, PCs, and Macs have MAC addresses associated with them. This address comes in the form of a 12-digit code and your MacBook Pro actually has two of them. One is related to the Ethernet connection and the other for the Wi-Fi adapter.

To break it down even further, this MAC address is not specifically associated with your computer at all, but rather the network cards that are built into the machine.

And these MAC numbers can be on different devices such as phones, tablets, or any other device with the capability of connecting to a network.

Why is MAC Address Important?

The most common use of a MAC address is based on network access filtering.

This basically means that the MAC address number allows an Internet provider to have control over your access. This keeps internet access to one source in a house from a device like a modem.

MAC addresses can also be used to assign static IP addresses and filter these addresses to limit the number of device connections.

In addition to this, MAC addresses are used to identify your device at a location such as an Internet Cafe that might have a time limit on use or to track your device for reasons good and bad, depending on your opinion of having your information tracked.
