What is the MAC address?

Access control address or MAC address is a unique code assigned to each hardware that connects to the Internet. Phones capable of the Internet, network interface cards for desktop computers or laptops, wireless access cards, and even some memory cards are devices that are assigned MAC addresses. The code will be unique for each device, even two devices of the same type.

MAC address consists of six pairs of hexadecimal numbers. The numbers are separated by Colons as in the following example:

6E: 51: F5: C1: 11: 00

MAC Addresses are used in the OSI hardware model layer to pass the packets directly between the network devices. This helps to ensure that the data is sent to a physical device before decoding and/or manipulated by Device.

MAC Address is a similar IP address that the device also accepts in ensuring that each device is unique and allows you to pass data between hardware permanagement. The IP address allows two devices to communicate across the LAN or network environment - normally IP addresses should also be unique and allow data to replace.

After assignment, the MAC address is used to ensure that each device connected to a LAN or other network is unique. With a recent progress in wireless network technology, the address from the wireless card can be entered on the configuration pages for the wireless router of the network. From there, the router can either allow or reject the device to connect based on its MAC address. This can provide additional security for the network.

Many people who use network devices will never need MAC address to use devices. Some service provokers will require the device address to ensure that those who pay or are logged in to the service are the only users to connect. If that is the case,The MAC address can usually be found on the sticker on the device. If the device is portable, it can be printed inside the battery compartment.
