A lot of people have been asking & wondering about what is a MAC address & an IT address. So here’s the low down on it. MAC, Media Access Control, address is a globally unique identifier assigned to network devices, and therefore it is often referred to as hardware or physical address. To make it even simpler it’s like a person’s name. MAC addresses are 6-byte (48-bits) in length, and are written in MM:MM:MM:SS:SS:SS format. The first 3-bytes are ID number of the manufacturer, which is assigned by an Internet standards body. The second 3-bytes are serial number assigned by the manufacturer. MAC address can be thought of as supporting hardware implementation whereas IP address supports software implementation. MAC addresses are permanently burned into hardware by hardware manufacturer. Often people confuse themselves with IP address & MAC addresses. IP addresses are assigned to the network devices by a network administrator. IP address changes as the network device moves from one network to another. Okay, to make it even simpler. MAC address is your real name by which you are known. It’s your first & foremost identification. In case you’re lost the police generally post’s your photo with your name to trace you. Similarly you can trace a MAC address using special skills that you can acquires over years of yoga & meditation around computers. For IP address here’s a simple explanation. If you like to use Facebook & Twitter excessively at work place the IT guy (mean guy) can trace your usage via the IP address assigned to your machine & block certain websites, so you continue having a horrible day at work & not tweet about it to make you feel better.
