MAC ADDRESS

MAC ADDRESS: 

I know all of u r familiar with this but many of u face difficulty bout this 

Whether you work in a wired network, or a wireless one, one  

thing is common for both environments.

It takes both network software and hardware (cables, routers, etc.) to transfer data from your computer to another-or  

from a computer thousands of miles away to yours.

In the end, to get the data you  

want right to YOU, it comes down to addresses.

So not surprisingly, along with an IP address, there’s also a hardware address. Typically, it is tied to a key connection  

device in your computer called the network interface card, or NIC. 

The NIC is essentially a computer circuit card that makes it possible for your computer to connect to a network. 

An NIC turns data into an electrical signal that can be  

transmitted over the network.

Every NIC has a hardware address that’s known as a MAC, for Media Access  

Control. Where IP addresses are associated with TCP/IP (networking software),  

MAC addresses are linked to the hardware of network adapters. A MAC address is  

given to a network adapter when it is manufactured. It is hardwired or hard-coded  

onto your computer’s network interface card (NIC) and is unique to it. 

Unfortunately, a MAC address can be used by law enforcement in combination  

with Internet Service Providers, to find someone’s true location and consequently  

his identity. Further in this class I will explain how to mitigate this risk.
