Every device you buy today boasts of one or more ways to network it. however, not all of us are as comfortable with networking terms. We hope this will help...

CAT: CAT5/CAT6 are fifth and sixth generation Ethernet twisted pair cable standards defined by the Electronics Industries Association and Telecommunications Industry Association (EIA/TIA). CAT has nothing to do with felines.

Usage: Someone brought a cat to the office, but unfortunately the cat had a liking for CAT cables. Now we're planning on implementing a WLAN!

Network Address: A network address is a unique identifier for a computer on a network. Computers determine the addresses of other computers on the network and then use these to send messages to each other. An example of a network address is the Internet Protocol (IP) address, or the Media Access Control (MAC) address.

IP: An IP address uniquely identifies computers on a network. It can be private, for use on a LAN, or public, for use on the Internet. IP addresses can be assigned as static IPs (by a system administrator) or dynamic IPs (on demand, automatically, by another device on the network).

MAC: Device manufacturers permanently burn a Media Access Control (MAC) identification into networking devices, so that they can be identified easily. Using a MAC address authentication, computers can ensure that they connect to the right destination everytime, preventing fake devices from claiming to be the destination for data.

Usage: There was a hack attempt recently, some guy got hold of a networked IP address on our WLAN. He then used that address to spoof himself and identify with the WLAN and started deleting files at random. Chaos ensued, but our systems engineer used a lookup to find his MAC address, which we then traced to his internet IP address. His current address is jail!
