 +==== MAC Addresses ====
 +Written in hexadecimal notation, composed of 12 digits, the first 6 correspond to the **O**rganizational **U**inque **I**dentifier (**OUI**) and the last 6 are given by the manufacturer to each device. Every MAC address should be **unique**.
 +
 +Large manufacturers may have many several OUI.

 +===== Glossary =====
 +
 +  ***DOS :** **D**isk **O**perating **S**ystem
 +    *//The ancestor to Windows.//
 +
 +  ***HAL :** **H**ardware **A**bsraction **L**ayer
 +    *//Used in virtualization technology.//
 +
 +  ***MAC :** **M**edia **A**ccess **C**ontrol
 +    *//Unique identifier for any network device.// [[network:start#mac_addresses|See here.]]
 +
 +  ***NAT :** **N**etwork **A**ddress **T**ranslation
 +    *//Allows the translation of multiple local private addresses into a single public IP. Used in most home routers.// [[https://www.comptia.org/content/guides/what-is-network-address-translation|More info]]
 +
 +  ***NTFS :** **N**ew **T**echnology **F**ile **S**ystem
 +    *//A file system used by Windows.//
 +
 +  ***OUI :** **O**rganizational **U**nique **I**dentifier
 +    *//First part of the MAC address used to identify the manufacturer.//
 +
 +  ***SSID :** **S**ervice **S**et **Id**entifier
 +    *//Name used to identify it wireless networks from one another.//
 +
 +  ***WAN :** **W**ide **A**rea **N**etwork
 +    *//Large network not tied to a single location but spread across several locations.// [[https://www.comptia.org/content/guides/what-is-a-wide-area-network|More info]]
 +===== Upcoming =====
 +
 +  *Define kernels
 +  *Expand upond Topology (architectures)
 +  *List IANA somewhere (assigns IP addresses to the network and ensures their unicity)
 +  *Expand upon private IP addresses reserved (p. 50)
 +  *Talk about firewalls and Stateful Packet Inspection
 +  *Detail WAN/MAN/LAN
 +  *Detail NIC & MAC
 +  *Expand protocol / topology / deterministic
 +  *Compare hub vs switches
 +  *CSMA/CD
 +  *Ethernet Frame
 +  *Class of IP addresses
 +  *wired vs wireless (cite 3 advantages of each)
