• Private IP Address - An IP address for a resource in your
network that is not known or published outside the zone (for
example LAN) where it is located.
• Public IP Address - An IP address for a resource in your
network that is published outside your network to the WAN.
• Router - A device that routes data between networks through IP
address information in the header of the IP packet. A router
forwards packets to other routers until the packets reach their
destination. The Internet is the largest example of a routed
network.
• SSID - A Service Set Identifier is a unique string of characters
that identifies a wireless network
• Subnet - A portion of a network. Each subnet within a network
shares a common network address and is uniquely identified by a
subnetwork number.
• Subnet Mask - A 32-bit number used to separate the network
and host sections of an IP address. A subnet mask subdivides an
IP network into smaller pieces. An example of a subnet mask
might be 255.255.255.248 for subnet with only eight IP
addresses.
• TCP/IP - Transmission Control Protocol/Internet Protocol is the
basic communication protocol of the Internet. It supports sending
information in packets, and identifies each device with a unique
numeric IP address.
• VPN - A Virtual Private Network is a virtual network that encrypts
data and sends it privately over the Internet to protect sensitive
information.
• WAN - A Wide Area Network is a geographically distributed
network composed of multiple networks joined into a single large
network. The Internet is a global WAN.
• WLAN - A Wireless Local Area Network is a LAN with wireless
connections instead of physical connections.
