Glossary of Networking Terms
DHCP (Dynamic Host Configuration Protocol) – This basically means that IP addresses are not static, they can changed at any time. In the case of ISP DHCP, it means that your ISP can change your public IP address. In case of DHCP enabled on your router, it means that your router can change the local IP addresses of attached devices at any time.
DNS - Domain Name System is the method by which website or domain names are translated into IP addresses. Specify such an address manually, according to the information provided by the ISP. For 99% of applications you don’t have to deal with this; This parameter in the CyberQ Wi-Fi is reserved for advanced IT personnel.
Hot-spot Mode – This mode of the CyberQ Wi-Fi allows direct connection and access from mobile devices or PCs. In this mode, the CyberQ Wi-Fi actually functions as a mini Wi-Fi router, though it does not provide Internet access.
Infrastructure Mode – This mode of the CyberQ Wi-Fi links to a wireless router, providing other devices on your network access to its internal data plus features requiring Internet access.
IP Address - An IP address (Internet Protocol) address is your computer's equivalent of your postal address and just like the mail service, each computer has to have its own address so that it will only receive the information that is meant for it and not anything that is meant for someone else. Your Public IP address is the address that is assigned to you by your ISP. The Private IP addresses on your network is generally assigned to your computers and devices by your router.
ISP (Internet Service Provider) – The company that sells you internet service, i.e. Comcast, Verizon, etc.
Key – This is the encryption key. The types of encryption are shown below:
WEP - Wired Equivalent Privacy. This was the original security setting on wireless networks. In the CyberQ Wi-Fi, it must be a value containing the characters 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F (hexadecimal value). WEP 40 requires 10 Characters, WEP104 requires 26 characters.
WPA - Wi-Fi Protected Access. Provides better encryption than WEP and also has user authentication.
WPA2 - a more secure version of WPA which provides "government grade" security. There are two versions of WPA2 - Personal & Enterprise.
WPA AUTO – Automatically selects a WPA or WPA2 network
WPA or WPA2 PHRA – Uses a passphrase instead of hex values.
OPEN – No encryption. MAC Address (Media Access Control) Tthis is the ID of computers and other network devices. It never changes and is assigned to the device when it is manufactured. Each device has a unique address
Net Mask Address - Bundled with an IP address there is always a "Netmask" value. The Netmask, together with the IP address, defines the network the computer belongs to, that is which other IP addresses the computer can touch directly in the same LAN. For 99% of applications you don’t have to deal with this. This parameter in the CyberQ Wi-Fi is reserved for advanced IT personnel.
Port - Every IP address is divided up into many ports for different functions. When one computer sends data to another computer, it sends it from a port on an IP address to a port on an IP address. A port can only be used by one program at a time. The protocol used for the CyberQ Wi-Fi’s web pages is HTTP (Hypertext Transfer Protocol)
Port Forwarding - Port forwarding allows remote computers, for example, computers on the Internet, to connect to a specific computer or device within a private local area network (LAN).
Router – This is the device that manages and connects your local network to the internet. It may have a built in cable modem or you may have an external cable modem that connects to your ISP. It manages all of the local traffic on your network and also determines how data is passed back and forth between your local network and the internet.
SSID – (Service Set Identifier) is the name that identifies an 802.11 wireless LAN.
