Subnet Mask –
The method used for dividing IP networks into small networks
called subnets. The division is determined by a binary pattern (called mask).
Based on this mask (subnet mask), IP addresses of the hosts in that subnet can
be assigned.
TCP (Transmission Control Protocol) -
A setup of rules used to transmit data
along with the IP (Internet Protocol) to split the data to be transmitted into small
pieces. TCP creates connections with its peer to send the data. The protocol
offers reliability of the packet transmission and adds delay in the network.
Applications that assume unreliable networks generally use TCP.
TCP/IP –
(Transmission Control Protocol / Internet Protocol) Set of protocols for
communications over a network developed specifically for the Internet. TCP/IP
defines a suite or group of protocols that involves many protocols like ICMP, RIP,
DHCP, etc.
Throughput –
The data sent successfully through the Internet in a given time
period.
UDP (User Datagram Protocol) -
A setup of rules used to transmit data
along with the IP (Internet Protocol) to split the data to be transmitted into small
pieces (called datagrams). UDP does not create a connection with its peer to
send the data. Hence it is “connection-less”, unreliable, but faster because there
is no connection setup delay.
Upgrade –
To replace the firmware version of the DIR-430 with a newer version.
URL (Universal Resource Locator) -
It is the address that defines the route to
a file on the Web or any other Internet resource. These can be accessed through
typing the URLs in to the browser, or by clicking the hyperlinks on the existing
web pages on the browser.
VoIP (Voice over Internet Protocol) –
VoIP is a technology that makes use of
your existing Internet connection instead of normal PSTN. When you connect your
telephone on your RGS Gateway, the voice gets converted into digital
information, which will be transmitted on the Internet. At the receiver’s end, the
reverse operation is performed.
VPN (Virtual Private Network) -
A technology with which hosts communicate
over public communication networks by creating private communication channels
called tunnels. This is mostly achieved through encrypting the traffic at the
originating point and decrypting the traffic at the destination point. Examples of
VPN technology are, PPTP (Point to Point Tunneling Protocol), L2TP (Layer 2
Tunneling Protocol), IPSec (Internet Protocol Security).
VPN end point –
A host connected to a router (or the router itself for the router
related data traffic) has the ability to establish a VPN tunnel to some other host
supporting VPN.
WAN (Wide Area Network) -
Networks that cover communication over a large
geographic area. These are through public networks like telephone (DSL) or cable
Networks, through leased lines or satellites. Internet is a Wide Area Network.
