Q.7 What is a gateway ?
A
A gateway is a term used to refer to a device or software that is used to link networks with
different standards.
For example, a gateway is needed when connecting a cell phone to the Internet or in any
case where you wish to connect two devices that are completely different. Gateway carries
with it the meaning of entrance and exit and a router may also be referred to with this term.
When making gateway settings, it is necessary to make IP address settings for the device
that will act as a gateway.
Q.8 What is a URL ?
A
A URL is an address that is written in a way so that it is easy for the DNS function to
determine on which server the IP address is located.
This address begins with "http:// " and is followed by such things as domain names, server
names, port numbers, file names and other such info.
For example, if the IP address that is assigned to "www.tandd.co.jp" is "61.197.203.107",
by entering "http://61.197.203.107/product/wdr_3/tr_7w_01feature.html" in the browser,
the same page will appear as when you enter "http://www.tandd.co.jp/product/tr_7w/
tr_7w_01feature.html".
- The DNS or Domain Name Server helps to switch difficult to understand IP address of just
numbers, such as "61.197.203.107" into easy to grasp names such as "www.tandd.co.jp" and
helps connect to the desired server.
