2.  The Definition On Google is: The Internet is a global system
of interconnected computer networks that use the
standard Internet protocol suite (TCP/IP) to link several billion
devices worldwide.
 My Definition Of The Internet is: A computer made system
which allows humans from all around the world to connect
and interact with each other wherever and whenever they like.
 There are various Internet web browsers which allow us to
chat with other people or to find out information about
something. Different web browsers include: Google Chrome,
Bing, Safari and many others. These web browsers are among
the most popular and most used web browsers in the world.
Personally I prefer Google Chrome as it is faster, has various
customization options, Safe and easier.

3.  A domain name is very similar to an address forwarding
service. The domain name is the address people type in their
web browser to get to your web site. The domain name then
points to the "real" address that contains your web site. The
"real" address is called the IP address and is a series of
numbers. The reason we use domain names instead of IP
addresses is because for most people a name, rather than a
series of numbers, is much easier to remember. So, your
domain name points to your IP address, which in turn points
to your web site which allows users all across the Internet to
view your web pages.

4.  Packet switching and circuit switching are two networking
methods for transferring data between two nodes or hosts.
For a packet-switched network, data is transferred by
dividing the data into individual packets and passing it
through the circuits to the other host. In packet-switched
networks, the route is not exclusively determined when the
packets hit the wire. Using routing algorithms, each packet
may actually take a different route through the network to
arrive at the destination host. Unlike a circuit-switched
network where a static route is setup and pre-established
prior to initializing connections to the host.

5.  A router is defined as a device that selects the best path for a
data packet to be sent from one computer network to
another. A router is located at any gateway (where one
network meets another), and is often included as part of a
network switch.
 How routers work
Electronic messages sent between computer networks are
stored in the router, while it determines all of the possible
paths to the destination address. The router then chooses the
most expedient route, based on its investigations into the
traffic load, distance, number of network points that the
packet has to pass through, and cost algorithms between
computer networks, before forwarding the packet to the final
destination. PTO
