| Let us come to the point,
what is Internet? |
| |
Home Connects to a network..
 | Consider
that your home with few PCs were connected to another network (understand
that network is your ISPs network where millions of your ISPs customers
all connect to) through a modem or a basic router. |
Your office connects to a network..
| Consider your office networks with few hundred PCs
were connecting to the same ISP for Internet access of employees. |
ISPs (Internet service providers) connects
to a network..
| Understand some country’s have thousands of ISPs.
Each having many millions of customers connecting to them. |
IPPs ( Internet presence providers) connect
to a network..
| Now understand IPPs (Internet presence providers –
these are companies who host websites, run e-mail servers etc... Sometimes
ISPs and IPPs may be the same). |
| Understand that there are thousands of such IPPs in
the world who connect to the same network where the ISPs were connecting
to. |
Large Universities connect to the same
network..
| Understand there are large university’s with
thousands of computers, servers, web servers (we will explain web server
little later), e-mail servers etc… and they connect to the network where
ISPs and IPPs connect too. |
| Now we have a network where millions of PCs,
thousands of web servers, e-mail servers, ftp (file transfer protocol)
servers, database servers, security equipment like firewalls, all
connected together in a network. |
| Millions of network equipment connects all the above
said servers and PCs together. |
| This interconnection is distributed across
continents, countries, cities, small villages and the whole of the globe. |
| Now we come to the answer for our question, what is
Internet? |
The above illustrated, interconnected, massive, global,
network of computer equipment is called the Internet.
