Question. In how many ways can we access the internet.
Answer. ISP's provide internet in the following forms:

(ii) Broadband Connection: It is a high speed internet access. Broadband connectivity doesn't even disturb the telephone use. Its carries both voice and data over a single wire. Voice user the lower end of frequency spectrum while the data use the higher end. The same telephone line is thus, split in two separate channels. Broadband connection are measured in mbps (megabits of data per sound ).
Broadband service is available in three ways.
(a) cable modem: It is the same connection that delivers cables. TV It is fast and reliable.
(b) DSL (Digital Subscriber Line): It use an existing phone line but line for voice call remains separate.

Question. Why is Internet called ‘Network of Networks’?
Answer. Internet is called ‘Network of Networks’ because it is global network of computers that are linked together by cables and telephone lines making communication possible among them. It can be defined as a global network over a million of smaller heterogeneous computer networks. The network which consists of thousands of networks spanning the entire globe is known as Internet. The Internet is a world wide collection of networked computers, which are able to exchange information with each other very quickly.
Mostly people use the Internet in two ways, E-mail and World Wide Web. In Internet, most computers are not connected directly, they are connected to smaller networks, which in turn are connected through gateways to the Internet backbone. A gateway is a device that connects dissimilar networks. A backbone is central interconnecting structure that connects one or more networks.

Typically, the client program (browser) runs on the separate machine from that of the server. The server that care of all the issues related to document storage, whereas the task of presenting the information to the user is left to the client program.
The protocol that web client and server use to communicate with each is called the Hypertext Transfer Protocol (HTTP). All web client and server must use HTTP in order to send / receive hypermedia documents. For this reason, web server are often called HTTP servers.

Question. How did the Internet begin?
Answer. In 1969, the University of California at Los Angeles and the University of Utah were connected with the beginning of the ARPANET (Advanced Research Projects Agency NETwork) using 56 kbit/s circuits, which is sponsored by U.S. (United States) Department of Defense (DoD). The goal of this project was to connect computers at different Universities and U.S. defense.
In mid 80’s another federal agency, the National Science Foundation (NSF) created a new high capacity network called NSFnet (National Science Foundation network), which was more capable than ARPANET. The only drawback of NSFnet was that it allowed only academic research on its network and not any kind of private business on it.
Now, several private organisations and people started working to build their own networks, named private networks, which were later (in 1990’s) connected with ARPANET and NSFnet to form the Internet. The Internet really became popular in 1990’s after the development of World Wide Web (WWW).

TCP is a protocol, which is responsible for finding path for the destination. It also splits the message into several datagrams, if it does not fit in one datagram. Therefore, these datagrams are sent through different alternate paths towards the destination. The TCP makes sure that the datagram arrives at the destination correctly.
