(a) Internet Protocol (IP)
(b) Transmission Control Protocol(TCP)
b. Explain the use of channels.
ans: A channel is a medium used to carry information or data from one computer to another. These channels then connect to the Internet via routers and moderns. This way, several pathways from one system to another can be established.
c. Differentiate between a router and a modem.
ans: Routers are devices that direct Internet traffic by determining the best path to be taken, whereas modems help computers and computer networks to connect to the Internet through telephone or cable lines.
d. What is an IP address and what is its use?
ans: Each computer system on the Internet has an Internet address called an IP address. This address is used to exchange information, send or receive e-mail messages, etc.
e. Explain the process of sending data from one computer system to another.
ans: When data is passed from one computer system to another, it is broken up into pieces called packets using TCP. Each packet contains 1500 bytes or characters. IP adds the IP address of the sender and the destination to each packet so that it reaches the correct destination.
The packets are passed from one network to another until they reach their destination. At the destination, TCP reassembles the packets into a complete message. If the packets are garbled, a request s made to the sender to resend them. It is not necessary for all the packets in a single message to take the same route through the Internet or for the same message to take the same route each time it is sent. Thus, one of the technical strengths of the Internet is that if some parts of it are unavailable for communicating data, the data will still be sent through another path.
f. What do you mean by modulation and demodulation?
ans: The process of converting a digital signal into an analog signal is called modulation, and converting an analog signal into a digital signal is called demodulation
g. What do you mean by the World Wide Web?
ans: World Wide Web is an Internet-based network of servers that are interconnected through hypertext. Hypertext is a method of presenting information in which the selection of highlighted text displays more information on a particular topic. These highlighted items, called hyperlinks, allow the users to navigate from one document to another that may be located on the same or a different server. In order to navigate the Internet, one has to use a web browser software.
h. Differentiate between a website and a web page.
ans: A website is a collection of one or many related web pages, images, videos, and other digital assets hosted on a web server. Whereas, a web page is an electronic document written in the computer language HyperText Markup Language (HTML).
i. What is HTTP? Why is it required?
ans: The HyperText Transfer Protocol (HTTP) is a communication protocol used to transfer all kinds of information (text, images, sound, video, and other multimedia files) on the Web. In addition to the files in HTML as well as other formats that any web server can serve, the server contains an HTTP program that is designed to wait for HTTP requests and handle them as they arrive. Your web browser is an HTTP client, sending requests to server machines. When you enter a file request in the browser program by either opening a Web file (typing in a URL) or clicking on a hypertext link, the browser builds an HTTP request and sends it to an HTTP server on the destination server machine. The server, in turn, receives the request and after performing any necessary processing, returns the requested file to the client (i.e., a web browser) that made the request running on your computer.
j. Explain the two types of Web addressing systems with examples.
ans: The two types of web addressing systems are:
(a) Letter Addressing System and (b) Number Addressing System
(a) Letter Addressing System: The web address of any computer or network can be given using alphabets. This is called the Letter Addressing System. It is popularly known as Domain Name System (DNS). Some examples of Letter Addressing System are assam.gov.in, yahoo.com, hotmail.com, oup.com.
(b) Number Addressing System: Every TCP/IP network requires a unique network number and every host on a TCP/IP network requires a unique IP address. The number addressing system takes care of this. A numeric or IP address comprises four numbers, each less than 256, joined together. An IP address is a 32-bit number that uniquely identifies a network interface on a machine. IP addresses are written in decimal digits, formatted as four 8-bit fields, separated by periods. Each 8-bit field represents a byte of the IP address. The byte ranges from 0 to 255. For Example: 132. 168. 1. 100
