Application Based Questions.

1. Broadband or WiMAX technology can be used to access Internet services. For using Broadband service they

need a modem and a switch to share the Internet while a WiMAX receiver is required to receive the wireless signals.

2. Do as per your available network connection.

3. Transmission Control Protocol (TCP): IT is responsible to create data packets to be sent to the source

computer. It is also responsible to reassemble the received packets at the destination computer to the original

information. While Internet Protocol (IP) assigns the address of destination computer to each packet and enroute

them over the network to their destination.

HTTP: Hyper Text Transfer Protocol is a communication protocol used by the client machine to send the request

to the web server for a web page and at the server end, it helps to transfer the requested page on the client machine.

Internet Service Provider (ISP): An ISP is a company or organization which provides access to the Internet

connectivity to the users.

IIS: Internet Information Services, a set of Internet-based services for servers using Microsoft Windows.

SMTP: Simple Mail Transfer Protocol is used to send emails on the internet.

Ans. The term data is used for the raw facts which is processed by the computer, whereas information is the processed form of data, i.e., the output produced by the computer.

Q.3. what are the four major functions of the computer system?
Ans. Input, Output, Storage and Processing.

Q.4. What are the two main characteristics of computer system?
Ans. Speed and Accuracy.

Q.5. What do you understand by diligence as a characteristic of computer?
Ans. Diligence refers to the continuous working of the computer system for long hours without getting tired.

Q.6. What are the limitations of computer system?
Ans.

• Zero IQ
• Lack of decision making power
• No learning power

Q.7. How can computers be used in the field of communication?

THE INTERNET

Q.1. What is computer Network?

Ans. Inter-connectivity of two or more computers to share information and resources among them, is called computer network.

Q.2. What is Internet?

Ans. Internet is the largest network of computers spread across the world. It is also called network of networks as it conncets millions of dissimilar networks around the world.

Q.3.What do you understand by ARPANET?

Ans. ARPANET stands for Advanced Research Projects Agency Network. This was the name of a network developed by ARPA, an agency sponsored by the US Defense Department. ARPANET was later popularised as Internet.

Q.4.What do you understand by the terms 'Backbone' and 'Gateway' in context with Internet?

Ans. An Internet Backbone is a central high speed interconnecting structure which connects the dissimilar networks whereas gateway is a special network device which connects the individual networks to the backbone such that they can communicate with each other.

Q.5. What is Client-Server technology?

Ans. This is a technique used to connect the computers in a network such that a resourceful machine called server, provides connectivity to various client machine with limited resources. The client machine sends a request for the data to the server machine and the server replies to the request by sending the requested resource to the client machine.

Q.6. What is protocol? Which set of protocols is used by the internet?

Ans. Protocols are a set of communication rules followed by the system while exchanging information with each other.

Internet uses a set of two protocols i.e., TCP(Transmission Control Protocol) and IP(Internet Protocol) to exchange the information among the connected resources.

Q.7. What is the function of a Modem?

Ans. Modem stands for Modulator Demodulator. It is a device which connects the computer to the communication lines capable of carrying analog data. Modem converts digital signals to analog at the sender's machine and analog to digital at the receiver's machine.

Q.8. Who owns the Internet? What is the role of IETF and IRTF?

Ans. Internet is not owned by any individual or organisation but it is managed by some volunteer organisation who work for the development, research and management of this network.

IETF(Internet Engineering Task Force) looks after the technical issues and development of new standards for the working of Internet whereas IRTF(Internet Research Task Force) looks after the long term research issues like Internet protocols, applications, architectures and technologies related to Internet.

Q.9. What is the different ways to connect with the Internet?

Ans. Mainly there are three different ways provided by the ISPs to connect withe the internet. These are: 

• Dial-up connection
• Broadband connection
• Wireless connection

Q.12. What is the difference between HTTP and HTML?

Ans. HTTP or Hypertext Transfer Protocol helps the browser and web server to communicate with each other whereas HTML or Hyper Text Markup Language is used to create the web pages. 

Internet, Intranet and Extranet

Internet, intranet, and extranet are three terms that describe "Internet type" applications that are used by an organization, but how do you know if a web application is part of your intranet or part of the Internet?

• INTERNET:

The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide.

• INTRANET:

An intranet is a private computer network that uses Internet Protocol technologies to securely share any part of an organization's information or operational systems within that organization.

• EXTRANET:

An extranet is a private network that uses Internet protocols, network connectivity. An extranet can be viewed as part of a company's intranet that is extended to users outside the company, usually via the Internet.

Internet	Intranet	Extranet
It is a Global system of interconnected computer network.	It is a Private network specific to an organisation.	It is a Private network that uses public network to share information with suppliers and vendors.
Not regulated by any authority.	It is regulated by an organization.	It is regulated by multiple organization.
Thus content in the network is accessible to everyone connected.	Thus content in the network is accessible only to members of organization.	The content in the network is accessible to members of organization & external members with access to network.
It is largest in terms of number of connected devices.	It is small network with minimal number of connected devices.	The number of devices connected is comparable with Intranet.
It is owned by no one.	It is owned by single organization.	It is owned by single/multiple organization.
It is means of sharing information throughout the world.	It is means of sharing sensitive information throughout organization.	It is means of sharing information between members and external members.
Security is dependent of the user of device connected to network.	Security is enforced via a firewall.	Security is enforced via a firewall that separates internet & extranet.
Example: What we are normally using is internet.	Example: TCS using internal network for its business operations.	Example: HP and Intel using network for business related operations.
Users can access Internet anonymously.	Users should have valid username/password to access Intranet.	Users should have valid username/password to access Extranet.
Internet is unregulated and uncensored.	But Intranet is regulated by the organization policies.	Extranet is also regulated by contractual agreements between organizations.
