Briefing on Internet and Networking

Internet: The term "internet" refers to a collection of different services and information. It provides a vast amount of information in one location. It is a useful tool for researching and communicating about various kinds of topics. The Internet is a massive international source of information.

Networking: Computer networking is the term for a network of connected computers that may communicate and share resources. These networked devices communicate data through wireless or physical technologies using a set of guidelines known as communications protocols.

Network Protocol

An established set of guidelines that govern how data is sent between various devices connected to the same network is known as a network protocol. 

In essence, it enables interconnected devices to interact with one another despite any variations in their internal workings, structures, or designs.

The quickest protocol is Net BIOS Enhanced User Interface (NetBEUI), and it doesn't need any special settings to use it. The use of NetBEUI is straightforward. 

A routable protocol called AppleTalk is primarily used on networks to connect Macintosh machines.

Another routable protocol is Transmission Control Protocol/Internet Protocol (TCP/IP). The majority of OSs support TCP/IP. It is more trustworthy than alternative protocols. 

In Novell NetWare networks, NWLink is utilized. This protocol may be routed and is simple to deploy. Compared to TCP/IP, the NWLink protocol is quicker, although it is slower than NetBEUI.

Advantages of the Internet

1. Sending Electronic Mail (email)

Email on the Internet.

The majority of people use the internet for email. Email is used by people to send data, images, videos, business communications, and other information to others immediately. People were able to interact more swiftly as a result, which also improved business efficiency. An email has greatly reduced the quantity of paper needed and lessened the strain on the established postal system.

2. Accessing E-Commerce

E-commerce on the Internet.

The Internet makes it feasible for goods and services to be sold online. Many providers of e-commerce platforms, such as Amazon and Ola, gather a range of products and services available on the market and make them available for purchase to customers through their portal. Customers may skip visiting physical businesses and get a good price on these websites.

3. Searching Information

Searching for Information on the Internet.

Information can now be found much more easily with the advent of the internet, and it only takes a few clicks to find what you need. These search engines get the data a user requests from any server, wherever it may be in the world (world wide web). Google, Yahoo, and MSN are the three most well-known search engines currently in use. Any subject may be searched on this website. Nowadays, the term "Google" is widely used to replace the verb "search."

4. Performing Banking Online

Banking on the Internet.

Performing online banking is referred to as Net banking, and it makes it possible to carry out basic financial activities on a mobile device or at home. Bank branch visitation has considerably declined since virtually all services are now available 24 hours a day via net banking. Any amount of money can be moved instantaneously with this option. E-banking is also supported for payments for services like electricity, telephone, and other utilities.

5. Online Education

Education on the Internet.

The Internet offers a wide range of educational materials on a variety of topics. People only need to spend a few minutes online researching the relevant subject. The Internet offers a range of educational materials on any subject with well-organized navigation and search possibilities. Since everyone can search the internet for any book they want to read from any server anywhere in the world, people don't need to go to libraries to peruse books. 

Those who are unable to attend in-person lessons may sign up for an online course where they may communicate with their instructor through video from a different part of the world and learn about the subject using various audiovisual aids.

Summary

Thousands of smaller networks are connected by the global communication network known as the Internet. A network of linked computers that can interact and share resources is known as a computer network. A network protocol is a collection of rules that have been designed to control how data is transferred between different devices connected to the same network. The Internet enables human interaction through social media, electronic mail (e-mail), "chat rooms," newsgroups, and audio and video transmission while also enabling remote teamwork. It supports a variety of applications, such as the World Wide Web, that require access to digital information.

Solved Questions

1. How to identify a Protocol?

Ans: You can Identify protocol by following these steps:-

• To identify a Protocol, you can first select Settings, then open the Control Panel from the Start menu.

• Double-click Network to launch the Network control panel when the Control Panel is visible. 

• Examine the Protocols tab to see if NetBIOS, NetBEUI, TCP/IP, or LANBIOS (or LANtastic if you utilize a LANtastic network) is indicated.

2. For what NetBEUI is designed?

Ans: A network service called NetBIOS (Network Basic Input/Output System) makes it possible for programs running on various computers to communicate with one another via a local area network (LAN). It was created in the 1980s to be used with early IBM PC networks.
