1. INTERNET

2. MEANINING OF INTERNET
the word internet means an electronic communications network that
connects computer networks and organizational computer facilities around
the world —used with the except when being used attributively.
Or in other words
The internet is a globally connected network system facilitating worldwide
communication and access to data resources through a vast collection of
private, public, business, academic and government networks. It is governed
by agencies like the Internet Assigned Numbers Authority (or IANA) that
establish universal protocols.
Inter means international and net means network. It means that internet is a
international network.

3. WHY DO WE NEED INTERNET
The world without the internet is unimaginable. That’s why the
importance of the internet should be discussed. Our daily life tasks,
communication, and enjoyment depend chiefly on the internet. As per
its definition, the internet connects users with different types of mobile
phones and computer systems.
The sharing and exchanging of ideas, information, and news all need an
internet connection. The internet connects computers and businesses,
people, government schemes, lives, and stories worldwide.

4. IS INTERNET A NEED OR A WANT
Internet may be a need for you . However, if you only use your home internet
for entertainment, such as browsing social media or playing video games, it
is actually a want.
But people think it’s a need.
Our daily life tasks, communication, and enjoyment depend chiefly on the
internet. As per its definition, the internet connects users with different
types of mobile phones and computer systems. The sharing and exchanging
of ideas, information, and news all need an internet connection.

5. THE USE OF INTERNET
It supports human communication via social media, electronic mail,
“chat rooms,” newsgroups, and audio and video transmission and
allows people to work collaboratively at many different locations. It
supports access to digital information by many applications, including
the World Wide Web.

6. WHO INVENTED INTERNET
Computer scientists Vinton Cerf and Bob Kahn are credited with
inventing the Internet communication protocols we use today and the
system referred to as the Internet.
In response to this, other networks were created to provide
information sharing. January 1, 1983 is considered the official birthday
of the Internet. Prior to this, the various computer networks did not
have a standard way to communicate with each other.

7. TYPES OF INTERNET
There are mainly two types of internet. The age-old dial-up internet
connection, which has become almost irrelevant today, and broadband.
Broadband covers all the different types of internet connection types
that we will be discussing and includes DSL, Cable, Fiber Optic, and
Satellite.
There are many types of internet connections.

8. WWW (WORLD WIDE WEB)
The World Wide Web—commonly referred to as WWW, W3, or the
Web—is an interconnected system of public webpages accessible
through the Internet. The Web is not the same as the Internet: the Web
is one of many applications built on top of the Internet.
World-Wide Web (also called WWW or W3) is a hypertext-based
information system. Any word in a hypertext document can be
specified as a pointer to a different hypertext document where more
information pertaining to that word can be found.

9. ISP (INTERNET SERVICE PROVIDER)
Internet service provider (ISP), company that provides Internet connections
and services to individuals and organizations. In addition to providing access
to the Internet, ISPs may also provide software packages (such as browsers),
e-mail accounts, and a personal Web site or home page.
The term Internet service provider (ISP) refers to a company that provides
access to the Internet to both personal and business customers. ISPs make it
possible for their customers to surf the web, shop online, conduct business,
and connect with family and friends—all for a fee. ISPs may also provide
other services including email services, domain registration, web hosting,
and browser packages.

10. URL (UNIFORM RESOURCE LOCATERS)
A URL (Uniform Resource Locator) is a unique identifier used to locate a
resource on the Internet. It is also referred to as a web address. URLs
consist of multiple parts -- including a protocol and domain name --
that tell a web browser how and where to retrieve a resource.
End users use URLs by typing them directly into the address bar of a
browser or by clicking a hyperlink found on a webpage, bookmark list,
in an email or from another application.

11. COMERCIAL ONLINE SERVICE
A commercial online service is a service that offers a nationwide
computer network (so that subscribers can dial-in to a local telephone
number), and provides extensive and well-organized content within its
own proprietary computer network.
An online service is an entity that provides access to various types of
data for different uses via the Internet. Examples of online services
include online banking, educational, news, shopping, dating, computer
help sites, social media networks, and e-mail.

12. FREENET
Freenet is a peer-to-peer platform for censorship-resistant, anonymous
communication. It uses a decentralized distributed data store to keep
and deliver information, and has a suite of free software for publishing
and communicating on the Web without fear of censorship.
FreeNet is an ad-supported Internet product available to anyone in the
Buckeye Broadband service area. FreeNet gives you access to your
favorite online activities like email, social media, and surfing with a
speed of 2 Mbps for downloads and 1 Mbps for uploads, plus Unlimited
Data.

13. FIREWALL
A Firewall is a network security device that monitors and filters
incoming and outgoing network traffic based on an organization's
previously established security policies. At its most basic, a firewall is
essentially the barrier that sits between a private internal network and
the public Internet.
Firewalls provide protection against outside cyber attackers by
shielding your computer or network from malicious or unnecessary
network traffic. Firewalls can also prevent malicious software from
accessing a computer or network via the internet.

14. IP ADDRESS
An IP address is a unique address that identifies a device on the
internet or a local network. IP stands for "Internet Protocol," which is
the set of rules governing the format of data sent via the internet or
local network.
In essence, IP addresses are the identifier that allows information to be
sent between devices on a network: they contain location information
and make devices accessible for communication. The internet needs a
way to differentiate between different computers, routers, and
websites. IP addresses provide a way of doing so and form an essential
part of how the internet works.

15. FTP (FILE TRANSFER PROTOCAL)
File Transfer Protocol (FTP) is a widely used network protocol for
transferring files between computers over a TCP/IP-based network,
such as the internet. FTP lets people and applications exchange and
share data within their offices and across the Internet.
An FTP server is a computer program that is built to handle data
transfer between computers. The server waits for clients to connect to
it and issue commands that tell the server to upload, download, or list
directories. The FTP protocol is the commands the FTP server uses to
accomplish this.

16. HTML (HYPER TEXT MARK-UP LANGUAGE)
HTML (Hyper Text Markup Language) is the most basic building block of
the Web. It defines the meaning and structure of web content. Other
technologies besides HTML are generally used to describe a web page's
appearance/presentation (CSS) or functionality/behavior (JavaScript).
HTML (HyperText Markup Language) is the code that is used to
structure a web page and its content. For example, content could be
structured within a set of paragraphs, a list of bulleted points, or using
images and data tables.

17. HTTP (HYPER TEXT TRANSFER PROTOCOL)
Hypertext Transfer Protocol (HTTP) is an application-layer protocol for
transmitting hypermedia documents, such as HTML. It was designed for
communication between web browsers and web servers, but it can also
be used for other purposes.
The Hypertext Transfer Protocol is an application layer protocol in the
Internet protocol suite model for distributed, collaborative, hypermedia
information systems

18. HTTPS (HYPER TEXT TRANSFER PROTOCOL
SECURE)
Hypertext Transfer Protocol Secure (https) is a combination of the
Hypertext Transfer Protocol (HTTP) with the Secure Socket Layer
(SSL)/Transport Layer Security (TLS) protocol. TLS is an authentication
and security protocol widely implemented in browsers and Web
servers.
Hypertext Transfer Protocol Secure is an extension of the Hypertext
Transfer Protocol. It is used for secure communication over a computer
network, and is widely used on the Internet. In HTTPS, the
communication protocol is encrypted using Transport Layer Security or,
formerly, Secure Sockets Layer.

19. ANTIVIRUS
An antivirus product is a program designed to detect and remove
viruses and other kinds of malicious software from your computer or
laptop. Malicious software - known as malware - is code that can harm
your computers and laptops, and the data on them.
The main function of an antivirus is to scan, detect, prevent and
remove any existential threat to the computer system. Examples:
Norton, McAfee and Kapersky.

20. PROXY SERVER
A proxy server is a system or router that provides a gateway between
users and the internet. Therefore, it helps prevent cyber attackers from
entering a private network. It is a server, referred to as an
“intermediary” because it goes between end-users and the web pages
they visit online.
Proxy servers work by facilitating web requests and responses between
a user and web server. Typically, a user accesses a website by sending a
direct request to its web server from a web browser via their IP
address. The web server then sends a response containing the website
data directly back to the user.

21. WHAT IS A SERVER
In computing, a server is a piece of computer hardware or software
that provides functionality for other programs or devices, called
"clients". This architecture is called the client–server model.
Server, network computer, computer program, or device that processes
requests from a client (see client-server architecture). On the World
Wide Web, for example, a Web server is a computer that uses the HTTP
protocol to send Web pages to a client's computer when the client
requests them.

22. SEARCH ENGINE
A search engine is a web-based tool that enables users to locate information
on the World Wide Web. Popular examples of search engines are Google,
Yahoo!, and MSN Search. Search engines utilize automated software
applications (referred to as robots, bots, or spiders) that travel along the
Web, following links from page to page, site to site. The information
gathered by the spiders is used to create a searchable index of the Web.
A search engine is a software system that is designed to carry out web
searches. They search the World Wide Web in a systematic way for particular
information specified in a textual web search query. The search results are
generally presented in a line of results, often referred to as search engine
results pages.

23. WHO INVENTED SEARCH ENGINES
Until Alan Emtage, a native of Barbados, created the world's first search
engine that he called Archie. In 1989, Emtage was a systems
administrator in the information technology department at McGill
University in Montreal while he was enrolled graduate school at the
University.
The first tool used for searching content (as opposed to users) on the
Internet was Archie. The name stands for "archive" without the "v"., It
was created by Alan Emtage computer science student at McGill
University in Montreal, Quebec, Canada.

24. WHO INVENTED GOOGLE
Google, in full Google LLC formerly Google Inc. (1998–2017), American
search engine company, founded in 1998 by Sergey Brin and Larry
Page, that is a subsidiary of the holding company Alphabet Inc.
Google has its origins in "BackRub", a research project that was begun
in 1996 by Larry Page and Sergey Brin when they were both PhD
students at Stanford University in Stanford, California.

25. GOOGLE
Google LLC is an American multinational technology company that
focuses on artificial intelligence, search engine, online advertising,
cloud computing, computer software, quantum computing, e-
commerce, and consumer electronics.
Google's mission is to organize the world's information and make it
universally accessible and useful. That's why Search makes it easy to
discover a broad range of information from a wide variety of sources.

26. YOUTUBE
YouTube is an American online video sharing and social media platform
headquartered in San Bruno, California. It was launched on February
14, 2005, by Steve Chen, Chad Hurley, and Jawed Karim. Owned by
Google, it is the second most visited website, right after Google itself.
YouTube was originally created as a platform for anyone to post any
video content they desired. It was hoped that users could use the site
to upload, share, and view content without restriction. It has since
grown to become one of the foremost video distribution sites in the
world.

27. SOCIAL MEDIA PLATFORMS
A system for disseminating information over the Internet to a selected
group of followers. Social media platforms are used by people to
publish their daily activities, comments and photos as well as re-publish
information posted by others. The two major social media platforms
are Facebook and Twitter.
In today's society, the use of social media has become a necessary daily
activity. Social media is typically used for social interaction and access
to news and information, and decision making. It is a valuable
communication tool with others locally and worldwide, as well as to
share, create, and spread information.
