Q & A
What is the primary function of the internet?
-The primary function of the internet is to connect computers all over the world, enabling people to share information and communicate from anywhere with an internet connection.
How is the web different from the internet?
-The web, or worldwide web, is a collection of different websites accessed through the internet, whereas the internet is the underlying network that connects these websites and other devices.
What are the main components of the internet?
-The main components of the internet include end systems (like computers and smartphones), routers and switches, communication links, internet service providers (ISPs), and protocols such as Internet Protocol (IP) and Transmission Control Protocol (TCP).
What role do web browsers play in accessing the web?
-Web browsers are software used to access the web, allowing users to view and interact with web pages and resources.
What is the purpose of web servers?
-Web servers store and serve web pages, making them accessible to users via the internet.
What is HTML and why is it important for creating websites?
-Hypertext Markup Language (HTML) is a language used for creating web pages. It is important because it structures the content and provides a framework for web design.
What are HTTP and HTTPS, and how do they relate to webpage transmission?
-HTTP (Hypertext Transfer Protocol) and HTTPS (HTTP Secure) are protocols used for transmitting webpages over the internet, with HTTPS providing a secure, encrypted connection.
What is a URL and how does it help locate web resources?
-A URL (Uniform Resource Locator) is an address used for locating web resources. It specifies the location of a webpage or other web resources on the internet.
How does the internet facilitate remote work and video conferencing?
-The internet enables remote work and video conferencing by providing a platform for global communication, data transfer, and device interaction, allowing people to work and collaborate from different locations.
What role does the web play in supporting online shopping and banking?
-The web supports online shopping and banking by providing a platform for businesses to offer their services and for customers to access and manage their financial transactions via websites.
How do the internet and the web contribute to modern ICT systems?

Outlines
π Understanding the Internet and the Web
This paragraph introduces the concepts of the internet and the web. The internet is described as a global network that connects computers, enabling the sharing of information and communication worldwide. The web, or World Wide Web, is presented as a system of interconnected websites that can be accessed via the internet. Websites consist of text, images, and other resources. The paragraph then delves into the components that make up the internet and the web, such as end systems (devices like computers and smartphones), routers and switches, communication links, internet service providers, and protocols like IP and TCP for the internet. For the web, components include web browsers, web servers, HTML for creating web pages, HTTP/HTTPS protocols for webpage transmission, and URLs for locating web resources.

Transcripts
Welcome to our video on the internet and
the web today we'll explore what they
are their components and their roles in
ICT systems let's dive in first let's
talk about the internet the internet is
a vast Network that connects computers
all over the world through the internet
people can share information and
communicate from anywhere with an
internet connection now what about the
web the the web or worldwide web is a
collection of different websites
accessed through the internet a website
is made up of related text images and
other
resources next let's look at the
components of the internet and the web
for the internet we have end systems
which these are devices like computers
and
smartphones Reuters and switches which
are devices used to forward data between
Networks
communication links which refers to
physical or wireless connections between
devices internet service providers isbs
which provide internet access protocols
which refers to the rules for data
transmission such as Internet Protocol
IP and transmission control protocol
TCP for the web the components include
web browsers which refers to software
used to access the web web servers which
store and serve web pages hypertext
markup language HTML which is a language
used for creating web pages hypertext
transfer protocol HTTP
https which refer to protocols used for
webpage
transmission uniform resource locator
URL which refer to addresses for
locating web
resources so how do the internet and the
web fit into ICT systems the internet
plays a crucial role in ICT systems by
enabling Global Communication through
email and social media supporting data
transfer and cloud computing linking
networks for device interaction and
facilitating remote work and video
conferencing the web on the other hand
provides vast information via websites
supports online shopping and banking
enables online learning and offers
streaming media and gaming in summary
the internet and the web are essential
for modern ICT systems enabling
communication data exchange and access
to information and services globally
