UNIT OBJECTIVES:

The Web: Lesson1: Web Browser
Lesson 1: Web
Browser

A web browser is a software program to access information on
the world wide web (usually referred to as a browser). Upon
requests by a user of a website a web page is downloaded
from a database server by the web client and the link on the
screen is shown.
A web browser is not the same as a search engine, although it
is often frustrating in both. A user is a search engine that only
contains information about other websites, including Google
Search, Bing or DuckDuckGo. Nonetheless, a user must have
a web browser installed to connect to the website server and to
view their web pages.
Web Browser

The aim of a web browser is to collector and display information
resources on the Web on the device of the user.
This cycle starts when a Uniform Resource Locator (URL),
such as https:/en.wikipedia.org, is entered by the user into the
web browser. Nearly all web-based URLs start with either http:
or https: which means the Hypertext Transference Protocol
(HTTP) is used to access the URLs. For HTTPS: the browser-
web server contact is encrypted for security and privacy
purposes.

The rendering engine of the browser displays it on the user's
device once a Web page has been found. This includes
browser-supported picture and video formats.
Hyperlinks to other pages and services are usually found in
websites. Each link has a URL and the browser navigates to the
new source when it is clicked or tapped. This restarts the
process of bringing the user content.

For later visits to the same website, most browsers use an
internal web-page cache to improve their loading times. Many
things like big images can be stored in the cache to avoid being
downloaded from the server. Cached items are usually only
stored until the HTTP reply messages of the web server.
A number of features are common to the most popular browsers.
Users can set and browse in private mode by using bookmarks.
Extensions can also be personalized and some of them provide
a sync feature.

Most browsers have these user interface features:
• Enable the user to open multiple pages simultaneously, either in
different browser windows or in various tabs in the same window.
• Go back and forth to the last page you visited or to the next one.
• Refreshing or reloading the current page button.
• To avoid loading the page with a stop button. (The pause button
is combined with the reload button in some browsers.)
• A click back to the homepage of the app.
• An address bar for entering and displaying the URL of a
website.
• A search bar for entering search engine terms. (The search bar
is fusioned with the address bar in some browsers.)

Niche browsers with different features are also available. One
example is text-only browsers that can help people with poor
Internet connections or visually disabled individuals.
A web browser is a computer-based software program that
allows users to visit their favorite websites on the Internet.
Mozilla Firefox, Google Chrome, Microsoft Edge, Apple Safari

The Web : Lesson 2: Web Links
Lesson 2: Web Links

The website is a series of websites that are published at
least on a web server. A web link or link is an HTML
(Hypertext Markup Language) object that redirects users
to a new location within the web, either by clicking or taping.
The majority of the connection can be attached via text or
photos.
There are different types of links on the Internet, both
internal and external. An internal link is a link that you see on a
web page that navigates users to another web page of the same
domain. External Links or "outbound links" are connections
that take you to another domain when browsing a specific
website.

There are also Natural Links. These are links that you obtain
from other website owner without asking for them, this is usually
done when website owners redirect their readers to your page
because your page includes material that they think is worth
sharing. Another is Manually Collected Links. These are links
you get from your own efforts, where you have to invest your time
and resources, connect with other website owners and bloggers to
link and view your page.
This also includes Broken links This is a page that says "404
error" or "The page can not be viewed."
