UNIT OBJECTIVES:

The Web: Lesson1: Web
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
and the Opera browsers are among the most popular browsers
today.

Mozilla Firefox is a free, open-source web
browser developed by Mozilla Foundation
and its Mozilla Corporation subsidiary (the
Mozilla Firefox Quantum or simply Firefox).
It operates on common systems like
Windows, MacOS, Linux and Android.
Firefox can add or remove browsing
features and allows users to tailor Firefox to
their needs. This has been done to make it
safe and easy to use Firefox.
Mozilla Firefox

Features such as tabbed browsing, spell
checking, gradual searching, live-
bookmarking, Smart Bookmarks, a
download manager, private browsing,
Google-based location-ware browsing, and
a built-in search feature.
Mozilla Firefox

Extensions allow the user to add or change
new things to the browser. They have been
created by other users. Because extensions
can access all parts of Firefox 's computer,
extensions could be created which could
harm a computer. However, only if you have
administrator privileges can the extension
change system settings.
Mozilla Firefox

Firefox also has topics or skins that alter the
browser's user appearance. Some themes,
such as Internet Explorer and Netscape, can
make Firefox look like other browsers.
Browsing tabbed is a browser feature used
by many webpages, where labelled tabs top
up to the webpage can be opened in a
window. Type control-T to make a new blank
tab.
Mozilla Firefox

In the top right corner of the window there is
a search box in Firefox that can be seen.
The browser uses a search engine, such as
Google or Yahoo, when someone with
Mozilla Firefox types something into the
search box and presses enter. Firefox 2
contains "search recommendations." The
suggested words will be displayed when
words are entered in the search box. The
browser suggests for example, "Wikipedia,"
if "wiki" is typed.
Mozilla Firefox

If a word is wrong in a text box, like the one
in which someone changes a Wikipedia
page, Firefox can use the spell check, the
program emphasizes the word wrongly
spelled on a red line. Mozilla Firefox will list
words using the right orthographer when you
scroll over that word and copy the right one.
For instance, "chekc" would have a
suggestion for the wrong word "checkc."
Mozilla Firefox

Google Chrome is a Google-developed
cross-platform web browser. It was released
for Microsoft Windows in 2008, and later
ported to Linux, MacOS, Android and iOS.
The browser is also Chrome OS's main
component, and is used as an applications
portal.
Google Chrome

Most of the source code for Chrome comes
from the free open-source Chromium
software project, but it is licensed to Chrome
as a proprietary freeware. WebKit was the
original renderer, but eventually Google
forced the renderer to build the Blink motor;
all Chrome versions except the iOS now use
Blink.
Google Chrome

Google Chrome has a simple user interface,
which is later introduced in other browsers
using its user interface concepts. The fusion
of the address bar in the omnibox, for
example. Chrome also has a good browser
reputation.

Microsoft Edge is a web browser that has
been created by Microsoft. It was first
released on Windows 10 in 2015. It
replaces Internet Explorer (IE), a browser
that was originally created on Windows 95
and which for two decades was part of
Windows operating systems.
Microsoft Edge

Edge is a smaller browser optimized for
Web service and based on web standards.
Microsoft does not currently plan to add
Edge to previous Windows versions, or to
supply versions of non-Windows operating
systems.
Microsoft Edge

Edge has reduced the bloat that most
modern browsers, including IE, have had;
Active-X support has also been reduced.
Edge was called the code in development
"Spartan," which refers to a lightweight
browser structure designed to make Edge
work on multiple device platforms, often
mobile.
Microsoft Edge

The same way Internet Explorer did in
earlier releases, Edge installs together with
Windows 10. However, IE for
communication compatibility is also
included in Windows 10 especially within
the company.
Microsoft Edge

Edge’s features include:
• Inking - an annotation tool that allows
users to write or draw on Web pages.
• Cortana - a personal virtual assistant from
Halo, a popular video game.
• Private browsing.
• Security features such as Microsoft
Passport and asymmetric cryptography to
deter phishing and other social engineering
attacks.
Microsoft Edge

• Support for Firefox and Chrome add-ons.
• Faster overall page rendering.
• Integration with social media.
• Automatic form fill.
• Uncluttered interface.
• Reduced resource consumption to
optimize for low-power devices.
Microsoft Edge

Safari is a Web browser based on the
WebKit engine, created by Apple. A
smartphone edition has been paired with ioS
devices since the iPhone was introduced in
2007, and first published on desktop in 2003
with the Mac OS X Panther. The default
Apple mobile browser is Safari. A version of
Windows from 2007 to 2012 was available.
Apple Safari

Starting with Mac OS but has been ported to
iOS and Windows since then. Safari was
released for the Windows XP SP2 release
for the first time on June 11, 2007. As for the
iOS safari version, it's slightly different from
the OS X version as it uses a different GUI,
Webkit and an API.
Apple Safari

Safari is an OS X Cocoa framework and
uses a rendering WebKit. WebKit itself
consists of the GNU GPL free software,
WebCore and JavaScriptCore, which also
make Safari free. In addition, Apple releases
the code under a 2-clause BSD open-source
permit.
Apple Safari

Opera is the free web browser developed
by Opera Software for Microsoft Windows,
Android, iOS, macOS, and Linux. Opera
uses Blink layout engine as a Chromium
based browser. The user interface and other
features make it distinctive.
Opera

Opera was designed as a research project
at Telenor in 1994 and purchased in 1995
from Opera Software. For the first ten years
it had been a commercial software and had
a proprietary Presto layout engine. The
Opera version of Presto received a number
of prizes, but the production of Presto ended
in 2013 following a significant Chromium
transition.
Opera

Three mobile versions, Opera Mobile,
Opera Touch and Opera Mini, are also
available. On 11 June 2019, a gaming
browser was launched called Opera GX.
Opera

Opera created features which other web
browsers have later adopted, such as:
speed dialing, pop-up blocking, newly
opened shut-off pages, browsing privileging
and tabs. Opera features a bookmarks bar
and a manager for downloads. Opera also
has "Call rates" enabling the user to connect
an infinite number of thumbnail pages to a
page shown during the opening of a new
window. Speed Dial makes navigating to the
selected web pages simpler for your app.
Opera

• Usability and accessibility
• Privacy and security
• Crypto wallet support
• Standards support
Opera

This is where you type the address that you want to visit. If
you had been to a website before, your browser may suggest
it or even automatically complete the address for you. If you
see the address in the collection, you can just click it
Let us define and explain the functions of the
web browser sections:
