Web browser as a computer program used for accessing
sites or information on a network (as the World Wide
Web). This is a simple, yet accurate description. Web
browsers come in many different styles, each with their
own nuances. However, the main reason a person utilizes a
browser is to view Web pages on the Internet, similar to the
way you are viewing this article right now.

The browser application retrieves or fetches code, usually written
in HTML and/or another language, from a webserver, interprets
this code, and renders it as a Web page for you to view. In the
majority of cases, user interaction is needed to tell the browser
what website or specific Web page he or she would like to view.
One way this is done is via the browser's address bar.
The web address, or URL, that you type into the address bar tells
the browser where to obtain a page or pages

Web browsers like Internet Explorer,
Firefox, Chrome, and Safari rank among the
most popular network applications in the
world. People use them for basic
information browsing but also for various
other needs including online shopping and
casual gaming. Web servers supply content
to Web browsers via Internet network
connections.

In addition to most browser makers focusing on the everyday user looking to
surf the Web, they also cater to the Web developers, designers and quality
assurance professionals who help build the apps and sites that those users are
accessing by integrating powerful tools right into the browsers themselves.
The tutorials below walk you through how to access these developer tools in
several popular Web browsers:
 Google Chrome
 Mozilla Firefox
 Microsoft Edge / Internet Explorer
 Apple Safari

Chrome's developer tools allow you to edit and debug code, audit individual
components to expose performance issues, simulate different device screens
including those running Android or iOS, and perform several other useful
functions :
 Click on Chrome's main menu button, marked with three horizontal lines and
located in the upper right-hand corner of the browser.
 When the drop-down menu appears, hover your mouse cursor over the More
tools option
 A sub-menu should now appear. Select the option labeled Developer tools

 The Chrome Developer Tools interface should now be displayed.
 In addition to these sections you can also access the following tools via
the >> icon, located to the right of the Timeline tab.
 Device Mode allows you to view the active page in a simulator which renders it
almost exactly as it would appear on one of over a dozen devices, including
several well-known Android and iOS models such as the iPad, iPhone and
Samsung Galaxy.
 You can also customize the look and feel of your developer tools by first
clicking on the menu button represented by three vertically-placed dots and
located on the far right-hand side of the aforementioned tabs.

Firefox's Web Developer section includes tools for designers, developers and
testers alike such as a style editor and pixel-targeting eyedropper.
 Click on Firefox's main menu button, represented by three
horizontal lines and located in the upper right-hand corner of the
browser window.

When the drop-down menu appears, select the icon
labeled Developer. The Web Developer menu should now
be displayed, containing the following options. You'll
notice that most menu items have keyboard shortcuts
associated with them.
 Toggle Tools
 Inspector
 Web Console
 Debugger
 Style Editor
 Performance
 Network
 Developer Toolbar
 WebIDE
 Browser Console
 Responsive Design View
 Eyedropper
 Page Source

Commonly referred to as the F12 Developer Tools, an homage to the keyboard
shortcut that has launched the interface since earlier versions of Internet
Explorer, the dev toolset in IE11 and Microsoft Edge has come a long way since
its inception by offering a very handy group of monitors, debuggers, emulators,
and on-the-fly compilers.
 Click on the More actions menu, represented by three dots and located
in the upper right-hand corner of the browser window.
 The development interface should now be displayed, typically at the
bottom of the browser window.

To display the Console while within any of the other tools click
on the square button with a right bracket inside of it, located in
the upper right-hand corner of the development tools interface.
To undock the developer tools interface so it becomes a
separate window, click on the button represented by two
cascading rectangles or use the following keyboard
shortcut: CTRL+P.

Safari's diverse dev toolset reflects the large developer community that
utilizes a Mac for their design and programming needs. In addition to a
powerful console and traditional logging and debugging features, an easy-
to-use responsive design mode and a tool to create your own browser
extensions are also provided.

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 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.

Search engine algorithms take the key elements of a web page,
including the page title, content and keyword density, and come up
with a ranking for where to place the results on the pages. Each
search engine’s algorithm is unique, so a top ranking on Yahoo!
does not guarantee a prominent ranking on Google, and vice versa.
To make things more complicated, the algorithms used by search
engines are not only closely guarded secrets, they are also
constantly undergoing modification and revision. This means that
the criteria to best optimize a site with must be surmised through
observation, as well as trial and error — and not just once, but
continuously.

Search engines are :

What helps Google stand out from its competition and
helps it continue to grow and be the number one search
engine is its Page Rank technique that sorts search
results. While being one of the best search engines on the
Internet, Google also incorporates many of its other
services, such as Google Maps and Google Local, to
provide more relevant search results.

Yahoo! is an Internet portal that incorporates a search engine and a
directory of World Wide Web sites organized in a hierarchy of topic
categories. As a directory, it provides both new and seasoned Web
users the reassurance of a structured view of hundreds of thousands of
Web sites and millions of Web pages. It also provides one of the best
ways to search the Web for a given topic. Since Yahoo is associated
with the most popular Web search sites, if a search argument doesn't
lead to a Yahoo topic page, it will still lead to results from the six or
seven popular search engine sites Yahoo links to.

Bing launched with several features that are unique in the
search market. For example, when you mouse-over a Bing
result a small pop-up provides additional information for
that result, including a contact e-mail address if available.
The main search box features suggestions as you type, and
Bing's travel search is touted as being the best on the net.
Bing is expected to replace Microsoft Live Search.
