Browsers are applications that allow users to access and view web pages on the internet. Common browsers include Internet Explorer, Firefox, and Chrome. Search engines are software programs that search the web for information and return relevant results on search engine results pages (SERPs). Popular search engines are Google, Bing, Yahoo, and DuckDuckGo. Search engines are categorized as crawler-based if they use automated software to index web pages, human-powered directories if they rely on human editors to categorize sites, or hybrid models that incorporate both approaches. Browsers display web pages while search engines help users find information on the internet.

2. Browsers
• A web Browser is an application to
connect computers with Internet
• It helps in accessing and displaying
web pages.
• Commonly used Web Browsers are
Internet Explorer, Netscape
Navigator, Firefox, Google Chrome
etc.

3. Search Engines
• A web Search Engine is a software
system that is designed to search for
information on the World Wide Web.
• The search results are generally
presented in a line of results often
referred to as Search Engine Results
Pages (SERPs)
• Commonly used search engines are
Yahoo, Google, MSN Search, Bing,
Ask.com, AOL.com, Baidu, DuckDuckGo
etc...

4. Types of Search Engines
• Crawler-Based Search Engines
• Human-Powered Directories
• Hybrid Search Engines" Or Mixed
Results

5. Crawler-based search engines
• E.g. Google, AllTheWeb and AltaVista
• Create their listings automatically by using a
piece of software to “crawl” or “spider” the
web and then index what it finds to build the
search base.
• Web page changes can be dynamically caught
by crawler-based search engines and will
affect how these web pages get listed in the
search results.

6. • Good for specific search when topic is in
mind.
• If search topic is general, crawler-base search
engines may return hundreds of thousands of
irrelevant responses to simple search
requests.

7. Human-Powered Directories
• Eg. Yahoo directory, Open Directory and
LookSmart
• depend on human editors to create their listings.
• Typically, webmasters submit a short description
to the directory for their websites
• or editors write one for the sites they review
• these manually edited descriptions will form the
search base.
• Therefore, changes made to individual web
pages will have no effect on how these pages get
listed in the search results.

8. • Human-Powered directories are good when
you are interested in a general topic of search.
• In this situation, a directory can guide and
help you narrow your search and get refined
results.
• However, this is not an efficient way to find
information when a specific search topic is in
mind.
