Browser vs. Server
Web Browser
Current market leaders:
1. Google’s Chrome
Preferred by Web Developers
2. Firefox
The legacy of Netscape
3. Apple’s Safari
Leading in mobile browsing
4. Microsoft’s Internet
Explorer
Still around
Web Server
Current market leaders:
1. Apache
http://httpd.apache.org/
2. Microsoft’s IIS
Internet Information Services
3. Nginx
http://wiki.nginx.org/
4. GWS
Google’s Web Server
Browser Wars
Early Business Model:
1. Give your web browser to users for free
2. Sell your web server to companies $$$
3. Web pages will work best if your server and
browser are both used.
4. If more people use your browser, more
companies will want to buy your server.
Browser Wars
Rough Timeline:
• In 1995-1998 Netscape dominated early market 90%
• In 2001 Microsoft wiped Netscape out of existence.
92% market share
• In 2008, Firefox was the only browser seriously
challenging Internet Explorer (IE)
• In 2012, IE was finally overtaken by Google Chrome
• Today, Apple’s Safari is the leader in the mobile
browser market. Chrome is not far behind.
Browser Popularity
Browser vs. Server
Web Browser
• Makes http requests
– Asks for web pages
• Renders web pages
– Converts HTML, CSS and
JavaScript into displayed
document.
• Remembers browsing
history, preferences and
cookies
Web Server
• Responds to http requests
– Sends web pages
• Processes requests
– Create dynamic pages
– Run web applications
– Fetch data from Databases
– Store session data
Development: Backend vs. Frontend
Frontend:
What you see on the Web
Browser
• Graphic design
• Image production
• Interface design
• User experience
• HTML markup
• CSS styles
• Sometimes JavaScript
Backend:
What happens on the
Web Server
• Processing Data
• Database Programming
• Content Management
Systems
• Server-side Scripting
– PHP, ASP, Ruby, JSP
• Sometimes JavaScript
Multimedia
Unlike other documents, web pages have many layers capable of combining
almost any form of media
• Text & Images
– obviously
• Audio
– Embedded players and files
(mp3)
• Video
– Embedded players and fiels
(mp4)
• Animation
– Flash-driven, JavaScript,
jQuery, and CSS-based
• Interaction
– Embedded Programs &
Application
– “interaction” is a form of
media. Very different than
passively viewed video.
Internet vs. WWW
Internet
• Physical Hardware Layer
– WiFi Routers
– Ethernet Switches
– Cable Modems
• Key Technologies
1. TCP/IP Protocol
2. Packet Switching
World Wide Web
• Widely-available Content
Layer of Internet
– Web servers
– Email
– File sharing (FTP)
• Key Technologies
1. HTTP Protocol
2. URLs
Key Internet Concepts
• TCP/IP:
Transmission Control /
Internet Protocol
– Network of Networks
concept
• Packet Switching:
Data is broken into small
packets that can be
independently routed
• Think of the Internet as
earth’s network of
highways and ports (sea
and air)
• TCP/IP establishes
standards for roads and
ports so people can get
everywhere seamlessly.
• Packet Switching means
cargo can travel in small
chunks to easily move
through bottlenecks via
different paths.
Key WWW Concepts
• HTTP:
Hypertext Transfer Protocol
– Rules for making requests and
responding to requests.
• URI:
Uniform Resource Identifier
– Unique identifier for finding
stuff on the WWW; Includes:
URL (Location) and
URN (Unique Name at
Location)
• Think of the WWW as
everything that can be
publicly accessed from the
world’s highways, airport
and sea ports.
• Think of HTTP as the
standard language used to
ask for directions.
• Think of URLs as street
addresses and URNs as IDs
for objects at particular
addresses.
Internet is bigger than WWW
• The Internet’s protocol (TCP/IP) can support
many sub-protocols, some that are proprietary
(private/secret).
• Examples:
– Many peer-to-peer files sharing systems
– Specialized client-server systems (early banking
systems)
– Content so deeply embedded in systems that its very
hard to find (Deep Web)
– Content requiring access via secret non-standard
browsers (Darknet)
But, the WWW matters more
• The HTTP protocol standardizes requests so
any web browser can access any web server.
• URLs (WWW layer) makes finding and
remember servers much easier than numeric
IP addresses (Internet layer)
• The WWW is all about accessibility via open,
widely adopted standards.
– It’s the largest, most expandable information
system ever built.
URLs
• Let’s look at real examples…
