slide1. Unit- 5 5.1 Multimedia and Internet<br>
slide2. 5.1.1 . Client –server Technology Two or more computers connected to each other make a network or client and server technology<br>
slide5. 5.1.2 . Communication protocols TCP / IP: is the protocol used for communication on the internet
TCP Transmission Control Protocol
IP Internet Protocol
Http: Hyper text transfer protocol -- > to access websites
https: secured http
In 1983 Domain Name System (DNS) was established to assign names and addresses to computers which were linked to the internet.
Ex: www. yahoo.com
www. google.com
https: www. exim. co .tz<br>
slide6. 5.1.3. Internet Addressing syntax:
Protocol:// domain Name / path/file name
Ex: http: // www.exim.co.tz/home.php
The server directly path and file name are often left off.
The protocol usually does not need to be typed.
The protocol is also often hidden, such as
Mail to
news<br>
slide7. 5.1.3. Internet Addressing top level Domains
.com
.net
.gov
.mil
.edu
.org
Two letter country codes.<br>
slide8. 5.1.4. Internet Function To connect to the Internet, a computer or networks needs
A data connection to a server
the data connection can be wireless or a land line
you usually need account with the server
most people access a server through an internet service provider (ISP)
TCP/IP software
Your operating systems may need to be configured to connect to the server and use TCP/IP software<br>
slide9. 5.1.5 origin of World Wide Web The World-Wide Web began in March 1989 at CERN. (CERN was originally named after its founding body the “Conseil Europeen pour la Recherche Nucleaire,” and is now called “European Laboratory for Particle Physics.”
The hyper text transfer protocol (HTTP) was designed as a means for sharing documents over the internet
The hypertext markup language (HTML) is the markup language of the web.
Cross –platform compatibility was a design goal.<br>
slide10. 5.1.6 HTML and Web Authoring Web authoring is the practice of creating web documents using modern web authoring software and tools.
Web authoring software is a type of desktop publishing tool that allows users to navigate the tricky environment of HTML and web coding by offering a different kind of graphical user interface.<br>
slide11. HTML stands for Hypertext Markup Language, and it is the most widely used language to write Web Pages.
Hypertext refers to the way in which Web pages (HTML documents) are linked together. Thus, the link available on a webpage is called Hypertext.
As its name suggests, HTML is a Markup Language which means you use HTML to simply "mark-up" a text document with tags that tell a Web browser how to structure it to display.
Originally, HTML was developed with the intent of defining the structure of documents like headings, paragraphs, lists, and so forth to facilitate the sharing of scientific information between researchers.
Now, HTML is being widely used to format web pages with the help of different tags available in HTML language. 5.1.1.7. Brief Overview of HTML<br>
slide12. Web browser is a software applications for retrieving, presenting, and traversing information resources on the WWW.
Web browsers are :
Internet explorer
Netscape navigator
Opera
Mozilla firefox
Google chrome 5.1.1.8 . Web Page Browsers<br>
slide13. web browsers have increasingly grown to support plug-in technologies such FLASH and Java
Web Browsers often vary from th HTML standards
Support for features such as cascading style sheets (CSS) 5.1.1.9. Web Page development<br>
slide14. Plug-ins and delivery vehicles
Plug-ins add capabilities to the web browsers
Types of Plug-ins include
Text ( Adobe Acrobat Reader)
Images ( Macromedia Shockwave) which allows the display of vector graphics
Sound : Plug-ins such as Real Player , Quick Time, and Windows media player and play music
Animation, Video, and Presentation
Real Player , Quick Time, and Windows Media Player also play animation and video
Flash and Shockwave are used for animation and presentation
Microsoft power Point can be used for online presentation. 5.1.1.10.Multimedia consideration for Internet<br>
