Emails
• “E-mail is text-based mail sent via the computer from one person to another.”• “E-mail is an ideal method for sending documents already on your computer using attachments.”•“E-mail is a way to communicate with people as close as your office or as far away as the other side of the world.”
WikiWard Cunningham and co-author Bo Leuf, in their
book The Wiki Way: Quick Collaboration on the Web, described the essence of the Wiki concept as follows:
•A wiki invites all users to edit any page or to create new pages within the wiki Web site, using only a plain-vanilla Web browser without any extra add-ons.•Wiki promotes meaningful topic associations between different pages by making page link creation almost intuitively easy and showing whether an intended target page exists or not.•A wiki is not a carefully crafted site for casual visitors. Instead, it seeks to involve the visitor in an ongoing process of creation and collaboration that constantly changes the Web site landscape.
Social Networking Sites• Social Networking sites offer a way for people
with common interest to interact with one another. They include services such as chats, e-mails, video chats, and instant messaging
• Attempts to make social networking sites began in the early 90s
• Some of the first popular sites were classmates.com (1995) and sixdegrees.com (1997)
• Today, there are hundreds of social networking sites, ranging from dating sites to the friendship based sites, such as Facebook and Myspace
HTML (Hypertext Mark-Up Language)
• HTML is the lingua franca for publishing hypertext on the World Wide Web
• Define tags <html><body> <head>….etc• Allow to embed other scripting languages to manipulate
design layout, text and graphics• Platform independent• Example HTML code:<HTML><head><title>Hello World</title></head>
What are podcasts?•Origin of the term: Pod + Broadcasting= Podcasting•Media files made available on the Web to the public for download to a variety of digital hardware products ranging from personal computers to portable handheld devices (including PDAs, MP3 players, and cell phones) Basic Types of Podcasts•Audio podcasts which consist solely of audio recordings•Enhanced podcasts which are multimedia formats combining audio recordings with images (e.g., a lecture accompanied by a PowerPoint presentation), and•Video podcasts (or vodcasts) which consist of video recordings
Podcasts
What is VoIP?•IP TELPHONY (VOICE over IP)•Transmission of voice telephone calls using internet infrastructure.Why need to IP Telephony?•Economic (uses internet, IP routers...)•Further savings. Because underlying network infrastructure can be shared.•a single set of equipment, wiring, network connection enough.
VoIP
World Wide WebWhat is world wide web? (WWW, Web, w3)•Way of exchanging information.•Network of pages of images, texts and sounds etc.•Platform for user.
STRUCTURE•Clients use browser application to send URIs via HTTP to servers requesting a Web page•Constructed by HTML.•Servers respond with requested Web page or with error message.•Page is written using Hyper Text Markup Language (HTML)•Displaying text, graphics and sound in browser.
StreamingAudio Streaming Concept•Analog-to-Digital modulation•Streaming audio technologies relies on:
Sound sequences Compression schemes
•Compression schemes (encoding) decreases the audio’s bandwidth requirements:
Lowering the audio’s sampling rate Filtering high frequencies Performing other waveform
StreamingAudio Streaming Advantages•Real time audio content.•Low bandwidth media used.•No waiting for downloading audio file.•Internet users can enjoy a live online program. Audio FormatsMicrosoft Windows Media Formats

StreamingVideo Streaming Advantages•Reduce setup time•Reduction in client storage requirement•Video can be viewed in real time •Transmission signals over low bandwidth facilities Video Capture•Converting analog to video signals•A special video capture card to convert the analog signals to digital form and compresses the data.•Also digital video devices that can capture images and transfer to a computerVideo Input FormatsMPEGQuickTimeRealVideo Video for WindowsAVI
Blog• Blogs are found on the Internet.• The term “blog” is short for web log. • A blog is a series of entries, or posts created by someone, stored in
chronological order, are searchable, and allows readers to comment on your content.
• The first “blogger” was a man named Dave Winer and his blog Scripting News has been in existence since 1994; you can find it at www.scripting.com.
Why Blog?• To share information
Personal – blog as a journalProfessional – blog as a product
• As part of their workJournalists – blogs as news outletsBusinesses – blogs as advertising
URL (Uniform Resource Locator)URL Defined•A Uniform Resource Locator (URL) is a standard way developed to specify the location of a resource available electronically.
What are URLs? URLs make it possible to direct both people and software applications to a variety of information, available from a number of different Internet protocols. A URL is like your complete mailing address: it specifies all the information necessary for someone to address an envelope to you.
In short, a URL is a very convenient and succinct way to direct people to a file or other electronic resource. Learning how to interpret, use and construct URLs will assist your exploration of the Internet.
HTTP (Hyper Text Transfer Protocol)
http://<host>:<port>/<path>?<searchpart>
•the host is the Internet address of the WWW server•the port is the port number to connect to(generally omitted along with the colon :) (defaults to standard "80")•path tells the server which file you want (if file name is omitted you want the "home page")•the searchpart may be used to pass information to the server (often to a CGI script)(generally omitted, along with the question mark ?)
Web Feed RSS is an acronymn for Really Simple Syndication or Rich Site
Summary. RSS (noun) - an XML format for distributing news
headlines on the Web.
What is RSS?• RSS is a defined standard for syndicating headlines and other
content. • RSS is created using XML or eXtensible Markup Language, which
is a markup language • Similar to HTML. All fields are defined. Tags are used to denote
the field’s classification. • Like HTML, proper construction requires that tags are both
opened and closed. Example: <title> Title of Item in Feed </title>
Online Chat
• Online chat may refer to any kind of communication over the Internet that offers a real-time transmission of text messages from sender to receiver. Chat messages are generally short in order to enable other participants to respond quickly.
• Online chat may address point-to-point communications as well as multicast communications from one sender to many receivers and voice and video chat, or may be a feature of a web conferencing service.
• Online chat in a less stringent definition may be primarily any direct text-based or video-based (webcams), one-on-one chat or one-to-many group chat (formally also known as synchronous conferencing), using tools such as instant messengers, Internet Relay Chat (IRC), talkers and possibly MUDs.
Social Bookmarking• A social bookmarking service is a centralized online service
which enables users to add, annotate, edit, and share bookmarks of web documents.
• Many online bookmark management services have launched since 1996; Delicious, founded in 2003, popularized the terms "social bookmarking" and "tagging".
• Tagging is a significant feature of social bookmarking systems, enabling users to organize their bookmarks in flexible ways and develop shared vocabularies known as folksonomies.
