Transcript of Internet

Web 2.0 The Web 2.0 provides more services to the ones already existing on the internet.

It allows users to interact and collaborate with each other in a social media as creators of user-generated content in a virtual community, in contrast to websites where people are limited to the passive viewing of content. How it works?
The Internet is a global system of interconnected computer networks. It is a network of networks. What is it? The Internet Services of the Internet The World Wide Web and Web 2.0 are the key services of the Internet that allow us to interact with it in many different ways, such as wikis, blogs, video and photo uploading, etc. How does it work? What is it? What services does it provide? World Wide Web The internet is not managed or controlled by anyone in particular. This is the key of its many advantages but also of its disadvantages. The Internet It's a system of interlinked hypertext documents accessed via the Internet. With a web browser, one can view web pages that may contain text, images, videos, and other multimedia, and navigate between them via hyperlinks. Wikis Rss Blogs Video & image hosting Voice over IP Services Web mapping And much more! Thank you for watching Wikis A wiki is a website which allows its users to add, modify, or delete its content via a web browser usually using a simplified markup language or a rich-text editor.Wikis are powered by wiki software. Most are created collaboratively.

Wikis serve many different purposes, such as knowledge management and notetaking.

Some permit control over different functions (levels of access). For example, editing rights, access control and organizing content.

A very well know example of a wiki is Wikipedia. Video & image hosting A video or photo hosting service allows individuals to upload video clips or images to an Internet website.

Typically image hosting websites provide an upload interface in which you specify the location of an image file on your local computer file system (using a browse button). After pressing a “Submit” button the file is uploaded to the image host’s server.

An example of a video sharing website is YouTube, where users can freely view videos, and register freely to upload videos.

An example of an image and video hosting site is Flickr. Photos and videos can be accessed without registering, but doing so allows one to upload videos and images. RSS services RSS (Rich Site Summary) is a family of web feed formats used to publish frequently updated works.

A web feed (or news feed) is a data format used for providing users with frequently updated content such as such as blog entries, news headlines, audio, and video.

In the case of video and audio content, it's called Podcast. Voice over IP Voice over IP commonly refers to the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

A common example is Skype. Skype allows users to communicate by voice using a microphone, video by using a webcam, and instant messaging over the Internet.

Calls to other users within the Skype service are free of charge, while calls to landline telephones and mobile phones are charged. Skype can also be used to transfer files. Blogs A blog is a discussion or informational site published on the World Wide Web and consisting of discrete entries ("posts") typically displayed in reverse chronological order (the most recent post appears first).

Most good quality blogs are interactive, allowing visitors to leave comments and even message each other.

Blogs may be used for commentary on a particular subject, personal online diaries, or online brand advertising. A typical blog combines text, images, and links to other blogs, Web pages, and other media related to its topic.

An example of a blogging site is Blogger. Web mapping Web mapping is the process of designing, implementing, generating and delivering maps on the World Wide Web.

A special case of web maps are mobile maps, displayed on mobile computing devices, such as mobile phones, smart phones, PDAs and GPS.

Examples include Google Maps. It offers street maps, a route planner for traveling by foot, car, bike, or public transport and an urban business locator for numerous countries around the world. By: Sergio Rojas Social networking Social networking A social networking service is an online service, platform, or site that focuses on facilitating the building of social networks or social relations among people who, for example, share interests, activities, backgrounds, or real-life connections. A social network service consists of a representation of each user (often a profile), his/her social links, and a variety of additional services. Most social network services are web-based and provide means for users to interact over the Internet, such as e-mail and instant messaging. Online community services are sometimes considered as a social network service, though in a broader sense, social network service usually means an individual-centered service whereas online community services are group-centered. Social networking sites allow users to share ideas, activities, events, and interests within their individual networks. It's an online service, platform, or site that focuses on facilitating the building of social networks or social relations among people who share interests, activities, backgrounds, or real-life connections.

They are web-based and allow users to interact over the Internet, such as e-mail and instant messaging.

Facebook has over one billion active users more than half of them using Facebook on a mobile device.
Users must register before using the site, after which they may create a personal profile, add other users as friends, and exchange messages, including automatic notifications when they update their profile. Additionally, users may join common-interest user groups.
