  3. 3. Internet The Internet is a global system of interconnected computer networks. http://www.youtube.com/watch?v=iDbyYGrswtg The World Wide Web (abbreviated as WWW or W3, commonly known as the Web or the "Information Superhighway"), is a system of interlinked hypertext documents accessed via the Internet. The origins of the Internet reach back to research of the 1960s. United States government build robust, fault-tolerant, and distributed computer networks. The commercialization of what was by the 1990s an international network resulted in its popularization and incorporation into virtually every aspect of modern human life. As of 2011, more than 2.2 billion people – nearly a third of Earth's population — use the services of the Internet.

  6. 6. Looking for more information? Chris Harrison www.chrisharrison.net/index. php/Visualizations/InternetMap/ The Dimes Project www.netdimes.org What does the Internet look like? How does it evolve? DIMES is a distributed scientific research project, aimed to study the structure and topology of the Internet, with the help of a volunteer community (similar in spirit to projects such as SETI@Home).
  7. 7. Servers and data centers (DC) Server In most common use, server is a physical computer dedicated to running one or more such services (as a host),to serve the needs of users of the other computers on the network. Special program designed to provide service. (email server, FTP server, web server) If regular computer can be a server? Data Center A data center or computer centre (also datacenter) is a facility used to house computer systems and associated components, such as telecommunications and storage systems.
  8. 8. IP address, domain name, hosting IP address An Internet Protocol address (IP address) is a numerical label assigned to each device (e.g., computer, printer) participating in a computer network that uses the Internet Protocol for communication. In IPv4 an address consists of 32 bits which limits the address space to 4 294 967 296. example: 203.45.29.198 A domain name is an identification string that defines a realm of administrative autonomy, authority, or control on the Internet. Domain names are formed by the rules and procedures of the Domain Name System (DNS). imagination.com, google.com, ebay.com.au where is www. ? hosting A web hosting service is a type of Internet hosting service that allows individuals and organizations to make their website accessible via the World Wide Web. domain name

  10. 10. HTML HyperText Markup Language (HTML) is the main markup language for displaying web pages and other information that can be displayed in a web browser. In 1980, physicist Tim Berners-Lee, who was a contractor at CERN, proposed and prototyped ENQUIRE, a system for CERN researchers to use and share documents. In 1989, Berners-Lee wrote a memo proposing an Internet-based hypertext system. Berners-Lee specified HTML and wrote the browser and server software in the last part of 1990. First specifications The first publicly available description of HTML was a document called "HTML Tags", first mentioned on the Internet by Berners-Lee in late 1991. It describes 18 elements comprising the initial, relatively simple design of HTML. Eleven of these elements still exist in HTML 4.
  11. 11. Real example
  12. 12. CSS - Cascading Style Sheets CSS is a style sheet language used for describing the presentation semantics (the look and formatting) of a document written in a markup language. CSS is designed primarily to enable the separation of document content (written in HTML or a similar markup language) from document presentation, including elements such as the layout, colors, and fonts
  13. 13. JavaScript JavaScript (sometimes abbreviated JS) is a scripting language. JavaScript was formalized in the ECMAScript language standard and is primarily used in the form of client-side JavaScript, implemented as part of a Web browser in order to give enhanced user interfaces and dynamic websites. This enables programmatic access to computational objects within a host environment.
  14. 14. web browsers The first web browser was invented in 1990 by Sir Tim Berners-Lee. In 1993, browser software was further innovated by Marc Andreessen with the release of Mosaic (later Netscape), "the world's first popular browser" why bother?
  15. 15. Browser market share April 2012
  16. 16. Protocols HTTP The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems. HTTP is the foundation of data communication for the World Wide Web. HTTPS Same as above but encrypted FTP File Transfer Protocol (FTP) is a standard network protocol used to transfer files from one host to another host over a TCP-based network, such as the Internet.
  17. 17. Email POP3 Post Office Protocol (POP) is an application-layer Internet standard protocol used by local e-mail clients to retrieve e-mail from a remote server over a TCP/IP connection SMTP Simple Mail Transfer Protocol (SMTP) is an Internet standard for electronic mail (e-mail) transmission across Internet Protocol (IP) network IMAP The Internet Message Access Protocol is an Application Layer Internet protocol that allows an e-mail client to access e-mail on a remote mail server. Electronic mail, also known as email or e- mail, is a method of exchanging digital messages from an author to one or more recipients. In 1971 the first ARPANET email was sent
  18. 18. Why we shouldn't send big files via email? Email standards such as MIME don't specify any file size limits, but in practice email users will find that they can't send very large files. As an example, when Google's gmail service increased its arbitrary limit to 25MB it warned that: "you may not be able to send larger attachments to contacts who use other email services with smaller attachment limits". In general, 10MB is considered safe for the maximum size of an email, But why ? base64 The particular choice of character set selected for the 64 characters required for the base varies between implementations. Each attachments grows +30% from it original size
  19. 19. CLOUD Cloud computing is the delivery of computing and storage capacity as a service to a community of end-recipients. The name comes from the use of a cloud-shaped symbol as an abstraction for the complex infrastructure. Cloud computing entrusts services with a user's data, software and computation over a network. cloud storage, cloud music, cloud...
  20. 20. So... what actually Cloud is about? It's just the way how data and services are stored. No limitations, pay for what you use. Easy marketing tool. Dropbox, iCloud, Gmail, Google Drive, Amazon AWS
