This week we are learning the composition of computer network and its development process: from single to C (client) / S (server) architecture to B (browser) / S (server) architecture. Understand the so-called "7x24hours" service (full-time), fat client, fat server and client now learned (client) is also the application (application). Learn how each operator as well as the Ubuntu Linus to see networking situation (use the ping command on Win; available using the ipconfig command on Linus); and learned through the Windows command ipconfig / all also be able to query the computer's network card (interface) state, address the card is unique; and also know how to check the MAC physical address. Also know nslookup composition: domain name + IP. The website address is learned dynamically allocated (DSCP) of. We know the importance of the "agreement". I learned several types of network: LAN, WAN and MAN. Wherein the local area network WLAN configuration management topology is called (with ring topology, star topology). I learned several important elements of Internet connection: Internet backbone network, ISP (Internet Service Provider).

Finally, Chapter XVI of study, I understand the World Wide Web (relatively new software using the network to exchange information and combine) the difference between the Internet and I know how to create a (personal customization) website to learn how to establish a unified address with the site URL; know the big search engines computing workload. A preliminary understanding of the cookie (browsing traces); know how to use HTML to create a simple website to learn the basic HTML formatting, etc.
