2. Understanding Web browsing: Consult a page / website = - Open a file from a remote computer (in general), since a given address (URL) or a hyperlink. - To display it on its own computer with appropriate software to interpret the source (the browser). 3. The browsers, software Web The Web browser is a software designed for the World Wide Web.
Web servers are important in today’s internet market, they implement the Hyper Transfer Protocol (HTTP) and it can be run by any computer. It could be used in a local network as well on a wide diversity web site around the globe, enabling user to read information from various resources. A web server enables users to move from one site to another by links call Hypertext Markup Language (HTML). This hyperlinks are the responsible of setting fonts, emending related files (e.g. graphics), and setting fonts in web pages.
Not only you can use for communication, but also you can share pictures and videos through Internet. In addition, Internet follows a client server architecture. In a computer, there is a client or software program that requests informations form a server. Server provides requested information to clients. A computer can have several types of server software.
The World Wide Web (WWW) is mostly used on the Internet. The Web refers to a body of information, while the Internet refers to the physical side of the global network containing a large amount of cables and computers. The Internet is a 'packet-switching' computer network. When a person sends a message over the Internet, it is broken into tiny pieces, called 'packets'. These packets travel over many different routes between the computer that it is being sent from to the computer to which it is being sent to.

UNIT 33 – P1-P2-P3-P4-P5-P6 Introduction: In this assignment I will be describing how the internet operates. Example of internet server: How the internet works? The internet and the worldwide web The World Wide Web and the internet is not the same thing, and they are often confused with being the one and same. However, the internet existed long before the www (World Wide Web). The internet refers to the massive network of computers stretching all over the world.
Internet Regulation What is the Internet? The definition of the Internet put in one sentence is: A worldwide network of computer networks that use the TCP/IP network protocols to facilitate data transmission and exchange, where anyone with a computer can access the internet through an ISP (Internet Service Provider). The Internet consists of a three level hierarchy composed of backbone networks (e.g. ARPAnet, NSFNet, MILNET), mid-level networks, and stub networks. These include commercial (.com or .co), university (.ac or .edu) and other research networks (.org, .net) and military (.mil) networks and span many different physical networks around the world with various protocols, chiefly the Internet Protocol.
Type netstat -r at the command prompt to see the ip of all computers you are connected to In MSN (and other programs) when you are chatting to someone everything you type goes through the MSN servers first (they act as a proxy) so you see their ip rather than who you are chatting to. You can get round this by sending them a file as MSN doesn't send file through its proxy. When you type the netstat -r (or -a for a different view) the ip's are under the foreign address table. The ports are separated by a : . Different programs use different ports, so you can work out which ip's are from which program.
• Describe the use of digital signatures to verify identity on the internet. • Explain the purpose and potential risk associated with cookies. Internet Internet is computers network connected around the World via dedicated servers. When your computer is connected to the internet you can send, received all kinds of information such as text, graphics, voice, programs and video. The Internet history began with development of the computers.
For example, your Internet server provider may provide you with a PPP connection so that the provider's server can respond to your requests, pass them on to the Internet, and forward your requested Internet responses back to you. PPP uses the Internet protocol and is designed to handle others. It is sometimes considered a member of the TCP/IP suite of protocols. Relative to the OSI reference model, PPP provides layer 2 (data-link layer) service. Essentially, it packages your computer's TCP/IP packets and forwards them to the server where they can actually be put on the Internet.
