The World Wide Web (commonly shortened to the Web) is a system of interlinked hypertext documents accessed via the Internet. With a Web browser, a user views Web pages that may contain text, images, videos, and other multimedia and navigates between them using hyperlinks. The World Wide Web was created in 1989 by Sir Tim Berners-Lee, working at the European Organization for Nuclear Research (CERN) in Geneva, Switzerland and released in 1992. Since then, Berners-Lee has played an active role in guiding the development of Web standards (such as the markup languages in which Web pages are composed), and in recent years has advocated his vision of a Semantic Web.
Viewing a Web page on the World Wide Web normally begins either by typing the URL of the page into a Web browser, or by following a hyperlink to that page or resource. The Web browser then initiates a series of communication messages, behind the scenes, in order to fetch and display it.
First, the server-name portion of the URL is resolved into an IP address using the global, distributed Internet database known as the domain name system, or DNS. This IP address is necessary to contact and send data packets to the Web server.
The browser then requests the resource by sending an HTTP request to the Web server at that particular address. In the case of a typical Web page, the HTML text of the page is requested first and parsed immediately by the Web browser, which will then make additional requests for images and any other files that form a part of the page. Statistics measuring a website's popularity are usually based on the number of 'page views' or associated server 'hits', or file requests, which take place.
Having received the required files from the Web server, the browser then renders the page onto the screen as specified by its HTML, CSS, and other Web languages. Any images and other resources are incorporated to produce the on-screen Web page that the user sees.
Most Web pages will themselves contain hyperlinks to other related pages and perhaps to downloads, source documents, definitions and other Web resources. Such a collection of useful, related resources, interconnected via hypertext links, is what was dubbed a "web" of information. Making it available on the Internet created what Tim Berners-Lee first called the WorldWideWeb (a term written in CamelCase, subsequently discarded) in 1990. | |

 | Belkin N1 Wireless Modem Router | Belkin’s installation routine veers from the norm so don’t try and plug it in and access it immediately with a web browser as you won’t get anywhere. You need to run the CD-ROM based setup utility first which will search for the router and request your ISP details, set up the wireless access point and reboot the unit ready for use. This process changes the router’s default IP address to the one listed in the manual and sets up the DHCP server to provide addresses in the same range. The setup routine only take few minutes to run after which you can then access the web browser management interface.
It soon becomes apparent that despite the above average price the router is a little short on features. You get the standard NAT/SPI firewall, which you can enable or disable for whatever reason and create up to twenty virtual server entries for routing certain inbound traffic to specific systems identified by their IP address. A single system can be placed in a DMZ where it circumvents the firewall and you can stop the WAN port responding to Pings from the Internet. The client IP filter feature could be useful as it enables you to designate ranges of IP addresses on the LAN and restrict access to the Internet or particular services permanently or to a basic schedule. | |

 | Hack | Knock Knock - Who is hacking out there?
Ever since I got DSL a couple of years ago, I've had a firewall installed on my PC. Didn't have to worry about such things in the dial-up era, of course — but with a static IP address, the experts assure me that I'm more vulnerable to hackers trying to get into my computer.
And in perusing through the logs my firewall software maintains, I see that the experts are right- there are dozens of attempts a day to log/hack into my computer.
What the logs can't answer is why — as in, why try to hack into my computer.
Of course, since until recently I used Win98, there wasn't really much hackers could do. There is no Unix-like log-in feature on Win98 — so if you have file sharing turned off, about all they could do was ping my machine to see if it was on.
Of late, I've added a Mac and a couple of old Pentiums with Linux to the home network. The Mac is running OS9, so it's as difficult to get into as the Win98 box — security through obsolescence, that's my motto. (And just let them try hacking into the Apple][!)
The Linux boxes do have advanced login features, of course — but they also have really secure firewalls, so I don't worry too much about them. (Which isn't to say I don't back up my files religiously just in case ...)
Still, it's mostly a Windows world we live in, and as I'm in the midst of upgrading to WindowsXP, this whole DSL/static I.P. situation is a bit worrisome. XP is the closest Windows has yet come to approximating a real operating system — meaning that it includes various Internet tools like ftp host, telnet host, real Web server, all in true multi-user environment.
Further meaning that it's going to be a lot easier to get into than the obsolete but secure Win98.
But if we accept the fact that there will be hackers trying to get into my home computers, can we try to figure out who they are?The firewall log contains a line of information for each "event" that shows the date and time of the attempted connection, as well as the IP address of the originating computer.
By going to the American Registry for Internet Numbers and entering an IP number in the Whois search box at the top of the home page, you can find out who that number is assigned to.
But — and this is a big but — in most cases, that won't tell you which individual actually has that IP address assigned to their computer. For instance, when I type in one of my own static IP numbers, the ARIN Whois returns the contact info for my Internet service provider — the true holder of that number.
I could, I suppose, contact the ISP and report that their customers were trying to get into my computer — but what good would that do? ISPs are in business to make money, and accusing their customers of hacking is likely to run counter to that larger goal of profitability.
I can — and have — tried logging back into these dozens of IP addresses in my firewall log. Of course, these folks who are snooping around trying to get into my computer have very tight security on their own PCs; I haven't gotten so much as a login prompt on a single one. It only stands to figure that a burglar will have the best locks at home.
As to what they're hoping to find on my PC, I can't even guess. If it's porn, they'll be sorely disappointed. MP3s? Sorry, most of my music is still on vinyl. For the most part, what I have on this system is working copies of my Web pages — the same stuff you can find by going to my site.
It is, frankly, weird imagining folks sitting in front of their computer hour after hour, typing in IP addresses one after the other, trying to find an open system. The act itself is odd enough; the motivation is frankly beyond me.
But should one of these hackers ever actually get in, no doubt they'll erase the firewall log anyway — meaning even then I won't get to ask them just what it is they're looking for.
