Web Hosting - Domain Name Changes and How They Affect You New domain names are registered all the time, and ones previously registered expired. Sometimes that's the result of simple neglect. The owner of the name chose not to renew his or her ownership, so the name became available for someone else to use. In rare cases, a highly original mind managed to think of a new one. In the other common scenarios, someone chose to just let it go or sell it. When you choose to change your domain name, there are actually two separate steps involved: releasing the old name, and adopting the new one. But, just as the postal system can have difficulty forwarding your letters when you change your personal name, changing your domain name brings certain difficulties. One of the most prominent is the fact that any name change requires a change to thousands of DNS Servers around the globe. DNS (Domain Name System) is the set of software/hardware components that allows domain names to map to IP addresses. IP addresses are what are actually used 'under the covers' when one computer communicates with another. Note that there isn't always a 1:1 correspondence between a name and an IP address. One IP address can serve multiple domain names and one domain name can have multiple IP addresses. For the sake of simplicity, we'll stick to the common case here. DNS servers around the world maintain internal databases that match the name to an IP address. Not all servers have all pairs of names/addresses. A series of complex routines allows a request to be forwarded when the particular DNS server doesn't have a needed record. When you acquire a domain name that used to be associated with a given IP address, the odds of you acquiring the same IP address are extremely low. In the unlikely case, for example, that you acquired the domain name yahoo.com, you would almost certainly not get the IP address that was matched with it (unless you bought the Yahoo! company). So, as a result of the change, the name/IP address pair is no longer what it was. A similar circumstance exists when you retain your IP address, but want to change the domain name associated with it. In either case, the pairing has changed. The catch is this: when the change takes place, those DNS databases are not all updated instantaneously around the world. Even apart from the limited speed with which computers and networks operate, (and neglecting the human factor if/when the change is made manually to more than one server) the reason is something called caching. In order to communicate efficiently, DNS servers are designed to assume that changes will be relatively rare. Just as with the postal system, you don't move your address or change your name every minute. Since that's true, in general, the name/IP address pair is cached. A cache is a set of stored information that is reused so that fresh information doesn't have to be communicated with every request for a web page or data. A chain of DNS servers pass requests to the last known address. There is usually more than one system between your computer and the server you want to communicate with. Most of the time, that's your current name/address. When you change the name, that pair is no longer valid. In order to propagate the new name/address pair (so the terminology goes), that cache has to be refreshed. Something similar happens when you establish an entirely new name. That name is first associated with an IP address and that pair has to be communicated to DNS servers around the world in order for you to be able to reach any one of them at random. But DNS servers don't do that until they are requested to do so by your action of asking for information from a remote server. Because of that, but chiefly because of caching, it can take quite a while for the new pair to become known around the Internet. Caches can expire and get refreshed in a few minutes or a few hours. It varies. That time can be as short as an hour or less, if the path between your computer and the web server is very simple and only one DNS server needs to be updated. Or, it can take up to 48 hours or more. Though the 'official' range is often given by registrars as 24-48 hours, the average is closer to about six hours. But that's an average. The actual time in any given case can (and does) vary widely. In the meantime, a number of effects can occur. The most obvious is that, since the name/IP address pair can't be resolved properly, you don't reach the server you want. Your browser points to the old one (in the rare case it's still accessible by that name and address), or it simply reports there's no such name at that address. So, when registering a new name or buying an old one, you should establish the site, but not advertise it for at least a couple of days. Better to wait to get visitors than to turn them off by being 'not at home' when they call.

Software copyright act The Software Copyright Act was a Great Step in the Right Direction The software copyright act, which is actually called the Digital Millennium Copyright Act has given software developers a little more power when it comes to protecting their works. If you've bought software in the last few years I'm sure you've noticed some of the changes that have been made in the software buying process. If not, then you really should wake up and take note. Some of the more noteworthy achievements of this act are the following: 1) It is now a crime to go around anti-piracy measures in software. 2) It is no longer legal to make, sale, or give away software or devices that were invented for the purpose of cracking codes enabling the illegal copying of software. 3) Limits the liability that ISPs (as far as copyright infringement violations) when information is transmitted online. The problem isn't the people want to be bad or do something wrong. Most of us by nature want to do the right thing. The problem lies in educating people to the fact that it really is stealing when you bootleg, pirate, illegally download, or otherwise acquire copies of software that you didn't pay for. It's one of those 'white lie' types of crimes for most people and they don't really see how it will hurt anyone for them to copy a game that their brother, cousin, uncle, or friend has. Someone paid for it after all. The problem is that at $50 plus being the average price for computer games and simple software if 10 million people are doing it, the numbers are staggering and they add up quickly. The software copyright act sought to protect businesses from losing money this way. The software copyright act was the worldwide response to a growing problem. This problem was so widespread with illegal downloading of music that lawsuits and massive commercial ad campaigns were initiated in order to curtail illegal downloading activities when it comes to music. It seems to be working to some degree. Fewer people are illegally downloading music; the downside is that these people aren't buying as much music either. The reason is because they are no longer being exposed to the wide variety of music and artists that they were getting freely when downloading music each night at no cost. This equals lower record sales and is becoming a problem of lower movie sales and software sales as well. People aren't trying new games like they could before the software copyright act by going to LAN parties and everyone sharing a copy to play, now everyone has to own a copy before they can play. While this may be great for the companies that make a few (a minimal few at best) extra sales on the games for the sake of a great party but for the most part, it is costing them the extra money that could be made by 10 people finding they liked the game enough to go out and buy it so they could play it whenever (and the next group of 10 they will introduce the game to) Gamers are a funny group and software copyright act or no, they are going to stick with the software and games that serve them best. The software copyright act was created in order to protect the rights of those writing and developing computer software. We want those who fill our lives with fun games, useful tools, and great ways to connect to friends and family to continue providing these great services and to get paid for the ones they've already provided. The software copyright act is one giant step in the right direction as far as I'm concerned.

Check Download.com for the Best Free Security Software Around With viruses, spyware, adware and hackers threatening on every corner of the internet, it is essential that especially internet users protect their PCs as best as they can to not loose their files or even their whole PC.

Just by checking what for example download.com has available, computer users might be able to save as much as 50-100 Dollars and still be able to protect their PCs adequately. One part of the web page called antivirus, firewall and spyware offers different links to downloads from companies that help protect PCs from any harm. Most of the programs offered on the web page are free for download. Some of the programs are antivirus software, which generally will scan the PC according to your settings for example once a day. When the software finds a virus in any of the files on the PC it will put out a virus alarm in form of a message box. The PC users then have to decide in which way the PC should be cleaned. Some antivirus software will offer to delete the file, others save it in what is called a virus vault, where the virus cannot attack other files on the PC, while others clean the file if it is cleanable.

Firewalls protect the Pc from any attacks form the internet, such as hackers hacking into your PC, Trojan horses, viruses and more entering the PC is not possible, when a firewall is used and set to the proper security setting. Using a firewall is a good idea for any PC, but it is important to know that the way the firewall works it might also cause a few problems with software on the Pc that enters the Internet. Therefore firewalls need to be configured right to have a smooth running and protected PC. Many of the firewalls offered on this page are free for download, but generally most PCs have a built in firewall in their operating system that just needs to be activated or configured. The third major kind of protection software one can download form this website is spy or ad-aware detection. Spy and ad-aware are programs that are malicious for the PC user. These kind of malicious little programs are installed without the users proper knowledge and intercept or partially take control of the interactions of the PC with the internet without the users consent. Spywares do not just monitor the internet interactions, as the name suggests, it also collects personal information, can install additional software that will take over the control of the browser activity, accessing websites that will allow for example viruses to enter the PC. Spyware is also often called privacy-invasive software and something a PC as well as a user needs to be protected from. The download page does not only offer many of these programs for free, it will also offer patches and update files for these programs. Even though many of the companies offer the continuous automatic update to protect a PC from new viruses and other malware, some PC users prefer not to have an automatic update and download their own updates whenever they deem necessary. Whichever way one likes to update the PC, it is most important of all to know that PCs need to be protected and users do not need to spend tons of money in order to do so. Free programs available for download on download.com will give a PC similar protection and keep files and identity safe.
