“Voice over Internet Protocol” or VoIP is technology that lets you make and receive phone calls over the Internet through an online VOIP service. VoIP is often used abstractly to refer to the actual transmission of voice (rather than the protocol implementing it). VoIP is clearly identified as a Least Cost Routing (LCR) voice routing system, which is based on checking the destination of each telephone call as it is made, and then sending the call via the network that will cost the customer the least.

VoIP is widely employed by carriers, especially for international telephone calls. VoIP is a core technology that drives everything from voice-chat software loaded on a desktop PC to Mac full-blown IP-based telecommunications networks in large corporations. VoIP is gaining popularity among small business owners for good reasons: It costs less than conventional business phone service — often a lot less.

VOIP is now a mature proven technology that until now had only been implemented in large corporations and businesses where it has been deployed on their internal Networks. VOIP is presently the state of the art in business communications. VoIP is benefiting from consumer interest in bundled services from their cable companies as well.

VoIP is techspeak for “voice over Internet protocol,” but it could spell “saving big bucks” for your business. VoIP is especially popular with long-distance calls. Voip is significantly less expensive than typical telephone long distance packages, plus one high speed Internet connection can serve for multiple phone lines with no loss in functionality, reliability, or voice quality and VoIP is great for travelers.

The Best VOIP service for you really does depend on your needs and how you will use the telephone service. VoIP is no longer a technical novelty, but a real business for a growing number of for-profit organizations that sell and service and VoIP connectivity. VoIP is a revolutionary technology that has the potential to completely rework the world’s phone systems.

VOIP is cheaper because it unregulated and uses low-cost commodity networking, and the infrastructure is subsidized by cable TV and POTS subscribers who are paying too much. The primary reason for migrating to VoIP is cost, as it equalizes the costs of long distance calls, local calls, and e-mails to fractions of a penny per use. A key point to remember is that VoIP is built on already established equipment and applications. As an added bonus, it’s also cheaper, because VoIP is free of the endless government regulations and tariffs imposed upon phone companies.

Trojan Horse, we all have heard about the term but what exactly is it? In Computer terminology, a Trojan Horse is a destructive program the secrets run a series of code silently in a background of the computer without the user knowledge. For example, it may insert a virus in the host computer and becomes a part of “botnet” but unlike viruses, they do not replicate themselves and they can be very dangerous.

Trojan horses programs can be tricky. Who hasn’t been online and had an advertisement pop up claiming to be able to get rid of some nasty virus in your computer? Or, even more frightening, you receive an email that “alerts” there is a new virus which can threaten your computer.

In most cases, the sender promises to quickly eradicate, or protect, your computer from viruses if you simply download their “free”, attached software at that moment into your computer. You may be skeptical but the software looks legitimate and the company sounds reputable. You proceed download the software and in doing so, you have just potentially exposed yourself to a massive headache and your computer to a laundry list of ailments.

When your computer is infected by a Trojan, certain things may happen. Some Trojans are annoying while other are malicious. Some of the less annoying Trojans may choose to change your desktop settings or add some silly desktop icons. The more serious ones can erase or overwrite your computer data, corrupt your files, spread viruses, spy on your browsing habits, log keystrokes to steal your passwords and credit card numbers, phish for bank account details (which can be used for criminal activities), and even install a backdoor program which allow the creators of the Trojan to get into your computer anytime they want.

To increase your odds of not encountering a Trojan, follow these guidelines:.

1.Remain diligent

Trojans can infect your computer through rogue websites, instant messaging, and emails with attachments. Do not download anything into your computer unless you are 100 percent sure of its sender or source.

2.Update you operating system frequently. If you are running a Microsoft Windows operating system, this is essential.

3.Install a reliable anti-virus software. It is also important that you download updates frequently to catch all new Trojan Horses, viruses, and worms. Be sure that the anti-virus program that you choose can also scan e-mails and files downloaded through the internet.

4.Consider installing a personal firewall. A firewall is a system that prevents unauthorized use and access to your computer. A firewall is not going to eliminate your computer virus problems, but when used in conjunction with regular operating system updates and reliable anti-virus software, it can provide additional security and protection for your computer.

Nothing can guarantee the security of your computer 100 percent. However, you can continue to improve your computer’s security and decrease the possibility of infection by consistently following these guidelines.
