There are a lot of kids from 1st grade to college that could use some help with their schoolwork. Parents are often not able to give them the help and attention they need to get them back on track on a particular subject. A tutor is the perfect solution.

While there are many people who will tutor locally, in the student’s home, or their own house, the idea of an online tutor is still fairly new. If you have been tutoring kids in your neighborhood, taking your tutoring job online to attract more clients may be a great idea.

If you haven’t worked as a tutor, but this sounds like an interesting idea, take a look at your skills. Are there particular subjects in school that you excelled at?

You will need a website to promote your service, as well as a way to communicate with your young clients and their parents. Let’s take a look at a couple of different ways you could tutor your students online.

Email
Your students can simply email you questions they have. You answer the email and send them exercises and practice tests this way. Even if you are not using email as your main means of communication, keep it in mind when you want to get something to your students while they are not online, or to send them exercises and other files.

Chat Program
Using a chat program will give you more one-on-one interaction with your student. You are able to respond to their questions immediately and will also get feedback from your students. You can check right away if your student understands the problem you are explaining. The students can also ask follow up questions immediately.

Instant Messenger
Instant Messenger works very similar to a regular chat program. There are quite a few instant messengers available for free download. You get the benefit of the chat software without having to install it. Most kids will already be familiar with using Instant Messenger, making it easy to get started.

Message Board
The message board is another great tool to stay in contact with your students. Just like email students will be able to ask you questions any time of the day and you can respond during your regular working hours. If you have a group of students on a similar subject, they may benefit from being able to read and discuss their questions among themselves in addition to getting help from you.

Video Conferencing
Video Conferencing is as close as you can get to being in the same room with your students. You will be able to see your students, observe how they are doing and are also able to read their body language, which can help you determine if your student understands what you are talking about or not. Video Conferencing services have become very affordable over the past year, making this a viable option for you as an online tutor.

You could even offer a subscription-based service that would give students and their parents access to a database of tutorials, articles, FAQ’s and other resources compiled by you to help the kids with their school work. If becoming an online tutor sounds like something you are interested in doing, give it a try. Get the word out and start accepting a few students.

Things have come an awful long way in telecommunications since Alexander Graham Bell was awarded the patent for the first telephone in 1876. In the modern age, traditional public switched telephone networks have been superseded by a powerful convergence between telephone systems and the internet. VoIP (Voice over Internet Protocol) stems from that convergence. It is method for transmitting the voice sound signals in telephone calls over the internet using compressed packets of data. In effect voice sounds are converted to digital signals at the sender end, transmitted as digital data packets and then reconverted into sounds at the receiver end. The digital data packets contain the IP addresses of both the sender and the receiver. The old circuit switched networks had no need for this information as everything went along the same pre-determined route. In contrast, VoIP data traffic traverses the internet along different routes depending on congestion and other factors. This both adds flexibility to telephone communication and significantly reduces call costs.

VoIP emerged as a way of communicating for ordinary users in 1995 when Vocal Tech Communications introduced their IP telephony service in America. The protocol’s popularity grew significantly in the four years to 1999, when it facilitated lower cost calling on national long distance networks. That year was also significant because Mark Spencer (now Chairman and CTO of Digium) invented Asterisk, an open source telephony engine that would allow each computer to potentially become a PBX (private branch exchange) in it’s own right, opening up the possibility for business voip users to create more complex routing services that connected to traditional telephone systems. Another significant development came in 2002 when Skype launched its peer to peer telephony application, creating a growing online network of now over 440 million users. In the current market place, Skype competes against other established VoIP protocols such as SIP (Session Initiation Protocol), a multi-user signaling protocol that allows a wide variety of media content. As business clients switch their telephone systems over to VoIP, the number of hosted PBX users and calls has gone up dramatically. In 2007 there were around 860,000 hosted PBX users, but the market is still growing. In fact, research group Frost and Sullivan have suggested that there could be 4 million hosted PBX users by 2013. Each of these hubs could in turn be routing thousands of calls. Nevertheless, without help from services like Telespeak in the UK, many small and medium enterprises are scratching their heads about how to cost-effectively migrate their telephony systems to VoIP without necessarily junking existing hardware.

Contemporary definitions of VoIP distinguish three main parts. Interior VoIP means each company’s own local ethernet connected phone systems. Of course the term ‘interior’ is slightly deceptive here as online users can be plugged in anywhere in the world with different extension numbers. Meanwhile Exterior VoIP is what routes calls to distant company locations or the traditional Public Switched Telephone Network (PSTN). In effect this eliminates the need for separate phone lines, so users may not know they are using VoIP. The third part features hybrid technologies, where the service provider hosts the switch for the interior company and individual extensions come from the internet to the desktop. VoIP can therefore be used as a powerful and flexible ip telephony architecture reducing costs greatly for end users.
