Virtual Private Networks, Internet TV and Other Things

VPN, or Virtual Private Networks, are networks that make use of the internet to offer secure access to a network. What it does is summarize transfers of data between two (or more) networked devices so that the data that is transferred can remain private. VPN is therefore an ideal platform for viewing international television.

When using a VPN with an internet TV channel provider, a wide variety of different television channels from the US, UK and Canada are accessible online which were previously only available to residents of that country. It allows for expatriates globally to watch broadcasts from their computers via the internet. This is a very unique and useful system. And here’s why:

How a VPN works is as follows: only a personal computer and internet connection can be used. An account must then be opened with an internet TV channel provider, and within minutes, the VPN can be activated. This system allows for access to the internet without any restrictions or circumventing blocks that make it difficult to make international calls via Skype or MSN, and eliminates internet censorship in places like the Middle East, Dubai and China by making previously blocked and censored channels, web sites and blogs available.

To set up a VPN is easy! You don’t need to be an IT technician to enable this; all you need is a quality internet TV provider and a working internet connection.

Other advantages of having a VPN service  are having protection when using wireless hotspots, complete anonymity as your IP address cannot be tracked, and being able to access online gambling sites, which are now restricted in many countries.

All that said, however, perhaps the biggest advantage of having a VPN is the fact that it is one of its sidebar features is free long-distance phone calls, which can be a major factor despite the existence of Skype and Yahoo.

A word of caution, watching TV over a VPN does require an Internet connection with a speed of at least 1mbps so it’s critical, that you check anticipated speed, not theoretical speed before signing up to any package offering TV over the Internet, most users need a connection speed between 1.5 and 2 MB to guarantee live TV streaming without any interruptions. At peak times, download speeds usually by up to half, making viewing impossible.

There are several types of VPN’s:

PPTP VPN (point-to-point), which is a simple method of software-based VPN systems which makes use of an already existing internet connections. It essentially creates a “tunnel” between two users.

Similarly, STS (site to-site) VPN makes use of each site with its own internet connection, which doesn’t necessarily have to be the same.

MPLS is an IPS-tuned VPN that needs two or more sites connected by the same ISP. It stands for Multi-Protocol Label Switching.

Some VPNs are hardware-based, others software-based, and certain VPNs are Firewall-based.

E-commerce Explained

E-Commerce is way of doing business transactions electronically.  The word electronically in this context means that in E-Commerce business transactions gets completed via electronic medium. This electronic medium mostly uses computers on Internet. The transaction may also be done through a mobile device, smartphone, iPad, Kindle, Android Tablet then it is mobile commerce. Mobile commerce is a subset of E-Commerce.

Several simple example of E-Commerce includes:
An individual purchases a book on Internet
An individual withdraws funds from ATM
A retailer orders merchandise using an EDI network or suppliers extranet
An individual or business calls a toll free number and orders the requirements using the seller’s interactive telephone system.
A manager orders office supplies for his office using Internet on a commercial website set-up for the seller.
An individual reserves a travel ticket or a room in a hotel using the Internet by surfing the related website using a few clicks of mouse.

A Complex examples could be:
A student visits the website of a bookstore on Internet and makes inquiries about the availability of an out of stock book. The bookstore employee receives the the enquiry and sources a digital copy of the book and responds to the enquiry with the  option and costs. The student agrees and uses a payment processor to pay for download and the book store employee gives the student a key to download the digital book. The bookstore employee harvests the students contact details and areas of interest and adds to a database which will email customers when books of possible interest arrive in the store or are put on sale.

E-Commerce transactions are great for small business as well as large because payment is made before goods are made available for digital download. The only things you should be aware of is:

a) Ensuring that your payment processor links are set-up properly

b) Ensuring that your server for the sales page and downloads is not going to crash because of  bandwidth or data transfer issues with your hosting company, or limitations in your own server set-up.

c) Ensuring that money back guarantee’s are honoured in a timely and friendly manner.
