For his week’s NCT tutorials we learnt to use different media tools that everyone commonly uses. Social tools that we must have basic knowledge of. Like Skype use Voice over Internet Protocol (VoIP),the cost is apparently cheaper than using regular telephone calls. So this is a really good way to save money!
What’s more, the costs of VoIP are lower because it is billed per megabyte (MB) whereas telephone calls are billed by the minute or second. I find this information interesting as it shows the difference between technologies now and in the past. Imagine the cost to calls overseas, but now you don’t have to take it into consideration as the cost is so cheap!
I can totally imagine that in the near future our phones will change to use VoIP, as the costs are SO much cheaper. However in emergencies, the phone cannot use VoIP so it will have to be merge of what the phone has now.
Singapore needs to keep wireless@sg, so people can use VoIP. But as you know it, wireless@SG is not stable, sometimes you can go on or off. Of course, the phone bills would have to go down, but there would be challenge between the three TelCos as to how low they would go!
Here is a video to tell you more about VoIP:
I love wikipedia because it is convenient to find all your needed information in one place. Here is more about VoIP. Benefits of VoIP is obviously its operational costs and its flexibility. The disadvantages about using VoIP is it is susceptible to power failure and it cannot be used in emergency calls. So handphone are useful in such situation!
