What is IM (Instant Messing) and the Advantages of it

Instant messing is the involvment of people talking to eahother in a real time by typing and receiving messages.
IM is a form of real time-communication between two or more people which enables them to have a virtual conversatrion. This is quite popular as it allows quick and easy communtication in real time, people are able to collaborate and discuss their views, the users gets to decided  who they wish to engage with and they are able to set a status so that people know if they are available to talk or their busy, you can use through cartain moblie phones, PDA and other portable device. 

The Disadvantage 
To use IM you would need internet access. If the connection is slow this impacts on the real-time feature also the over use of IM could result in less face-to-face contact with people.
There is lack of emotion so people may misunderstand informations. Writing skills can be affected if the individual uses a lot of text language, the thought of typing my be tiring and you prefer chatting instead. 

What is VoIP(Voice over Internet Protocol)
 This is similar to making a phone call but rather its on a computer, it's also abit like the IM but uses sound instead of text.
This can also be use on a mobile, so can it save an individual from huge phone bills.
To use a VoIP on a computer the user would need headset or speakers and a mictophone, and a webcam if they wish to stream video to other caller.
Mobile phones must have 3G or mobile internet to connect to internet.
If the landline phone is plugged into the internet router this is good as you can make calls free enven international calls.
VolP services providers charge a membership or monthly fee.

Disadvantages
The disadvantages of a VoIP is reliability,VoIP is dependant on wall power, Your current phone runs on phantom power that is provided over the line from the central office. Even if your power goes out, your phone (unless it is a  cordless) still works. With VoIP, no power means no phone. A stable power source must be created for VoIP.
VoIP is susceptible viruses and hacking, although this is very rare and VoIP developers are working on VoIP encryption to counter this.System can crqash in the middle of an important call.
Emergency 911 calls also become a challenge with VoIP. As stated before, VoIP uses IP-addressed phone numbers, not NANP( North American Numbering Plan) phone numbers.There's no way to associate a geographic location with an IP(Internet protocol) address. So if the caller can't tell the 911 operator where he is located, thenthere's no way to know which call center to route the emergency call to and which EMS should respond
