VoIP is similar to IM in the sense that you can use it to communicate, but it is not building a conversation, it's sending sounds. You will need a headset/speakers and a microphone.

Online Marketing

Internet marketing, also known as web marketing, online marketing, webvertising, or e-marketing, is referred to as the marketing (generally promotion) of products or services over the Internet. Internet marketing is considered to be broad in scope because it not only refers to marketing on the Internet, but also includes marketing done via e-mail and wireless media. Digital customer data and electronic customer relationship management (ECRM) systems are also often grouped together under internet marketing.

The Pros And Cons Of Using A Mobile Phone in Public

 
Bad

Phones can interfere with equipment in Hospitals. A 1997 ‘New England Journal of Medicine’ study found that talking on a phone while driving increased the risk of an accident by 4%. This is almost equal to the danger of driving drunk.

Many people go libraries to do work. When someone is on their phone in a library it can be very distracting. When people go out to a restaurant, they feel entitled to a relaxed atmosphere, as some mobile phone users use language inappropriate for anyone to hear, especially young children.

Mobile phone users will usually multitask, trying to carry on a conversation while using an ATM, driving or buying something from a shop. Their divided attention becomes an obstruction to the cashier and an inconvenience to those behind them who have to wait longer.


Good

Some argue that having 999 at the touch of a button is critical to maintain personal security. Mobile phone bans impede drivers’ ability to report an accident, road rage incident, medical emergency or crime. Drivers assert the importance of calling for directions if lost or receive help if their car breaks down.

As genuine emergencies do occur, some calls can’t wait. People who have sick or elderly family members, parents expecting an important call from their child and those in the middle of a crisis believe it’s acceptable to leave their phones on in public.

Cell phone bans may intrude on their personal freedom. As they pay high monthly price for this communication option, they believe they can use the devices wherever and whenever they choose.

Voice Over IP (VoIP)

Voice over IP (VoIP, or voice over Internet Protocol) commonly refers to the communication protocols, technologies, methodologies, and transmission techniques involved in the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet.

Early providers of voice over IP services offered business models (and technical solutions) that mirrored the architecture of the legacy telephone network. Second generation providers, such as Skype have built closed networks for private user bases, offering the benefit of free calls and convenience, while denying their users the ability to call out to other networks. This has severely limited the ability of users to mix-and-match third-party hardware and software. Third generation providers, such as Google Talk have adopted the concept of Federated VoIP – which is a complete departure from the architecture of the legacy networks. These solutions typically allow arbitrary and dynamic interconnection between any two domains on the Internet whenever a user wishes to place a call.

VoIP systems employ session control protocols to control the set-up and tear-down of calls as well as audio codecs which encode speech allowing transmission over an IP network as digital audio via an audio stream. The choice of codec varies between different implementations of VoIP depending on application requirements and network bandwidth; some implementations rely on narrowband and compressed speech, while others support high fidelity stereo codecs. Some popular codecs include u-law and a-law versions of G.711, G.722 which is a high-fidelity codec marketed as HD Voice by Polycom, a popular open source voice codec known as iLBC, a codec that only uses 8 kbit/s each way called G.729, and many others.

VoIP is available on many smartphones and Internet devices so that users of portable devices that are not phones, may place calls or send SMS text messages over 3G or Wi-Fi.

The Effects Of 4G

The Effects Of 4G:

The introduction of 4G will allow everyone to browse the internet of their mobile phones much faster and will diminish "Buffering." However, this was said about 3G when it came out and within quite a short period of time, the amount of time it took for the majority of the population to get it, it became very slow, hence the need for the move to 4G. So basically, 4G will be very good, but we will soon need "5G" or something else that will allow fast browsing.

4G has and will benefit companies and businesses also, because of the huge usage of emails etc that help businesses in contacting their partners and othe businesses.
