Benefits of Internet Telephony

The video above talks about some of the advantages of Internet 

Telephony these Include:

 

(1) Low Cost:  The main benefit of internet telephony is the low cost. PC-to-PC calls are generally free, and PC-to-Phone connections are generally a fraction of the cost of a traditional phone line. 


(2) Video: The ability to transmit and watch video is huge plus for Internet telephony, a technology that mankind was seemingly promised years ago by science fiction movies and magazines.


(3) Portability: One only needs a laptop and an internet connection to use Internet telephony, whether in an airport, a library, or a fast-food restaurant.


(4) Features: Many of the features available for a fee with a traditional phone line, such as caller ID, call waiting, and call forwarding, are free with Internet Telephony.


(5) Area Code:  A subscriber to a VoIP service is able to assign any area code to his phone number for incoming calls. For instance, even though a subscriber may live in Chicago, Illinois, where the area code is (312), he can assign his phone number an area code of (303), the area code of Denver, Colorado. This may benefit a Denver resident who frequently places calls to the subscriber and no longer needs long-distance service to do so.


The disadvantages Include: 


(1)  Electricity: Traditional phone services functions with or without electricity. Not so with Internet telephony. If the power goes out, taking the Internet connection with it, no phone service is available. Backup generators can provide emergency electricity for a limited time, but no amount of electricity can help an Internet connection that has gone down.


(2) Compatibility: VoIP connections have been known to have issues with devices such as satellite television receivers and conventional modems that need to dial an outgoing number. The VoIP line is set up for voice, not for data. However, this problem is not as widespread as before, as companies are increasingly making devices that are compatible with VoIP lines.


(3) Sound Quality: Sound quality is not a huge disadvantage as advancements are continually made in technology, but it should be noted that an analog phone line offers better clarity and consistency. As mentioned previously, Internet telephony is prone to losing packets during transmission, resulting in dropouts.

Mailing Lists-What Are They

Mailing Lists-What Are They | Internet Tools | Scoop.it

A mailing list is a way of forwarding messages to others who are interested in the same research or interests as you. You send your message to the list and it is sent to everyone who has subscribed to that list. And everything that anyone else sends to the list will be sent to you. It is a great way to find others who are researching in the same area.

 

A mail list does not have an address that you can go to. It is not a place on the Internet. It only forwards email messages. Mailing lists are can be an open list: meaning anyone can post and view most content or it can be a closed list: meaning that you must be a subscriber to the list before you can post/mail anything. This option is normally decided by the administrator of the mailing list. Most mailing lists are closed to prevent spam from being sent out from the list. 

 

There are two common types of email mailing lists:

 

(1) Announcement lists, which are used so that one person or group can send announcements to a group of people, much like a magazine publisher's mailing list is used to send out magazines.

An example of this would be a newsletter.

 

(2) Discussion lists:  used to allow a group of people to discuss topics among themselves, with everyone able to send mail to the list and have it distributed to everyone in the group. This discussion may also be moderated, so only selected posts are sent on to the group as a whole, or only certain people are allowed to send to the group. An example of this would be a group of model plane enthusiasts might use a mailing list to share tips about model construction and flying.

What is Internet Relay Chat?

What is Internet Relay Chat? | Internet Tools | Scoop.it

Internet Relay Chat (IRC) provides a way of communicating in real time with people from all over the world. It consists of various separate networks of IRC servers, machines that allow users to connect to IRC. IRC is very similar to text messaging, but designed around communicating with large groups of users instead of one on one. 

 

History of Internet Relay Chat:

 

(1) In 1988  the first Internet Relay chat was created by  Jarkko Oikarinen of of Oulu University in Finland.

 

(2) In 1991 IRC was used in the Gulf War and Russian Coup attempt.

 

(3)RFC(Request For Comments)1459 published in 1993

 

(4) The “Great Split” in 1996 where IRC split into IRCnet and EFnet.

 

There are two major features of Internet Relay Chat:

 

(1) Clients: An IRC client is the vehicle that connects you to the global network of IRC servers. A variety of applications are available, so, whether you are on Windows, Linux, MacOS, or one of dozens of other operating systems, or even on your smartphone you can find a client.

 

(2) Networks: IRC is organized into numerous independent networks, all with different audiences, geographical reach, and management. Besides the major networks, there are also many smaller networks that serve either a niche audience or a small geographical region. 

 

Benefits of Internet Relay Chat

 

(1) Lightweight and flexible chat system.

 

(2) Basic standards are widely used and most clients can connect to most servers.

 

 (3) Loose standards lead to a wide variety of clients and servers.

 

Drawbacks of Internet Relay Chat are: 

 

 (1) Very loose standard leads to incompatibility between servers, dividing up networks.

 

(2) Very loose standard leads to incompatibility between servers, dividing up networks.

Internet Telephony

Internet Telephony | Internet Tools | Scoop.it

What is Internet Telephony?

 

Internet telephony refers to a broad range of services over the Internet that were traditionally performed over the telephone line. These services include transmitting voice and or video.

 

There are varying terms and phrase which also hold the same meaning such as:

(1) VoIP (Voice over Internet Protocol)

(2) IP Telephony

(3) Broadband telephony 

(4) VoBB (Voice over Broadband)

 

How Does Internet telephony work? 

 

Transmitting voice and video via the Internet works much in the same way that all transfers over the Internet work: in packets. Speech and/or video are sampled by the computer and are typically compressed to save space.

 

There are a number of different ways to compress audio using technology called “CODECs,” or compressor/de-compressor. For example, a speech CODEC selectively subtracts sounds that are outside the frequency of human speech, making the sample size smaller without sacrificing too much quality.

 

The compressed samples are then broken into small packets. Generally, an IP packet contains around 20 to 30 milliseconds of audio. These smaller packets are then sent via the Internet to their destination, where they must be re-assembled. As a result of this technological process, there is a delay from end-to-end of anywhere between 100 and 400 milliseconds, perfectly acceptable to carry on a conversation.

 

Different ways to use Internet Telephony.

 

(1) Pc-to-Pc: The goal of Internet telephony is to be seen and or  heard, so one needs a camera or microphone to interface with the computer. Many webcams have a built-in microphone, killing two birds with one stone. Using programs such as Skype, AOL Instant Messenger, or Yahoo! Messenger, users can connect to anyone else using the same program for real-time video chatting over an existing Internet connection. These programs are normally free of charge.   

 

(2) Pc-to-Phone: Some programs, such as Skype, allow a computer user to dial an actual phone number, so that one user is using their computer microphone and the other user is using their telephone (be it cell phone or LAN line). These services are not free;  Skype charges users about$2.99 a month for the ability to dial a phone number.

 

The Magic Jack is a small device that plugs into a USB port on any laptop or computer with an internet connection. The Magic Jack has a standard phone plug that any regular phone can then plug into to make calls to anywhere in the US or Canada for a yearly fee of $20. The quality of the call is said to be as good as a cellular phone call. Later versions of Magic Jack no longer needs a computer but just a phone line to connect to other phones. 

 

While Magic Jack calls originate on the internet, they do eventually need to travel through a conventional phone line to reach their destination. VoIP providers do not directly connect calls to the traditional lines, but depend on third-party carriers who "off-load" the call from the VoIP provider to their own lines and then transmit the call along the traditional phone lines until it reaches the recipient.

 

(3) Phone-to-Phone:  Companies such as Vonage and VoicePulse offer phone-to-phone service for a monthly fee. Typically, the user needs to purchase a device that plugs into the user's Internet router.  Any phone can then be plugged into the device and used like normal, but at a fraction of the cost of typical phone companies. Surprisingly, even a rotary phone can be used 

 

(4) Mobile Phone-to-Pc or phone:  Many smart phones are able to use a wi-fi network when available, offering faster speeds than its own cellular network. Skype provides a free application for smart phones which utilizes the phone's built-in camera and microphone and allows users to call other Skype users for free or phone numbers for a small fee. There has also been a magic jack app in recent times that function the same as the regular Magic Jack all that is needed is a internet connection.
