Telephony is the technology associated with the electronic transmission of voice, fax, or other information between two or more parties using systems associated with the telephone. So then what is internet telephony? Internet telephony is basically the use of the Internet rather than the traditional telephone company infrastructure to exchange spoken or other telephone information. Internet telephony integrates telephone services into computer networks.In essence, it converts analog voice signals into digital signals, transmits them, and then converts them back into analog voice signals. Voice over IP (VoIP) is a common form of this service.

 

 How It Works?

Internet telephony transmits messages using data packets. It starts when a caller or called party speaks into a microphone, telephone or other Internet-connected voice device. The message, which is in analog signal, is converted into digital signal or computer-readable data and sent in discreet packets to the destination, reassembled and reverted back to analog signals.

The different ways internet telephony can be used:

1. PC-to-PC: this is where both parties are communicating using a computer.

2. PC-to-Phone: This is where one user is using their computer microphone and the other user is using their telephone.

3. PC-to-Fax

4. Phone-to-Phone: Internet telephony can be used to send fax transmissions to a physical fax machine.

Each search engine has its own database of web documents. Items are continuously added to the site by a program called a spider. Apart from finding information, a search engine site may also provide features such as free e-mail service, chat rooms, news and facilities for online shopping. Some of the best-known search engines are: Yahoo!, Excite, MSN Search, Google, etc.

Once the IRC is accessed, the user can find out what topics are being discussed and how many users are involved.  The user can then search for a channel that suits their interests.  

 

How to connect?

In order to connect and chat with other IRC users, you must either have an IRC client or a web interface that connects you to IRC servers. There are numerous software IRC clients that enable users to connect and communicate to other IRC servers. IRC commands that can be used while connected to an IRC server. For example, /clear – clears the text from the current window and /help - brings up a list of commands or the help window.

Advantages and Disadvantages of Internet Telephony

There several benefits of Internet telephony, as well as drawbacks.

Galesha Henry's insight:

Benefits of internet telephony

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. 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.

3. Internet telephony also offers a wide range of features and services that are not found on traditional landline phone. Just a few of these amazing features are text voicemail, video voicemail, and voicemail to email, call parking, and the busy line feature.

4. Scalable: The software oriented nature of IP telephony makes it easily scalable, making it possible to integrate other services and applications as well. Adding a new phone to the already running system of IP telephony doesn't require an additional new line. It can be directly incorporated in the system, within the existing infrastructure, which is not in the case of traditional phones.

5. Toll-Free Access: While US toll-free numbers are generally not accessible from outside the US, Internet calling enables users to reach toll-free numbers from anywhere in the world.

 

Disadvantages of Internet Telephony

1. Unreliability: 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.

2. Emergency calls: When traditional 911 calls are made, the emergency dispatch operator is able to see the exact location of the caller due to the direct relationship between the number and an address.However, there is no such fixed relationship with Internet telephony and location.IP addresses generally cannot be pinpointed with the accuracy needed for 911 calls.

3. 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.

Advantages of IRC:

1.  Easy to use:  One of the major advantages of the IRC over other similar chats is that IRC is extremely easy to use. It only takes a few minutes of work to set it up and you're ready to go. Once it is set up it takes only a few moments to connect the next time you use it.


2.  Easy to talk:  Talking on IRC is extremely easy. Just join a channel and after that you can talk as much as you want. The good thing about it is that you can join multiple channels and you can talk to multiple persons at once without any difficulties. 
3.  Informality:  People can speak their minds freely.

 

Disadvantages of IRC:

1. Cyber bullying: Persons within the chat may be picked on or bullied by others in the chat, which may lead to depression or suicide.

 

2. Exposure: The user can get quick help, and complicated issues are presented in reductive terms.

 

3.  Informality: Hyperbole, jokes, and sarcasm may be misunderstood.

How it works

When a person view a newsgroup message, they will notice that, at the end of the message will be a "Reply" link.  The user must click reply to be able to send in a response to the message they have just read. However, the user has to first submit a screen name and a password. The user must ensure that the email address submitted is not used for their important, private email messages because in publishing a newsgroup message, the email address will most likely be bombarded by many responses, including spam messages. 

cassania kelly's curator insight, October 16, 2014 9:16 PM

 Advantages of newsgroups
Newsgroups are similar in some ways to mailing lists, but they tend to have a better structure, which makes it more likely that they will be around for much longer than a mailing list. 

It is also easier to find a newsgroup, and they sometimes have a moderator, who is someone who makes sure that things stay on track and do not disintegrate into something that is socially unpleasant.

More often than not, you will be able to find a FAQ (frequently asked questions) section on a newsgroup, which is always helpful for those who are not sure of anything. These questions tend to be the ones that are asked repeatedly and so negate the need for constantly answering the same question. 

 


• Disadvantages of a newsgroup
A newsgroup is not as quick as an email or even a mailing list. Very often there will be a delay of at least a day, often longer, before a response is given.

Another disadvantage to a newsgroup is that the information on them is submitted by people who may have no real idea of what they are talking about, so you need to be aware of this potential flaw and keep your mind open to alternatives, and to be prepared to do some more background research if it is important.

A serious disadvantage to newsgroups is that they can sometimes attract people who you wouldn't give the time of day to if you were to meet them in person. This is especially worrying if children have access to newsgroups.

Advantages and Disadvantages of IRC

Advantages and Disadvantages of IRC | Internet Tools | Scoop.it
Galesha Henry's insight:

Advantages of IRC

1. IRC is decentralized: There is no single company controlling IRC (in contrast to gchat or Facebook chat or AIM, etc.) Therefore, anyone can set up their own server and use it however they like.

2. IRC's channel paradigm is very flexible and robust: allows for real-time discussion with up to hundreds of people at once.

3. Privacy: IRC has the concept of access levels and complex channel modes. For example, users may be banned from a channel based on their IP address, or a channel may be secret (not showing up in the list of channels on the server) or private and require an invitation or a secret code to enter.

4. Meeting new people: persons are able to meet and communicate with new people all over the world on IRC.

 

Disadvantages of IRC

1. Informality: hyperbole, jokes, and sarcasm not only may be misunderstood by some persons in the chat.

2. Chat bytes: The chat client line length and buffer limits mean that all "discussion" is necessarily limited to chat-sized bites of words.

3. Freedom: it may be difficult to organize and control discussions because the conversations often veer off topic, exactly at the whim of the participants.

4. Cyber bullying: persons within the chat may be picked on or bullied by others in the chat, which may lead to depression or suicide.

Advantages and Disadvantages of Telnet

There are a number of advantages and disadvantages of telnet. Here are some of them.


Via Galesha Henry
Galesha Henry's insight:

Advantages of Telnet

1. Accessing Remote Computers: One of the biggest advantages of Telnet software is that it allows remote access to someone else's computer. While it is not exactly like sitting in front of someone else's computer and using it, it does provide you with the ability to access the computer's data through a text-based interface. Instead of traveling to another location to look at a remote machine, you can view it from the comfort of your home or office.

2. Saves Time: Telnet saves time because instead of physically traveling to another person's home, you can perform any task on his or her computer almost immediately from your computer.

3. Router configuration: Since it uses plain text it is very easy to fix problems. This allows for more access and less problems with data transmission.

4. Universal: Telnet can be used on any computer. Even older systems can connect to newer machines with different operating system versions.

 

Disadvantages of Telnet

1. It's not secure - everything is sent in plain text be it over a local network or over the Internet. Its disadvantages are that what you type is sent to the remote machine just as you type it. This means that anyone ‘'sniffing'' on the connection anywhere between you and the remote machine can read anything you type, including your passwords.

2. It is old: It is text based only, there are no graphics or colours which makes it boring.

3. It may difficult to use: it is command driven therefore there is no mouse so this may make it difficult for some persons to use. Additionally,You have to know how to run programs at the other end because there might be a different Computer System, different Commands or a different Language – Programming.

What is IRC? (Internet Relay Chat) How do I connect to it?

Galesha Henry's insight:

Internet Relay Chat (IRC) is a protocol for live interactive Internet text messaging (chat) or simultaneous conferencing. It is mainly designed for group communication in discussion forums, called channels, but also allows one-to-one communication via private messageas well as chat and data transfer, including file sharing.IRC provides a way of communicating in real time with people from all over the world. It consists of various separate networks (or “nets”) of IRC servers, machines that allow users to connect to IRC.

 

How does it work?

Generally, the user runs a program (called a “client”) to connect to a server on one of the IRC nets. The server relays information to and from other servers on the same net.Once connected to an IRC server on an IRC network, you will usually join one or more “channels” and converse with others there.

Telnet

Telnet | Internet Tools | Scoop.it

Via Galesha Henry
Galesha Henry's insight:

Telnet is a network protocol used on the Internet or local area networks to provide a bidirectional interactive text-oriented communications facility using a virtual terminal connection. Wow, that’s a mouthful. Let’s break it down. Telnet is basically used to communicate with other computers and machines in a text base manner. Telnet stands for 'telecommunications network', and was built to be form of remote control to manage mainframe computers from distant terminals. A telnet session looks something like this:

 I know, not really visually exciting.

 

Some characteristics of Telnet:

1. Bidirectional: That means Telnet is not one-way; it can be used to send or receive messages.

2.Text-oriented: Telnet is a text-only protocol; you won’t see graphics nor will be able to transfer files with Telnet.

3.Interactive: That means Telnet basically expects a live user on one end of the line.

 

How does it work?

The Telnet program runs on your computer and connects your PC to a server on the network. You can then enter commands through the Telnet program and they will be executed as if you were entering them directly on the server console. This enables you to control the server and communicate with other servers on the network. To start a Telnet session, you must log in to a server by entering a valid username and password.

Galesha Henry's insight:

Well that was alot to take in. Let's Recap. Internet Relay Chat, Telnet and Internet telephony are all internet tools in which persons can communicate over the internet. All three also have the characteristic of being bidirectional and interactive. However, they are all very different from each other. Internet Relay chat allows for persons to have live interactive text messaging chat over the internet, whereas, Internet Telephony integrates telephone services into computer networks. However, Telnet allows a user on one computer to log onto a remote computer that is part of the same network. While, Internet telephony and Internet Relay chat have the excitement of graphics, Telnet is command-driven, therefore it has has no graphics or color.
