Communication devices are any devices which aid in the process of communication. Types of communication devices can range from communication aids, like a picture board, to electronic communication, like email.
Runners and homing pigeons are examples of early forms of communication devices. As time passed and technology evolved, faster, more efficient communication devices were created.

Communication devices are separated into types based on the direction of communication. A communication device which only allows for communication one way, like a radio broadcast, is known as simplex. A phone conversation, in which there is communication back and forth but not at the same time, is known as the half duplex system. Communication devices which allow for simultaneous interaction are full duplex systems
Communication aids are communication devices which give people who have trouble speaking verbally the ability to communicate with others. People with disabilities are likely to use communication aids. An example of a communication aid is a picture board which uses pictures to communicate ideas.

Social networking websites, instant messaging, and email are examples of electronic communication. Email is the most commonly used form of electronic communication. Many educational institutions rely on email to communicate information to a large mass of people.

Communication devices require elaborate networking to enable long distance communications. Computers have built-in LAN (local area network) to enable long distance communication. Long distance phone calls are made possible by digitally modulated analog carrier signal

Modern technology has enabled the creation of a myriad of new communication tools, sites and software. Likewise, improvements and additions are constantly being made to existing devices to maintain the highest quality of communication possible. There are many types of communication available; the choice depends on where you are, how much time you have and how much (if any) you prefer to pay.

The capabilities of cell phones have continued to increase since their introduction in the late 1980s. In addition to basic text messaging and wireless phone conversations, many cell phones enable their users to send and receive email, pictures and recorded videos. Bluetooth technology has further increased the communicative value of cell phones, allowing talkers to carry on their conversations hands-free with the use of a small, one-sided headset.

Skype is downloadable software that enables users to make free phone calls and send messages via the Internet. The service also offers video phone calling, allowing users to watch each other in real time while they speak. Use of Skype's free features requires a broadband Internet connection as does its paid features. Both businesses and private individuals have benefited from the convenience and immediacy of Skype's communication tools.

Instant messaging enables users to communicate with each other on the Internet via short written (or sometimes spoken) messages delivered almost immediately after the content are created. Instant messaging is a less cumbersome form of email as well as a faster way of facilitating complete conversations in real time. MSN, Yahoo, Facebook and America Online are a few of the services that offer messaging tools and programs for their users.

Twitter is a popular social networking site created in 2008. While the concept is not unlike similar social sites such as MySpace and Facebook, Twitter is unique in that users can write (or "tweet") messages from either their computer or cell phone in short, concise updates, as often as they please. The concept of Twitter revolves around the idea that people can stay updated on the events of others' lives without spending a lot of time sifting through extraneous information or more elaborate weblogs. Another perk is the fact that Twitter is completely free and requires no special software.

Although email is not brand new, there are definitely new and innovative ways of accessing this tool remotely and without the usage of a computer. Many PDAs and cell phone services offer access to email, with the capability of sending and receiving messages from the devices themselves. This technology can be extremely helpful for those who must stay in constant communication with family members, co-workers or other acquaintances without being bound to larger computers or laptops.

Communication gadget:

Communication devices have been around in one form or another since early in humanity's existence. Even in primitive times before history, people were using methods to communicate with each other. In more modern times, communication devices come in several different formats, and use different styles of communication, as well, to get a message across. Several types of devices are frequently used for communicating

The idea of a communication device is broad, as almost any object can be used for communication. For our purposes, a communication device is anything that can be used to convey a message from one person to another. There have been many such devices over the course of human history.

Even before the written word, drums, fires, and smoke signals were used to relay warnings and other messages across long distances. Later, handwritten notes were sent by courier or via horseback, in a manner similar to a postal service. And in the Middle Ages, the invention of the printing press enabled books and later newspapers to be produced on a mass-market basis, and so they too became effective communication devices

 As the end of the second millennium A.D. approached, major new technologies began to appear. One of the biggest innovations of the 19th century was the telegraph. Later, Alexander Graham Bell would create the first working telephone.

In the early 1900s, researchers discovered how to use the radio waves that pervaded the planet. They eventually learned how to broadcast using these radio waves, so that audio could be delivered directly into people's homes. In the 1950s, television was invented, and in addition to audio broadcasts, people could now view actual visual broadcasts of people and places.

Personal computers first became truly popular in the early 1980s. Not long after that, computers began to be networked with each other, and in the 1990s, the Internet as we know it today was effectively born. The Internet arguably ranks

among the greatest inventions ever made, as it has made communication relatively instant even for people on opposite sides of the planet, and has provided access to even remote parts of the Earth.

The latest trend in online education is to connect tutors and students, from across the world, with interactive software. authorLIVE is one such tutoring environment to provide solutions for the challenges of distance learning.

There is an old cliché: "A picture is worth a thousand words". This holds true for technical communication. Many document sets contain large numbers of screen captures, black-box diagrams, and other explanatory pictures to assist the reader in understanding a concept or action. The most commonly used programs are industry leader Corel Photo XI, Photoshop by Adobe Systems, and GIMP.

For creating vector graphics Inkscape provides more functionality and control than the other programs.

There are many other tools that technical communicators find useful. Dictionaries are one of the most

useful tools any writer can have. A list of online dictionaries is available. For more information on available tools refer to the Technical communication tools category
