Communication Technologies, also known as Information Technology (I.T), refers to all equipments and tools that are used to process and communicate information. Professionals in the communication technology field specialize in the development, installation and servicing of these hardware and software systems. Individuals who study in this field will develop an understanding of the conceptions, production, evaluation and distribution of communication technology devices.
Communication is the exchange of information through the use of speech, signs or symbols. When early humans started speaking, that was the first mode of communication. Communication over a long distance when people who are communicating are not in direct line of each other’s site is called Telecommunication.
The invention of the telephone and establishment of commercial telephony in 1878 marked a turn around in communication systems and real telecommunication was born. Telephones slowly gave way to television, satellite and finally computer networks. Computer networks have revolutionized modern-day communication and communication technologies.
Communication Technologies are basically the equipments, tools, devices to make it easier for people to communicate and pass information around the globe.
Below are some major technologies enabling an easier and faster way to communicate:
Telephone: This is basically an electronic device designed for the simultaneous transmission and reception of the human voice. Telephone converts sound, usually the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user. Alexander Graham Bell revolutionized the way people communicate with his patent on the telephone in 1876. All over the world, millions of people can talk to each other, expanding businesses and improving relationships that might not otherwise have survived across long distances.
Radio: This involves the transmission, detection, and reception of communication signals consisting of electromagnetic waves that travel through the air in a straight line or by reflection from the ionosphere or from a communication satellite. It is basically a technology of signaling and communicating using radio waves. The radio waves are generated by an electronic device called a transmitter connected to an antenna that radiates the waves, and received by a radio receiver connected to another antenna. The radio receiver is an electronic device that receives radio waves and converts the information carried by them to a usable form clearly using the antenna. Antenna intercepts radio waves and converts them to tiny alternating currents which are applied to the receiver, and the receiver extracts the desired information.
Television: This involves the delivery and transmission of moving images (usually monochrome, two/three dimensions)and sound from a source to a receiver. This type of communication uses an electronic for receiving transmitted signals and usually known as a TV set. It is a mass medium for advertising, entertainment, and news. The TV was introduced to the public in 1946, even though it had been experimented with since late 1920. Television signals are distributed as terrestrial television using high-powered radio-frequency transmitters to broadcast the signal to individual television receivers.
Internet: This is one of the most major inventions in Communication Technologies. The Internet basically opens up a wide range of communication methods and also helps to enhance the existing method. The Internet is a global wide area network that connects computer systems across the world. The creation of the Internet allowed computer networks from around the globe to network with each other using the ISP suite, giving individuals access to an incredible wealth of information. It is a network of networks that consists of private, public, academic, business, and government networks of local to global scope, linked by a broad array of electronic, wireless, and optical networking technologies. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents and applications of the World Wide Web (WWW), electronic mail, telephony, and file sharing.
Communication Technologies have helped to make the communication process more convenient and easier and it has a lot of benefits and advantages when compared to the traditional means of communication and below are some of the benefits of communication technologies.
Accessibility: Communication Technologies helped to make communication more convenient and accessible, especially long-distance communication because to message someone anywhere in the globe, you have a lot of tools in the computer to choose from, for example, email, social networks, etc which delivers the message in a heart-beat.
Social Influence: Communication Technologies, mainly communications via the internet like social networking websites and dating websites, has made easy the process of socializing. Social networking websites help you to keep in touch with friends and family while dating websites help you find someone compatible to be in a relationship with.
Mass Communication: Large organizations like schools and businesses, use electronic communication media to share information with a large number of people, schools can send bulk emails to students to inform them about a certain change in the school or a public holiday. Many higher institutions use electronic communication to maintain a well-informed campus.
Communication for the Disabled: A benefit of communication technology not often noted or discussed is that technology gave the disabled the ability to communicate, facebook for example allows even dumb people to easily communicate and share their opinions to everyone. Communication technology allows for people who have previously not been able to speak to have a voice through specialized computer software.
Long-Distance Communication: Early forms of transferring information across a long distance involves runners who ran messages to and fro between people and training pigeons to fly written messages. The advancement of communication technology has helped to make long-distance communication fast and effortless.
Social Comfort: For people who are socially awkward, computer communications such as online forums and chat rooms can help them create a more fulfilling social life.
Below is a list of a few features of Communication Technologies
Asynchronous Communications: Communication Technologies allows companies, for example, to recruit workers who are in remote locations because asynchronous communications allows them to work together even in different time zone.
Electronic Mail: Electronic mail (e-mail) is widely used to communicate between team members. It has lots of valuable characteristics and features for project management:
Really Simple Syndication (RSS): Communication technologies allow users to subscribe to online news sources to read every update from a single app.
Voice Calling: Communication Technologies allows you to call and speak with someone instantly not minding the distance and time.
Video Calling: Communication Technologies allows for companies and business to call and discuss in real-time with the computer.
Instant Messaging: Communication Technologies allow you to text messages in an instant.
