The communication devices are devices that generate and / or receive analog or digital signals, enabling the exchange of information. These media were created by humans throughout their historical evolution.
In a broad sense, a communication device is any device that can be used to transmit a message.
In current times they are constituted as the main protagonists of communication technologies (ICT).
Computers or computers are the most representative communication devices.
These electronic machines have been designed to receive, process data and convert it into information.
As communication devices, computers are faster and more efficient compared to other traditional devices such as the telephone and the mail.
The 9 examples of communication devices
1- The modem
It is a device that transforms digital signals into analog through a process called modulation, and analog into digital through demodulation.
Its function is to send the modulating signal through another signal called a carrier. The modem arose out of the need to communicate computers to share data between them.
2- The switch
It is a digital device that serves for the interconnection of computerized equipment, or segments of a network made up of them. Also called a switch.
It operates logically by merging sections of the same network, filtering information in order to optimize it in terms of performance and security.
3- The router
It is also called a router or packet router. This device allows the use of several IP addresses within the same network, allowing the creation of subnets.
4- The cell phone
It is a wireless electronic device for accessing mobile telephony. It is called cellular because each of the repeater antennas that are part of the network is made up of cells.
5- Long distance devices
These types of devices are connected through an elaborate network that achieves long-distance communication by having a built-in LAN.
Long distance telephone calls occur by digital modulation of analog carrier signals.
6- Satellite telephony
Satellite phones allow efficient communication in the most remote places on Earth.
These devices use the same mobile technology by locating low-orbit satellites spinning in space.
When the link to the satellite is established, the signal is redirected to a communication station on earth.
7- Based on VOIP
VOIP technology consists of transmitting telephone signals back and forth over the Internet.
Telephone conversations based on devices of this technology are clearer compared to conventional telephony.
8- The GPS
This device allows to determine the exact and precise position of an object on Earth. It is used to locate children, the elderly and people with disabilities.
It is also used for the location of vehicles as a preventive measure against theft.
9- Augmentative devices
Augmentative or assistive, are communication devices that give a voice to people with disabilities, allowing them to express themselves without the need to be assisted by other people.
