Communication Peripherals examples

The peripherals, in computing, are the devices or hardware added (and therefore external) to the Central Data Processing Unit (CPU), whose function is to allow the exchange of information with the outside of the computerized system.

The communication peripherals relate only to those devices that serve to establish a remote data transmission between a computer and another, or between a computer and another peripheral remote. Said communication can be wired or wireless, and according to its technical nature it will have more or less transmission speed and more or less range. Network cards, modems, fax are some examples of communication peripherals.

They are usually classified as internal (they make life inside the computer) or external (they operate as separate entities).

Examples of Communication Peripherals

  • Routers ( Routers ) network. Also known as packet routers, they orchestrate the transmission of data from one network to another, allowing subnets of equipment to be interconnected through network bridges.
  • Network cards (NIC). Attachments, in the form of boards or cards, integrated or not to the computer’s motherboard, whose function is to allow and control the exchange of information between two connected systems, either directly or through other peripherals and subsystems.
  • Modems. Independent peripherals that link a computer equipped with a network card, with another similar one or with a network of them, managing data traffic according to established protocols.
  • Network hubs (HUBs). Devices designed to centralize the cables that communicate to a computer network, expanding the informational signal and allowing to maximize or diversify the scope of the information. At present they have been displaced by the switches.
  • Switches ( Switches ) network. These are digital devices for interconnecting computerized equipment or segments of a network made up of them. They operate logically by merging various sections of the same network or converting various networks into one, filtering information and improving their performance and security.
  • Bluetooth devices. Through low-frequency radio waves, this type of information transmitters and receivers allow the connection of equipment with each other or with various peripherals of all kinds, dispensing with wiring but still maintaining a short communication range and comparatively low speed.
  • Infrared nodes. Through light-emitting diodes, they allow the transmission of information between various equipment specially arranged for it, which requires a very short distance and a specific alignment, which is a disadvantage compared to other more modern data transmission systems.
  • Wifi devices. Similar to the previous cases, but through a system of radio waves of greater range and speed, Wifi systems allow the connection of equipment and devices to vast networks such as the Internet, which allows wireless management of much more ease and amplitude.
  • Life devices. Technology newly developed outperforms the Wifi in speed and agility through the use of light-emitting diodes (LEDs) to interconnect systems, networks, and equipment, replacing the radio waves from the visible light transmission medium electromagnetic spectrum data.
  • Fax. Disused technology for the transmission of information, the fax or telecopy consisted of the transmission by telephone signal of texts (and images), in the style of photocopiers and teletypewriters. It was displaced by faster telecommunications.
