What is data communications?

Offices and even homes have evolved into hi-tech spaces.

Think about an office space typically they contain computers, printers, scanners, copiers, alarm systems, CCTV and more depending on the type of business.

And today, even the humble home has the same hi-tech pieces of equipment including one or more smart TVs and video streaming devices.

What's even more incredible is that all these systems are fully capable to 'talk' to each other via the internet.

All this is possibly because of data communications.

Data communications refers to the transmission of digital data between two or more devices which can be computers, a computer network printers, smart TVs etc.

This telecommunications network allows various devices to exchange data.

The physical connection between networked computing devices is established using either cable media or wireless media.

Thanks to data communications, devices that are connected and communicating with each other allows us to enjoy many services that we take for granted in this digital age.

Data communications allows us to:

• Resource sharing such as printers and storage devices
• Exchange of information by means of e-Mails and FTP
• Information sharing by using Web or Internet
• Interaction with other users using dynamic web pages
• IP phones
• Video conferences
• Parallel computing
• Instant messaging
• Music and video streaming
• And so much more!

Data communication is an essential concept in the creation of computer networks.

Prior to the invention of networks, data had to be physically carried from one device to another.

The ability has driven the entire computer industry, including software innovations and the creation of the Internet as a medium for use by both professionals and the public.

Because of innovations in data communications technology:

• People can communicate and share information virtually instantaneously across the entire globe.
• Education and business concerns can take place no matter where the individual parties are located.

It is not an exaggeration to say that modern societies rely on data communications in order to function.
