Telecommunication basics

Communication is the process of conveying meaningful information between living beings. It is found everywhere in nature - signals travel inside plants and between cells, animals communicate intent and information between them and humans have used the exchange of information using increasingly complex symbols to survive since the dawn of man.

Telecommunication means communicating over distance, and it revolutionized our world. Paramount to the world economy, empowering to society though not without its troubles, enabling travel and making the world seem manageable, communicating large amounts of data fast between countries and continents has shaped the world into what it is today.

As the world becomes more and more digital, we will focus on how data is carried around the globe. The internet is full of information about how the world wide web works, and any aspiring network technician must know that it’s a network of powerful routers that connect to each other, each gathering data from its region, and each choosing what to send where. They are called backbone routers and are impressive machines that can cost up to millions of dollars. However, less information is available about how these routers are connected and here is where this series comes along.

As more articles will be written, the will be referenced here and hopefully something that resembles a telecommunications crash course will take shape in time. While there is no way such a primer will ever be able to replace a college course, it (again, hopefully) should be able to point the aspiring network engineer (or just interested party) in the right direction of study.
