During the past 20 years, the planet has gradually been covered by computer networks of various kinds. Understanding the basics of how these networks work helps us learn how to better use them and also increases our awareness of the changing world around us. This installment of our series on "How Computer Networks Work" examines devices - hardware systems that connect to the network and communicate with each other.
Assembling the physical pieces of a computer network by itself is insufficient to make it function – connected devices also require a method of communication. These communication languages are called network protocols.
There's no shortage of people offering advice to help teach others about computer networks. For some reason, though, certain facts about networking tend to be misunderstood, generating confusion and bad assumptions. This article describes some of these more commonly-held misconceptions.
