Today’s traditional computer network is made up devices such as network switches, routers and controllers. A network switch connects devices to the network. A router sends and receives data to and from the network and connects a local network to the internet. A network controller optimizes performance according to input business objectives.
Modern computer networks, on the other hand, also include connections to everyday devices such as cameras, doorbells, audio/visual systems, thermostats, etc. These smart devices have the capability of connecting to the internet and make up what is commonly referred to as the Internet of Things (IoT).
Computer networks are the bedrock of IT communications, with the earliest examples being the room-sized computer networks from the 1960s. As technology advances and the list of IoT devices grows, computer networking and the need for professionals who can set up and maintain these networks will continue to be crucial. Only smooth-running and secure computer networks can ensure the seamless transfer of information we’ve come to expect of our connected devices.
