Some networks can be as big as the building that contains them while others can stretch across a continent. For example, a company that has one location for all its employees may have a wired network within a building. An IT professional can use a console server to connect with any other machine on the network within the building to solve issues. Some networks however can and are set up over the internet and span an entire country and even the world. Today’s multinational conglomerates have employees working in many different locations of the world. IT departments can connect with machines thousands of miles away if need be.
