Leaving in these modern times means that you need to constantly build up your knowledge, and make sure that you truly understand the world around you. Computers are everywhere, and they became very important part of everyday life of many people all around the globe. You have heard about computer networking so many times before for sure, but have you ever really wondered what computer networking actually is? Here is a little explanation that will help you to understand it a little bit better.
Computer networking actually means that two or more computers are linked in order to share certain data. Those networks are built with mixture of computer software and computer hardware. Networks are categorized in a few entirely different ways. One of the main approaches in making a difference between networks is according to network’s geographic area. There are two main types of computer networks such as LAN – Local area networks: Those networks are usually networks created in one house or apartment, some small office, or school or college. On the other hand, there are WAN – wide area networks: those computer networks reach across states, cities or the whole globe. When you think a bit more, you can come to the conclusion that Internet actually is largest public wide area network (WAN), in the entire world.
The other difference between computer networks is their design. Once again, there are two main types of networks which are completely different because of their design. First one is client/server network – server computers which are storing files, web pages, emails and some other applications; the other one is peer to peer: in this case, all computers supporting all the same functions. Peer to peer networks are common in homes and client/server networks are common in businesses.
Some networks must be properly maintained by engineers, and on the other hand there are home networks, and those networks belong to people who often have not even a little technical background. Those networks can be easily setup and they are used for files sharing. Home networks today are a lot better then they used to be, because modern technologies are constantly improving. Back in times, people could just set their networks in order to share certain documents. Today, people can network so many different things such as smartphones, digital video recorders, consoles, etc. Business networks are a little bit different that home networks, and the main difference is the fact that home networks contain one LAN, and on the other hand, business networks have several LANs.
The thing is, whole computer networking field became more popular and start to increase since WWW – Word Wide Web was created. That happened during the 1990s.
