When most people arrive at their offices, the first thing they do is to work at their computers. They will open up their electronic mail, and see who has written to them. This is a priority task because the business communication between modern offices is mostly through the computer networks that connect them.

The most interesting development is that these emails can come from anywhere! They can arrive at the computer from colleagues who are just across the room in the same office. But they can also come from colleagues overseas, thousands of miles away. It is the network connecting computers that makes this worldwide communication possible.

The modern office has what is called a local area network, or LAN, which connects computers in the local office. It also connects them to printers that will produce documents on paper, which are useful references for meetings. These old style paper documents are also needed for office reference files. Some offices have scanners attached to the local network too. These act as “reverse” printers, because they convert(转换) documents into files that can then be used by the computer which sends them to other offices.

But to receive messages from overseas offices, a wide area network, or WAN, comes into play. This name explains that a much wider network than just LAN is used to send these messages from far away. This network consists of thousands of computers installed in different parts of the world, but all connected together.

The best example of a wide area network is the Internet. It turns out that the majority of office messages from overseas use part of the Internet, and this is one of the reasons why it keeps growing. New computers and connections are added every day, making each office in the world part of the growing international business community.

This is leading to “globalization”, which we hear more and more about each day. It means that offices can easily do their business with many other offices all over the world. So, modern computers and the networks connecting them are changing the way business is done.
