II. Choose from sentences A-G the one which fits each gap 1-5. There is one extra sentence you do not need to use. (1,0 p)

Every body has heard about the Internet, but do you know what an “internet” is? (0)___B____

In fact, intranets make use of the same software programs as the internet to connect computers and people. (1)__________.

If your intranet is working properly, it can link together huge amounts of information which is stored in different places in the company. ____________.

A company intranet can, of course, be used for unimportant information like office memos and canteen menus. (3)___________.

The intranet is a great idea, but the systemonly works if everyone on the intranet is willing to share their information with other people. (4))___________.

Another problem which often occurs is that top managers like to use the intranet to “communicate down” rather than to “communicate across”. (5)__________.

Unfortunately, many departments don’t want to share specialist knowlegde with others. It is a computer network that is private to a company, university, etc, but it is connected to and uses the same software as the Internet. In this way, people can get the information they need, regardless of where it comes from. Most employers prefer to communicate by telephone or in writing. But an intranet should provide important information which people need to make decisions about new products, costing and so on. This means that you do not have to buy a lot of additional programs to set up an intranet service. That is, they use the intranet to give orders, not to exchange information between themselves and others working in the same organization.
