Many people who work with computers and networks do not read the documentation that comes with the products they use. B. To cut costs most hardware and software manufacturers have greatly reduced the amount of printed documentation they include with products. C. To properly administer and troubleshoot a network you must have information about the products you are using. 1. In many cases you must turn to resources other than the product manufacturer to get information. 2. Many other sources of information are now available to the network administrator. 2.

Even if you do not need to read the manual to install or configure the product you should always keep all the documentation. 1. Although you may be very familiar with the devices or software products you use you might still need the documentation some day. a. Example suppose you need to install additional memory in all the computers on an existing network. 1 You might not know what type of memory modules you need what combinations of modules the computers support or how much memory they can use. 2 Suppose that the company that manufactured those computers no longer makes or supports the model you are using. a If you have kept the documentation you can probably find the information you need. b If you do not have the documentation you will have to determine by trial and error what memory configurations the computers can use which could waste a lot of time and money.
