Copyright Goodheart-Willcox Co., Inc. 57 Chapter 2 Operating Systems Network Discovery Network Discovery was introduced with Windows Vista and has continued to be supported by Windows 7, Windows 8, and Windows 10. It makes setting up and con- fi guring a network easy as it automatically detects and confi gures a network and sets up a share and Internet connection. It also allows fi les to be shared much easier in a peer-to-peer network, while still providing security from the Internet. Th e main exception arises if there is a router or gateway being used that is not compatible with the automatic networking features. Figure 2-18 shows the Advanced sharing settings menu, which is accessed from the Network and Sharing Center. Notice the Network discovery option in the File and printer sharing sections of the menu. Th ese options let you enable and disable the respective features. Windows Shadow Copy and Previous Versions Th e Windows Shadow Copy feature automatically makes a copy of fi les that have changed and been saved. Th is feature allows a user to open an earlier version of a fi le using the Previous Versions feature. To restore a fi le using the Previous Versions feature, right-click the folder that held that fi le or the current version of that fi le and select Properties from the shortcut menu. Next, select the Previous Versions tab. Previous versions of the fi le will be listed. Select the desired fi le and then click Restore. Windows Shadow Copy was fi rst introduced in Windows Server 2003. It is available in Windows 7, Windows 8, and Windows 10, although the features vary slightly between the various versions. Windows ReadyBoost Many software programs require a great deal of RAM to operate effi ciently. Otherwise, the program responds slowly, may not work at all, or the system will seem to freeze up. Operating systems typically use the hard drive to store limited amounts of program information when RAM is full. For example, a computer with 1 GB of RAM may use 500 kB of memory, referred to as a page fi le, to store information temporarily. Th is keeps the program working reasonably well when the RAM is full. However, compared to RAM, the hard drive is notoriously slow when accessing and manipulating data.
