A Brief History of LAN LANs were first used by colleges and universities in the 1960s. These computer networks were used to catalog library collections, schedule classes, record student grades, and share equipment resources.

The cost to build and maintain these networks increases significantly as the range increases, of course....

How Much Space Do I Need on an Apple TV? If you only use a few apps, play a handful of games, and watch movies casually on the Apple TV, the lower-storage option is probably the best. If you want near-instant access to your music or images library, you may want to choose the larger capacity model, which should deliver better results if you have bandwidth constraints. If you expect to play lots of games and use all the other useful features, such as news and current affairs apps, it makes some sense to consider spending the extra money on a 64 GB model....
