In fact, you can get away with paying a minimal amount for extra software and hardware if these accessories are for children. The convenience of having information at our immediate access is phenomenal - so much so that thousands of programmers have jumped on the opportunity to build unique applications specific to these small machines. As a result, you can find tons of games, databases, GPA systems, weather reporting programs, and even small encyclopedias on these things - each accessible not at the click of a mouse - but at a few presses of a free thumb. The network card is similar to the old modems we used in the past to connect to the Internet, however in a home network, it's used to communicate with every computer that's connected to it.
