  • The pie-chart below shows some surprising results: most home networks have more than 5 computers (27,74%) or 4 computers (21,31%). The average is of 4,13 computers per home network. Summing up the results, it means that the 685 home networks participating in our study, have a total of at least 2832 computers (26+2*91+3*130+4*146+5*102+6*190).Up to 4 computers – 57,37%
  • If we combine these results with the previous question and the latest market share split between operating systems it means that, in each home network, there is at least 1 computer with Windows 7 installed and the others can be any mix of all operating systems, with Windows XP having the highest chances of being used. However, Linux, Windows Vista and Mac OS X are also likely to show up in the mix.
  • The results surprised us: apparently most people connect their homes to the Internet via a router they purchased personally (65% of home networks). Only 32% let their Internet Service Provide (ISP) decide for them and provide a router. We think this a wise choice and we hope more and more people will choose to purchase their own, newer & better devices. Unfortunately ISPs tend to use older and/or cheaper network hardware which are, often times, incompatible with newer technologies and operating systems.Other methods of connecting the home network to the Internet include having a LAN Cable connected to a computer which acts as a gateway for the others, or simply using a cable modems capable of also providing wireless signal.
  • The “Other" category of devices included mostly answers about mp3 players, with various flavors of iPods being mentioned very often. You might wonder why we did not include mp3 players as a separate category. The reason for this is due to the fact that, except a few models such as iPod Touch, mp3 players have a very simple interaction with the home network - it is mostly about transferring your music from one computer to the device. They are not used for anything else.
  • The good news from this study is that the percentage of home networks without any security solution installed is pretty small - only 3,07%. We looked at the individual responses and most home networks with no security solution installed mostly consist of computers running Linux and Mac OS X.
  • Wireless connection – very common,
