There are numerous interfaces used on personal computers. Obviously, processor system buses as well as PCI Express are the most popular interfaces inside personal computers – they are present in almost all PCs sold today. But what about the external interfaces? According to a survey by a research company, Bluetooth and Universal Serial Bus are the most popular external interfaces that are utilized nowadays. In fact, USB is the most popular interface in general.

USB is the most popular and most used interface among users on both home and business PCs, while Bluetooth is proving highly popular on cell phones, reports In-Stat. According to an In-Stat survey of U.S. consumers, both interfaces are well known for multiple uses at home and at work.

“For home use, USB flash drives were the most popular USB application, followed by printers and digital still cameras. For Bluetooth, 34% of respondents use the interface to connect their mobile phones to home PCs. Mouse/keyboards and PDA/handheld PCs were commonly connected via Bluetooth as well,” said Brian O’Rourke, In-Stat analyst.

According to the report from In-Stat, USB is the most-used digital interface in home and work PCs, followed by IEEE 1394 (FireWire), Bluetooth, DVI and HDMI.

Even though Bluetooth is, generally speaking, a proprietary standard, well over half of respondents own a mobile phone with Bluetooth technology; with nearly 60% of them using it to connect a Bluetooth headset.

According to In-Stat, over 25% of respondents with HDMI ports on their PC said they used HDMI to connect their PC to their digital television (DTV).
