Connectivity - RS232The beginning of the design of RS-232 is used to connect the modem for transmission purposes, and therefore its pin significance is usually and modem transmission. RS-232 devices can be divided into the data terminal device (DTE) and data communication devices (DCE) categories, this sub-category defines the different lines used to send and accept the signal. In general, computers and terminal devices DTE connector, modem and printer DCE link.

Connectivity - USB

USB was originally advocated by Intel and Microsoft launched its biggest feature is support hot-swappable and Plug and Play. When the device is inserted into the host listed this device and load the required drivers, so convenient to use than the PCI and ISA bus.USB faster than the parallel port and serial port and other traditional computer with a standard bus is much faster. USB 1.1 maximum bandwidth for 12Mbps USB 2.0 maximum bandwidth to 480 Mbps. USB 3.0 5Gbps.

Bluetooth is a wireless transmission technology that allows desktop and notebook computers, mobile phones, PDAs, printers, scanners, digital cameras and even home appliances, short-range wireless link.
