Connectivity - RS232
The 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
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.
