Bluetooth

Bluetooth is a wireless technology standard for exchanging data over short distances (using short-wavelength UHF radio waves in the ISM band from 2.4 to 2.485GHz) from fixed and mobile devices, and building personal area networks (PANs).

Input/output base address

In the x86 architecture, an input/output base address is the first address of a range of consecutive read/write addresses that a device uses on the x86's IO bus.

Integrated circuit

An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, normally silicon.

Interrupt request (PC architecture)

In a computer, an interrupt request (or IRQ) is a hardware signal sent to the processor that temporarily stops a running program and allows a special program, an interrupt handler, to run instead.

Memory-mapped I/O

Memory-mapped I/O (MMIO) and port-mapped I/O (PMIO) (which is also called isolated I/O) are two complementary methods of performing input/output (I/O) between the central processing unit (CPU) and peripheral devices in a computer.

Serial port

In computing, a serial port is a serial communication interface through which information transfers in or out one bit at a time (in contrast to a parallel port).

Symbol rate

In digital communications, symbol rate, also known as baud rate and modulation rate, is the number of symbol changes, waveform changes, or signaling events, across the transmission medium per time unit using a digitally modulated signal or a line code.
