Asynchronous communication

In telecommunications, asynchronous communication is transmission of data, generally without the use of an external clock signal, where data can be transmitted intermittently rather than in a steady stream.

Bandwidth (computing)

In computing, bandwidth is the maximum rate of data transfer across a given path.

Burst mode (computing)

Burst mode (alternatively burst-mode) is a generic electronics term referring to any situation in which a device is transmitting data repeatedly without going through all the steps required to transmit each piece of data in a separate transaction.

Bus (computing)

In computer architecture, a bus (a contraction of the Latin omnibus) is a communication system that transfers data between components inside a computer, or between computers.

Bus mastering

In computing, bus mastering is a feature supported by many bus architectures that enables a device connected to the bus to initiate direct memory access (DMA) transactions.

Byte addressing

Byte addressing refers to hardware architectures which support accessing individual bytes of data rather than only larger units called words, which would be word-addressable.

In telecommunications, a handshake is an automated process of negotiation between two communicating participants (example "Alice and Bob") through the exchange of information that establishes the protocols of a communication link at the start of the communication, before full communication begins.

Interrupt priority level

The interrupt priority level (IPL) is a part of the current system interrupt state, which indicates the interrupt requests that will currently be accepted.

Master/slave (technology)

Master/slave or primary/replica is a model of communication where one device or process has unidirectional control over one or more other devices.

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.

Programmed Data Processor

Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor, is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.

Vectored Interrupt

In computer science, a vectored interrupt is a processing technique in which the interrupting device directs the processor to the appropriate interrupt service routine.

1801 series CPU

The 1801 series CPUs were a family of 16-bit Soviet microprocessors based on the indigenous Elektronika NC microarchitecture cores, but binary compatible with DEC's PDP-11 machines.
