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 bit-rate of available or consumed information capacity expressed typically in metric multiples of bits per second.

Bus (computing)

In computer architecture, a bus (related to the Latin "omnibus", meaning "for all") is a communication system that transfers data between components inside a computer, or between computers.

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.

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 between the CPU and peripheral devices in a computer.

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.
