UNIBUS Meaning and
Definition
-
The term "UNIBUS" refers to a computer bus architecture that was developed by Digital Equipment Corporation (DEC) in the 1960s and widely used in their PDP-11 series of computers. UNIBUS stands for "universal bus" as it was designed to be a versatile and general-purpose bus system for interconnecting various hardware components within the computer system.
The UNIBUS can be defined as a bidirectional parallel bus that enables the transfer of data, control signals, and addresses between different devices or subsystems of a computer. It consists of a set of electrical lines or wires that transmit binary information synchronized by a clock signal.
The UNIBUS architecture follows a shared bus concept where multiple devices can be connected to the same bus and communicate with each other. The bus supports both input and output operations, allowing devices to send or receive data.
One of the key features of the UNIBUS is its simplicity and ease of use. It uses a single wire for address decoding and allows various devices to be added or removed dynamically without the need for extensive reconfiguration.
The UNIBUS architecture played a significant role in the popularity and success of the PDP-11 series, as it allowed for easy expansion and customization of the systems. However, with the advancement of technology, the UNIBUS was eventually replaced by more advanced and faster bus architectures in later computer systems.
