Definition of ACCESS.bus
ACCESS.bus, or A.b, is a digital communication protocol primarily used to connect low-bandwidth devices, like keyboards, mice, and other peripherals, to a central system. It was developed in the 1990s by Philips Semiconductors and is based on the I²C (Inter-Integrated Circuit) serial bus system. ACCESS.bus allows multiple devices to be connected to a single bus, simplifying wiring and reducing overall system complexity.

Importance of ACCESS.bus
ACCESS.bus, or A.b, is a significant technology term because it refers to an innovative, low-cost, and low-power serial communication protocol that improves expandability and interoperability among a variety of devices.
Developed by Philips in the early 1990s, ACCESS.bus facilitates simplified connections and data transfers between multiple devices such as keyboards, mice, modems, and other peripherals.
It streamlines the management of numerous devices, reducing the need for multiple cables and managing multifarious connections.
Furthermore, the advanced capabilities of ACCESS.bus enable improved system configuration, diagnostics, and control, making it an essential milestone in the evolution of computer peripherals and communication technologies.
Explanation
ACCESS.bus, also known as A.b, is a communication protocol that facilitates the connection and interaction between low-bandwidth devices such as keyboards, mice, and other peripherals, and a computer system. The primary purpose of ACCESS.bus technology is to allow various peripheral devices to communicate with a computer system in an efficient, cost-effective, and organized manner. Its plug-and-play functionality enables users to connect or disconnect devices without having to restart the computer.
Developed by Philips and DEC in the early 1990s, ACCESS.bus aimed to streamline device management and minimize cable clutter by allowing multiple devices to be connected to a single port, thus reducing the need for individual connectors. The implementation of ACCESS.bus technology is advantageous for users who require flexibility and ease of use when interacting with their computer systems. The A.b protocol adapts the I²C (Inter-Integrated Circuit) serial bus system, ensuring efficient data transfer and reducing the possibility of data loss or miscommunication.
This makes it ideal for home and office environments, where several peripheral devices are present and are regularly connected or disconnected. Moreover, its inherent ability to support hot-swapping (connecting/disconnecting devices while the system is running) further enhances the user experience. Although ACCESS.bus technology has been largely replaced by newer connection interfaces such as USB and Bluetooth in recent years, it remains a notable innovation that paved the way for more advanced and versatile device management solutions.
Examples of ACCESS.bus
ACCESS.bus (Advanced Configuration, Control, and Energy Saving System bus) is an electronic bus protocol that facilitates two-way communication between simpler devices and microcontrollers. Here are three real-world examples of its application:
Peripheral Devices: ACCESS.bus technology can be found in peripheral devices like keyboards, mice, and other input devices as it allows for seamless communication with the host system. It simplifies device connectivity and management by standardizing the interface and protocols for digital communication, thus reducing complexity and support costs.
Industrial Controls: In industrial settings, ACCESS.bus can be utilized in devices and systems for data acquisition and control. It allows microcontrollers to communicate with plant machinery and sensors like temperature sensors or production line devices efficiently and effectively, making it easier to monitor and control the operation of these machines.
Energy Management Systems: ACCESS.bus has found its application in commercial energy management systems, where it helps coordinate and control energy-consuming devices like HVAC and lighting. It allows system administrators to monitor, control, and manage energy usage in real-time, ultimately leading to reduced operational costs and a more energy-efficient building.Overall, ACCESS.bus technology helps simplify digital communication and control in various applications, ranging from standard computer peripherals to industrial control systems and energy-efficient building systems.
ACCESS.bus FAQ
What is ACCESS.bus?
