Computing Fundamentals Tutor Multiplex 05: Using a Bus

This video discusses the use of a bus as an alternative to the ever-increasing complexity of using multiplexers.

It is one of a series on multiplexers, digital circuits which allow the switching of binary signals to a number of destinations, using a binary number to select the destination. They are a useful component of many digital devices. In this video the use of a "Bus", a shared set of wires for data transfer between components is discussed, as an alternative to having multiple multiplexers for complex intercommunication.

This series in turn is part of a larger series that charts the creation of a simulated 4-Bit CPU, with clear explanations of what is happening at every step of the way. Following this Super-Series is a great way to gain a strong understanding of the hardware that underpins computers, and is a great learning experience for anyone interested in computing as a career or hobby.

Roadmap:

Understanding the basics of digital electronics is fundamental to the understanding of computer hardware, and this software allows you to explore that without the need for hardware, soldering irons and the such like.
