  Concurrent with advancements in molecular communication (MC), bacterial
communication is emerging as a key area of interest. Given the frequent use of
bacteria in various MC models, it is essential to have a thorough grasp of
their intrinsic communication, signaling, and engineering techniques. Although
it is crucial to have a strong understanding of the communication background,
the inherent biological variability of bacteria may introduce complexity. Thus,
an in-depth understanding of bacteria and their communication is a must for
improving and extending the models in which they are utilized. Furthermore, the
emerging and evolving domain of bacterial computing provides an exciting
opportunity for advancing applications in areas such as environmental
monitoring and biological computing networks. By integrating the communication
and sensing capabilities, bacterial computing offers a promising framework for
enhancing the adaptability and responsiveness of bacteria. This paper provides
a comprehensive review of bacterial communication and computing, illustrating
their application and the link with the concept of the Internet of Everything
(IoE). Through the analysis of these biological systems, we reach a deeper
insight on how the small-scale interactions may contribute to the major concept
of universal interconnectedness; thus, we make the knowledge to flow and
communication stronger between different fields. The discussion include the
identification of the different bacterial mechanisms that could revolutionize
the traditional communication systems. Thus, this paper offers valuable
insights into previously unaddressed aspects of bacterial behavior, suggesting
novel avenues for future research and aiming to advance understanding and
application of bacterial sensing, communication and computing in MC models.
