Wet link

Wet Link is what Union Cyber techs call the link between hardware and bio tissue, or in other words the point where bio ends and tech starts (the connection between)

the term was  introduced in Pre Astro times on Terra from the term wetware.

Wetware is a term drawn from the computer-related idea of hardware or software, but applied to biological life forms. Here the prefix "wet" is a reference to the water found in living creatures. Wetware is used to describe the elements equivalent to hardware and software found in a person, namely the central nervous system (CNS) and the human mind. The term wetware finds use both in works of fiction and in scholarly publications.

The "hardware" component of wetware concerns the bioelectric and biochemical properties of the CNS, specifically the brain. If the sequence of impulses traveling across the various neurons are thought of symbolically as software, then the physical neurons would be the hardware. The amalgamated interaction of this software and hardware is manifested through continuously changing physical connections, and chemical and electrical influences that spread across the body. The process by which the mind and brain interact to produce the collection of experiences that we define as self-awareness is still seriously in question.
