physical

physical definition - telecom

Something that exists in the reality of the material world, rather than in logic, as an idea or notion. Something physical is tangible and can be seen and touched. A physical circuit, for example, might consist of metal, glass, or plastic.
Associated with the sciences such as chemistry and physics that deal with nonliving things such as energy and matter, rather than the sciences such as biology and physiology that deal with living organisms. So, a radio circuit is physical, even though it is not tangible.
