Computing forms the brains of the Tactile Internet, and this chapter explores the various dimensions of computing, including quantum, molecular, digital, and analogue computing. It addresses the challenges and opportunities of privacy and secure computing in the Tactile Internet context. In addition, the chapter highlights fundamental computability considerations - rooted in Turing machines, Blum-Shub-Smale machines, and related theories - that impact which tasks can or cannot be solved in practice. The chapter also delves into reconfigurable computing systems, highlighting their importance in adapting to the dynamic requirements of Tactile Internet applications. It underscores the importance of trustworthy, energy-efficient, and low-latency computing systems in the Tactile Internet ecosystem. By examining these aspects, the chapter provides valuable insights into the computational foundations of the Tactile Internet.
