Computers are an integral part to the operations of Babylon 5.
A computer is a general purpose device that can be programmed to carry out a set of arithmetic or logical operations automatically. Conventionally, a computer consists of a central processing unit (CPU), and some form of memory. The processing element carries out arithmetic and logic operations, and a sequencing and control unit can change the order of operations in response to stored information. Peripheral devices allow information to be retrieved from an external source, and the result of operations saved and retrieved.
Like most Shadow Technology, their ships require a living component to operate. This take the form of a specially prepared sentient being that once merged, acts as the ship's central processing unit. The only known weakness in this system is susceptibility to telepathic interference.
The technology the techno-mages use consists of bio-technological implants. The process of installing the implants and adjusting to them is excruciatingly painful. The presence of these implants means that techno-mages are effectively cyborgs. An unnamed techno-mage who had arrived on an unnamed planet in the distant past. This techno-mage built a huge computer core and transmitter and created a nano-virus that caused the population to kill each other.
