True or False - ✔✔T
✔✔Practical optical processors will probably appear first as full-fledged computer
processors
True or False - ✔✔F
✔✔Traditional bus interfaces are too slow and power hungry to provide sufficient data
transfer capacity between many processors or between processors and primary
storage.
