Manchester Code Made Bits Behave
The Manchester code, developed in 1949, is recognized as a significant milestone in computing history. It was first implemented by G. E. (Tommy) Thomas during his master's thesis at the University of Manchester. This coding scheme has had a lasting impact on digital communication and data storage technologies.
- ▪The Manchester code was developed by G. E. (Tommy) Thomas in 1949.
- ▪It was the first implementation of a magnetic drum data storage prototype.
- ▪The coding scheme is now recognized as an IEEE Milestone.
