the first unix operating system was originally written in which language?
assembly
the origin of c is closely tied to the development of the unix operating system, originally implemented in assembly language on a pdp-7 by dennis ritchie and ken thompson, incorporating several ideas from colleagues. eventually, they decided to port the operating system to a pdp-11. the original pdp-11 version of unix was developed in assembly language. thompson needed a programming language to make utilities. at first, he tried to make a fortran compiler, but soon gave up the idea and made a new language, b, thompson's simplified version of bcpl. however, few utilities were written in b because b was too slow, and b could not take advantage of pdp-11 features such as byte addressability.
