The user is asking whether low-level programming languages emerged at the same time as computers. I'll explain that early computers used machine code and hardwiring, and low-level languages developed shortly afterward. Machine code existed as soon as stored-program architecture existed, with assembly following in the early 1950s.
Clarifying computer and low-level language development
The early computers from the 1930s/40s were either analog or rewired for programming, not using formal languages. Machine code existed as soon as stored-program computers appeared, around the late 1940s. Assembly languages developed in the 1950s, after machine code. Generally, high-level languages like Fortran came shortly thereafter.
