A lot of the things you mentioned are abstracted away from most Software Engineers nowadays. Of course it's good to know how these things work, but for most SWE jobs it is not necessary to have a strong grasp of them. The world of software has grown tremendously, many companies need rather simple software that is built with high level frameworks and tools. On the other hand there are still people building compilers, game engines, routing algorithms or work on embedded systems where all the things you mentioned are much more important.
