Low level
A low-level programming language refers to machine code or what is called assembly language. This is the one closer to the hardware for small abstraction present between the latter and the machine language.
Low-level PL converts easily into machine code, something that a computer can directly process as is, so there is no need for a compiler or interpreter . The code runs on the processor itself ergo programs written with this run fast and do not consume that much in memory. However, because of its being easily understood by computer units, assembly language is more taxing for the programmers due to its technical data. It is very tedious and time-consuming to code in assembly. In comparison, high-level PLs can handle automatically most of its manually-defined functions.
