Assembly language is essential when a new CPU is developed since it allows the development of higher-level language compilers for that CPU.  Assembly is also required for access to unique and low-level features of a CPU which is why portions of most [[operating system]]s must be written using assembly language.  Because assembly provides no abstractions, code written with it can run faster than equivalent code written in a high-level programming language. However, modern '''optimizing compilers''' are often better at generating efficient machine code than human-crafted assembly. Finally, writing assembly code is more tedious (and therefore more error-prone) than using a high-level language. The most notable
