"High-level language" refers to the higher level of abstraction from [[machine language]]. Rather than dealing with registers, memory addresses, and call stacks, high-level languages deal with variables, arrays, [[object (computer science)|object]]s, complex arithmetic or booleanBoolean expressions, subroutines and functions, loops, [[Thread (computer science)|thread]]s, locks, and other abstract computer science concepts, with a focus on [[usability]] over optimal program efficiency. Unlike low-level [[assembly language]]s, high-level languages have few, if any, language elements that translate directly into a machine's native [[opcode]]s. Other features, such as string handling routines, object-oriented language features, and file input/output, may also be present. One thing to note about high-level programming languages is that these languages allow the programmer to be detached and separated from the machine. That is, unlike low-level languages like assembly or machine language, high-level programming can amplify the programmer's instructions and trigger a lot of data movements in the background without their knowledge. The responsibility and power of executing instructions have been handed over to the machine from the programmer.
