β | Computer programming involves writing instructions for a computer to follow, in a specific {{w|programming language}}, which is largely human readable and writable, at least to programmers who understand that language. However, for the computers to follow instructions, they need to be given {{w|machine code}} β the actual "language" that computers "speak" and one that ''can'' be written directly with the correct tools, but would be too tedious and error-prone for just about any practical modern project where alternatives exist, where anything more than a {{w|%22Hello,_World!%22_program|Hello World}} could be awkward to implement straight into machine-code. | + | Computer programming involves writing instructions for a computer to follow, in a specific {{w|programming language}}, which is largely human readable and writable, at least to programmers who understand that language.

Conversion from the more conveniently human-writable code into {{w|computer-executable files}} is performed by {{w|Assembly language#Assembler|assemblers}}, {{w|Interpreter_(computing)|interpreters}}, or {{w|compilers}}. | Conversion from the more conveniently human-writable code into {{w|computer-executable files}} is performed by {{w|Assembly language#Assembler|assemblers}}, {{w|Interpreter_(computing)|interpreters}}, or {{w|compilers}}. |
