Computer programmers develop the instructions and languages computers use to operate. They also resolve computer problems and logical tests within the system. The roles of programmers and programs have evolved with technical advancements in language and computing. The responsibilities and backgrounds of engineers vary depending on the company or agency.
Essentially, computer programs instruct the computer on how to function. These functions differ according to the information required. The time it takes to write a program ranges between a few hours for simple programs to years for more complex programs. Many programmers collaborate in a team in this process.
