Fill in each of the blanks with one of the words given in the following list, making changes if necessary: A compiler, in computer science, is a computer program that translates source code into object code. Software engineers write source code using high-level programming languages that people can understand. Computers cannot directly execute source code, but need a compiler to translate these instructions into a low-level language called machine code. Compilers collect and reorganize (compile) all the instructions in a given set of source code to produce object code. Object code is often the same as or similar to a computer’s machine code. If the object code is the same as the machine language, the computer can run the program immediately after the compiler produces its translation. If the object code is not in machine language, other programs?such as assemblers, binders (联编程序), linkers, and loaders (加载程序)—finish the translation. Most computer languages use different versions of compilers for different types of computers or operating systems, so one language may have different compilers for personal computers (PC) and
