The availability of the appropriate compiler guarantees that a program developed on one type of machine can be compiled on a different type of machine.
true / false.

This is probably false. Take a language like C++, and even though some open source compilers will work for both Windows AND Linux, some functions or libraries may be available on Windows but not Linux and vice versa. Theoretically, if you're using the standard library and the compiler supports it, then yes, but in practice, the answer is usually no.

professionals can use many types of technology that can them. some examples are, computers (they research and can use for programs for data, they are also used for job applications, school work, and even to make new ideas), speedometers (can get data for unknown data), sometimes something as small as a pen (used for rough drafts, to insert data, and again job applications).

the correct answer is: a.)it is never appropriate to use acronyms and emoticons in business communication.
