For the instructions to be carried out, a puter must execute a program, that is, the puter reads the program, and then follow the steps encoded in the program in a precise order until pletion. A program can be executed many different times, with each execution yielding a potentially different result depending upon the options and data that the user gives the puter. Programs fall into two major classes: application programs and operating systems. An application program is one that carries out some function directly for a user, such as word processing or gameplaying. An operating system is a program that manages the puter and the various resources and devices connected to it, such as RAM, hard drives, monitors, keyboards, printers, and modems, so that they may be used by other programs. Examples of operating systems are DOS, Windows 95, OS\2, and UNIX. 2 Program Development Software designers create new programs by using special applications programs, often called utility programs or development programs. A programmer uses another type of program called a text editor to write the new program in a special notation called a programming language. With the text editor, the programmer creates a text file, which is an ordered list of instructions, also called the program source file. The individual instructions that make up the program source file are called source code. At this point, a special applications program translates the source code into machine language, or object code—a format that the operating system will recognize as a proper program and be able to execute. Three types of applications programs translate from source code to object code: 2 pilers, interpreters, and assemblers. The three operate differently and on different types of programming languages, but they serve the same purpose of translating from a programming language into machine language. A piler translates text files written in a highlevel programming languagesuch as FORTRAN, C, or Pascal—from the source code to the object code all at once. This differs from the approach taken by interpreted languages such as BASIC, APL and LISP, in which a program is translated into object code statement by statement as each instruction is executed. The advantage to interpreted languages is that they can begin executing the program immediately instead of having to wait for all of the source code to be piled. Changes can also be made to the program fairly quickly without having to wait for it to be piled again. The disadvantage of interpreted languages is that they are slow to execute, since the entire program must be translated one instruction at a time, each time the program is run. On the other hand, piled languages are piled only once and thus can be executed by the puter much more quickly than interpreted languages. For this reason, piled languages are more mon and are almost always used in professional and scientific applications. Another type of translator is the assembler, which is used for programs or parts of programs written in assembly language. Assembly language is another programming language, but it is much more similar to machine language than other types of highlevel languages. In assembly language, a single statement can usually be translated into a single instruction of machine language. Today, assembly language is rarely used to write an entire program, but is instead most often used when the programmer needs to directly control some aspect of the puter’s function. Programs are often written as a set of smaller pieces, with each piece representing some aspect of the overall application program. After each piece has been piled separately, a program called a linker bines all of the translated pieces into a single executable program. Programs seldom work correctly the first time, so a program called a debugger is often used to help find problems called bugs. Debugg
