11、d out, a computer must execute a program, that is, the computer reads the program, and then follow the steps encoded in the program in a precise order until completion. a program can be executed many different times, with each execution yielding a potentially different result depending upon the opti

12、ons and data that the user gives the computer. 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 game-playing. an operating system is a program that manages th

13、e computer 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, os2, and unix. 2 2 program development software designers create new p

14、rograms 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

15、, 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 codea format that the op

16、erating system will recognize as a proper program and be able to execute. three types of applications programs translate from source code to object code: compilers, interpreters, and assemblers. the three operate differently and on different types of programming languages, but they serve the same pu

17、rpose of translating from a programming language into machine language. a compiler translates text files written in a high-level programming language-such as fortran, c, or pascalfrom the source code to the object code all at once. this differs from the approach taken by interpreted languages such a

18、s 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 compiled. change

19、s can also be made to the program fairly quickly without having to wait for it to be compiled 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, com

20、piled languages are compiled only once and thus can be executed by the computer much more quickly than interpreted languages. for this reason, compiled languages are more common and are almost always used in professional and scientific applications. another type of translator is the assembler, which

21、 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 high- level languages. in assembly language, a single statement can usually be translated into a single inst

22、ruction 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 computers function. programs are often written as a set of smaller pieces, with each piece representing som

23、e aspect of the overall application program. after each piece has been compiled separately, a program called a linker combines 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 probl

24、ems called bugs. debugging programs usually detect an event in the executing program and point the programmer back to the origin of the event in the program code. recent programming systems, such as java, use a combination of approaches to create and execute programs. a compiler takes a java source

25、program and translates it into an intermediate form. such intermediate programs are then transferred over the internet into computers where an interpreter program then executes the intermediate form as an application program. 3 3 program elements most programs are built from just a few kinds of step

26、s that are repeated many times in different contexts and in different combinations throughout the program. the most common step performs some computation, and then proceeds to the next step in the program, in the order specified by the programmer. programs often need to repeat a short series of step

27、s many times, for instance in looking through a list of game scores and finding the highest score. such repetitive sequences of code are called loops. one of the capabilities that makes computer so useful is their ability to make conditional decisions and perform different instructions based on the

28、values of data being processed. if-then-else statements implement this function by testing some piece of data and then selecting one of two sequences of instructions on the basis of the result. one of the instructions in these alternatives may be a goto statement that directs the computer to select

29、its next instruction from a different part of the program. for example, a program might compare two numbers and branch to a different part of the program depending on the result of the comparison: if x is greater than y then goto instruction # 10 else continue program often use a specific sequence o

30、f steps more than once. such a sequence of steps can be grouped together into a subroutine, which can then be called, or accessed, as needed in different parts of the main program. each time a subroutine is called, the computer remembers where it was in the program when the call was made, so that it

31、 can return there upon completion of the subroutine, allowing a very general piece of code to be written once and used in multiple ways. most programs use several varieties of subroutines. the most common of these are functions, procedures, library routines, system routines, and device drivers. func

32、tions are short subroutines that compute some value, such as computations of angles, which the computer cannot compute with a single basic instruction. procedures perform a more complex function, such as sorting a set of names. library routines are subroutines that are written for use by many differ

33、ent programs. system routines are similar to library routines but are actually found in the operating system. they provide some service for the application programs, such as printing a line of text. device drivers are system routines that are added to an operating system to allow the computer to com

34、municate with a new device, such as a scanner, modem, or printer. device drivers often have features that can be executed directly as applications programs. this allows the user to directly control the device, which is useful if, for instance, a color printer needs to be realigned to attain the best

35、 printing quality after changing an ink cartridge. 4 4 program function modern computers usually store programs on some form of magnetic storage media that can be accessed randomly by the computer, such as the hard drive disk permanently located in the computer, or a portable floppy disk. additional

36、 information on such disks, called directories, indicate the names of the various program begins on the disk media. when a user directs the computer to execute a particular application program, the operating system looks through these directories, locates the program, and reads a copy into ram. the

37、operating system then directs the cpu to start executing the instructions at the beginning of the program. instructions at the beginning of the program prepare the computer to process information by locating free memory locations in ram to hold working data, retrieving copies of the standard options

38、 and defaults the user has indicated from a disk, and drawing initial displays on the monitor. the application program requests copy of any information the user enters by making a call to a system routine. the operating system converts any data so entered into a standard internal form. the applicati

39、on then uses this information to decide what to do next-for example, perform some desired processing function such as reformatting a page of text, or obtain some additional information from another file on a disk. in either case, calls to other system routines are used to actually carry out the disp

40、lay of the results or the accessing of the file from the disk. when the application reaches completion or is prompted to quit, it makes further system calls to make sure that all data that needs to be saved has been written back to disk. it then makes a final system call to the operating system indi

41、cating that it is finished. the operating system then frees up the ram and any device that the application was using and awaits a command from the user to start another program. 5 history people have been storing sequences of instructions in the form of a program for several centuries. music boxes o

42、f the 18th century and player pianos of the late 19th and early 20th centuries played musical programs stored as series if metal pins, or holes in paper, with each line representing when a note was to be played, and the pin or hole indicating what note was to be played at that time. more elaborate c

43、ontrol of physical devices became common in the early 1800s with french inventor joseph marie jacquards invention of the punch-card controlled weaving loom. in the process of weaving a particular pattern, various parts of the loom had to be mechanically positioned. to automate this process, jacquard

44、 used a single paper card to represent each positioning of the loom, with hole in the card to indicate which loom actions should be done. an entire tapestry could be encoded onto a deck of such cards, with the same deck yielding the same tapestry design each time it was used. programs of over 24,000

45、 card were developed and used. the worlds first programmable machine was designed-although never fully built- by the english mathematician and inventor, charles babbage. this machine, called the analytical engine, used punch cards similar to those used in the jacquard loom to select the specific ari

47、r completed because the technology required to build it did not exist at the time. the first card deck programs for the analytical engine were developed by british mathematician countess augusta ada lovelace, daughter of the poet lord byron. for this reason she is recognized as the worlds first prog

48、rammer. the modern concept of an internally stored computer program was first proposed by hungarian-american mathematician john von neumann in 1945. von neumanns idea was to use the computers memory to store the program as well as the data. in this way, programs can be viewed as data and can be proc

49、essed like data by other programs. this idea greatly simplifies the role of program storage and execution in computers. 6 the future the field of computer science has grown rapidly since the 1950s due to the increase in their use. computer programs have undergone many changes during this time in res

50、ponse to user need and advances in technology. newer ideas in computing such as parallel computing, distributed computing, and artificial intelligence, have radically altered the traditional concepts that once determined program form and function. computer scientists working in the field of parallel

51、 computing, in which multiple cpus cooperate on the same problem at the same time, have introduced a number of new program models. in parallel computing parts of a problem are worked on simultaneously by different processors, and this speeds up the solution of the problem. many challenges face scien

55、igence has led to several other new styles of programming. logic programs, for example, do not consist of individual instructions for the computer to follow blindly, but instead consist of sets of rules: if x happens then do y. a special program called an inference engine uses these rules to “reason
