29. client/server architecture
An arrangement used on local networks. It splits the processing of an application between a “front-end” client and a “back-end” server. The client component is a complete, stand-alone personal computer (not a terminal) and it offers the user its full range of power and features for running applications. The server component can be a personal computer, minicomputer, or mainframe that provides data management, information sharing between clients, and sophisticated network administration and security features. The client portion of the application is typically optimized for user interaction. The server portion provides the centralized, multi-user functionality.
30. OOP (object-oriented programming)
A programming paradigm in which a program is viewed as a collection of discrete objects that are self-contained collections of data structures and routines that interact with other objects.
31. algorithm
A finite sequence of steps for solving a logical or mathematical problem.
32. protocol
A set of rules or standards designed to enable computers to connect with one another and to exchange information with as little error as possible.
33. email
The exchange of text messages and computer files over a communications network, such as a local area network or the Internet, usually between computers or terminals.
34. process
It is the vital step between receiving data and producing results. It’s the manipulation of data within a computer system.
35. thread
In email and Internet newsgroups, a series of messages and replies related to a specific topic.
36. Unix system
A multi-user, multitasking operating system used on minicomputers. It is more portable than other operating systems, because it is written in the C language.
37. structured programming
It makes programs more clean flow, more clear design. Let programs have a degree of modularity and hierarchical structure.
38. ATM

40. DDL
Data Definition Language.
It’s a language that defines all attributes and properties of a database, especially record layouts, field definitions, key fields, file locations, and storage strategy.


1. -system database is used to store the system data, such as the structure of tables.
-application database is used to store the data of user’s application, such as names, numbers, addresses and so on.

2. –programmer only coding and debug programs according the specification.
-computer analyst’s duty is more complicated. They design the project and make the specification.
-software engineer coding and debug programs too, but they make the specification sometimes.

3. -bit
One byte is 8 bits.
4. -C compile to the machine code, and than execute.
-Basic is a kind of executive language. The program compiles and run at the same time.

5. -C Process-Oriented language
-C++ Object-oriented language

6. -system programming is related to the system equipment.
-application programming is just related to user’s needs.

7. -logical means more general, physical.
-grammatical means more specific and detail.
The difference between them is that “logical” is related to system or algorithm design and “grammatical” is related to coding.

8. -assembly language can direct programmer interaction with system hardware, so it increases execution speed.
-other language must be used on some operate systems which are based on hardware.
9.–-batch processing The practice of acquiring programs and data sets from users, running them one or a few at a time, and then providing the results to the users.
-interactive processing involves the more or less continuous participation of the user. Such a command/response mode is characteristic of microcomputers.


1. Which is difficult to find out, logical error or grammatical error?
Logical error of course. When you compile the program, the compiler will tell you the grammatical errors: how many errors and where they are. But it will not tell you logical errors. From syntax, the program is perfect, but it can’t give out the right result. That is logical error. It’s difficult to find out where logical error is and how it occurs.
2. Tell me three types of database.
Relational database , Network database, Hierarchical database.
Relational database stores information in tables and conducts searches by utilizing data in specified columns of one table to find additional data in another table. In a relational database, the rows of a table represent records (collections of data about separate items) and the columns represent fields.
3. Which type of database is related to table?
Relational database.
4. How to implement a program?
5. How to design a database?
Analyze the entry-relation of objects, then design the table for every entry and the relation table for every relation, and finally connect these tables.
6. Why it is difficult to modify other programmer’s program? How to make it easy?
Because you have to understand the idea of other programmers, it takes a long time. Meanwhile, the coding styles are various. To make it easier, first of all, every programmer should code in a readable style using necessary spaces, comments and so on. Besides that, a detailed document should be provided with the codes and be updated whenever the codes are changed. Secondly, we should improve our coding skills. After coding, we should test all the codes and avoid all the errors.
7. Please illustrate the formal steps of developing a user needed software system.
8. How to compile a program? How to make the compiling faster?
9. How to write a homepage?
First, you must edit the documents what the homepage needs. Then, use FTP tools put the documents on to the web server.
10. How to debug the program?
In the developing tools, insert a breakpoint in the resource code, and then run the program. When it runs to the breakpoint, it steps, then I can use watch window to see the values of variables. If the values are correct, I insert the breakpoint forwardly.
11. How to test the program? (in a network)
Run the program on a server, and make some request input in the client, and wait to see if the right response will arrive.
