An applet ________
-
is an interpreted program that runs on the client
-
tracks the number of visitors to a Website
-
Is a compiled program that usually runs on the client
-
Collects data from visitors to a Website
-
None of these
Correct Answer
A. is an interpreted program that runs on the clientExplanation
An applet is an interpreted program that runs on the client. This means that it is a program written in a high-level language, such as Java, that is executed by the client's web browser. It is different from a compiled program, which is converted into machine code before execution. Applets are commonly used to add interactive features to websites and can perform various tasks, such as tracking the number of visitors or collecting data from visitors. Therefore, the correct answer is that an applet is an interpreted program that runs on the client.Rate this question:

Data are ________ in client/server computing.
-
Never sent to the client machine
-
Sent in very large sections to save processing time
-
Sent only upon the client's request
-
Sent in complete copies for the client to filter and sort
-
None of these
Correct Answer
A. Sent only upon the client's requestExplanation
In client/server computing, data are sent only upon the client's request. This means that the server does not automatically send data to the client machine without the client explicitly asking for it. This approach helps to optimize the use of network resources and processing time by only sending the necessary data when it is needed by the client.Rate this question:

Choose the correct way to indicate that a line in a C++ program is a comment line, that is, a line the will not be executed as an instruction ________ .
-
Begin the line with a # sign
-
Begin the line with double slashes (/ /)
-
Begin and end the line with double hyphens (- _ -)
-
Indent the line
-
None Of these
Correct Answer
A. Begin the line with double slashes (/ /)Explanation
In C++, the correct way to indicate a comment line is by beginning the line with double slashes (//). This syntax tells the compiler to ignore everything on that line, treating it as a comment rather than an executable instruction. The other options listed (beginning the line with a # sign, beginning and ending the line with double hyphens, and indenting the line) are not valid ways to create comment lines in C++. Therefore, the correct answer is to begin the line with double slashes (/ /).Rate this question:

The ________ converts digital signals to analog signals for the purpose of transmitting data over telephone lines.
-
Router
-
Modem
-
Bridge
-
Mux
-

The degree of detail that should be incorporated into a database depends on what?
-
Data integrity
-
The type of database
-
The user's perspective
-
The business practices and policies
-
None of these
Correct Answer
A. The type of databaseExplanation
The degree of detail that should be incorporated into a database depends on the type of database. Different types of databases have different requirements and purposes, so the level of detail needed will vary. For example, a financial database may require a high level of detail to accurately track transactions and balances, while a customer database may only need basic information such as names and contact details. Therefore, the type of database is a crucial factor in determining the appropriate level of detail to be included.Rate this question:

With the object-oriented (OO) approach, an object encapsulates, or ________ a programmer.
-
Carries out, the details of an object for
-
Hides, the details of an object from
-
Reveals, the details of an object to
-
Extends, the details of an object beyond
-
None of these
Correct Answer
A. Hides, the details of an object fromExplanation
The correct answer is "hides, the details of an object from". In object-oriented programming, encapsulation is a fundamental principle where the internal details of an object are hidden from the outside world. This allows the object to maintain its integrity and ensures that only the necessary information is accessible to other parts of the program. By hiding the details, the object provides a clean interface for other programmers to interact with, promoting modularity and code reusability.Rate this question:

-
(d) tests if the data in two or more associated fields is logical tests if the data in two or more associated fields is logical
-
None of these
Correct Answer
A. Determines whether a number is within a specified limitExplanation
A range check is a type of validation that determines whether a number is within a specified limit. It is used to ensure that the entered data falls within an acceptable range or boundary. This helps to prevent errors or inconsistencies in the data. For example, if a field is supposed to accept values between 1 and 100, a range check would verify if the entered number is within this range. If it is not, an error message or prompt can be displayed to the user, indicating that the input is invalid.Rate this question:

Which error detection method uses one's complement arithmetic?
-
Simply parity check
-
Checksum
-
Two-dimensional parity check
-
CRC
-
None
Correct Answer
A. ChecksumExplanation
Checksum is an error detection method that uses one's complement arithmetic. In checksum, the data is divided into equal-sized blocks and a sum is calculated for each block. This sum is then added to the data and sent along with it. At the receiving end, the sum is recalculated and compared with the received sum. If they match, it is assumed that the data is error-free. One's complement arithmetic is used in checksum to ensure that any errors in the data are detected.Rate this question:
