Which of the following would not be considered systems software?
- A.
An unzipper program
- B.
Communication software
- C.
A file management utility

D. A tax collection systemExplanation
A tax collection system is not considered systems software because it is not a program or utility that directly interacts with the computer's hardware or operating system. Systems software refers to software that manages and controls the computer system, such as operating systems, device drivers, and utility programs. In contrast, a tax collection system is an application software that is designed to handle specific tasks related to tax collection and management.Rate this question:

Word processing software could be said to belong to all of the following except ...
- A.
Productivity software
- B.
Utility
- C.

What is being described here... the ability of a computer to execute two or more programs at the same time using one CPU?
- A.
Multiprogramming
- B.
Multiprocessing
- C.
Multitasking
- D.
Multirunning
Correct Answer
A. MultiprogrammingExplanation
Multiprogramming refers to the ability of a computer to execute multiple programs at the same time using one CPU. This means that the CPU can switch between different programs, allowing them to run concurrently. Multiprogramming increases the efficiency and utilization of the CPU by keeping it busy with multiple tasks, even though only one program is being executed at any given moment.Rate this question:

What is being described here ... the ability of a computer to execute at the same time two or more related jobs?
- A.
Multiprogramming
- B.
Multiprocessing
- C.
Multitasking
- D.
Multirunning
Correct Answer
C. MultitaskingExplanation
Multitasking refers to the ability of a computer to execute two or more related jobs simultaneously. It allows the computer to switch between tasks quickly, giving the illusion of concurrent execution. This enables users to perform multiple tasks concurrently, such as running multiple applications or processes at the same time. Multitasking improves efficiency and productivity by maximizing the utilization of computer resources.Rate this question:

How many bytes make a KB?
- A.
1000
- B.
1000 X 1000
- C.
1024 X 1024
- D.
1024
Correct Answer
D. 1024Explanation
The correct answer is 1024. In computing, a kilobyte (KB) is typically defined as 1024 bytes, not 1000 bytes. This is because computers use a binary system, where numbers are based on powers of 2. Therefore, 1024 is the closest power of 2 to 1000, making it the standard unit for measuring memory and storage in computing.Rate this question:

In an RDBMS an attribute is analagous to ...
- A.
A file
- B.
A record
- C.
A field
- D.
A table
Correct Answer
C. A fieldExplanation
In an RDBMS, an attribute is analogous to a field. In a database table, each attribute represents a specific characteristic or property of the data being stored. Just like a field in a record, an attribute holds a single value for each instance or record in the table. It defines the type of data that can be stored in that particular column of the table. Therefore, the correct answer is "a field."Rate this question:

Which of the following is not a valid value for the field size property for a numeric field?
- A.
Decimal
- B.
Real
- C.
Integer
- D.
Byte
Correct Answer
B. RealExplanation
The field size property for a numeric field determines the range of values that can be stored in the field. In this question, the options "decimal," "integer," and "byte" are all valid values for the field size property as they represent different numeric data types with specific ranges. However, "real" is not a valid value for the field size property. "Real" is a term used to describe a floating-point data type, but it is not a valid option for the field size property.Rate this question:

The overall performance (speed) of a computer is based on the quality of several key components. Which does not belong?
- A.
Keyboard
- B.
RAM
- C.

The keyboard is not directly related to the overall performance (speed) of a computer. The other three components mentioned - RAM, processor, and memory - are all crucial in determining the speed and performance of a computer. The keyboard, although important for input, does not directly impact the overall speed and performance of a computer system.Rate this question:

An integrated software package ...
- A.
Can transfer data from one component to another easily
- B.
Costs less than individual components
- C.
Takes up less disk space than individual applications
- D.
A and B only
- E.
A, B and C
Correct Answer
E. A, B and CExplanation
An integrated software package can transfer data from one component to another easily, which allows for seamless communication and sharing of information between different parts of the software. Additionally, it often costs less than purchasing individual components separately, as it is bundled together as a package. Furthermore, since it combines multiple applications into one package, it takes up less disk space compared to installing and running multiple individual applications. Therefore, the correct answer is A, B, and C.Rate this question:

In order to set up a relational database we must create ________ between the tables in that database
Correct Answer
links
relationshipsExplanation
To set up a relational database, it is necessary to establish connections between the tables in the database. These connections are commonly referred to as links or relationships. By creating links or relationships between tables, we can define how the data in one table is related to the data in another table. This allows us to efficiently retrieve and manipulate data across multiple tables, ensuring the integrity and coherence of the database structure.Rate this question:
