問題 #127
Which generation of computing is known for the use of operating systems to allow for shared memory and resources?

答案：B

解題說明：
The third generation of computing is known for major advances in operating systems, especially the move toward multiprogramming, time-sharing concepts, and improved resource management. During this era, computers became powerful enough to support operating systems that could coordinate multiple programs and users more effectively, enabling shared use of memory, processing time, and peripheral devices. This meant that instead of a computer running only one program at a time with long idle periods, the operating system could schedule tasks, allocate memory, and manage input and output to keep the system busy and efficient. These developments matched the growth of integrated circuits, which improved speed and reliability and made more advanced system software practical. Third-generation systems also emphasized better user interaction through terminals and more standardized system environments. While later generations improved operating systems further, the third generation is widely credited in Information Technology history with establishing the operating system as a central system layer for managing shared resources. Therefore, the correct answer is the third generation.


問題 #128
A person is updating procedures for handling integer data within a database. Which value is an example of this data type?

答案：A

解題說明：
Integer data is a numeric data type used to store whole numbers without fractional or decimal parts. In Information Technology and database systems, integers are commonly used for counts, quantities, identifiers, and values that naturally occur as whole numbers. The value "the number of baseball games in a season" is a count and is expressed as a whole number, making it a clear example of integer data. By contrast, 3.14159 includes decimal places and is typically stored as floating-point or decimal data rather than integer. A single keystroke is character data because it represents a symbol such as A or 7, not a quantity. Whether a bank account does or does not have money in it is a two-state condition and is best represented as Boolean data, such as true or false. Using correct data types improves storage efficiency, supports accurate validation rules, and helps ensure correct query behavior. Therefore, the correct example of integer data is the number of baseball games in a season.


問題 #129
Which type of off-site storage is an empty shell that can be used for operations in the event of a natural disaster or terrorist attack?

答案：A

The type of off-site storage that serves as an empty shell for operations during a natural disaster or terrorist attack is a Cold site1. Unlike a Hot site, which is fully operational and ready for immediate use, a Cold site requires setup and provisioning before it can be utilized1. It provides a cost-effective solution for disaster recovery while minimizing ongoing expenses.
