質問 # 47
What is one of the factors that determines the choice of an operating system?
正解：A
解説：
One major factor that determines the choice of an operating system is the device type. Operating systems are designed for specific categories of hardware and usage environments, such as desktop computers, servers, mobile phones, tablets, embedded devices, and network appliances. In Information Technology fundamentals, selecting an operating system begins with identifying the platform requirements, including processor architecture, memory limits, battery needs, and how the device will be used. For example, iOS and Android are designed for mobile devices, Windows and macOS are designed for desktops and laptops, and server operating systems are tuned for reliability, remote administration, and multi-user workloads. While driver compatibility is also an important consideration, many curricula treat it as a sub-factor related to hardware support within a chosen device category. Number of devices relates more to licensing and deployment planning, and coding language is not a direct determinant of which operating system must be used. Therefore, device type is a correct factor in choosing an operating system.

What is the name for computer code that humans can understand?
正解：C
解説：
High-level programming language is the term for computer code that humans can understand. In Information Technology, high-level languages are designed to be readable and closer to natural language and mathematical notation than the binary instructions used by hardware. Examples include Python, Java, C#, and JavaScript. High-level languages use keywords, structured syntax, and abstractions that allow programmers to focus on problem solving rather than on hardware-specific details like memory addresses and CPU registers.
This improves development speed, reduces errors, and makes software easier to maintain. High-level code must be translated into machine language before it can run on a computer. This translation can occur through compilation or interpretation. Compiled language and interpreted language describe how code is executed, not whether it is human-readable. Machine language is the lowest-level code expressed in binary and is not easily understood by humans. Therefore, the correct answer for human-understandable code is high-level programming language.

What is a component of disaster recovery strategies?
正解：B
解説：
Off-site storage is a key component of disaster recovery strategies because it protects critical data from local disasters and facility failures. In Information Technology, disaster recovery focuses on restoring systems, applications, and data after disruptive events such as fires, floods, theft, ransomware, or power failures. If backups are stored only on-site, the same event that damages the primary systems can destroy the backups as well. Off-site storage places backup copies in a physically separate location, reducing the risk of total data loss. It may be implemented through secure tape vaulting, remote backup servers, third-party backup facilities, or cloud-based backup services. Disaster recovery planning typically defines backup schedules, retention periods, recovery procedures, and target recovery goals, such as recovery time objective and recovery point objective. While user authentication supports security and parallel processing relates to performance, they are not core elements that ensure data remains available after a site-level disaster.
Therefore, off-site storage is correctly identified as a component of disaster recovery strategies.
質問 # 50
A person is updating procedures for handling integer data within a database. Which value is an example of this data type?
正解：B
解説：
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.
質問 # 51
One database field needs to be restricted to only those values that are single alphanumeric symbols. Which data type should be used?
正解：A
解説：
A field restricted to single alphanumeric symbols should use the character data type because it is designed to store exactly one character. Alphanumeric symbols include letters A through Z and digits 0 through 9, and these are naturally represented as individual characters. In Information Technology and database systems, selecting a character type allows the designer to enforce a fixed length of one, which helps maintain data integrity by preventing longer entries. An integer type is used for whole numbers and would not properly handle letters, while floating point is for decimal values and is also inappropriate for single symbols. A character string type can store multiple characters, which would allow inputs longer than one symbol unless additional constraints are applied. Using the character type is therefore the most direct and standard approach for storing one letter or digit, such as a middle initial, a grade code, or a single-character category label.
Therefore, the correct data type is character.
