NEW QUESTION # 121
Which item is an input device?
Answer: D
Explanation:
An input device is any hardware device that sends data to a computer, allowing you to interact with and control it. Input devices enable users to input information into the computer system. Let's break down the options:
*Flash Drive (A): A flash drive (also known as a USB drive or thumb drive) is a storage device, not an input device. It allows you to store and transfer data but does not directly input data into the computer.
*CD (B): A CD (compact disc) is also a storage medium, typically used for storing audio, video, or software files. Like a flash drive, it is not an input device.
*Scanner : A scanner is a classic example of an input device. It captures physical documents, images, or text and converts them into digital data that the computer can process. Scanners are commonly used for tasks like digitizing photos, creating PDFs, or scanning documents.
*Printer (D): A printer is an output device, not an input device. It produces hard copies (printed documents) based on digital data received from the computer.
In summary, the correct answer is C. Scanner, as it directly inputs data into the computer system.

NEW QUESTION # 122
A person is updating procedures for handling integer data within a database. Which value is an example of this data type?
Answer: B
Explanation:
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.
NEW QUESTION # 123
What is the term used to describe additional requirements that are added after project initiation?
Answer: A
Explanation:
In project management, scope creep refers to the uncontrolled expansion of a project's scope beyond its original boundaries. Here's a breakdown:
1.Project Initiation:
oProject initiation is the first step in starting a new project.
oDuring this phase, you establish why you're doing the project and what business value it will deliver.
oThe goal is to secure buy-in from key stakeholders based on the project's initial definition.
2.Scope Creep:
oOnce a project is underway, additional requirements or changes may arise.
oThese unplanned additions can lead to scope creep.
oExamples include:
New features requested by stakeholders.
Enhancements beyond the original scope.
Unforeseen requirements emerging during execution.
3.Impact of Scope Creep:
oScope creep can:
Delay the project timeline.
Increase costs due to additional work.
Affect quality if rushed changes are made.
Create frustration among team members.
4.Managing Scope Creep:
oTo prevent scope creep:
Define clear project boundaries during initiation.
Document requirements thoroughly.
Regularly review and assess any proposed changes.
Communicate with stakeholders about trade-offs.

NEW QUESTION # 124
Which operating system component schedules when each application runs?
Answer: B
Explanation:
The kernel schedules when each application runs. In operating systems, scheduling is the process of deciding which program or process gets access to the CPU and for how long. This is essential for multitasking, where many applications appear to run at the same time. The kernel contains the process scheduler, which manages ready queues, assigns CPU time slices, handles context switching, and enforces priority rules so that system tasks and user applications run smoothly. In Information Technology, this function is part of core resource management, alongside memory management and device coordination. The user interface controls how the system is presented to users, such as command-line or graphical interfaces. The file manager focuses on storing, retrieving, and organizing files and folders. Drivers translate operating system commands into device- specific actions for hardware such as keyboards, printers, and disk controllers. Since scheduling is a core OS responsibility handled internally, the correct component is the kernel.
NEW QUESTION # 125
What are two differences between a handheld computer and a desktop?
Choose 2 answers.
Answer: D
Explanation:
1.Smaller Screens:
oVerified Answer: Handheld computers (such as smartphones and tablets) have smaller displays compared to desktop computers.
oExplanation: Handheld screens are typically around 3-5 diagonal inches for phones and up to 9-12 inches for tablets. In contrast, desktop screens range from 20-30 inches diagonally.
oReferences: 1
2.Processing Power and Customizability:
oVerified Answer: Desktop computers usually have more processing power, memory, and storage capacity than handheld devices.
oExplanation: Desktops are ideal for resource-intensive tasks like video editing, gaming, and software development. Handheld devices, while becoming more powerful, are still constrained by size and battery life considerations.
