WGU Introduction to IT Introduction-to-IT Prüfungsfragen mit Lösungen (Q74-Q79):

74. Frage
What type of software utilizes a commercial software license?

A. Open Source
B. Shareware
C. Proprietary
D. Public Domain

Antwort: C

Begründung:
*Proprietary software refers to software that is closed source and is commercially licensed. It is developed by a specific company or individual, and its source code is not publicly available.
*In proprietary software, the end user does not have the authority to modify or reuse the software code. The software is typically distributed as operational code only, without providing access to the underlying source code.
*Proprietary licenses often include terms that prohibit "reverse engineering" of the object code with the intention of obtaining the source code.
*Examples of proprietary software include Microsoft Office, Adobe Photoshop, and many commercial applications.
*References:
o1 Snyk. "What is a software license? 5 Types of Software Licenses Explained." Link o2 Turing. "Open Source vs. Commercial Software License: What Do You Need?" Link o3 License.md. "What type of license is needed for Commercial Use Software?" Link o4 Thales Group. "Commercial License FAQ." Link Note: While proprietary software utilizes a commercial software license, it's essential to understand that open-source software (which is freely available and allows modification and reuse of source code) falls under a different category. However, for the specific question, the correct answer is A. Proprietary.

75. Frage
Which image represents the basic structure of a computer network?

A. Exhibit D
B. Exhibit B
C. Exhibit C
D. Exhibit A

Antwort: A

Begründung:
the basic structure of a computer network is the one depicting cloud computing. In this image, a blue cloud labeled "Cloud" is connected to four different types of devices: a desktop computer, tablet, phone, and laptop.
Each device has an icon representing its type, and all devices are connected to the cloud, symbolizing data access and storage on the cloud.

76. Frage
Which type of communications media uses light waves to transmit data?

A. Fiber optic
B. Coaxial
C. Twisted pair
D. Radio towers

Antwort: A

Begründung:
Fiber optic communication uses light waves to transmit data. Here's how it works:
1.Fiber Optic Cable Structure:
oA fiber optic cable consists of a core made of glass or plastic, surrounded by a cladding layer.
oThe core acts as a light guide, allowing light to travel through it by total internal reflection.
oThe cladding layer ensures that the light remains within the core.
2.Light Propagation:
oWhen data needs to be transmitted, a light source (usually a laser or LED) sends pulses of light into the fiber.
oThe light travels down the core, bouncing off the cladding due to total internal reflection.
oAs a result, the light signal remains confined within the core.
3.Advantages of Fiber Optics:
oHigh Bandwidth: Fiber optics can transmit large amounts of data quickly.
oLow Attenuation: Light signals experience minimal loss over long distances.
oImmune to Electromagnetic Interference: Unlike copper cables, fiber optics are not affected by electromagnetic fields.
oSecure: It's difficult to tap into fiber optic cables without detection.
4.Applications:
oInternet Backbone: Fiber optics form the backbone of the global internet, connecting continents.
oTelecommunications: Used for long-distance phone calls and high-speed internet.
oData Centers: Within data centers, fiber optics connect servers and storage devices.
oCable TV: Many cable TV networks use fiber optics for signal distribution.

77. Frage
What is the hardware component that contains soldered parts and slots for other pieces of hardware that can be removed?

A. Expansion bus
B. Motherboard
C. System clock
D. Hard drive

Antwort: B

Begründung:
The motherboard is the main circuit board in a computer that contains soldered components and provides slots and connectors for removable hardware. In Information Technology hardware fundamentals, the motherboard holds essential components such as chipset circuitry, connectors, and sometimes integrated devices like audio or network controllers. It also provides sockets and slots for components that may be installed or replaced, such as the CPU socket, RAM slots, and expansion slots like PCIe for graphics cards or other add-on cards.
The motherboard includes pathways called buses that enable communication among the processor, memory, storage, and peripheral devices. A hard drive is a storage device and does not serve as the central board for system components. The system clock is a timing mechanism, not a physical board containing multiple slots.
An expansion bus refers to a communication pathway standard, not the full board that hosts multiple connectors and soldered parts. Therefore, the component described is the motherboard.

78. Frage
An IT department employee is identifying the Boolean data in a system. What is one example of this type of data?

A. The price of gas in dollars and cents
B. The first letter of a person's last name
C. Whether a number is positive or not
D. The last name of a newly hired employee

Antwort: C

Begründung:
Boolean data represents a logical value with only two possible states, typically true or false. In Information Technology, Boolean types are foundational for conditions, comparisons, control flow, and database fields that store yes-or-no style information. The example, "Whether a number is positive or not," fits Boolean data because the statement can be evaluated as true if the number is greater than zero, or false otherwise. This two- state characteristic is exactly what defines Boolean logic. The other options describe different data types: the first letter of a last name is a character, a full last name is a character string, and the price of gas in dollars and cents is numeric with decimals, typically stored as a floating-point or fixed-point decimal type. Boolean fields are widely used in systems for flags such as active or inactive, approved or not approved, and eligible or not eligible. Therefore, the correct example of Boolean data is whether a number is positive or not.
