WGU Introduction to IT Sample Questions (Q32-Q37):

NEW QUESTION # 32
What is the type of software that is a functionally limited version of software available at no cost?

A. Closed-source
B. Public domain
C. Shareware
D. Freeware

Answer: C

Explanation:
Shareware is software distributed at no cost initially but typically provided as a limited version with restrictions. The limitations may include reduced features, a trial period, watermarks, usage limits, or reminders to purchase the full product. In Information Technology, shareware is often used as a marketing and distribution model that allows users to evaluate software before buying a license to unlock full functionality. This differs from freeware, which is available at no cost and is usually fully functional, though the author retains copyright. Public domain software has no copyright restrictions and can be used, modified, and redistributed freely, which is different from a limited trial distribution model. Closed-source refers to software where the source code is not publicly available, but it does not automatically mean the software is free or functionally limited. Since the question describes a functionally limited version available at no cost, the correct type of software is shareware.

NEW QUESTION # 33
What does a modem do?

A. Provides services, such as website hosting and routing, for various devices
B. Serves as a connection between the customer network and the internet service provider
C. Manages traffic by maintaining a table of known devices on the network
D. Provides a barrier between a trusted private network and an untrusted network

Answer: B

Explanation:
A modem serves as the connection between the customer network and the internet service provider. In Information Technology networking, modem stands for modulator-demodulator. Traditionally, it converts outgoing digital data from a computer or router into a form suitable for transmission over the provider's communication medium and converts incoming signals back into digital data. Depending on the service type, this may involve cable, DSL, fiber, or cellular technologies, each using specific signaling methods. The modem typically terminates the ISP line and hands off connectivity to a router or directly to a computer.
Option A describes routing or switching behavior rather than a modem function. Option B describes a server that offers hosted services. Option D describes a firewall, which protects a trusted network by filtering traffic from untrusted networks. Since the essential purpose of a modem is enabling communication between the customer premises equipment and the ISP network, the correct choice is that it serves as the connection between the customer network and the internet service provider. Therefore, the correct answer is option C.

NEW QUESTION # 34
A person is preparing a pizza, which needs to be baked for 18 minutes at 400°F. Which component of the data- information-knowledge-wisdom DIKW hierarchy is exemplified by the value 18 in this scenario?

A. Information
B. Knowledge
C. Wisdom
D. Data

Answer: D

Explanation:
In the DIKW hierarchy, the value 18 by itself represents data because it is a raw numeric fact without meaning until it is connected to context. In Information Systems fundamentals, data is defined as unprocessed facts such as numbers, symbols, or measurements that do not explain their purpose on their own. The number
18 could represent many things: minutes, dollars, items, or a temperature reading. Once the number is connected to the statement baked for 18 minutes, it becomes information because the data has been given context and meaning. Knowledge would involve understanding how baking time interacts with oven type, pizza thickness, or cooking technique, and being able to apply that understanding to adjust cooking when conditions change. Wisdom would involve making the best overall decision, such as considering health, safety, and preventing burning based on real-world judgment. Since the question asks specifically about the value 18 in isolation, it matches the DIKW definition of data as a raw fact. Therefore, the correct answer is data.

NEW QUESTION # 35
What translates and executes source code into machine language one line at a time?

A. Operating system
B. Assembler
C. Interpreter
D. Compiler

Answer: C

Explanation:
An interpreter translates and executes source code one line at a time. In Information Technology, interpretation is a method of program execution where each statement is read, translated into machine-level actions, and executed immediately. This allows programmers to test and debug quickly because errors are often reported at the line where execution stops. Many scripting languages and interactive environments use interpreters, supporting rapid development and flexibility. Unlike a compiler, which translates the entire program into a machine code file that can be executed later, an interpreter generally requires the source code or intermediate representation to be present at runtime. An assembler is used for assembly language and converts mnemonic instructions into machine code, but it is not typically described as executing source code one line at a time. The operating system manages system resources and provides services, but it is not the tool that translates programming language source code into machine language during execution. Therefore, the correct answer for translating and executing code line by line is interpreter.

NEW QUESTION # 36
What is the role of the compiler?

A. To take the most recent line of code, translate it, and execute the machine code
B. To create an executable program by translating all of the code at one time
C. To run scripting languages to test one line of code at a time
D. To create executable code that is compatible with different operating systems

Answer: B

Explanation:
1.Lexical Analysis:
oThe source code is first tested by the compiler's lexer, which breaks it down into tokens (such as keywords, identifiers, operators, and punctuation).
oThis step identifies the individual elements of the program.
2.Syntactic and Semantic Analysis:
oThe compiler performs syntactic analysis, checking the source code for syntax errors and ensuring it follows the correct language-specific rules.
oIf any errors occur, the compiler throws an error and stops the compilation.
oAdditionally, the compiler performs semantic analysis to find the meaning of the code.
oIt checks for logical errors, such as type mismatches, undeclared variables, and incorrect usage of operators.
3.Optimization:
oOnce the code is syntactically correct, the compiler performs low-level optimization to improve performance.
oThis may involve reducing memory usage or optimizing code for speed by rearranging instructions or eliminating unnecessary operations.
4.Output Code Generation:
oFinally, the compiler generates machine code corresponding to the original source code.
oThe resulting machine code resides in a binary file that the computer's hardware can execute directly.
Why Do We Use Compilers?
*Compilers catch syntax and semantic errors before running the code, saving time and preventing crashes.
*They optimize code for efficient execution, resulting in faster, more compact programs.
Disadvantages of a Compiler:
*Compiled code is platform-dependent, meaning it produces a machine-specific executable file.
*Code compiled on one type of machine won't run on another type without recompilation1.
