CompTIA ITF+ ITF Concepts and Terminology 2 — Questions and Answers
Question 1: Which term describes the process of converting data into an unreadable format to protect it from unauthorized access?
- Compression
- Encryption (Correct answer)
- Defragmentation
- Virtualization
Correct answer: Encryption
Encryption transforms data into ciphertext using an algorithm and key, making it unreadable without the correct decryption key.
Question 2: What is the term for the physical components that make up a computer system?
- Firmware
- Software
- Hardware (Correct answer)
- Middleware
Correct answer: Hardware
Hardware refers to the tangible, physical components of a computer system such as the CPU, RAM, and storage drives.
Question 3: Which concept refers to the ability of a system to continue operating even if one component fails?
- Scalability
- Fault tolerance (Correct answer)
- Interoperability
- Bandwidth
Correct answer: Fault tolerance
Fault tolerance is the capability of a system to keep functioning when one or more of its components fail.
Question 4: What does the acronym 'URL' stand for in the context of internet resources?
- Universal Resource Locator
- Uniform Resource Locator (Correct answer)
- Unified Remote Link
- Universal Retrieval Location
Correct answer: Uniform Resource Locator
URL stands for Uniform Resource Locator and specifies the address of a resource on the internet.
Question 5: In computing, what does 'latency' refer to?
- The amount of data transferred per second
- The delay before data transfer begins (Correct answer)
- The total storage capacity of a drive
- The number of cores in a processor
Correct answer: The delay before data transfer begins
Latency is the time delay between initiating a request and receiving a response, often measured in milliseconds.
Question 6: Which term describes software that manages hardware resources and provides services for computer programs?
- Application software
- Operating system (Correct answer)
- Utility software
- Middleware
Correct answer: Operating system
An operating system (OS) manages hardware resources, provides a user interface, and allows application software to run.
Question 7: What is the purpose of a 'driver' in a computer system?
- To manage user accounts and permissions
- To allow the OS to communicate with hardware devices (Correct answer)
- To compress files for storage efficiency
- To provide internet connectivity
Correct answer: To allow the OS to communicate with hardware devices
A driver is software that enables the operating system to interact with and control a specific hardware device.
