20+ practice questions focused on Tech Concepts and Terminology — one of the most tested topics on the CompTIA Tech+ (FC0-U71) exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Tech Concepts and Terminology PracticeA network technician needs to perform a bitwise AND operation on two binary numbers: 10110110 and 11001101. What is the result in decimal?
Explanation: Bitwise AND compares each bit position: 1 AND 1 = 1, otherwise 0. Computing 10110110 AND 11001101 yields 10000100 in binary, which equals 128 + 4 = 132 in decimal.
A file is compressed using a lossless algorithm. Which of the following file types is most likely the result?
Explanation: PNG uses lossless compression (DEFLATE) and preserves every pixel exactly, making it the correct answer for a file produced by a lossless algorithm. It is widely used for images where fidelity matters, such as screenshots, logos, and line art.
Which of the following best describes the function of an operating system?
Explanation: An operating system is the software layer that manages hardware resources—CPU, memory, storage, and peripherals—and provides services and APIs that application software relies on. It handles process scheduling, memory allocation, file systems, and device drivers. This definition distinguishes it from applications that run on top of it.
A system administrator is configuring a server to provide email services for a small business. The business wants to avoid managing the underlying infrastructure. Which cloud service model best fits this need?
Explanation: SaaS delivers fully managed applications where the provider handles all underlying infrastructure, patching, and maintenance — the customer simply uses the email service. This matches the requirement to avoid managing infrastructure. Examples include Microsoft 365, Google Workspace, and Zoho Mail.
A network technician is analyzing a hexadecimal IP address representation. Which TWO of the following are common uses of hexadecimal notation? (Select TWO).
Explanation: Option B is correct because hexadecimal notation is commonly used to express memory addresses (e.g., 0x7FFF) and MAC addresses (48-bit values written as 12 hex digits like 00:1A:2B:3C:4D:5E). Option E is correct because HTML/CSS colour codes are conventionally written in hexadecimal (e.g., #FF0000 for red), where each pair of hex digits represents the red, green, and blue channel values. Option A is a true statement about hexadecimal's character set, but it describes the format rather than a use, so it does not answer the question asking for common uses. Option C is also a true fact about hexadecimal (one hex digit encodes 4 bits), but again it is a property, not a use. Option D is simply false, since hexadecimal is a base-16 system, not base-8 (base-8 is octal).
