The question asks how the value 9 can be represented using only ones and zeros, which is the definition of binary. In binary, the decimal number 9 is represented as 1001.

''Binary is a base-2 numeral system that represents numeric values using only two symbols: 0 and 1. Computers use binary to process and store all data.'' --- CompTIA ITF+ Study Guide

Correct answe r: C

A flat file is a simple database format often stored as a plain text or CSV file. It is ideal for small data sets where speed and simplicity are required.

''Flat files are simple and fast for storing small amounts of data and are easy to process without requiring a full database management system.'' --- CompTIA ITF+ Data Concepts

Correct answe r: A

The correct answer is B. 101101. Hexadecimal is base-16. The hexadecimal value 2D equals 2 16 plus D. Since hexadecimal letters A through F represent decimal values 10 through 15, D represents 13. Therefore, 2D equals 32 + 13 = 45 in decimal. In binary, 45 is 101101 because it equals 32 + 8 + 4 + 1.

Exact Extract/Reference: The CompTIA Tech+ Study Guide explains that hexadecimal is ''base-16'' and that letters A through F represent decimal numbers 10 through 15. It also provides the binary place values used for conversion: 128, 64, 32, 16, 8, 4, 2, and 1.

The CompTIA Tech+ Study Guide highlights that:

''If no sound is coming from your speakers, even after confirming they're powered and connected, check your sound settings. The wrong output device may be selected---especially when multiple audio devices are present.''

This describes a misconfigured output---where the OS is sending audio to the wrong device (e.g., Bluetooth or HDMI).
