Inkjet printers are the best choice for a small company seeking full-color printing with a minimal initial cost. While they have higher operating costs (due to ink), they are affordable and capable of high-quality color output.

Why Not A (Thermal printer): Thermal printers are not designed for color printing and are typically used for labels or receipts.

Why Not C (Dot matrix printer): Dot matrix printers are outdated, noisy, and do not support full-color printing.

Why Not D (Laser printer): Laser printers have lower running costs but a higher initial purchase price, especially for color models.

The digitizer is the component responsible for detecting touch input on a screen. If touch is not registering and there's no physical damage, the digitizer may be faulty.

From CompTIA A+ 220-1101 Official Study Guide, Objective 3.1 – Mobile device hardware:

“If a touchscreen device does not respond to input and the screen is intact, the digitizer (touch sensor) may be defective.”

DisplayPort is a fully digital video interface that supports HDCP (High-bandwidth Digital Content Protection), a digital rights-management protocol used to protect copyrighted content such as movies, streaming video, and Blu-ray playback. The CompTIA A+ study guide notes that DisplayPort and HDMI support HDCP, while analog connections like VGA and DVI-A do not support HDCP because analog signals cannot enforce digital content protection.

F-type connectors are used for coaxial cabling (cable TV, satellite), not digital video output. DisplayPort's support for encrypted high-definition video streams makes it the correct answer and aligns with CompTIA’s coverage of display connectors and digital content protection technologies.
