USB Type-B ==> A square-shaped connector with beveled corners and a notch on top, commonly used for printers and external hard drives.
USB Type-C ==> The newest, smaller rectangular connector with rounded corners; supports Thunderbolt 3 functionality, power delivery, and is multipurpose for many devices.

8. When installing new software, why is it important to verify hardware compatibility before proceeding?

to ensure that all optional hardware features are fully enabled and utilized by the software, enhancing overall user experience
to confirm that the operating system environment aligns with the software requirements, even if hardware specifications vary slightly
to reduce the risk of encountering functionality limitations or instability due to mismatches between the software demands and the hardware capabilities of the system
to avoid installation failures, crashes, or poor performance from insufficient hardware

9. Why might a modern 64-bit application fail to install on an older computer with a 32-bit processor?

The system drive is formatted as FAT32 instead of NTFS.
The processor architecture is not compatible with the application.
The installation process is slowed down due to excessive background processes consuming system resources.
The RAM is not operating at full speed.

10. A user reports that the USB headset stopped working after a recent system update. The headset lights up when plugged in, but no sound plays and the microphone is not detected. What is the best first step a technician should take using Device Manager?

Launch Task Manager and check the Processes tab.
Open Device Manager and check for warning icons under Sound, Video and Game controllers.
Open Performance Monitor to analyze the headset data throughput and system resource allocation.
Run Disk Cleanup to remove driver logs.

11. Why is it important for IT technicians to follow electrical safety guidelines when working with computer and printer hardware?

It helps avoid electrical fires, injuries, and equipment damage by ensuring safe handling and grounding.
It minimizes the risk of hardware failure due to overheating from power mismatches.
It allows technicians to safely swap components like AC adapters across different devices to maintain uptime.
It ensures all connected devices communicate correctly by maintaining proper voltage signaling.

12. Why must a support technician identify a computer’s host name when responding to a user issue?

It helps confirm the system has a valid IP address before performing network diagnostics.
It reveals the current operating system version and whether the device needs an update.
It ensures the technician works on the correct device, especially in environments with similar systems.
It indicates whether the device uses a wired or wireless connection.

13. A user reports that their desktop computer cannot access internal company websites, but can browse external IPv6 enabled websites without issues. When the support technician issues the ipconfig command, the technician notices that the device has an IPv6 address and an IPv4 address of 169.254.0.2. What is the most likely cause of the internal access issue?

The device’s IPv6 address is invalid and needs to be updated manually.
The desktop cannot contact the DHCP server to get a valid IPv4 address.
The user’s browser is outdated and cannot handle IPv6-formatted URLs.
The DNS cache needs to be flushed for external websites to load properly.

14. Which Task Manager section details the CPU model, installed RAM, disk usage, and network IP addresses?
