Top 10 Computer Technician Interview Questions and Answers [Updated 2024]

Sample Answer
In my previous position, our company moved to a new CRM system. Many team members, especially those in non-technical roles, found it challenging to adapt to the new system. I was tasked with training these individuals. To do this, I took the time to understand their roles and how they would interact with the CRM, then translated the technical details into everyday analogies that related to their roles. For example, I described the process of logging customer interactions as filling out a digital diary. I also used visuals and step-by-step guides. As a result, the team members were able to understand and use the new CRM system efficiently, reducing downtime in their roles.

Sample Answer
First, I would confirm if the power source is functional and the PC is properly connected. If this is not the issue, I would check the hardware components such as the motherboard, RAM, hard drive, and power supply unit. If the hardware is fine, I would look into the software. I would check the BIOS settings and if necessary, I would proceed with booting the system in safe mode to identify if any drivers or updates are causing the issue. If all these steps fail to solve the problem, I would consider a system restore or consult with a more experienced technician or the manufacturer.

Sample Answer
DHCP stands for Dynamic Host Configuration Protocol. It’s a network protocol used in IP networks where a DHCP server automatically assigns an IP address and other network configuration parameters to each device on the network, so they can communicate with other IP networks. The DHCP server manages a pool of IP addresses and information about client configuration parameters such as default gateway, subnet mask, and DNS servers. When a device is turned on and connected to a network, the DHCP client sends a request to the DHCP server to obtain an IP address. The server then responds with an IP address this is the ‘offer’. The client then sends a request for this IP address, and finally, the server acknowledges this request. This process is often referred to as DORA – Discover, Offer, Request, Acknowledge.

Sample Answer
A modem is a device that connects a network to the Internet. The modem takes the signal from your ISP and transforms it into a signal your local devices can use. On the other hand, a router is a device that takes that Internet signal and distributes it to various devices in your home or office. In essence, a modem brings the Internet to your home, and the router disperses that Internet connection to your devices.

Sample Answer
To set up a local area network, I would start by understanding the requirements of the organization – how many computers and other devices need to be connected, what kind of data needs to be shared, and any security considerations. Then, I would design the network, selecting the appropriate hardware and software. This might include routers, switches, and Ethernet cables, as well as network operating systems and security software. Once everything is installed, I would configure the network settings on each device, ensuring they’re all able to communicate with each other. Finally, I would test the network to ensure it’s working correctly, and troubleshoot any issues that arise. I’ve completed several certifications in networking, which have given me a strong foundation in these processes.

Sample Answer
First, I would conduct a thorough assessment of the existing system and the requirements of the new operating system. I would then create a detailed plan that includes a schedule, resources needed, and potential risks. I would set up a test environment to try out the new operating system and troubleshoot any issues. After that, I would implement the migration in phases to minimize disruption to the company. Finally, I would provide ongoing support to help users adjust to the new system and address any issues that come up.

Sample Answer
IPv4 and IPv6 are versions of Internet Protocol that are used to identify devices on a network. The main difference between the two lies in their address spaces. IPv4 uses a 32-bit addressing scheme which allows for a total of around 4.3 billion addresses. On the other hand, IPv6 uses a 128-bit scheme which allows for a virtually unlimited number of devices to be connected to the Internet. The transition from IPv4 to IPv6 was primarily due to the exhaustion of IPv4 addresses. Other differences include the structure of the IP packets, the method of handling fragmentation, and the inclusion of IPsec support in IPv6.

Sample Answer
Regularly updating a computer’s operating system and applications is crucial for several reasons. These updates often include security patches that fix vulnerabilities that could be exploited by hackers. They also include bug fixes to resolve any issues in the software, and sometimes, new features that enhance the functionality of the software. The process for updating will depend on the specific system and applications in use. However, generally, for the OS, one would go to the system settings and check for updates. For applications, some may have an auto-update feature, and for others, you would need to go to the software’s help or settings menu and check for updates there. It’s important to ensure that your system is connected to the internet and that it won’t be turned off during the update process as this could cause problems.

Sample Answer
BIOS stands for Basic Input Output System. It is a type of firmware that is used during the boot process of a computer. The BIOS tests the system, checks the hardware, and loads the bootloader, which then loads the operating system. Updating a BIOS can be a critical task and it should be done carefully. Usually, it involves downloading the updated firmware version from the manufacturer’s website, saving it on a USB drive or the hard drive, and then restarting the computer and entering the BIOS setup to start the update process. It’s crucial to ensure that the computer doesn’t lose power during this process as it can corrupt the BIOS and render the computer unusable.

Sample Answer
If I encountered an unfamiliar software issue, I wouldn’t panic. I would first try to understand the problem by replicating it and observing its behavior. Then, I would use online resources like technical forums and knowledge bases to gather information about the issue. If I still couldn’t resolve it, I would reach out to my colleagues or superiors for advice. If all else fails, I would consider contacting the software vendor for support. Throughout this process, I would document everything I do for future reference and to help others who might encounter the same issue.
