Technical Skills

• 6. What are the main components of a computer?
  The main components of a computer are the central processing unit (CPU), memory, motherboard, storage devices, and input/output devices.
• 7. What are the different types of networks and their characteristics?
  The different types of networks are LAN (Local Area Network), WAN (Wide Area Network), MAN (Metropolitan Area Network), and WLAN (Wireless Local Area Network). LAN is typically limited to a small geographical area, while WAN covers a larger area. MAN is a larger version of LAN, and WLAN allows for wireless connectivity.
• 8. How does DNS (Domain Name System) work?
  DNS is a system that translates domain names (e.g., www.example.com) into IP addresses (e.g., 93.184.216.34), allowing computers to communicate with each other over the internet. When a user enters a domain name, their device sends a request to a DNS server, which then returns the corresponding IP address.
• 9. What is the purpose of RAID (Redundant Array of Independent Disks)?
  RAID is a data storage technology that combines multiple physical disks into a single logical unit for improved performance, reliability, and capacity. It uses a variety of techniques such as mirroring, striping, and parity to distribute data across multiple drives and safeguard against data loss.
• 10. What is the difference between TCP (Transmission Control Protocol) and UDP (User Datagram Protocol)?
  TCP is a connection-oriented protocol that guarantees reliable and secure data transfer between devices, while UDP is a connectionless protocol that provides faster transfer but may result in data loss. TCP is typically used for applications such as web browsing and email, while UDP is used for real-time applications such as video conferencing and online gaming.

Decision-Making & Problem-Solving

• 11. How do you approach a problem when you don't have all the necessary information?
  My first step is to gather as much information as possible from available sources and consult with team members or experts if needed. If all information is not available, I make informed assumptions based on my knowledge and experience to come up with a solution.
• 12. Can you give an example of a time when you had to make a difficult decision?
  In my previous role, I had to make a decision regarding a system upgrade that had a limited budget and timeline. I consulted with the team to identify critical requirements and prioritized accordingly. I also recommended alternatives that were more cost-effective and achievable within the given timeline.
• 13. How do you handle conflicts in a team setting?
  I believe in open communication and actively listening to all perspectives to understand the root cause of conflicts. I then work with the team to find a mutually beneficial solution and ensure that all team members feel heard and respected.
• 14. How do you troubleshoot a technical issue when you don't have access to the internet?
  In such situations, I rely on my experience and knowledge of troubleshooting techniques to identify the root cause and find a solution. I also make use of offline resources and consult with colleagues or experts if needed.
• 15. How do you stay organized and ensure all tasks are completed on time?
  I make use of project management tools to keep track of tasks and deadlines. I also prioritize tasks and regularly communicate with my team to ensure we are on the same page. In case of unexpected delays, I re-evaluate priorities and adjust the plan accordingly.
