Technical Questions

• 16. Can you explain the difference between a LAN and a WAN?
  A LAN (Local Area Network) is a network of computers and devices that are connected in a small geographical area, such as a home or office. A WAN (Wide Area Network) is a network of computers and devices that are connected over a large geographical area, such as multiple offices in different cities.
• 17. What is DNS, and how does it work?
  DNS (Domain Name System) is a system that translates domain names (such as google.com) into IP addresses (such as 216.58.219.142) to establish a connection between devices on a network. It works by sending a request to a DNS server, which then returns the IP address of the domain name, allowing the device to connect to the appropriate server.
• 18. Can you explain the difference between HTTP and HTTPS?
  HTTP (Hypertext Transfer Protocol) is a protocol used for transferring data between a web server and a web browser. HTTPS (Hypertext Transfer Protocol Secure) is a secure version of HTTP, which encrypts data to protect it from being intercepted by third parties. HTTPS is commonly used for e-commerce and other forms of sensitive data exchange.
• 19. Can you walk me through the steps of troubleshooting a network connectivity issue?
  1. Check the physical connections, ensuring all cables are securely connected.
  2. Verify IP and DNS settings on the device.
  3. Use the command prompt to ping the IP address of the router.
  4. If the router responds, try pinging an external website to check internet connectivity.
  5. If the router does not respond, reset the router and modem.
  6. If the issue persists, contact the ISP for further assistance.
• 20. What is SQL and its role in database management?
  SQL (Structured Query Language) is a programming language used to manage and manipulate data stored in databases. It is used to create databases, tables, and insert, update, and delete data. SQL also allows for complex queries and the retrieval of specific information from databases.
