2. Define the difference between RAM and ROM.
Answer: RAM (Random Access Memory) is volatile memory used to store data that is currently being processed by the CPU. In contrast, ROM (Read-Only Memory) is non-volatile memory that permanently stores firmware and system instructions that do not change.
3. What are the common types of network topologies?
Answer: The common types of network topologies include:
- Star: All devices are connected to a central hub.
- Bus: All devices share a single communication line.
- Ring: Devices are connected in a circular fashion, with each device connected to two others.
4. How do you secure a wireless network?
Answer: To secure a wireless network, you can:
- Enable WPA3 or WPA2 encryption.
- Use a strong password for the network.
- Change the default SSID and password of your router.
- Disable WPS (Wi-Fi Protected Setup).
- Regularly update router firmware.
5. What should you do if a computer fails to boot?
Answer: If a computer fails to boot, follow these troubleshooting steps:
- Check power supply and connections.
- Listen for any error beeps or codes.
- Disconnect all peripherals and try booting again.
- Boot into Safe Mode to diagnose software issues.
- Check for hardware issues, such as faulty RAM or hard drive.
6. What is the purpose of an IP address?
Answer: An IP address (Internet Protocol address) serves as a unique identifier for a device on a network. It allows devices to communicate with each other and ensures that data is sent to the correct recipient.
