18000 Hz refers to the frequency of a sound wave, not its volume. The loudness of a sound is typically measured in decibels (dB), not in hertz. Therefore, it is not accurate to say that 18000 Hz is loud. The perception of loudness depends on the amplitude of the sound wave, which is measured in decibels. **

A non-WiFi-enabled computer can be connected to the internet via a LAN cable by plugging one end of the LAN cable into the computer's Ethernet port and the other end into a LAN port on a router or modem. The computer will then be able to access the internet through the wired connection. This method provides a reliable and secure connection, especially in situations where WiFi signals may be weak or unreliable. **

An Ethernet-enabled mobile phone is a device that has the capability to connect to the internet using an Ethernet cable. This type of phone can be directly plugged into a wired network connection to access the internet, rather than relying on a Wi-Fi or cellular data connection. Ethernet-enabled mobile phones are useful in situations where a stable and secure internet connection is needed, such as in an office or business setting. **

Mobile data saving can be enabled on a smartphone by going to the settings and selecting the "Data Usage" or "Network & Internet" option. From there, users can turn on the "Data Saver" feature, which restricts background data usage and reduces the amount of data used by apps. Additionally, users can manually restrict data usage for specific apps by going to the app settings and selecting the "Restrict app background data" option. This can help conserve data and prevent unnecessary usage. Finally, users can also monitor their data usage regularly and set data usage limits to avoid exceeding their data plan. **

To divide 18000 by 5, you can simply use long division. Start by dividing 18 by 5, which equals 3 with a remainder of 3. Then bring down the next digit, 0, to make 30. 30 divided by 5 equals 6 with no remainder. So, the final answer is 3600. **

It is generally recommended to keep both IPv4 and IPv6 enabled on your network. While IPv6 is the newer protocol and offers many advantages over IPv4, there are still many devices and services that primarily use IPv4. By keeping both protocols enabled, you ensure compatibility with all devices and services on the internet. Additionally, having both protocols enabled provides redundancy in case one protocol experiences issues or outages. **

The decision of whether to study architecture at TU Dresden or BTU Cottbus depends on your personal preferences and career goals. TU Dresden is a larger and more established university with a strong reputation in architecture, offering a wider range of resources and opportunities.
