Explanation
Liquid cooling is a method of cooling the CPU by circulating a liquid through a closed loop that absorbs heat from the CPU and transfers it to a radiator. Liquid cooling is more effective and quieter than air cooling, which uses a fan and a heat sink. However, liquid cooling is also more expensive and complex to install. Upgrading the thermal paste, using a copper heat sink, or upgrading the CPU fan are ways to improve air cooling, but they will not lower the CPU temperature as much as liquid cooling. References:

Based on the information recorded by the technician, the network connection appears to be functioning normally. The user's computer is properly configured with an IPv4 address, subnet mask, and default gateway, which should allow the user to access the internet and online videos. The high download and upload speeds and low ping time recorded from the test laptop also indicate that the network is working well. However, the user's inability to watch online videos suggests that there might be an issue with the network card (NIC) on the user's computer. The NIC might be faulty or malfunctioning, which is preventing the computer from receiving and processing the video data. The technician should try replacing the NIC to resolve the issue.

Explanation
RAID 10 combines the benefits of RAID 0 and RAID 1. It uses a striped configuration across multiple disks (similar to RAID 0) to provide high-speed read and write access. Additionally, it also mirrors the striped array onto a second set of drives (similar to RAID 1), providing redundancy in case of a drive failure.

The most likely reason the data transfer failed is D. The older phone utilized different wireless protocols.
Wireless protocols are the standards that devices use to communicate with each other over a wireless network. Different wireless protocols have different features, such as speed, range, security, and compatibility. If the older phone and the new phone use different wireless protocols, they may not be able to transfer data smoothly or at all. For example, if the older phone uses Wi-Fi Direct and the new phone uses Bluetooth, they may not be able to connect or recognize each other.
To avoid this problem, you should make sure that both devices support the same wireless protocol and that they are in range of each other. You can also use a third-party app or service that can transfer data between different devices, such as Smart Switch1 or Move to iOS2. These apps can help you transfer data such as contacts, photos, messages, and more from your old phone to your new phone.
