Application virtualization is a technique that allows an application to run on a computer without being installed or affecting other applications on the system. Application virtualization creates a virtual environment for the application that isolates it from the underlying operating system and hardware. This way, the technician can verify the application deployment will not affect other legacy applications on the end users’ computers.

802.11 ax is a wireless networking protocol that supports both 2.4GHz and 5GHz devices, as well as backward compatibility with previous 802.11 standards. 802.11 ax offers higher data rates, lower latency, increased capacity, and improved power efficiency than previous protocols. It is also known as Wi-Fi 6 or High Efficiency Wireless (HEW). Reference: (page 82)

The issue described suggests that the home USB-C adapter may not be compatible with the laptop or may not meet the necessary power requirements to charge the device. Providing the user with an Original Equipment Manufacturer (OEM) power supply ensures compatibility and reliability, as OEM chargers are specifically designed to work with the laptop model in question. This solution ensures that the user can work efficiently both at home and in the office without facing charging issues, as OEM power supplies adhere to the specific voltage and amperage requirements of the device.

ECC stands for Error Correction Code, which is a type of memory that can detect and correct data errors that may occur during processing or transmission. ECC memory is commonly used in servers that handle sensitive or critical information, such as payment information online, because it can reduce the risk of data corruption, system crashes, or security breaches12.

DDR4 is a generation of DDR technology, which stands for Double Data Rate. DDR4 memory is faster and more power-efficient than its predecessors, but it does not necessarily have ECC functionality. DDR4 memory can be either ECC or non-ECC1.

VRAM is Video RAM, which is a type of memory that is dedicated to storing graphics data for display. VRAM is usually found on graphics cards or integrated graphics processors, not on servers3.

SODIMM is Small Outline DIMM, which is a type of memory module that has a smaller size and lower profile than regular DIMMs. SODIMMs are typically used in laptops, notebooks, or other compact devices, not on servers3.
