AI Technical Summary

Benefits of technology

This new technology allows for better control over how well an electronic device operates based upon its own capabilities or needs without changing their behavior from previous modes like CPU (central processing unit) operations. It also includes features that allow multiple applications running simultaneously within one machine while still being able to perform certain functions effectively. Overall, this innovation makes it easier to manage and maintain these systems efficiently.

Problems solved by technology

Technics Problem: When starting up an electronic device with its own mother board without any other components like RAM, there are no methods available to help manage this process efficiently during normal use. Additionally, when trying to start up multiple devices simultaneously at once requires different modes such as sleep mode and background work mode.
