From the time the system is introduced, users operate the system by adding various files and data, including peripheral devices and application software, and these are all intangible assets that can be said to be valuable assets. We aim to adapt these to technological advances and build a system for a new era that meets the needs of users in today's world, where ever-innovating technology and online communication with countries around the world are commonplace.
