This is because, along with the development of computer hardware and the Internet, software is also more massive and multifunctional, requiring a large amount of resources.

Take computer games as an example. In the past, computer games used to be stored on floppy disks, but recently compact discs (CDs), which are several hundred times larger than floppy disks, are difficult to store. It uses DVD (Digital Video Disc), which has several times the capacity.

In recent years, computer games have many online games, and many of these online games are downloaded and installed on the Internet. Also, due to the high volume of data, the number of concurrent users of online games is increasing despite the development of computer hardware. It is limited.

Due to the limited number of concurrent users, some games require users to continuously connect to a computer in order to join the game, and some games have recently issued an online queue that assigns an order to access the game. Therefore, users connected to the game avoid the waiting time when reconnecting, and try to stay connected even when not using the game. As a result, the waiting time becomes longer.

In addition, various video devices such as digital cameras and digital camcorders are stored in connection with a computer, and the development of such video devices has resulted in storing or transmitting a large amount of video data to a computer. Although the Internet has evolved, when a large number of users simultaneously transmit such a large amount of data, transmission takes a long time due to the limitation of transmission capacity.

Some Internet users go to work or go out with their computers on when they are away from many time zones, or when they download large amounts of data. Therefore, unnecessary power is wasted.

Another method is remote control using the Internet. This method controls the computer to be used by the user from the remote computer using the Internet, and executes the user's desired operation. The remote control method is not only supported by each operating system itself according to an operating system (OS), but also various remote control software are commercially available. However, the remote control method using the Internet is also a waste of power because the computer to be used is always on, and remote control is possible from other computers with the Internet. That is, the problem is that it can be used only in a specific place where a computer with Internet is installed.
