A method of operating a user computer device communicating with a resource sharing network server via a network, comprising:
The user computer device includes a memory including a first memory space and a second memory space separated from each other, and a nonvolatile storage medium including a first storage space and a second storage space separated from each other,
The method is
controlling an application program to at least partially occupy the second memory space and the second storage space, wherein access of the application program to the first memory space and the first storage space is blocked;
receiving a leave-off alarm signal from the time and attendance management server by communicating with the time and attendance management server through the network;
generating a virtual machine that at least partially occupies the first memory space of the memory and the first storage space of the nonvolatile storage medium based on the leave alarm signal;
informing the resource sharing network server of the creation of the virtual machine; and
When a resource request signal is received from the resource sharing network server, the first memory space of the memory occupied by the virtual machine and the first storage space of the non-volatile storage medium at least partially with the resource sharing network server; A method comprising the step of sharing. 9. The method of claim 8,
The user computer device further comprises a processor comprising a plurality of processing units;
the virtual machine further occupies a portion of the plurality of processing units,
The step of sharing with the resource sharing network server includes further sharing, at least in part, the portion of the plurality of processing units with the resource sharing network server when the resource request signal is received. delete 9. The method of claim 8,
The virtual machine is created by a hypervisor,
wherein the application program runs under an operating system associated with the hypervisor. delete 9. The method of claim 8,
The user computer device further comprises a user interface,
The generating of the virtual machine includes generating the virtual machine based on the leave alarm signal when a user input indicating consent to the creation of the virtual machine is received through the user interface. A user computer device communicating with a resource sharing network server over a network, comprising:
a communicator connected to the network;
a memory comprising a first memory space and a second memory space separated from each other;
a nonvolatile storage medium including a first storage space and a second storage space separated from each other; and
at least one processor configured to control the communicator, memory, and non-volatile storage medium;
The at least one processor,
controlling an application program driven by the at least one processor to at least partially occupy the second memory space and the second storage space, wherein the application program accesses the first memory space and the first storage space is blocked;
communicate with a time and attendance management server through the network, and generate a command based on an leave alarm signal from the time and attendance management server;
