14. A terminal device, comprising:

a processor configured to:

obtain an estimated total length of time to be taken for an update of software stored in a memory device coupled with the terminal device,

obtain a measured first length of time between a point of time of starting the update of the software and a first point of time when a size of an updated portion of the software reaches a predetermined size,

obtain an estimated first length of time between the point of time of starting the update of the software and a point of time when the size of the updated portion of the software reaches the predetermined size, based on the estimated length of time and the predetermined size,

obtain a difference between the estimated first length of time and the measured first length of time, and

when the difference is more than a predetermined value, calculate a first length of remaining time to be taken to complete the update of the software, based on the measured first length of time and the predetermined size; and

an output device configured to provide an output corresponding to the calculated first length of remaining time.

15. The terminal device of claim 14 , wherein

the processor is further configured to:

determine whether the update of the software is completed, and

if the update of the software is determined as not being completed, change the predetermined size to an other size,

obtain a measured second length of time between the point of time of starting the update of the software and a second point of time when the size of the updated portion in the software reaches the other size, and

calculate a second length of remaining time to be taken to complete the update of the software, based on the measured second length of time and the other size, and

the output device is further configured to provide an output corresponding to the calculated second length of remaining time.

16. The terminal device of claim 14 , wherein

the processor is further configured to obtain a length of remaining time to be taken to complete the update of the software, based on the predetermined size and the obtained total length of time, when the difference is equal to or less than the predetermined value, and

the output device is further configured to provide an output corresponding to the obtained length of remaining time.

17. A method implemented by a terminal device, comprising:

receiving, from a server via a network, a file for updating software stored in a memory device coupled with the terminal device, and a software update table wherein the software update table includes data regarding one or more performance values and data regarding one or more time values indicative of one or more lengths of time taken to update the software using the file, respectively, and each of the one or more performance values is associated with one of the one or more time values;

obtaining data regarding a performance value of the memory device;

selecting, from the software update table, one of the one or more performance values based on the performance value of the memory device;

obtaining, from the software update table, a time value associated with the selected performance value; and

providing an output corresponding to the obtained time value at an output device of the terminal device.

18. A method implemented by a terminal device, comprising:

obtaining, from a server via a network, an estimated total length of time to be taken for an update of software stored in a memory device coupled with the terminal device;

obtaining a measured first length of time between a point of time of starting the update of the software and a first point of time when a size of an updated portion of the software reaches a predetermined size;
