Sleep Mode
A power mode that enables computers to save power consumption
when they are not being used. When a computer is in Sleep Mode,
the data on the computer memory is not saved to the hard disk. If

System File

operating system. In general, system files must not be deleted or
moved.
TCP/IPv4
This is a 4 byte (32 bit) address system separated into each byte
(8 bits) by a dot and each byte is represented as a decimal number.
USB
(Universal Serial Bus)
This refers to a serial interface standard developed to replace the
conventional interface standards such as Serial and PS/2. While USB
1.1 supports 12Mbps (12 million bits per second), USB 2.0 supports
a data rate that is 40 times (480Mpbs) faster than that of USB 1.1.
The data rate of USB 2.0 is equivalent to that of IEEE1394. Therefore
USB 2.0 is used for A/V devices supported by IEEE 1394 and a 2nd
HDD and CDRW that require a high data rate.
Virtual XP Mode
This is a virtual operating system that enables running Windows XP
programs on the Windows 7 operating system. Using this mode,
you can run programs that do not run on Windows 7.
Windows Media Player
A multimedia program included with Windows. Using this
program, you can play a media file, create an audio CD, listen to a
radio broadcast, search and manage media files, and copy files to a
