Glossary
•
3G: 3G refers to the 3rd-generation telecommunication technology which is the high speed transmission of the
cell data. The 3G service can transmit sound and other data simultaneously and the bitrate is up to hundreds kbps.
There are 4 standards for the 3G, the CDMA2000, WCDMA, TD-SCDMA, and WiMAX.
•
DHCP: DHCP is the acronym of Dynamic Host Configuration Protocol, and it is one of the TCP/IP protocol
stacks, it is used to assign the dynamic IP address to the host on the network.

falling and lifting. And those changes of the accelerated force can be sensed by the G-sensor in a means of
electrical signals, and then link certain action according to the changes of the electrical signals. When applied in
the hard disk protection, G-Sensor can check the current status of the hard disk in case of the affection of the R/W
function by the sudden change of the accelerated force.
