Alarm systems come in two basic forms. Wireless & wired. A system that is "hardwired" is simply a wired system. A home that has been prewired for an alarm means that the hardwire has already been run, generally when the home is initially constructed.

no u must use an ethernet cable or wireless internet For most people who do not have a wireless connection in their home they must also purchase at least a router to allow a connection between the cable modem and the PS3. An ethernet cable allows a wired connection between the PS3 and the router and if running a cable is a problem you need to purchase a wireless router. Although I purchased a wireless router I found that the wired connection worked better and the wireless router also had four wired connection spots on the back.
The use of cables for the internet is very simple. The cable provides the connection between an internet connection and a computer. Nowadays, wireless connection is more common.
A router is a device that connects to your modem to share your internet connection with other computers. A wireless router uses a power cord and an Ethernet cable to connect from the modem to the router without the need of a connection between the router and the computers it's sharing the Internet connection with. A USB wireless router connects to the modem using a single USB connection that serves as both the power supply and data connection.
