Some iconic shows like "Eureka", and movies like "Smart House", have touched upon the idea of a futuristic house that can interact with its occupants. Though we may not be there yet, we seemed to have developed a house that can literally meet its own energy requirements, and then some. Imagine a house that can not only meet its own power requirements, but actually create a surplus of energy, effectively turning it into a small power plant. Well, you don't have to imagine it anymore. Thanks to the innovative thinking of Neumann Developments, we have reached a new error for mankind. They have not only designed a house that meets its own power requirements, they built it. They have even supplied it...

In the past, when two persons were willing to share data between each other, they were relying on movable disks such as floppy disks and CD-ROM. These ways of transmitting data between remote computers are often difficult especially if the files will be transmitted very often. Because of the above difficulties in transmitting data across movable disks, the idea of networking two or more computer has been arisen. Instead of transmitting the files across movable disks, the computers are connected to each other by cables through ports on the computer. When someone needs to transmit the data to another computer, he simply can share the files he needs to transmit across the network. This way no movable...

When you are putting together a data centre, everything has to be connected together; most good data centres will have enough data flowing to completely overwhelm a typical wireless router, and wired data speeds are always faster than wireless, hence the emphasis on cable runs. Planning how your networking topology will run is a large part in setting up your data centre. You need to set space for the cables to be run, and it helps to know what kind of cable you plan on using. The lowest grade of twisted pair cable is plain old telephone cable, such as is used to hook up your phone to the wall socket; this has serious bandwidth issues, and the signal drops off rapidly over time. In terms of the...

A confidentiality attack tries to capture confidential data (such as username, password, credit card numbers and data in emails) so an attacker can use that data for malicious intent. Confidentiality attacks often go undetected because the attacker makes a copy of the data, rather than trying to change the data or take down the system. There are several different types or methods to a confidentiality attack: Packet Capture: A packet capture utility can capture data that is sent across the network or from a PC's NIC card. The packets can contain username and password, credit card numbers, social security card numbers or anything that is in plain text. An attacker can read this data from a packet...
