Answer: 3D TV is an emerging technology that allows consumers to enjoy three-dimensional movies, television programs and video games in their homes. Several companies have developed viable 3D technology for the home theater environment, but the reality of seeing 3D TV in the average household is probably years away. That's primarily because the technology requires the purchase of new television equipment, including a 3D-ready TV and a 3D-capable Blu-ray player.

Packet switching Packet switching is a digital networking communications method that groups all transmitted data – regardless of content, type, or structure – into suitably sized blocks, called packets. Overview[edit] An animation demonstrating data packet switching across a network (Click on the image to load the animation) Packet switching features delivery of variable bitrate data streams (sequences of packets) over a computer network which allocates transmission resources as needed using statistical multiplexing or dynamic bandwidth allocation techniques. Rawlemon’s Spherical Solar Energy-Generating Globes Can Even Harvest Energy from Moonlight The solar energy designers at Rawlemon have created a spherical, sun-tracking glass globe that is able to concentrate sunlight (and moonlight) up to 10,000 times. The company claims that its ß.torics system is 35% more efficient than traditional dual-axis photovoltaic designs, and the fully rotational, weatherproof sphere is even capable of harvesting electricity from moonlight. The ß.torics system was invented by Barcelona-based German Architect André Broessel.

HP Servers <a href=" of site-wide JavaScript functionality</a> Jump to content United States-English HP.com home HP Servers Router and Switch Security Overview Router and Switch Security Overview "You are only as secure as your weakest link." Network security professionals often encounter this adage. Present-day networks deploy security measures such as firewalls, intrusion detection systems (IDS), virtual private networks (VPN), and antivirus software to fortify the network. Unfortunately, the most basic network elements—routers and switches—are often ignored as security devices because routers and switches were originally created to enhance network connectivity rather than to provide network security. Consequently, routers and switches are conceptually less secure than dedicated security devices such as firewalls and IDSs.

Domain Name System The Domain Name System (DNS) is a hierarchical distributed naming system for computers, services, or any resource connected to the Internet or a private network. It associates various information with domain names assigned to each of the participating entities. Most prominently, it translates domain names, which can be easily memorized by humans, to the numerical IP addresses needed for the purpose of computer services and devices worldwide. The Domain Name System is an essential component of the functionality of most Internet services because it is the Internet's primary directory service. The Domain Name System distributes the responsibility of assigning domain names and mapping those names to IP addresses by designating authoritative name servers for each domain. Authoritative name servers are assigned to be responsible for their supported domains, and may delegate authority over sub-domains to other name servers.
