Lan & VLan ( Small Tips )

noreply@blogger.com (JayaKrishnan) — Wed, 01 Apr 2009 06:37:00 +0000

A local area network (LAN) is a computer network covering a small physical area, like a home, office, or small group of buildings, such as a school, or an airport. The defining characteristics of LANs, in contrast to wide-area networks (WANs), include their usually higher data-transfer rates, smaller geographic place, and lack of a need for leased telecommunication lines.

A virtual LAN, commonly known as a VLAN, is a group of hosts with a common set of requirements that communicate as if they were attached to the Broadcast domain, regardless of their physical location. A VLAN has the same attributes as a physical LAN, but it allows for end stations to be grouped together even if they are not located on the same network switch. Network reconfiguration can be done through software instead of physically relocating devices.

Internet to speed up by 60 times, claims research

noreply@blogger.com (JayaKrishnan) — Fri, 27 Mar 2009 19:16:00 +0000

Scientists at the University of Sydney have developed a switch that would allow the internet to become 60 times faster than current networks. Taking four years to complete, the switch is created using a small scratch on a piece of glass. The scratch will mean almost instantaneous error free access to the internet anywhere in the world, announced by Centre for Ultra-high bandwidth Devices for Optical Systems (CUDOS) at the Opto-Electronics and Communications Conference (OECC) held in Sydney.

"This is a critical building block and a fundamental advance on what is already out there. We are talking about networks that are potentially up to 100 times faster without costing the consumer any more," says Federation Fellow Professor Ben Eggleton, Director of CUDOS which is based within the School of Physics at the University of Sydney. The scratched glass is actually a photonic integrated circuit that has the capacity to increase the slow rate of information carried by optical fibres.

Using photonic technology that has terabit per second speed, the circuit uses the scratch as a guide or a switching path for information. Similar to when trains are switched from one track to another, this switch takes only one picosecond to change tracks. Therefore in one second the switch is turning on and off about one million times.

With the current prototype proving to achieve speeds 60 times faster than current Australian networks, the development team is confident that with further work the future of the technology looks promising. As we move towards faster and faster networking there will be ever higher demand for instant web gratification and photonic technology might be the way towards delivering those needs.

TFOT has previously covered P4P – next generation P2P, an advancement to file sharing technology. The system has the ability to make internet service providers (ISPs) and peer-to-peer (P2P) software providers work together in order to deliver data in a more efficient manner. TFOT also recently covered the world's smallest transistor, where graphene is carved into tiny electronic circuits with individual transistors not much larger than that of a molecule.

The Mars Ice FAQ: How Do You Know It's Water?

noreply@blogger.com (JayaKrishnan) — Sun, 22 Jun 2008 06:13:00 +0000

An interesting Blog from BLOGWIRED

The Wired Science blog has been flooded with comments and questions about yesterday's announcement that the Mars Phoenix Lander has observed ice on Mars. Some of these questions are so good that we can't let them go unanswered. So here's our Mars Ice FAQ. If you've got more questions, put them in the comments below!

How do you know it's water ice, not CO2 ice (aka 'dry ice')?

There is a lot of CO2 ice on Mars in the winter. However, Phoenix landed in the Martian arctic during the summer (because the lander is solar powered, the extra summer light is a necessity). In the Martian summer it is much too hot for dry ice to be solid. It would be like trying to keep water ice from melting on a 140-degree day here on Earth.

Carbon dioxide (CO2) will freeze on Mars at -125 C. Today's weather report from the Canadian weather station on Phoenix shows a low of -80 C -- way too hot for dry ice to stay solid right now. (Note the largest "pebbles" of ice were seen to stay solid for a day before disappearing).

Why not send instruments to detect life?

If you are going to make a claim like, "I have found life on Mars," you have to be prepared to show that there is NO chance your sample was contaminated with Earth bacteria before launch. To do that takes an incredible amount of sterilization. Don't worry -- they have already done a lot of sterilizing on the Mars Phoenix before launching it. But to really be sure they would have to go to extreme measures to be able to rule out any contamination, and doing that would have drastically increased the cost of the mission beyond its budget. So NASA and JPL plan missions that look for water and the conditions of life within the budgets they have now.

What about the bright white stuff in the sunshine?

The scientists said they are monitoring the bright patches in the sunshine for changes too. They are seeing some changes, but stay tuned for more explanation and details. As for how the "pebbles" that disappeared did so in the shade, one scientist did mention that the portion of the trench it was in was exposed to morning sunshine earlier in the day.

Why are the pictures not all in color?

Be patient. The first images sent out are the raw files from the lander. The science team is committed to getting us the images to us fresh off the presses, so they send out the raw (monochrome) images first. Typically if you wait a day, the team will release the image in full color once it has been processed (see above for full color version of yesterday's image).

How can water ice go straight from being a solid to being a gas (sublimation)?

Just like dry ice does here on Earth, water ice goes from solid to gas when the pressure is below 6.1 millibars and it gets heated (like it does in the Martian sun). It can also go straight from solid to gas above 6.1 millibars when the vapor pressure (amount of water vapor in the air) is low enough. This is because the molecules of water in solid form and gas form are not at equilibrium.

You might be surprised to know that the same thing happens here on Earth. If you have a frost-free freezer, you may have noticed that your ice cubes gradually shrink over a period of days. This is sublimation: the fan is constantly sucking water vapor out of the freezer so the ice cubes surrender more and more water molecules to the dry air over time.

The pressure on Mars is about 8 millibars, very close to the "triple point" of water, which is the point where it can easily exist as either a solid, a liquid or a gas (see the chart below). Since the vapor pressure is so low, water can easily sublime in the Martian atmosphere, especially as the surface heats up in the sunshine. When that happens, the soil can often get hotter than the air in the sunshine (think of a lizard sunbathing on a hot rock).
