Cisco Linksys – Smart Wi-Fi Routers

Smart Wi-Fi routers are the trending technology because we are moving from traditional Wired Communication to Wireless communication and because of the advantages in Wireless communications- many organizations are trying to make the most use of it and integrate all such features which might make the user feel more comfortable.

Smart Wi-Fi – the name says it all, it has several other capabilities from just being a Wireless Router to connect to various Devices. The routers offer new tools for home network monitoring and control, and new mobile apps for anytime, anywhere remote access of files, photos, videos, music and more.

Easier Management and Setup

To make home networks easier for consumers to monitor and control, Linksys is also introducing a smart network map, a new Smart Wi-Fi tool that will be free for new Linksys Smart Wi-Fi Routers. The smart network map displays a visual representation of the home network and all of the connected devices to give users valuable information about network connectivity and current bandwidth usage so they can easily control devices, resolve issues, and get the most out of their home network.

To further simplify setup, Linksys’ new Smart Wi-Fi Routers can be installed from most tablets and smartphones or from a browser on a PC, without the need for a setup CD. Consumers simply connect to the router with their computer, tablet or smartphone, and then follow the simple set-up wizard to complete the installation. An optional Linksys Smart Wi-Fi account can be created following the set-up process to provide easy control of the home network, including settings, connected devices and Smart Wi-Fi tools on virtually any device, anytime, anywhere.

Simple Tap with NFC capability

To simplify connecting devices to the network, SimpleTap™ is now available with all Linksys Smart Wi-Fi Routers. SimpleTap simplifies the process of connecting devices to a home network, making it as easy as one touch of a button or a quick tap of a card. With SimpleTap, users can take advantage of Wi-Fi Protected Setup (WPS) in a number of ways such as using the NFC card shipping with all 802.11ac enabled Smart Wi-Fi routers, pushing the physical WPS button on a router or pushing the WPS button in the router’s browser or app interface.

Linksys Smart Wi-Fi Apps

Among the apps coming for Linksys Smart Wi-Fi are a several that will take advantage of the platform’s new ability to remotely access storage connected to the router. Four of the apps using this new capability are expected to be available in the spring.

App name Developer Description
FileFinch Fresh Consulting FileFinch helps users create a personal, highly secure cloud solution using their own hardware. Users simply connect a USB flash drive or hard disk to a Linksys Smart Wi-Fi Router and click to link their account. They can then access their files anywhere.

De-Militarized zone (DMZ)

Every corporate office has a official public website which can be accessed by every individual using public internet. Data related to this site has to be stored in servers and the location of these servers is a challenge! The challenge is servers have to be accessible by the public users but they should not disturb the internal network of the organization in other words an attacker from internet should not be able to reach the internal network through these servers. Then came the concept of DMZ. It is a zone that lies between an organization’s internal network and an external network, usually the Internet

Concept of DMZ :

      In military terms, a De-Militarized zone (DMZ) is an area, usually the frontier or boundary between two or more military powers (or alliances), where military activity is not permitted, usually by peace treaty or other bilateral or multilateral agreement

In a computer network apart from the Internet and Intranet there exists De-militarized zone which has the security protection level lying in between the Intranet and the Internet. The Intranet is a High security zone where the internal host systems, servers etc., of an organization are present and which are to be secured from the attacks or threats. Internet is an outside public network which is considered as a low security zone.

Traffic flow in DMZ installed networks:

  • Internal hosts can access DMZ and internet.
  • External hosts can access only DMZ not the intranet.
  • DMZ hosts can access internet only.

The amazing world of Google’s data centres

Google is opening a virtual window into the secretive data centres that serve as its nerve centre. The closely guarded facilities house an intricate maze of computers that process

Facebook remakes the server

Facebook showed  working prototype of Open Rack, an energy efficient server that’s intended to power data centers which can theoretically scale to more than 100,000 physical machines.

OpenRack is very much a work in progress. The current rack uses Facebook’s third and so-far most compact generation of a two-socket x86 server. Engineers here already envision a fourth generation that shrinks the server design  yet again. Ideally, the board would contain only processors and a PCI Express fabric, no Ethernet or other components—but that will require a variant of Express that is only on the drawing board today.

  • Each OpenVault tray has control electronics on a slide-out board. In future, the board could host an ARM-based controller to handle special storage functions. Facebook believes such an application could become its first use of an ARM SoC.
  • Specifically, they expect to move from 250-500 Gbyte hard drives—the smallest they can now get—to 128 Gbyte  serial ATA SSDs which have enough capacity and might even be cheaper.

Computer scientists have developed a technique to automatically allow one computer in a virtual network to monitor another for intrusions, viruses or anything else that could cause a computer to malfunction.

The technique has been dubbed “space travel” because it sends computer data to a world outside its home, and bridges the gap between computer hardware and software systems.

“Space travel might change the daily practice for many services offered virtually for cloud providers and data centers today, and as this technology becomes more popular in a few years, for the user at home on their desktop,” said Dr. Zhiquian Lin, the research team’s leader and an assistant professor of computer science in the Erik Jonsson School of Engineering and Computer Science.

As cloud computing is becoming more popular, new techniques to protect the systems must be developed. Since this type of computing is Internet-based, skilled computer specialists can control the main part of the system virtually — using software to emulate hardware.

Lin and his team programmed space travel to use existing code to gather information in a computer’s memory and automatically transfer it to a secure virtual machine — one that is isolated and protected from outside interference.

“You have an exact copy of the operating system of the computer inside the secure virtual machine that a hacker can’t compromise,” Lin said. “Using this machine, then the user or antivirus software can understand what’s happening with the space traveled computer setting off red flags if there is any intrusion.

Previously, software developer had to manually write such tools.

“With our technique, the tools already being used on the computer become part of the defense process,” he said.

The gap between virtualized computer hardware and software operating on top of it was first characterized by Drs. Peter Chen and Brian Noble, faculty members from the University of Michigan.

CYMATICS

If  we could see sound  our world would be even more beautiful than we could imagine. It would be a world filled with shimmering holographic bubbles each displaying a kaleidoscopic pattern on its surface. To see sound is to open a new window onto our world, one that has been veiled in mystery until recently.

A sound bubble created by a violin sound…
