What is an Adapter??

As we all heard of Adapter many times, it can be a TV adapter, Telephone Adapter, Adapter for speakers etc., Adapters are used very commonly in many of the Electronic devices. They play a key role in the Electronic Consumer Industry.

ADAPTER: An adapter is a physical device that allows one hardware or electronic interface to be adapted (accommodated without loss of function) to another hardware or electronic interface. In a computer, an adapter is often built into a card that can be inserted into a slot on the computer’s motherboard. The card adapts information that is exchanged between the computer’s microprocessor and the devices that the card supports.

Many times we forget to unplug the Battery Charger from the AC Power socket after detaching the Phone from the Charger, Power socket will be in ON position and we think that the current is being wasted as the Power socket is ON and as we have not connected any Mobile to it, current is being wasted.

But this is not exactly what it is happening, Lee me first give you a brief introduction to what LOAD means in an Electronic Circuits.

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

Intel Hyper Threading(HT) Technology

If you’ve thought about buying an Intel processor lately – or a computer with an Intel processor installed – you may have heard the term “Hyper-Threading” launched at your eardrums. You probably aren’t familiar with this term unless you stay up-to-date with the nitty-gritty of computer hardware.

Understanding Hyper-Threading is important, however, because it’s a major feature on some Intel processors. Like most major processor features, it can be twisted and turned by the sales reps you meet.Virtually Hyper-Threading effectively doubles the number of cores on a processor. Although true in a sense, it’s mostly an exaggeration.

Let’s take a look at what Hyper-Threading really means.

FUEL CELLS – A new Energy resource for the World

What exactly is a fuel cell, anyway? Why are governments, private businesses and academic institutions collaborating to develop and produce them? Fuel cells generate electrical power quietly and efficiently, without pollution. Unlike power sources that use fossil fuels, the by-products from an operating fuel cell are heat and water. But how does it do this?

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.

Pen Drive Vs Memory Card

Two major competitors in the battle for your memory-buying dollars are the memory stick(card) and the flash drive(pen drive). These two technologies are similar if not identical in many ways, but significant differences exist. While some of the differences are minor, some bear careful scrutiny before deciding which type of device is right for your application.

Nokia wants to create a mark in the market of Smartphones with its new range of phones LUMIA 920, 820 powered by WINDOWS 8 OS. However, did not reveal pricing or release dates for the new devices.

LUMIA 920

The Lumia 920 (left) features a 4.5-inch curved glass WXGA IPS LCD display that boasts what Nokia called PureMotion HD+, which the company said is “better than HD resolution.” That includes blur-free scrolling; “scroll through an email or webpage [and] the text stays crystal sharp.

Harlow claimed that the Lumia 920 is “the most innovative smartphone in the world.” She talked up Lumia 920’s camera, mapping technologies, and extra features like wireless charging. The device also support near-field communication (NFC).

DATA WIPING

Data Wiping is emerging as one of the most highly rated technologies in the field of Enterprise Level Storage. Let me take an example of a regular SATA hard disk which we use in our Home Desktops or Laptops, when we want to erase data we will directly format the hard disk so that the complete hard disk will become empty.
In some cases the hard disk itself crashes and we are bound to format it to use it again, but there are few Third party softwares which can be used to restore the data if the Disk crashes or even after the disk is completely formatted.This is beacuse of Data Remanence : Data remanence is the residual representation of data that remains even after attempts have been made to remove or erase the data.
