WEB 3.0 revolutioning

Basic Theme

Web 3 is web based new technology which is being developed, The technology provide a growth in the improving the intelligence of web browser, Web 3 making your web browser as your personnel assistant. For example if you have a plan to see a movie and to have some Chinese food, Then you just browse your browser open google and type your query of watching movie and having food, the browser automatically by your choice found the movie and list of restaurant, This is what more smart your search become.

Intro to WEB 2.0 and WEB 1.0

Most of you visit the YOUTUBE, this site is based on the web2.0 technology,here you can upload your video personalized your home page, IGOOGLE is also based on web2.0.
many websites like AMAZON.com uses web2.0 technology


web1.0 is mere gives the information the user cannot interact in this with site or cannot make changes to the site.

Web 3.0

Internet experts think Web 3.0 is going to be like having a personal assistant who knows practically everything about you and can access all the information on the Internet to answer any question. Many compare Web 3.0 to a giant database. While Web 2.0 uses the Internet to make connections between people, Web 3.0 will use the Internet to make connections with information. Some experts see Web 3.0 replacing the current Web while others believe it will exist as a separate network

It's easier to get the concept with an example. Let's say that you're thinking about going on a vacation. You want to go someplace warm and tropical. You have set aside a budget of $3,000 for your trip. You want a nice place to stay, but you don't want it to take up too much of your budget. You also want a good deal on a flight.

With the Web technology currently available to you, you'd have to do a lot of research to find the best vacation options. You'd need to research potential destinations and decide which one is right for you. You might visit two or three discount travel sites and compare rates for flights and hotel rooms. You'd spend a lot of your time looking through results on various search engine pages. The entire process could take several hours.

According to some Internet experts, with Web 3.0 you'll be able to sit back and let the Internet do all the work for you. You could use a search service and narrow the parameters of your search. The browser program then gathers, analyzes and presents the data to you in a way that makes comparison a snap. It can do this because Web 3.0 will be able to understand information on the Web.

Right now, when you use a Web search engine, the engine isn't able to really understand your search. It looks for Web pages that contain the keywords found in your search terms. The search engine can't tell if the Web page is actually relevant for your search. It can only tell that the keyword appears on the Web page. For example, if you searched for the term "Saturn" you'd end up with results for Web pages about the planet and others about the car manufacturer.

A Web 3.0 search engine could find not only the keywords in your search, but also interpret the context of your request. It would return relevant results and suggest other content related to your search terms. In our vacation example, if you typed "tropical vacation destinations under $3,000" as a search request, the Web 3.0 browser might include a list of fun activities or great restaurants related to the search results. It would treat the entire Internet as a massive database of information available for any query.

CLOUD COMPUTING~~

Cloud computing means Internet('Cloud') based development and use of computer technology ('Computing'). It is a style of computing where IT-related capabilities are provided “as a service”[1] allowing users to access technology-enabled services without knowledge of, expertise with, or control over the technology infrastructure that supports them. It is a general concept that incorporates software as a service, Web 2.0 and other recent, well-known technology trends.

The majority of cloud computing infrastructure currently consists of reliable services delivered through next-generation data centers that are built on compute and storage virtualization technologies. The services are accessible anywhere in the world, with The Cloud appearing as a single point of access for all the computing needs of consumers. Commercial offerings need to meet the quality of service requirements of customers and typically offer service level agreements. Open standards and open source software are also critical to the growth of cloud computing.

Apple iPhone 3G challenger: LG Dare from Verizon

Verizon Wireless has launched yet another Smartphone to take on the upcoming Apple iPhone 3G from AT&T.

The company has launched the LG Dare which is a touchscreen Smartphone.

LG Dare comes with a 3-inch LCD touchscreen featuring a proximity sensor that turns off the LCD when it’s close to a user’s face.

It also features an accelerometer (similar to the Apple iPhone) which changes the orientation of the display based on how it is held.

The phone also features tactile feedback and handwriting recognition.
LG has loaded this mobile device with a 3.2-megapixel camera with a Schneider-Kreuznach certified lens. It also features LED flash and face-detecting technology.

Dell Studio 15 and Dell Studio 17 launched

US based personal computer maker Dell has launched their latest range of personal computers.

This new range is named Dell Studio and these are designed to offer personalized high definition mobile experience.

The company has launched two products under this new range: Dell Studio 15 and Dell Studio 17.

Dell is offering a variety of customizable options on these two laptops. Michael Tatelman, vice president of Dell consumer sales and marketing worldwide spoke about these new products: “These products are built for today’s digital nomad based on the millions of conversations we have every year on dell.com, Ideastorm and community forums. With Dell Studio we’re answering the call for personalization, connectivity and simplicity.”

storing device in computers

Computer data storage, often called storage or memory, refers to computer components, devices, and recording media that retain digital data used for computing for some interval of time.
Usually the memory is consider of semiconductor storage known as random access memory(RAM),these are the primary storage memory but use for temporary storage,But the permanent storage for data is also required these can be gain through optical disk,magnetic disk like hard disk .

Hierarchy of storage

1 Primary storage
2 Secondary storage
3 Tertiary storage
4 Off-line storage

Primary storage
Primary storage, presently known as memory, is the only one directly accessible to the CPU. The CPU continuously reads instructions stored there and executes them.
The invention of transistor makes new technology development in the storing capability. This led to a modern random access memory (RAM). It is small-sized, light, but quite expensive at the same time. (The particular types of RAM used for primary storage are also volatile, i.e. they lose the information when not powered).

Beside of RAM their is two other type of memory also-:

a)Register memory-

Processor registers are located inside the processor. Each register typically holds a word of data (often 32 or 64 bits). Registers are technically among the fastest of all forms of computer data storage, being switching transistors integrated on the CPU's chip, and functioning as electronic "flip-flops".

b)cache memory-

Processor cache is an intermediate stage between ultra-fast registers and much slower main memory. It's introduced solely to increase performance of the computer. Most actively used information in the main memory is just duplicated in the cache memory, which is faster, but of much lesser capacity. Multi-level hierarchical cache setup is also commonly used—primary cache being smallest, fastest and located inside the processor; secondary cache being somewhat larger and slower.
Main memory is directly or indirectly connected to the CPU via a memory bus.
As the RAM types used for primary storage are volatile (cleared at start up), a computer containing only such storage would not have a source to read instructions from, in order to start the computer. Hence, non-volatile primary storage containing a small startup program (BIOS) is used to bootstrap the computer, that is, to read a larger program from non-volatile secondary storage to RAM and start to execute it. A non-volatile technology used for this purpose is called ROM, for read-only memory (the terminology may be somewhat confusing as most ROM types are also capable of random access).

Secondary storage
Secondary storage, or storage in popular usage, differs from primary storage in that it is not directly accessible by the CPU. The computer usually uses its input/output channels to access secondary storage and transfers desired data using intermediate area in primary storage. Secondary storage does not lose the data when the device is powered down—it is non-volatile.

Hard disks are usually used as secondary storage.
The secondary storage is often formatted according to a filesystem format, which provides the abstraction necessary to organize data into files and directories, providing also additional information (called metadata) describing the owner of a certain file, the access time, the access permissions, and other information.
Most computer operating systems use the concept of virtual memory, allowing utilization of more primary storage capacity than is physically available in the system. As the primary memory fills up, the system moves the least-used chunks (pages) to secondary storage devices (to a swap file or page file), retrieving them later when they are needed. As more of these retrievals from slower secondary storage are necessary, the more the overall system performance is degraded.

Tertiary storage
Tertiary storage or tertiary memory,[2] provides a third level of storage. Typically it involves a robotic mechanism which will mount (insert) and dismount removable mass storage media into a storage device according to the system's demands; this data is often copied to secondary storage before use. It is primarily used for archival of rarely accessed information since it is much slower than secondary storage (e.g. 5-60 seconds vs. 1-10 milliseconds). This is primarily useful for extraordinarily large data stores, accessed without human operators. Typical examples include tape libraries and optical jukeboxes.

Off-line storage
Off-line storage, also known as disconnected storage, is a computer data storage on a medium or a device that is not under the control of a processing unit.[3] The medium is recorded, usually in a secondary or tertiary storage device, and then physically removed or disconnected. It must be inserted or connected by a human operator before a computer can access it again. Unlike tertiary storage, it cannot be accessed without human interaction.

Iphone going to 3G

steve jobs the ceo of Apple with tag line 'think different' has come again with his new technology, 3G Iphone in market.In india vodaphone is lanching 3G Iphone.

That Apple will eventually come up with a 3G iPhone is inevitable; one may recall Apple Chief Steve Jobs alluding to that when he first introduced the device in January 2007. If the current iPhone offers only 2.5G (EDGE) speeds, it's got everything to do with excessive power consumption from 3G chipsets. Then again, with some newly-announced 3G chipsets that look like they'll solve some of these problems, the 3G iPhone may become a reality sooner than expected. In fact last year, AT&T, Apple's official carrier partner for the iPhone in the US, had said that it expects being able to sell a 3G version of iPhone in 2008, offering no specific details beyond that.
Scott Craig has predicted that Apple would have produced as many as 8 million 3G iPhones in the third quarter of this year. Previously, Craig had estimated that Apple would make 8 million such devices in the whole of 2008. Meanwhile, a Taiwanese publication that goes by the name 'Commercial Times' has reported that bidding for the 3G iPhone manufacturing contract is already underway. Elsewhere, it is reported that Hon Hai has won the contract for manufacturing Apple's 3G iPhones.
