i have received iit jee 2008 rank 5872 and ob rank 818 . if any one can tell me which branch and iits should I opt for to get a good use of my options

Asked by rahul in Computers & Technology at 11:15 AM on June 04, 2008

Sudipta Deb's Answer

Since your rank is not that much good, I will prefer you for first search for IIT and the search for any specific subjects. Getting into IIT is more important rather than choosing your subject for you right now.

In order to decode dolby sounds it is required to have a dolby decoding sound card in your system. But right now almost every computer comes with sound card and that sound card is being capable to decode the dolby sounds.

How can I keep the LCD monitor of my computer clean ?

Asked by souravbasu in Computers & Technology at 6:48 AM on May 05, 2008

Sudipta Deb's Answer

If that wonderfully sleek, space-saving flat-screen monitor adorning the top of your desk or workstation is blurry with fingerprints and smudges, there is hope. LCD (liquid crystal display) screens are especially susceptible to scratches and require a little special care, but you can have yours shining like new in no time. Apparently, every manufacturer has their own recommendations on how to best clean their particular model of LCD, but there are some general guidelines.
You don't have to turn the monitor off before cleaning it, but this will help you see the smudges and smears. If your screen is merely dusty, you can wipe gently with a soft, cotton cloth or try a can of compressed air. But if your screen is downright grungy, you might have to resort to some tougher tactics.

Though some people recommend using Windex, ethyl alcohol and ammonia-based cleaners can yellow your flat-screen or laptop monitor over time, so it is best to avoid such products. You can find an array of commercial products specifically designed to clean LCD screens, but you may prefer to just head to your kitchen and mix up your own solution. Plain old water can do the trick, or you can concoct a solution of vinegar and water or isopropyl alcohol and water.

Always use a soft cotton cloth, rather than a rag or paper towel to wipe the screen. Some people recommend special electrostatic cloths, like those used to clean eyeglasses treated with anti-glare finish, or even dryer sheets. Apply the cleaning solution to your cloth rather than directly to the screen and wipe in one direction -- from the top of the screen to the bottom.

One final word of warning, never touch or press on your LCD screen with your fingers as this can cause the pixels to burn out.

how can a locked micro SD memory card b unlocked? since i forgot my password of my memory card n its not even formatting..?

Asked by prem sharma in Computers & Technology at 9:01 AM on May 07, 2008

Sudipta Deb's Answer

For S60 1st and 2nd Phones

What should we do if we forget the password? For S60 1st and some of 2nd phones, such as Nokia 3650, Nokia 6600 and Nokia N-Gage, the password is stored in a plain text file.

* Firstly, you need to install FExplorer, a free file manager that allows us to browser through S60 file system.
* Next, launch FExplorer and then browser to c:\system folder. There is a file, called mmcstore.
* Rename the file to mmcstore.txt and then open it. Your password must be several characters at the end of the file.

For S60 3rd Phones, Nokia N-Series and Nokia E-Series

Unfortunately, there is no way to recover the password in the latest S60 phones. The only way that I know so far is by reformatting the memory card. It can be done from Memory Card application by selecting Options | Format memory card menu. Of course, you will lose all your data in the memory card… :(

If any of you have experience unlocking password of memory card in latest S60 phones, feel free to share it here.

Compatible devices: S60 1st, 2nd, 3rd Edition, Nokia Nseries, Nokia Eseries.

what are the software quality features of component based sofware engineering

Asked by harsha in Computers & Technology at 5:46 PM on May 08, 2008

Sudipta Deb's Answer

A software component is a system element offering a predefined service or event, and able to communicate with other components. Clemens Szyperski and David Messerschmitt give the following five criteria for what a software component shall be to fulfill the definition:

* Multiple-use
* Non-context-specific
* Composable with other components
* Encapsulated i.e., non-investigable through its interfaces
* A unit of independent deployment and versioning

A simpler definition can be: A component is an object written to a specification. It does not matter what the specification is: COM, Enterprise JavaBeans, etc., as long as the object adheres to the specification. It is only by adhering to the specification that the object becomes a component and gains features such as reusability.

Software components often take the form of objects or collections of objects (from object-oriented programming), in some binary or textual form, adhering to some interface description language (IDL) so that the component may exist autonomously from other components in a computer.

When a component is to be accessed or shared across execution contexts or network links, techniques such as serialization or marshalling are often employed to deliver the component to its destination.

Reusability is an important characteristic of a high quality software component. A software component should be designed and implemented so that it can be reused in many different programs.

In the 1960s, scientific subroutine libraries were built that were reusable in a broad array of engineering and scientific applications. Though these subroutine libraries reused well-defined algorithms in an effective manner, they had a limited domain of application. Today, modern reusable components encapsulate both data structures and the algorithms that are applied to the data structures.

Software components are built using a programming language that has a limited vocabulary, an explicit defined grammar and well-defined rules of syntax and semantics. At the lowest level, the language mirrors the instruction set of the hardware. At the mid level, a programming language such as C or Smalltalk is used to create a procedural description of the program. And at the highest level, the language uses graphical icons or other symbology to represent the requirement for a solution. Here executable instructions are automatically generated.

When a good software developer produces a maintainable, well documented program, machine level language can make extremely efficient use of memory and "optimize" program execution speed. But mid level language allow software developer and the program to be machine independent. These are procedural languages. In non procedural language, a program by specifying the desired result is required to achieve the result. Support software translates the specification results into a machine executable code.

It builds on prior theories of software objects, software architectures, software frameworks and software design patterns, and the extensive theory of object-oriented programming and the object oriented design of all these. It claims that software components, like the idea of hardware components, used for example in telecommunications, can ultimately be made interchangeable and reliable.

what is future of mobile ..? what is next gen phone.

Asked by mahesh kawle in Computers & Technology at 1:48 PM on March 28, 2008

Sudipta Deb's Answer

Hi Mahesh, I think what all of the web-platform proponents are missing is that these are only really good for webby sorts of things. Google reader is good for reading news on the internet, so it doesn't matter that you have to be hooked up to an internet connection to use it. Likewise posting photos on the internet, or watching youtube: both internet activities that we accept we need a connection to use.

But when you want to find a contacts address or check your calendar, you don't want to be firing up an internet connection every time. Smartphones have exceeded their initial brief: to provide additional services while on a phone. People now want to use them outside of phone coverage and usage patterns. But the web only goes so far in giving us useful applications - sometimes we want to be off the grid.

Sudipta Deb's Answer

Hey i am an IT professional, so what i will suggest you is that go for MCA. All the Indian big gaint companies like Wipro, TCS, CTS, Infosys are always looking for MCA rather than GNIIT. The reason is that they always prefer government certified professionals rather than from some private institute.
