No difference. There is a difference between obtain first and obtain next for an area sweep, but not when current on the owner in a set.

Recursive query can be create in SQL using stored procedure but you can also use CTE (Common table expression). It might be also worth asking about performance as CTE is not always very fast.

It is stored in the most significant bit. Bit is ON if -ve, OFF if +ve.

Managed execution process is a process where CLR executes the managed code. The steps involved in this process are:

1.  Choosing the right compiler


2.  Compiling the code to MSIL. This also generates the required metadata.


3.  Compile the MSIL ode to native machine code.


4. Executing the code with the variety of services available

TelephonyManager class can be used to get the IMEI number. It provides access to information about the telephony services on the device.

Data cleaning is also known as data scrubbing. Data cleaning is a process which ensures the set of data is correct and accurate. Data accuracy and consistency, data integration is checked during data cleaning. Data cleaning can be applied for a set of records or multiple sets of data which need to be merged.

Data cleaning is performed by reading all records in a set and verifying their accuracy. Typos and spelling errors are rectified. Mislabeled data if available is labeled and filed. Incomplete or missing entries are completed. Unrecoverable records are purged, for not to take space and inefficient operations.

JDK is Java Development Kit which is for development purpose and it includes execution environment also.

JVM is Java Virtual Machine which is a run time environment for the compiled java class files .Hence you will not be able to compile your source files using a JVM.
