What is the difference between a persistent object and a transient object?
a persitent object is the one that is stored permanently on the disk......whereas a transient object is stored temporarily on the ram....
Can transient variables be declared as 'final' or 'static'?
Transient Variables are those that do not get serialized during the Serialization process. A Static variable is one that is mapped to the Class and is not mapped to any object instance and hence they would not get serialized. So, there should be no problem with declaring a transient variable as static. On the other hand, A final variable is one that's value cannot change. So if you declare a final variable as transient, it would get stored as null during serialization and when you try to de-serialize the variable, you will get errors because, the variable is final and you cannot assign values for it and it is saved as null during serialization. Result: Yes you can have static transient variables but not final transient variables.

How are string stored in c language?
Strings represented by the language character set (e.g., ASCII) are stored as null-terminated arrays of type char. Wide-character strings are stored as null-terminated arrays of type wchar_t. Other types are also available, such as char16 and char32 (for UTF16 and UTF32 encodings, respectively).

Is electric charge a tiny amount of energy?
Depends on the amount of the electric charge and on which place it is stored. Two clouds with a big amount of a potential electric charge, one positive and the other negative, will produce a huge amount of energy represented by a lightning bolt.
Give three example of transient evidence and explain why it may be transient?
Temporary internet files: These are files stored by web browsers while accessing websites. They are transient because they are often automatically deleted after a period of time to free up storage space. Volatile memory (RAM) data: Information stored in RAM is transient because it is lost when the computer is powered off. It is used for temporary storage of data that is actively being accessed or processed. Logs generated by applications: These logs record events and activities performed by applications. They are transient as they are often overwritten or deleted after a certain period to manage disk space and maintain system performance.
Can the electrostatic charge be stored?
It's always stored unless it's conducted away. Thus all insulators have & hold a static charge.

A track on a disk is what?
data are stored on a circular tracks the 0s and 1s are represented magnetically
What is stored charge?
In a capacitor it is a build up of electrons on a plate.

Can the solar energy stored and used when required?
Yes, it can be used to charge batteries. The energy in the battery can be stored for later use.
Is electric current stored anywhere?
Electric current is the movement of charge around a circuit and so cannot really be stored, however, the energy which it carries is stored in most things.
Step recovery diode construction and its working?
The step recovery diode is used as what is termed a charge controlled switch. When the step recovery diode is forward biased and charge enters it, the diode appears as a normal diode and it behaves in much the same way. When diodes switch from forward conduction to reverse cut-off, a reverse current flows briefly as stored charge is removed. When all the charge is removed it suddenly turns off or snaps off. It is the abruptness with which the reverse current ceases that enables the step recovery diode to be used for the generation of microwave pulses and also for waveform shaping. To explain this in more detail, under normal forward bias conditions the diode will conduct normally. Then if it is quickly reverse biased it will initially appear as a low impedance, typically less than an ohm. Once the charge that is stored in the device is depleted, the impedance will very abruptly increase to its normal reverse impedance which will be very high. This transition occurs very quickly, typically well under a nanosecond. This property allows the step recovery diode to be used in pulse shaping (sharpening) and in pulse generator circuits. The high harmonic content of the signal produced by any repetitive waveforms from step recovery diode circuits enables them to be used as comb generators where a comb of harmonically related frequencies are generated.
