What is synchronization and serialization?
Synchronization refers to multi-threading. A synchronized block of code can only be executed by one thread at a time. Serialization refers to converting objects to bitstreams either for storage or transmission. The act of serialization encodes the data according to specific rules.
What is the difference between paralleling and synchronization?
The process of matching parameters such as voltage, frequency, phase angle, phase sequence and waveform of alternator (generator) or other source with a healthy or running power system is called Synchronization of Generators. The process of synchronization is also called as Paralleling of Alternators or Generators.
What is the difference between Serializable and Parcelable?
Serializable is a standard Java interface. You simply mark a class Serializable by implementing the interface, and Java will automatically serialize it in certain situations. Parcelable is an Android specific interface where you implement the serialization yourself.
What is the difference between serialization and Deserialization?
Serialization is a mechanism of converting the state of an object into a byte stream. Deserialization is the reverse process where the byte stream is used to recreate the actual Java object in memory. This mechanism is used to persist the object.
What is synchronization and why is it important?
Synchronization control the access the multiple threads to a shared resources. Without synchronization of threads, one thread can modify a shared variable while another thread can update the same shared variable, which leads to significant errors.
What is synchronization and why use synchronization?
Synchronization is a process of handling resource accessibility by multiple thread requests. The main purpose of synchronization is to avoid thread interference. At times when more than one thread try to access a shared resource, we need to ensure that resource will be used by only one thread at a time.
What is meant by synchronization of generators?
In an alternating current electric power system, synchronization is the process of matching the frequency of a generator or other source to a running network. An AC generator cannot deliver power to an electrical grid unless it is running at the same frequency as the network.
What is synchronization panel for generator?
Synchronization panels are mainly designed and used to meet power system requirements. These panels function both manually and with an automatic synchronizing function for two or more generators or breakers. They are widely used in synchronizing generators and offering multiplex solutions.
Which is better Parcelable or Serializable?
Parcel able is faster than serializable. Parcel able is going to convert object to byte stream and pass the data between two activities. It doesn’t create more temp objects while passing the data between two activities. …
What is difference between Serializable and Parcelable which is better in Android and why?
In Parcelable, developers write custom code for marshaling and unmarshaling so it creates less garbage objects in comparison to Serialization. The performance of Parcelable over Serialization dramatically improves (around two times faster), because of this custom implementation.
What is the difference between marshalling and serialization?
Marshaling and serialization are loosely synonymous in the context of remote procedure call, but semantically different as a matter of intent. In particular, marshaling is about getting parameters from here to there, while serialization is about copying structured data to or from a primitive form such as a byte stream.
What is the process of generator synchronization?
Generator synchronization is the process of matching parameters such as voltage, frequency, phase angle, phase sequence, and waveform of alternator (generator) or other source with a healthy or running power system. This is done before the generator is reconnected to the power system.
What’s the difference between serialization and synchronization in Java?
Synchronization is a concurrency issue, e.g. how do you coordinate access to an object from multiple threads. Here an arrow represents access. Serialization is the conversion of data structures and objects into a sequence of bits that you can store/transmit and then convert back to data structures and objects.
What happens if you sync a generator with a power system?
If generator synchronization with a power system is done incorrectly or poorly executed, there is the potential for: Generator & prime mover damage due to mechanical stress caused by rapid accelerator/deceleration need to bring the rotating masses in synch. Damage to the generator and step-up transformer windows due to the high currents
When do you need to synchronize alternators in a generator?
The need for synchronization arrives, particularly when two or more alternators are working together to supply the power to the load. This is because electrical loads are not constant and they vary with time (depending on the load) and hence it is necessary to interconnect two or more alternators operating in parallel to supply larger loads.
