What is the bandwidth of DSBSC?
BW=2 fm
Draw the waveform of AM signal and DSBSC signal?
Draw thewaveform of AM signal and DSBSV
Explain why interrupts are not appropriate for implementing synchronization?
Because they are completely unrelated things? Synchronization can be implemented with semaphores or mutexes.
How does thread synchronization occur in a monitor?
by using synchronized class
What is the work of atomic clocks in space vehicle?
For synchronization with ground assets
Synchronization in operating system?
Synchronization in an operating system refers to the coordination of the events in order to operate a given operating system.
What do you mean by synchronization in operating system?
synchronization mean arrange all process in sequence for that not occured no colusion in the system.
What is internal synchronization in distributed system?
Internal synchronization in a distributed system refers to the mechanism through which processes or nodes coordinate their actions to ensure consistency and order in the system. This can involve using techniques like mutual exclusion, barriers, or message ordering to manage concurrent access to shared resources and maintain data integrity across the distributed environment. Internal synchronization helps prevent race conditions and ensures that operations are carried out in a predictable and controlled manner.
What is the bandwidth of DSBSC?
BW=2 fm
What has the author Umberto Mengali written?
Umberto Mengali has written: 'Synchronization techniques for digital receivers' -- subject(s): Digital communications, Equipment and supplies, Synchronization, Timing circuits, Design and construction
Draw the waveform of AM signal and DSBSC signal?
Draw thewaveform of AM signal and DSBSV
What is interprocess synchronization?
Processes might need to communicate to each. Interprocess of synchronization is the?æ management of resource among process. It ensures only a single thread (process) access a resource at a particular time.
Which type of system attack sends a flood of TCP synchronization requests to a host?
SYN flood
What type of system attack sends a flood of TCP synchronization requests to a host?
SYN flood
Techniques of strategic control?
Different techniques
What component of the hydraulic system is used to obtain the synchronization pressure?
cam right angle drive needle valve
How clock synchronization occurs in a distributed system?
Clock synchronization in a distributed system is achieved by using algorithms like NTP (Network Time Protocol) or PTP (Precision Time Protocol) to ensure that all clocks in the system are adjusted to a common time reference. This helps in maintaining consistency and coordination among different nodes in the distributed system. By periodically updating and correcting the local clocks based on a reliable time source, synchronization is maintained across the system.
