What is Thread starvation?

In a priority based scheduling, Threads with lower priority get lesser time for execution than higher priority threads.

If a lower priority thread performs a long running computation, it may happen that this thread does not get enough time to finish its computations just in time.

In such a scenario, the tread with lower priority would starve. It will remain away from the threads with higher priority

How can a synchronized block cause Thread starvation in Java?

It is not defined for synchronization that which thread will enter a synchronized block.

It may happen that if many threads are waiting for the entry to a synchronized block, some threads may have to wait longer than other threads.

Hence these threads with lower priority will not get enough time to finish their work in time

C Program to find factorial of a number using functions.

#include<stdio.h> #include<conio.h> void main() { int a,f; int fact(int); clrscr(); printf(“enter a no: ”); scanf(“%d”,&a); f=fact(a); printf(“factorial= %d”,f); getch(); } int fact(int x) { int fac=1,i; for(i=x;i>=1;i--) fac=fac*i; return(fac); }

Defination of the essential properties of operating systems

Define the essential properties of the following types of operating sys-tems: Batch Interactive Time sharing Real time Network Parallel Distributed Clustered Handheld ANSWERS: a. Batch processing:- Jobs with similar needs are batched together and run through the computer as a group by an operator or automatic job sequencer. Performance is increased by attempting to keep CPU and I/O devices busy at all times through buffering, off-line operation, spooling, and multi-programming. Batch is good for executing large jobs that need little interaction; it can be submitted and picked up later. b. Interactive System:- This system is composed of many short transactions where the results of the next transaction may be unpredictable. Response time needs to be short (seconds) since the user submits and waits for the result. c. Time sharing:- This systems uses CPU scheduling and multipro-gramming to provide econ...
