INTRODUCTION:
"Trace-based collection" in the context of software engineering generally
refers to a method of garbage collection used in programming languages like Java
and C#.
It allows programmers to define and use efficient data structures on the fly,
instead of being restricted to predefined types like arrays or linked lists.
Definition:
Trace-based garbage collection is a technique used to manage memory in
programming languages where the system automatically deallocates memory that is
no longer in use, thus preventing memory leaks and improving program efficiency.

Real-World Applications:
1) Examines practical applications of trace-based garbage collection in programming
languages and large-scale systems.
2) Illustrates its usage scenarios and impact on real-world performance.
Advantages:
1) Automatic Memory Management: Developers don't need to manually allocate and
deallocate memory, reducing the risk of memory leaks and dangling pointers.
2) Efficiency: By reclaiming memory automatically, trace-based collection helps in
improving overall program performance and resource utilization.

Disadvantages:
Overhead: The tracing process incurs runtime overhead as it involves scanning
through all reachable objects in memory.
Pause Times: In some cases, the garbage collector may need to pause the execution
of the program while it performs garbage collection, leading to potential latency
issues in real-time systems.
Tuning: Configuring the garbage collector parameters to optimize performance can
be non-trivial and may require experimentation.

CONCLUSION:
Trace-based garbage collection is a powerful memory management technique used in
modern programming languages, offering automatic memory cleanup and improved
program efficiency. However, understanding its workings and fine-tuning its parameters
are essential for achieving optimal performance in applications.
