,Deadlock and Memory
Management

, Introduction
 The Operating System's fundamental role is as
a resource manager.
 Both Deadlock and Memory Management are critical
instances of this responsibility, dealing with the
allocation and management of finite system resources—
be it I/O devices, CPU cycles, or physical memory.
 They address a central conflict in modern
computing: the tension between concurrent execution
and system stability/efficiency.

, Introduction
 This lecture focuses on these two of the most
critical and complex challenges an operating
system (OS) must handle: Deadlocks and Memory
Management.
 The OS serves as a resource manager, and its
primary job is to ensure fair, efficient, and correct
resource allocation while simultaneously providing
an abstraction of the underlying hardware (like
memory) to applications.
Deadlock deals with the efficient and correct allocation

of resources (like CPUs, files, printers, memory, etc.) in a
concurrent environment. If not handled, it can lead to
system stagnation, where processes indefinitely wait for
resources.
