Variable (or Dynamic) Partitioning in Operating System

In operating systems, Memory Management is the function responsible for allocating and managing a computer’s main memory. The memory Management function keeps track of the status of each memory location, either allocated or free to ensure effective and efficient use of Primary Memory.

Below are Memory Management Techniques.

In the Contiguous Technique, the executing process must be loaded entirely in the main memory. The contiguous Technique can be divided into:

What is Variable (Dynamic) Partitioning?

It is a part of the Contiguous allocation technique. It is used to alleviate the problem faced by Fixed Partitioning. In contrast with fixed partitioning, partitions are not made before the execution or during system configuration. Various features associated with variable Partitioning-

Dynamic Partitioning

Advantages of Variable(Dynamic) Partitioning

Disadvantages of Variable(Dynamic) Partitioning

No Internal Fragmentation

Now P5 of size 3 MB cannot be accommodated despite the required available space because in contiguous no spanning is allowed.

Key Points On Variable (Dynamic) Partitioning in Operating Systems

FAQs on Dynamic (Variable) Partitioning

Q.1: What is the basic difference between Fixed Partitioning and Variable Partitioning?

Answer:

Fixed Partitioning helps in creating memory of identical sizes whereas dynamic partitioning helps in creating memory of variable sizes.

Q.2: Which algorithms work best for Dynamic Partitioning?

Answer:

The Worst Fit Algorithm works best for Dynamic Partitioning.

Q.3: What is Data Partitioning?

Answer:

The process of dividing up data among several tables, drives, or locations in order to enhance database manageability or query processing speed is known as data partitioning.
