DeadLock Detection Algorithm | Operating System | Mumbai University | Pyq may 2023

In this video, we dive into the deadlock detection algorithm using a real-world example with four processes and five resource types. Follow along as we apply the algorithm step-by-step to determine if the system is in deadlock and identify the deadlocked processes. This detailed explanation is perfect for semester 4 Information Technology students preparing for their exams. Let's make sure you understand every concept clearly and are well-prepared!
Detailed Explanation:

We have the following matrices and vectors representing our system:

1. Current Allocation Matrix (C):
Represents the number of each resource type currently allocated to each process.

```
RS1 RS2 RS3 RS4 RS5
P1: 0 1 1 1 2
P2: 0 1 0 1 0
P3: 0 0 0 0 1
P4: 2 1 0 0 0
`
2. Request Matrix (R):
Represents the additional resources each process may need to complete.

```
RS1 RS2 RS3 RS4 RS5
P1: 1 1 0 2 1
P2: 0 1 0 2 1
P3: 0 2 0 3 1
P4: 0 2 1 1 0
```

3. Available Vector (A):
Represents the number of each resource type currently available.

```
[0, 1, 0, 2, 1]
```

**4. Existing Resources Vector (E):
Represents the total number of each resource type in the system.

```
[2, 4, 1, 4, 4]
```
