## What is race condition with example?

A simple example of a race condition is a light switch. In some homes, there are multiple light switches connected to a common ceiling light. When these types of circuits are used, the switch position becomes irrelevant. If the light is on, moving either switch from its current position turns the light off.

## What is race condition in programming?

A race condition occurs when two threads access a shared variable at the same time. The first thread reads the variable, and the second thread reads the same value from the variable.

What is race condition in Java with example?

In layman terms, a race condition can be defined as, a condition in which two or more threads compete together to get certain shared resources. For example, if thread A is reading data from the linked list and another thread B is trying to delete the same data.

### What is race condition Discuss How Do You Solve race condition problems with an example?

A race condition is a kind of bug, that happens only with certain temporal conditions. Example: Imagine you have two threads, A and B. If thread A is preempted just after having check that object. a is not null, B will do a = 0 , and when thread A will gain the processor, it will do a “divide by zero”.

### What is race condition in C?

What are race conditions? Race conditions in software or any system occur when the desired output requires that certain events occur in a specific order but that the events don’t always happen in that order. There is a ‘race’ between the events and if the wrong events win, the program fails.

What data have a race condition?

A race condition occurs when two or more threads can access shared data and they try to change it at the same time. Because the thread scheduling algorithm can swap between threads at any time, you don’t know the order in which the threads will attempt to access the shared data.

## What is race condition in flip flop?

Race condition occur in RS flip-flop. When the S and R inputs of an SR flip flop is at logical 1 and then the input is changed to any other condition, then the output becomes unpredictable and this is called the race around condition.

## How are race conditions tested?

The best way to test for race condition vulnerabilities is to have access to source code, in what is known as a “white box” assessment.

What is a race condition Mcq?

A Race condition refers to. A situation where several processes access and manipulate the same data concurrently. A situation where Single process access and manipulate the same data concurrently . A situation where No process access and manipulate the same data concurrently.

### How would you solve the race condition in a program?

To avoid race conditions, any operation on a shared resource – that is, on a resource that can be shared between threads – must be executed atomically. One way to achieve atomicity is by using critical sections — mutually exclusive parts of the program.

### How can race conditions be solved?

Race conditions can be avoided by proper thread synchronization in critical sections. Thread synchronization can be achieved using a synchronized block of Java code. Thread synchronization can also be achieved using other synchronization constructs like locks or atomic variables like java.

What is race condition in JK flip flop?

Race Around Condition In JK Flip-flop – For J-K flip-flop, if J=K=1, and if clk=1 for a long period of time, then Q output will toggle as long as CLK is high, which makes the output of the flip-flop unstable or uncertain. This problem is called race around condition in J-K flip-flop.

## What is race around condition in OS?

Race around is a situation where several process access and manipulate same data congruently and the outcome of execution depends on the particular order in which access takes place .

## How do you solve race around conditions?

There are three methods to eliminate race around condition as described below:

1. Increasing the delay of flip-flop. The propagation delay (delta t) should be made greater than the duration of the clock pulse (T).
2. Use of edge-triggered flip-flop.
3. Use of master-slave JK flip-flop.

What is race around condition problem?

Race around condition: For JK flip-flop if J, K, and Clock are equal to 1 the state of flip-flop keeps on toggling which leads to uncertainty in determining the output of the flip-flop. This problem is called Race around the condition.

### How do you debug a race condition?

Debugging Race Conditions

1. Run Code as Sequential Code. Not every bug is related to race conditions, so it’s possible that debugging in a sequential environment would be easier.
2. Use Log Statements.
3. Use IntelliJ Debugging Tools.

What is race condition C++?

## What is race condition and how it can be eliminated?

It can be eliminated by using no more than two levels of gating. An essential race condition occurs when an input has two transitions in less than the total feedback propagation time. Sometimes they are cured using inductive delay line elements to effectively increase the time duration of an input signal.

## What is a race condition in programming?

A race condition is a situation on concurrent programming where two concurrent threads or processes compete for a resource and the resulting final state depends on who gets the resource first. Race condition is not only related with software but also related with hardware too.

What is an example of a race condition?

Example of race condition 1 The previous value of the shared variable will be loaded into one of the registers of the CPU. 2 The value of money variable will be loaded into some another register. 3 The values of two variables will be stored in two registers and the result will be calculated. 4 Now, assign the result to the variable share.

### How to avoid a race condition in a shared resource?

The usual solution to avoid race condition is to serialize access to the shared resource. If one process gains access first, the resource is “locked” so that other processes have to wait for the resource to become available. Even if the operating system allows other processes to execute, they will get blocked on the resource.

### Are data races and race conditions compatible?

Many race conditions can be (and in fact are) caused by data races, but this is not necessary. As a matter of fact, data races and race conditions are neither the necessary, nor the sufficient condition for one another.
