# Linear Queue Vs Circular Queue: What’s the Difference?

In this article, we’ll be discussing the difference between a linear queue and a circular queue. We’ll also be giving you an overview of their respective advantages and disadvantages. After reading this article, you should have a better understanding of how these queues work and which one is best for your needs.

## What is a Linear Queue?

A linear queue is a type of queue in which items are added to the front of the queue in sequence. The first item added to the queue becomes the first item in the queue and subsequent items are added to the end of the queue. A linear queue is often used for tasks that can be completed in a fixed amount of time, such as waiting in line at a store.

A circular queue is a type of queue in which items are added to the back of the queue in random order. The first item added to the queue becomes the first item in the queue and subsequent items are added to anywhere within the available space in the circular queue. A circular queue is often used for tasks that can be completed in an undefined amount of time, such as waiting for a bus or file download.

## What is a Circular Queue?

A circular queue is a type of queuing system in which each item remains in the queue until it is either served or removed by the system. This contrasts with a linear queue, which is a type of queuing system in which items are served in an order determined by the time of arrival. A circular queue can be more efficient because it allows the system to serve items in batches, which can save time.

## How do they work?

Linear queues are usually implemented using a First In, First Out (FIFO) algorithm. This means the first item queued in the queue is the first to be processed. The next item is then added to the end of the queue, and so on. Circular queues use a different algorithm called Last In, First Out (LIFO). This means that the last item queued in the queue is the first to be processed.

Linear queues are often preferred over circular queues because of their advantages. Linear queues allow for more efficient processing of tasks, since the items queued up in the queue are processed in order. Additionally, this type of queue is less susceptible to overload, since the number of items queued up does not increase exponentially as the number of tasks processed by the queue decreases.

However, linear queues have several disadvantages. First, they can be relatively inefficient when it comes to processing large numbers of items. Second, if a task in the queue becomes blocked, it can take a long time for the item to be processed. Finally, if the queue is full, it can be difficult to add new items to it.

When it comes to managing work queues, there are two main types of queues: linear and circular.

Linear queues are simple, consisting of a single queue of tasks that workers can access in any order. Workers can move from task to task, but once they finish working on a task, they can’t start working on another. This makes linear queues ideal for tasks where a worker can complete one task and then move on to the next without waiting for someone else.

Circular queues are more complicated, consisting of multiple queues with different rules for when tasks can be processed. For example, in a ring queue, each worker gets assigned a specific lane, and once they finish their lane, they can start working on the next lane. This way, tasks don’t have to wait for someone else and workers can work on multiple tasks at the same time.

There are several advantages and disadvantages of using each type of queue. Here are some key points to consider:
