stack overflow occurs when the on--chip stack capacity is exceeded. This can be detected by a comparison of the top-pointer, the last-pointer and the index specified for a create-frame operation ( for push). Initially the top-pointer is set to 1 and the last-pointer to 0, placing a dummy element on the stack.
If an index specified for a read access is greater than the number of valid on--chip stack elements, a stack underflow occurs

Why an operation to check queue overflow is not implemented on linked queue?
In linked queue we're dynamically allocating the memory and there's no fixed memory limit in Linked Queue. That's why there's no operation for overflow. I guess It's the correct reason
Algorithm to insert and delete an element from a circular queue?

What is the condition for the overflow in the linked lists?
In linked list if there is no any element inside it than we can say linked list is underflow.
What is the meaning of stack underflow?
Stack underflow occurs when an operation is attempted on an empty stack, resulting in an attempt to access a nonexistent element at the top of the stack. This can lead to errors or unexpected behavior in programs that rely on stack data structures. To prevent stack underflow, it is important to check the stack's current size before performing operations that could potentially lead to underflow.
What is meant by overflow in a digital circuit?
A overflow is a condition in which a calculation produces a unit of data too large to be stored in the location alloted to it. An overlow cannot happen when two numbers of opposite sign are added. An overflow may occur in an addition of binary numbers if the augend and addend are both positive or negative.
What are some common errors detected by the CPU?
Fixed point overflow, Floating point overflow, Floating point underflow, etc.
Algorithm to delete elements at both ends in a dequeue?
Delete Front---- DQDELETE_FRONT(QUEUE, FRONT, REAR, ITEM) 1. [check for queue underflow] If FRONT<0, Then: Print: "Queue is empty", and Return. 2. ITEM = QUEUE[FRONT]; 3. Set FRONT = FRONT + 1. 4. Return. Delete Rear---- DQDELETE_REAR(QUEUE, REAR, FRONT, ITEM) 1. [check for queue underflow] If REAR<0, Then: Print: "Queue is empty", and Return. 2. ITEM = QUEUE[REAR]. 3. Set REAR = REAR - 1. 4.Return.

What would result in an overflow?
An overflow occurs when you attempt a mathematical operation that results in a number that cannot be stored in the variable type you are using. C# projects only check for overflows if you have explicitly configured the project to do so (because it slighly slows down your application). To do this, you have to go into the Project Properties page, Build tab, click Advanced, and then choose "Check for arithmetic overflow/underflow" If you set this option, then this code, which attempts to add 1 to a integer that is already at the maximum value that the 32-bit integer type can hold, would cause an overflow: int a = int.MaxValue; a++;
What is the meaning of a stack overflow?
A stack overflow is a programming term used to identify when a function tries to access memory from a stack that does not exist. A stack, such as a queue or array, contains a limited number of memory spaces set aside when it is created. For example, if an array has 8 objects in it and a function tried to access an item at slot nine, which doesn't exist, it would cause a stack overflow.
What are types of Queue?
Queue is a data structure which is based on FIFO that is first in first out. Following are the types of queue: Linear queue Circular queue Priority queue Double ended queue ( or deque )
What is the plural of queue?
Queues is the plural of queue.
Which queue most efficient queue using array?
circular queue
