Linear Queue<\/h3>\n

\"\"<\/a><\/p>\n

A linear queue, as described in the introduction, follows the FIFO (First-In-First-Out) principle. Elements are added at the rear and removed from the front. It has a fixed size and may become full, causing enqueue operations to fail.<\/p>\n

Applications<\/h3>\n

Linear queues are typically used for:<\/p>\n

    \n
  • Task Scheduling: Managing processes and tasks in operating systems.<\/li>\n
  • Print Job Management: Handling print jobs in printers.<\/li>\n
  • Breadth-First Search (BFS): Graph traversal in algorithms.<\/li>\n
  • Data Buffering: Ensuring orderly data transfer in networking.<\/li>\n
  • Print Spooling: Managing print requests in systems.<\/li>\n
  • Call Center Systems: Handling incoming customer calls.<\/li>\n
  • Customer Service Chatbots: Processing customer inquiries.<\/li>\n
  • Data Processing Pipelines: Sequential data processing.<\/li>\n
  • Order Processing: Fulfilling customer orders in retail.<\/li>\n<\/ul>\n

    Queue Operations<\/h3>\n

    Enqueue<\/strong>
    \nAdding an element to the back (also known as the rear or tail) of the queue.<\/p>\n

    Dequeue<\/strong>
    \nRemoving and returning the element from the front (also known as the head) of the queue.<\/p>\n

    Peek<\/strong>
    \nViewing the element at the front of the queue without removing it.<\/p>\n
