What do you mean by concurrent server?
concurrent server is a server which can handle multiple requests at a time.
What is a concurrent call?
A concurrent call refers to multiple calls or requests that are processed simultaneously, rather than sequentially. In telecommunications or computing, this means that the system can handle several interactions at the same time, improving efficiency and response times. For example, in a call center, multiple agents can speak with different customers at once, or in software applications, multiple users can access resources concurrently without waiting for others to finish. This capability is crucial for scalability and performance in various systems.
What is the special code that prioritizes service requests from the operating system?
A special numerical code that prioritizes device requests from the operating system is called
Can both client and servers use the same protocol port on the same computer at the same time?
Yes - this is frequently the case with web servers, which service requests on port 80 from multiple locations simultaneously.
How does a networked server manage requests from multiple clients for different services?
The applications installed help the networked server manage requests from multiple clients for different services. The server receives the requests and delegates them.
What is difference between single threaded servlet and multi threaded servlet?
The single thread model means that your servlet would not be multi-threaded. If there are two concurrent requests to your servlet then 2 instances of your servlet will be created to process these 2 requests. You can implement the single thread model by implementing the SingleThreadModel interface in your class. This is just a marker interface and does not have any methods. The multi threaded model means that your servlet would be multi-threaded and only one instance would exist. Multiple concurrent requests would be served by the same instance but in different threads. You can implement the multi threaded model by not implementing the SingleThreadModel interface in your servlet class.
What does the server and the client use to keep each download separate?
The server and the client use unique identifiers, such as session IDs or download tokens, to keep each download separate. These identifiers help track individual download requests and their associated data. Additionally, the server may implement techniques such as file segmentation and management of concurrent connections to ensure that each download is processed independently without interference. This organization allows for efficient handling of multiple downloads simultaneously.
What happens if multiple connection requests arrive at about the same time at the server?
Servers are deigned to handle multiple connection requests. Depending on the service, for each request a socket or thread is opened.
A special numerical code that prioritizes device requests from the operating systems is called?
A special numerical code that prioritizes device requests from operating systems is called a "priority value" or "priority level." This code helps the operating system manage access to resources by determining the order in which requests are processed, ensuring that higher-priority tasks are addressed before lower-priority ones. This mechanism is crucial for maintaining efficient system performance and responsiveness.
What is an interrupt operating system and how does it handle interruptions in the execution of tasks?
An interrupt operating system is a type of operating system that can pause the execution of tasks to handle unexpected events or requests. When an interruption occurs, the operating system temporarily stops the current task, saves its state, and then processes the interrupt. Once the interrupt is handled, the operating system resumes the original task from where it left off. This allows the system to efficiently manage multiple tasks and respond to external events in a timely manner.
What operating system is designed to deal with input output and processing requests from many users?
Unix was designed specifically to handle many users and requests at the same time (time-sharing).
What is thread safe servlet?
A thread-safe servlet is a type of servlet that can handle multiple requests simultaneously without leading to data inconsistency or corruption. This is achieved by ensuring that shared resources are properly synchronized, often by using mechanisms such as synchronized methods or blocks. In a thread-safe servlet, care must be taken to avoid issues like race conditions, ensuring that the servlet remains reliable and stable under concurrent access. Generally, it's advisable to keep servlets stateless or use instance variables cautiously to maintain thread safety.
