Question

A way to overcome the problem of blocking threads is to use a technology referred to as __________, which converts a blocking system call into a nonblocking system call.

Answer 1

To overcome the issue of blocking threads, asynchronous I/O or non-blocking I/O technology transforms blocking system calls into nonblocking ones, enhancing system efficiency. A way to overcome the problem of blocking threads is to use a technology referred to as "asynchronous I/O" or "non-blocking I/O.

Step-by-step explanation:

A way to overcome the problem of blocking threads is to use a technology referred to as asynchronous I/O or non-blocking I/O, which converts a blocking system call into a nonblocking system call. In traditional blocking I/O, a thread is suspended by the OS and is not runnable until the data is available, which could lead to underutilization of system resources. Asynchronous I/O allows a system to handle other tasks while waiting for I/O operations to complete, thus improving efficiency. An example of this can be found with libraries like Node.js in JavaScript, which use non-blocking I/O to handle multiple connections concurrently.

This technology converts a blocking system call into a non-blocking one, allowing the program to continue executing other tasks while waiting for the I/O operation to complete.

Asynchronous I/O enables efficient multitasking by allowing a program to initiate an I/O operation and proceed with other tasks while waiting for the result. This approach enhances overall system responsiveness and performance.
