Scatter-Gather I/O is a technique used in computing to efficiently handle data input and output operations by allowing data to be read from or written to multiple buffers in a single operation. This method reduces CPU overhead and enhances performance by minimizing the number of system calls needed for data transfer, making it particularly useful in high-performance network and file systems.

CPU overhead refers to the extra processing time and resources required by the CPU to manage tasks beyond the primary computation, such as context switching, memory management, and handling interrupts. Minimizing CPU overhead is crucial for optimizing system performance and ensuring efficient resource utilization in both hardware and software applications.

Performance enhancement involves strategies and interventions designed to improve individual or team efficiency and effectiveness in various activities, often focusing on physical, cognitive, or organizational aspects. It encompasses a wide range of techniques from physical training and nutrition to cognitive behavioral strategies and technological aids, aiming to maximize potential and achieve superior outcomes.

Performance Enhancement

System calls provide an essential interface between a process and the operating system, allowing user-level applications to request services such as file manipulation, process control, and communication. They are crucial for resource management and ensuring security and abstraction in modern computing environments.
