A distributed operating system distributes tasks across multiple servers, providing better performance and availability. Examples include UNIX, Linux, and Windows. Grid computing is an example of distributed computing. Algorithms are used to manage tasks, with more advanced algorithms providing better performance.
A computer operating system (OS) is one of the most important aspects of a computer. It is responsible for managing the underlying tasks and orchestrating computer programs. A distributed operating system is a system that distributes the load across multiple computer hardware servers. This type of operating system offers better performance and availability because it is distributed across multiple components.
Most operating systems come in distributed versions. Some examples include UNIX®, Linux® and the Windows® operating system. When the operating system is distributed, it must be installed on multiple servers, which requires special configuration and management processes. This typically requires system engineers to manage the project.
A distributed operating system is configured as a cluster of servers that share memory and tasks. These servers act in unison and provide more power than a single large computer server. This typically results in better performance because the load is distributed across multiple servers.
Grid computing is a good example of distributed computing. This system uses Internet-connected computers to complete complex tasks that require high processing power. Using a distributed model takes advantage of the capacity of the idle computer because it shares multiple servers.
Computer capacity is known as the maximum available processing power of a computer system. It is usually calculated based on the available memory and processing units of the hardware platform computer. A distributed system provides additional capacity because it includes multiple servers.
There are specific algorithms used for a distributed operating system to handle task management. This arrangement is designed to process single tasks across multiple servers based on priority and expected processing time. These algorithms vary in complexity, but are designed to make the most of the processing power available from shared servers.
A round-robin algorithm is an example of a simple algorithm used in a distributed operating system. This technique distributes incoming computer activity to multiple servers based on a simple counting algorithm. Each task is assigned a specific number that corresponds to a specific server within the chain of available servers.
Some distributed operating system models monitor the available capacity of each server in the chain. This typically provides better performance than simple round-robin techniques because server load is based on actual available processing power. Advanced algorithms are more common in sophisticated multiprocessing operating systems.
