How do resource limitations impact system performance?

Resource limitations can significantly degrade system performance, causing slow response times, system crashes, and reduced functionality.

In more detail, every computer system has a finite amount of resources, such as processing power (CPU), memory (RAM), storage space (hard drive or SSD), and network bandwidth. These resources are shared among all the applications and processes running on the system. When the demand for these resources exceeds their availability, the system's performance can be negatively impacted.

For instance, if a system is running multiple resource-intensive applications simultaneously, it may exhaust its CPU capacity. This can result in slower processing times as tasks queue up waiting for the CPU to become available. Similarly, if the system's memory is fully utilised, it may have to resort to using slower disk-based virtual memory, which can significantly slow down the system's response times.

Storage space is another critical resource. If a system's storage space is nearing capacity, it can hinder the system's ability to read and write data efficiently. This can cause applications to run slower and may even lead to system crashes if the system runs out of space to perform essential operations.

Network bandwidth is also a crucial resource, especially for systems that rely on internet connectivity. If a system's network bandwidth is limited, it can slow down the speed at which data can be sent and received. This can result in slower internet browsing, lag in online gaming, buffering in video streaming, and delays in downloading or uploading files.

Furthermore, resource limitations can also reduce a system's functionality. For example, if a system lacks the necessary resources to run a particular application, it may not be able to run the application at all. Or, if a system is constantly running at its resource limits, it may not have the capacity to handle unexpected spikes in demand, which could lead to system crashes or other failures.

In conclusion, resource limitations can have a significant impact on system performance. They can cause slow response times, system crashes, and reduced functionality. Therefore, it's essential to manage system resources effectively to ensure optimal performance.
