Critical components in computing refer to hardware or software elements essential for the proper functioning and performance of a system. These components play a pivotal role in ensuring the reliability, availability, and security of computer systems and networks. Examples of critical components include processors, memory modules, storage devices, network interfaces, and power supplies at the hardware level, as well as operating systems, databases, security software, and middleware at the software level. Failures or malfunctions in critical components can lead to system downtime, data loss, security breaches, or degraded performance, resulting in significant disruptions to business operations and user productivity. To mitigate risks associated with critical component failures, redundancy, fault tolerance, and robust monitoring and maintenance practices are often employed to ensure system resilience and continuity of operations.
