Final answer:
Large businesses use network management systems for operating system patching, reflecting an evolution from the early days of proprietary control by companies like IBM and Microsoft to more open solutions.
Step-by-step explanation:
Large businesses today typically rely on management systems within their networks to handle company-wide activities such as operating system patching. The history of computing tells us about the evolution from tightly controlled operating systems by manufacturers like IBM and software businesses such as Microsoft, to more open solutions that invite a broader approach to managing software resources. Operating system patching is critical because, as we know, a failing computer system can have significant impacts on customer service and company revenues. These management systems often have automated tools and features to efficiently roll out updates, secure devices, and manage resources across the organization.
