Which development characterized the 1980s IT operations era?

• A. The rise of cloud computing
• B. Widespread Internet access
• C. Mainframes became obsolete
• D. The client-server model linked PCs with mainframes

Answer: (D)

Client-server computing, linking PCs with mainframes, is what defined the 1980s IT operations era. In this setup, personal computers act as clients that request services, while servers provide data processing, storage, and shared resources. This split distributes workloads across multiple machines, enabling local networks to support business applications with better scalability and manageability than a single centralized system. The result is a more decentralized, networked environment where users interact with applications running on servers from their PCs, laying the groundwork for widespread networked computing. Cloud computing didn’t exist in the 1980s and would come much later, with on-demand, scalable resources delivered over the internet. Widespread Internet access wasn’t yet the hallmark of IT operations in that era; while networks existed, public internet usage became mainstream in the 1990s. Mainframes did not become obsolete; they remained important and were complemented by servers, forming a hybrid environment rather than being phased out.
