Question: 1 / 525

What are the four areas of system bottlenecks?

Processor, Memory, Disk, Network

A system bottleneck is a point of congestion in a computer system where delays and inefficiencies occur. These bottlenecks can occur in different areas of a system, but are typically found in the processor, memory, disk, and network. Option A correctly identifies these four areas as potential bottlenecks. Options B, C, and D have variations of the same components but are not as specific as option A. For example, option B uses the acronym "LAN" instead of "Network," and option C specifies "Hard Drive" and "Wifi" instead of "Disk" and "Network." Option D uses "Internet" instead of "Network," which is the most accurate term. Therefore, option A is the most comprehensive and accurate answer.
