Examples of control measures in the computer are warnings or prompts that pop up whenever an operation is detected to overlap with another operation and the System Task Manager to monitor the activities and determine the speed and efficiency of processing within the computer.

4. Ergonomics is the science wherein technical fields such as engineering and industrial design are used to develop ideas, devices, and solutions that are suitable to the working conditions of the user. In the field of information technology and computer-mediated jobs, ergonomics is critical because it ensures that the users achieve a certain level of comfort physically that would make computing or computer-related work more manageable and ultimately, more efficient.

In contrast, SRAM is static; therefore its memory does not need refreshing and memory in it remains even when there's no power. EPROM is an erasable programmable read-only memory, chips wherein memory can be erased either electronically or thru ultraviolet light. PROM, meanwhile, is a memory chip not erasable electronically or thru UV light. Because SRAM is a more reliable and versatile memory chip than DRAM, the former is more preferred to be upgraded during a computer and/or systems upgrade. Upgrades could start from 128MB, but could increase to 256MB and 512MB depending on the user's requirements and budget.

7. The pie chart is best used in showing data in proportions (i.e., part of a whole) and if the categories are less than 10.
