Saving data and instructions to make them readily available is the job of __________a.Storage Unitb.Output Unitc.Cache Unitd.Input Unit

Break Down the Problem

1. Identify the components mentioned in the question related to computer architecture.
2. Understand the functions associated with each unit.

Relevant Concepts

1. Storage Unit: This is used for storing data permanently.
2. Output Unit: This is responsible for providing results to the user.
3. Cache Unit: A small-sized type of volatile memory that provides high-speed data access to the processor.
4. Input Unit: This is used to input data into the computer system.

Analysis and Detail

• Storage Unit (a): While this stores data, it does not necessarily make it readily available in an immediate sense.
• Output Unit (b): This is not relevant since it outputs data rather than stores it.
• Cache Unit (c): This holds data temporarily to make it readily available for immediate access by the CPU.
• Input Unit (d): This gathers data but does not store it for later use.

Verify and Summarize

Among the options, the Cache Unit (c) is the most appropriate for the role of saving data and instructions to make them readily available, as it speeds up data retrieval for the processor.

Final Answer

c. Cache Unit
