CPU and Storage Devices Fundamentals

Which CPU component is primarily responsible for performing arithmetic and logic calculations?

• Cache memory speeding up data access

• Control Unit directing processor operations

• Arithmetic Logic Unit handling calculations

• Registers storing very fast temporary data

What is the main role of the Control Unit inside the CPU?

• Saves data permanently for firmware

• Performs addition, subtraction, and comparisons

• Directs and coordinates processor operations

• Stores instructions temporarily during execution

A program is running and needs fast, temporary working space. Which storage type does it use?

• ROM permanent firmware memory

• RAM volatile primary memory

• Optical disc removable media

• HDD mechanical long-term storage

You are tasked with speeding up a computer’s boot and app load times without increasing RAM. Which upgrade is the most effective?

• Add more USB flash drives

• Install additional optical disc drive

• Switch ROM to a larger capacity

• Replace HDD with an SSD drive

A developer uses fixed "if–then" logic to decide outputs. What type of system is being used?

• Data-driven learning system

• Hybrid stochastic system

• Rule-based decision system

• Unsupervised clustering tool

Which scenario best illustrates bias-in during machine learning?

• Training data misses several communities

• Predictions favor one group in outputs

• Model improves after added examples

• Algorithm runs slower on old hardware

You need faster access to repeatedly used data on a CPU. Which specification most helps this need?

• Higher cache size available

• More cores for multitasking

• Higher clock speed rating

• Newer instruction set design

Primary storage in a computer typically refers to

• RAM used for active data

• External USB flash drives

• Internal hard disk platters

• Cloud object storage buckets

Which is an example of secondary storage?

• Instruction register

• SSD drive

• RAM modules

• CPU cache lines

How does an SSD differ from an HDD?

• Uses spinning magnetic platters

• Relies on tape-based cartridges

• Stores data in optical layers

• Uses flash memory chips
