function: the processor, or cpu (central processing unit), is responsible for executing instructions and performing calculations, essentially acting as the brain of the computer.storage: in contrast, storage refers to the components that retain data and files, including hard drives (hdd), solid-state drives (ssd), and other types of memory.speed: processors operate at high speeds, measured in gigahertz (ghz), enabling rapid execution of tasks and processing of data.capacity: storage is measured in gigabytes (gb) or terabytes (tb) and determines how much data can be saved and accessed over time.volatility: the processor operates in a volatile manner, meaning it loses its data when the power is turned off, while storage retains data even without power.data access: the cpu accesses data from storage to perform tasks, but it does so much faster than data can be retrieved from storage devices.types: processors come in various architectures (like x86 or arm) and core counts (single-core, dual-core, etc.), while storage can be mechanical (hdd) or flash-based (ssd).upgradability: upgrading a processor can significantly boost a computer's performance, while increasing storage capacity is often simpler and can be done with additional drives.cost: generally, high-performance processors tend to be more expensive than storage solutions with equivalent capacities.role in performance: while the processor determines how fast a computer can perform tasks, storage affects how much data can be saved and how quickly that data can be accessed, both contributing to overall system performance.
