Hard drives are an essential component in modern computing systems, serving as the primary storage medium for digital data. As part of the electronics and computer categories, hard drives utilize complex controller area network (CAN) technology to manage data flow and input devices, such as keyboards or mice, interface with them to facilitate user interaction. Hard drive architecture consists of one or more circular disks coated with a magnetic material that store information in sectors. Read/write heads mounted on mechanical arms access the stored data by moving across the disk surface. The capacity of hard drives has grown exponentially over time, allowing for the storage of vast amounts of digital content, from documents and images to multimedia files and software applications. Despite the emergence of solid-state drives (SSDs) as a high-performance alternative, hard drives remain popular due to their lower cost per gigabyte and widespread compatibility with various computing platforms.
