Partition table

A partition table is a map stored on a computer's storage device, like a hard drive or SSD, that organizes how the space is divided into sections called partitions. Each partition acts like a separate "room" within the drive, allowing the system and user to manage data more efficiently, install multiple operating systems, or run different applications independently. Think of it as an index that tells the computer where each segment begins and ends, ensuring data is stored correctly and accessible. The partition table is crucial for system startup and proper functioning of storage devices.
