Partition: A partition is a section of a physical drive that functions like a separate storage space. One drive can be divided into multiple partitions. External Drive: This refers to any storage device connected from outside the computer—USB drives, external HDDs, SSDs, SD cards, etc. Why Create a Partition? To organize data (e.g., one partition for backups, another for media). To use different file systems on the same drive (e.g., NTFS + exFAT). To separate personal and work files. For better management or dual-use across devices.
