12. The Floppy Disk
In the early days of personal computing, floppy disks were the go-to way to save and transfer files. These square, flexible disks came in different sizes, with the 3.5-inch version being the most popular. Users inserted them into computers to store documents, photos, and software. Despite their limited storage capacity by today’s standards, floppy disks were revolutionary for their time. Over the years, USB drives and cloud storage replaced them entirely. Now, floppy disks have become nostalgic icons of early technology.
