Floppy disk: Floppy disk is the first widely available removable and removable storage device. This is why most of the "Save" icons look like that, they are emulated on a floppy disk. They function like hard drives, albeit on a much smaller scale. The storage capacity of floppy disks never exceeded 200MB before CDRW and flash drives became the preferred storage media. The iMac was the first personal computer released without a floppy drive in 1998. Since then, the more than 30-year reign of the floppy disk has quickly died down.
Random Access Memory (RAM): Random Access Memory, or RAM, is the main memory in a computer. When you are working on a file on your computer, it temporarily stores the data in your RAM. RAM allows you to perform everyday tasks like opening apps, loading web pages, editing documents, or playing games. It also allows you to switch from one task to another without losing your progress. Basically, the more RAM in your computer, the smoother and faster you can do more tasks.
Hard Drive (HDD): The hard drive (HDD) is the original hard drive. These are magnetic storage devices that have been around since the 1950s, although they have evolved over time. Hard drives are made up of a stack of rotating metal disks called platters. Each spinning disk contains billions of tiny pieces that can be magnetized to represent bits (1 and 0 in binary code). An actuator arm with a read/write head scans the turntables and magnetizes the pieces to write digital information to the hard drive, or detect magnetic charges to read information from.
Solid State Drives (SSDs): SSDs appeared much more recently, in the 90s. SSDs don't rely on magnets and drives, but instead use a type of flash memory called NAND. In an SSD, the semiconductor stores information by varying the currents of the circuits contained in the drive. This means that unlike hard drives, SSDs do not require moving parts to function. For this reason, SSDs are not only faster and easier to operate than hard drives (hard drives take longer to gather information due to the mechanical nature of the disks and their heads), but in general they outlasts hard drives (with so many complex moving parts, hard drives are prone to damage and wear and tear).
