You understand that what you were working on is gone.

RAM has been wiped clean, leaving you only with what you last saved to disk below. Hard drive - stores bytes as a magnetic pattern on a spinning disk - aka "hard disk" - High pitch spinning sound you may have heard Hard drives have been the main, persistent storage tech for a long time BUT now flash is getting more popular.

Persistent Storage, Newer Technology: Flash "Flash" is a transistor-like persistent storage technology "solid state" - no moving parts -aka "Flash drive" -aka "Flash memory" -aka "SSD": Solid State Disk Flash is better than a hard drive in every way but cost - faster, more reliable, less power Flash is more expensive per byte Formats: usb key, SD card in camera, flash storage built into a phone or tablet or computer Flash used to be very expensive, so most computers used hard disks Flash is getting cheaper Moore's law However per-byte, hard drives are still substantially cheaper Not to be confused with "Adobe Flash", a proprietary media format Warning: flash does not persist forever.

It may not hold the bits past 10 or 20 years.

What are the differences between hardware and software?

Nobody knows for sure Persistent storage - long term storage for bytes as files and folders. Persistent means that the bytes are stored, even when power is removed.

A laptop might use a spinning hard drive also known as "hard disk" for persistent storage of files. The hard drive reads and writes magnetic patterns on a spinning metal disk to store the bytes, while flash is "solid state": no moving parts, just silicon chips with tiny groups of electrons to store the bytes.

In either case, the storage is persistent, in that it maintains its state even when the power is off. A flash drive is faster and uses less power than a hard disk.

However, per byte, flash is significantly more expensive than hard drive storage. Flash has been getting cheaper, so it may take over niches at the expense of hard drives.

Note that Adobe Flash is an unrelated concept; it is a proprietary media format. Flash storage is what underlies USB thumb drives, SD cards for use in cameras, or the built-in storage in a tablet or phone. File System How are the bytes in persistent storage organized? Bytes on a flash drive?

Typically the hard disk or flash disk is formatted with a "file system" which organizes the bytes into the familiar pattern of files and directories, where each file and directory has a somewhat useful name like "resume.
