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.
When you connect the drive to a computer, the computer presents the drive's file system to the user, allowing them open files, move file around, etc. Essentially, each file in the file system refers to a block of bytes, so the "flowers.
The file system in effect gives the user a name and probably an icon for a block of data bytes, and allows the user to perform operations on that data, like move it or copy it or open it with a program. The file system also tracks information about the bytes: how many there are, the time they were last modified. FAT32 is an old and primitive file system, but it is good where wide support is important. Persistent Storage Examples This one is easy to understand, since you have used files and files sytems e.
It broke, and so became a classroom example. Here is the flat "motherboard", a little smaller than a 8. At the center is the CPU. At the far right is the RAM memory. Just to the right of the CPU are a couple support chips. Prominently, one of the chips is covered with a copper "heatsink"..
What are the differences between hardware and software?
Here the mechanism is released so the CPU can be picked up. The fingernail sized CPU is packaged underneath this metal cover which helps conduct the heat from the CPU up to its heatsink. The gray stuff on the metal chip cover is "thermal paste", a material which helps conduct heat from the chip housing to its not shown heatsink.

Each pad is connected by a very fine wire to a spot on the silicon chip. Here is a picture of another chip, but with the top packaging removed. Your Own Computer Games with Python. Basic Computer Maintenance. An Introduction to Computer Security.
