External hard drives frequently include software to perform data backup automatically or at the press of a button. To use it as a standard hard drive it just needs a mass storage driver that all modern operating systems already include.
Portable hard drives are worth it if you need to take a lot of your data with you away from your computer. Some people use them as a safe back up for their computer system. If you have information that you want to be sure is backed up, then a portable hard drive may be worth it for you.
Like anything mechanical, hard drives will eventual wear out and need to be replaced.
Laptops have two types of memory, the hard drive (used to store your video, music, and photo files) and RAM (which affects how quickly your computer runs when multiple applications are running). The trend is for newer laptops to have larger hard drives. If you need extra space, portable hard drives are available for external storage.
Yes
i dont think you can Answer Flash drives are used as portable memory--like a floppy disk or a CD that you write to. You cannot use them to run a program. For that, you need the CPU.
true
No volts need a hard drive. However hard drives need a voltage. Usually about 5 for the data more for the physical movement of the drive.
it is a sub stance
Hard drives are one of the most important elements of computers. They even make external ones for those who need more room. They were first invented by IBM.
If you mean between hard drives and ssd's (solid state drives), then you need to read the wikipedia page on Solid State Drives, it has a comparison of the two technologies.
Yes!
The hard drives that are permanently located inside the system unit and not designed for removal are typically internal hard drives or solid-state drives (SSDs). These drives are installed directly onto the motherboard or into specialized drive bays and are used for the primary storage of the operating system, applications, and user data. Unlike external drives, internal drives are meant to remain in the system until they need maintenance or replacement due to failure.
