What else can I help you with?
A computer store sold a total of 300 items last monthThe store sold six times as many hard drives as they did CD-ROM drivesand half as many floppy drives as hard drivesBased on this informationhow?
240 hard drives, 20 floppy drives and 40 CD-ROM drives.
How does the computer process and store data efficiently?
Computers process and store data efficiently by using algorithms to quickly perform calculations and operations, organizing data into structured formats for easy access, and utilizing storage devices like hard drives and solid-state drives to store information in a way that can be quickly retrieved when needed.
What stores information on a computer?
Permanant information is stored in hard drives, usb drives, cds, dvds and the temporary information is stored in RAM (Random Access Memory).
The memory devices of computers such as hard disks and floppy disk drives use materials to store data?
magnetic
What are computer storage devices and how do they function within a computer system?
Computer storage devices are hardware components that store and retrieve data in a computer system. They function by saving data in a way that can be accessed quickly and efficiently by the computer's processor. This allows users to store files, programs, and other information for later use. Common types of storage devices include hard drives, solid-state drives, and USB flash drives.
What do hard drives do?
They store digital information in a relativly permenent form. Some hard drives called 'Hard Disc Drives' store data magnetically on a metal disc. Newer hard drives called 'Solid State Drives' store data electronically on flash memory.
What is the function of an hard drives?
To store information
What do hard drives floppy drives and Zip drives have in common?
They all store information.
What memory has an magnetic hard drive to improve system performance?
If you are referring to RAM, none because it would slow it down. Hard drives and floppies are magnetically written to.
What is a JAZZ drive?
A Jazz drive is similar to a Zip drive. Jazz drives are external storage devices that use cartridges to store information on. With portable hard drives and flash drives available, the Jazz drives are obsolete.

Can a magnet erase information from memory sticks and computers?
A magnet can only change information that is stored magnetically and if the magnet's magnetic field is strong enough. Memory sticks do not store information magnetically, they use Flash memory which stores information electrostatically. So no, a magnet can not erase information on a memory stick. Computers usually use hard disks which do store information magnetically, so in principle a magnet could erase information from a hard disk. However the magnet would have to be very strong (much stronger than is likely to be available at home) and held very close to the hard disk (probably be inside the computer case or even inside the hard disk case itself) to be able to to erase the information. Computers before the 1970s usually used magnetic core memory instead of DRAM as their main memory. While this stored information magnetically, the construction of the cores as rings made it impossible for any magnet to change the information: the 1 and 0 were opposite directions of magnetization around the ring shaped cores, while an external magnetic field is "linear" not "circular" and thus can't change the state of a core.
Magnetic hard drives contain round pieces of metal called which are coated with a magnetizable substance.?
Magnetic hard drives contain round pieces of metal called platters, which are coated with a magnetizable substance. This coating allows data to be stored magnetically on the surface of the platters. When the drive operates, read/write heads move across the platters to access or modify the stored information.
Will magnetic fields damage hard drives?
Computer disks (hard drives or older floppy drives) store their information by creating a magnetic charge on a tiny spot of the disk for each little bit of information, which can be read again later. Passing a strong magnetic field over the disk changes the saved charge and it can't be read again as organized information. CDs and DVDs don't store this way, so are safe from magnetic fields.
How is information stored magnetically to the computer hard drives?
The hard drive is split into many small regions, each containing a few hundred magnetic grains that are used to store one bit.The writing head of the hard drive contains an electromagnet or similar that can be used to turn magnetism on or off in the magnetic grains. The reading head can then read this information.The principle is pretty much the same as the one previously used for recordable tapes, whether music cassettes or VHS video tapes.See related links.
Does virtualization use virtual hard drives to store the virtual machines OS?
It can use either: real hard drives and virtual ones.
What is used to store information on a diskette?
There are several mass storage mediums that may be described as a disk (or disc), including floppy-disk, hard-disk and optical disc (CD-ROM, DVD, BluRay). Solid-state drives such as flash drives are not disks; there are no moving parts.
