Topic 3: Computer Peripherals – Storage Show 1. Secondary storage is the physical material on which a computer keeps data, instructions, and information. 2. Which of the following is not a secondary storage medium? B. RAM 3. A(n) storage device is the computer hardware that records and/or retrieves items to and from storage media. 4. Optical disks use magnetic particles to store data, instructions, and information on a disk’s surface. 5. Which is a magnetic storage medium? B. Hard disk 6. A(n) platter disk is a storage device that contains one or more inflexible, circular platters that store data, instructions, and information. 7. Experts estimate that hard disks using perpendicular recording will provide storage capacities about 10 times greater than disks using longitudinal recording. 8. Which of the following is not a characteristic of a hard disk like the one shown in the accompanying figure? D. chip 9. Hard disks, like the one shown in the accompanying figure, spin at 5,400 to 15000 rpm. 10. A head crash occurs when the read/write head of a hard disk, like the one in the accompanying figure, touches the surface of a platter. 11. A backup is a duplicate of a file, program, or disk that can be used in case the original is lost, damaged, or destroyed. 12. A group of two or more integrated hard disks is called a RAID. 13. A USB hard drive enables mobile users easily to transport photos and other files from one computer to another. 14. A disk controller consists of a special-purpose chip and electronic circuits that control the transfer of data, instructions, and information from a disk to and from the system bus and other components in a computer. 15. Which is not a type of disk controller? D. UMD Identify the letter of the choice that best matches the phrase or definition. 1. Kind of CD that stores photos in the jpg file format - Archive 2. Storage media that consists of a flat, round, portable disc made of metal, plastic, and lacquer - Optical disc 3. Technology that works with specially coated optical discs to etch labels directly on the disc- LightScribe 4. Type of media that consists entirely of electronic components - solid state 5. Interface that is much faster than USB and FireWire - eSATA 6. A server connected to a network with the sole purpose of providing storage - NAS 7. A newer type of SCSI that uses serial signals - SAS 8. An ideal storage solution for users who must have the data available when they attempt to access it - RAID 9. Kind of storage that is an Internet service - cloud 10. A storage device that typically uses flash memory to store data, instructions, and information- SSD
What is the device used to store data and information?A hard disk drive or solid state drive holds all of the data; files, photos, programs, music, and movies, that the user wants to keep. Removable, external media storage devices such as flash drives and read/writeable CDs and DVDs are also secondary storage.
Which device is used for storing data and instructions?Storage devices can include hard disk drives (HDDs), flash-based solid-state drives (SSDs), optical disc drives, tape systems and other media types.
What type of memory is flash memory?Flash memory, also known as flash storage, is a type of nonvolatile memory that erases data in units called blocks and rewrites data at the byte level. Flash memory is widely used for storage and data transfer in consumer devices, enterprise systems and industrial applications.
Is flash memory a storage device?Flash memory is widely used to store data and code used in embedded systems. It is a non-volatile storage medium, meaning that it can retain data without a power supply.
