which among the following is a secondary storage device?
604173
Typical secondary storage devices include magnetic tape drives, magnetic disk drives, compact optical disk drives, and archival storage devices such as disk jukeboxes. Figure 1.6.

Auxiliary memory holds programs and data for future use, and, because it is nonvolatile (like ROM), it is used to store inactive programs… Secondary memory on a computer is storage for data and programs not in use at the moment.

A logical hard drive provides the operating system with additional storing space, eliminating the need of having to store files on multiple devices. When a physical drive is set up to a laptop or computer, it creates a unique C: disk. You can create additional drives by partitioning the physical disk.

There are no moving parts, and separate media is not necessary to read or record data. This type of storage media is called solid state memory, and differs from optical and magnetic drives.

A hard disk drive (HDD) is an old-school storage device that uses mechanical platters and a moving read/write head to access data. A solid-state drive (SSD) is a newer, faster type of device that stores data on instantly-accessible memory chips.

Difference between Primary and Secondary Memory While primary memory is the main memory of the computer which is used to store data or information temporarily, whereas secondary memory refers to external storage devices that are used to store data or information permanently.

A solid-state drive (SSD) is a new generation of storage device used in computers. SSDs replace traditional mechanical hard disks by using flash-based memory, which is significantly faster.

Computer memory is of two basic type – Primary memory(RAM and ROM) and Secondary memory(hard drive,CD,etc.). Random Access Memory (RAM) is primary-volatile memory and Read Only Memory (ROM) is primary-non-volatile memory.

A solid-state drive (SSD) is a new generation of storage device used in computers. SSDs replace traditional mechanical hard disks by using flash-based memory, which is significantly faster. Older hard-disk storage technologies run slower, which often makes your computer run slower than it should.
1323115
There are two types of external hard drive: hard disk drives (HDD, also known as mechanical or traditional hard drives) or solid state drives (SSD). An SSD is faster, lighter and less power-hungry, whereas an HDD drive will be cheaper and slower than an SSD.

The other storage category contains miscellaneous files that aren't included in the main categories (like photos and videos, apps, and email). Some of the most important other files include: ... Mail cache and mail attachments. Cache files associated with many apps. Cache and other system files generated by iOS.

External vs. External drives typically consist of a plastic case that houses a 3.5-inch desktop hard drive. These drives also require an external power supply. A portable drive, on the other hand, usually contains a 2-inch laptop hard drive and can be powered directly by the USB connector.

Memory or Storage Unit This unit can store instructions, data, and intermediate results. This unit supplies information to other units of the computer when needed. It is also known as internal storage unit or the main memory or the primary storage or Random Access Memory (RAM).
1282726
Hard Drives, CD-ROM and DVD-ROM drives, floppy disk drives, and tape drives are all examples of storage devices. ... It can read data from the storage medium but you can NOT change the data or save any new data on it.
1398116
RAM( random access memory) is not a secondary storage unit. ... RAM is a form of computer data storage that stores data and machine code currently being used.
34839
Primary storage refers to the main storage of the computer or main memory which is the random access memory or RAM. Secondary storage, on the other hand, refers to the external storage devices used to store data on a long-term basis.

An external hard drive is a device which is plugged into your machine to give almost-immediate storage space, without the need to open your computers internal storage and make upgrades. External drives are portable storage devices typically used to store data such as photos, videos, and documents.
