magnetic tape
A magnetic tape is a secondary storage media used to access data in a sequential way
Summary of secondary storage media. Floppy disk, direct access and removeable.Use Slow Sequential Access Hard disk, high capacity and fastest direct access. Use Store Programs and Data CD-ROM High capacity and removable direct access. Use Entertainment Software, Reference Material Magnetic Tape, High capacity and inexpensive.Use Back-up Programs and Data.

The terms direct access and random access describe the same concept. They mean that an element of data or instructions (such as a byte or word) can be directly stored and retrieved by selecting and using any of the locations on the storage media. They also mean that each storage position (1) has a unique address and (2) can be individually accessed in about the same length of time without having to search through other storage positions. For example, each memory cell on a microelectronic semiconductor RAM chip can be individually sensed or changed in the same length of time. Also, any data record stored on a magnetic or optical disk can be accessed directly in about the same period Sequential access storage media such as magnetic tape do not have unique storage addresses that can be directly addressed. Instead, data must be stored and retrieved using a sequential or serial process. Data are recorded one after another in a predetermined sequence (e.g., numeric order) on a storage medium. Locating an individual item of data requires searching the recorded data on the tape until the desired item is located.

No. ROM and RAM are primary storage. Examples of secondary storage would be floppy disk, hard disk, flash drive, etc. haahahaha
Hard drive, external hard drive, floppy disk, memory stick, CD-ROM and Recordable DVD are all storage devices.
There are many types of storage media, two of them are USBs, or thumb drives, and external hard drives.
Typically random access memory (RAM) is the primary storage device and the slower rotating magnetic media (disc drive) is the secondary storage device. Other devices like USB thumb drives and other removable media are considered tertiary (3rd level) storage devices
possibly firewire. its 400mb/sec
Oh, dude, storage media is where you keep your stuff, like a hard drive or a USB stick. Data media is what's actually on those things, like the files and pictures you store. So, it's like the difference between the shelf you put your books on and the actual books themselves.
