Final answer:
Option C: Random access in magnetic tapes is slow compared to magnetic disks because tapes require sequential access, which is less efficient than the direct access provided by magnetic disks.
Step-by-step explanation:
Random access in magnetic tapes is c) slow, compared to magnetic disks. Magnetic tapes are a form of sequential storage, meaning they have to be wound and unwound to access specific pieces of data. On the other hand, magnetic disks, like hard drives, allow for direct access to stored information, making the retrieval process much faster. Magnetic tapes, therefore, are not well-suited for applications where data needs to be accessed rapidly or on a random basis. Instead, they are more commonly used for archival storage where access speed is not as critical.
Random access in magnetic tapes is very slow, compared to magnetic disks.
Magnetic tapes are sequential access storage media, which means that data can only be accessed in a fixed sequential order, starting from the beginning of the tape. On the other hand, magnetic disks provide random access, which allows data to be accessed in any order, regardless of its location on the disk.
For example, let's say you want to access a specific song on a magnetic tape. With random access on a magnetic disk, you can quickly jump to that song and start playing it. However, with sequential access on a magnetic tape, you would have to fast-forward through all the previous songs until you reach the desired one, making the process much slower.
