Answer 2

The advantages and disadvantages of the magnetic drum are as follows:

Advantages:

• Records of data can be kept for sequential or direct access.
• This disc had a high access and update speed and required no transaction sorting.
• To read or write data to some data files, they use the direct access mode.
• A tape system typically has a slower data transfer rate than a magnetic disc system.

Disadvantages:

• Pricey compared to magnetic tapes.
• To prevent them from collapsing, it must be stored in a space free of dust.
• This disc was more prone to security breaches and remote terminal access to private online disc files.
• Information security is challenging to maintain.
• For devices that need access that is sequential rather than direct or random, this is not ideal.
• The entire data stored on a disc drive or disc is lost in the event of a failure.
