Assignment Help:

Q. A Burroughs B7000/B6000 MCP file is able to be tagged as sensitive data. When such a file is removed its storage area is overwritten by some random bits. For what reason would such a scheme be useful?

Answer: This would be helpful as an extra security measure so that the old content of memory cannot be accessed either intentionally or else by accident by another program. This is particularly useful for any highly classified information.
