comprehension of class 11​

Answer 1

Answer:

B.

a) The classic definition of spam is unsolicited bulk messages, that is, messages sent to multiple recipients who did not ask for them. The problems caused by spam are due to the combination of the unsolicited and bulk aspects; the quantity of unwanted messages swamps messaging systems and drowns out the messages that recipients do want for practical and legal reason, different organizations have different definitions of spam. When a recipient gets a single message, it can be difficult to tell whether that message was part of a group sent in bulk, so a common alternative definition is unsolicited commercial e-mail, on the theory that most unwanted mail is commercial. Many mailbox providers consider it to be mail their users don’t want, or mail their users complain about, since their goal is to minimize the support costs associated with complaints. In practice these varying definitions describe approximately the same set of messages.
