Answer:

Automatic and Explicit Buffering.

In the case of explicit buffering, the length of the queue is provided while in automatic buffering the queue size needs to be indefinite. In automatic buffering there is no need to block the sender while coping the message. While in explicit buffering the sender is blocked for the space in queue.

No memory is being wasted in explicit buffering.

Send by Copy and Send by Reference.

Explain the differences between copyright, fair use, and trademark?
ValentinkaMS [17]

A trademark is an easily recognizable symbol, phrase, or word that denotes a specific product. It legally differentiates a product or service from all others of its kind and recognizes the source company's ownership of the brand.

"Copyright" literally means the right to copy but has come to mean that body of exclusive rights granted by law to copyright owners for protection of their work. Copyright protection does not extend to any idea, procedure, process, system, title, principle, or discovery.

Fair use is a doctrine in United States law that permits limited use of copyrighted material without having to first acquire permission from the copyright holder.
