Answer: Middleware is a program that acts as the middle connection for a client and server .It helps the client and server to connect with each other for sending the request,  communication, etc. Middleware is designed in such a way that the functioning does not gets noticed by the client and server.

Example- Two-tier architecture of the client and server for database application can be the train ticket reservation. The reservation made by a people will be according to the time , the person who gets chance to access the reservation first will get the ticket while others wait in queue.

If any query regarding the reservation according to the database occurs then Java Database connectivity (JDBC) will act as the middleware for the Java data collection between the application(client section) and database (server).

Hunter-Best [27]

Answer:

A computerized light dimmer is one helpful development in lighting equipment. Computerized light dimmers help to control the brightness of light. These dimmers lower or increase the intensity of light. I first noticed light dimmers in a scene from the movie Children of Men. In a war scene, innocent people are shown running helter-skelter to save their lives. Artificial lights are used in scene to create that dark appearance in broad daylight, which makes the scene look gloomy and scary. It helped to generate the feeling of uncertainty and suspense through the proper use of lights. Light dimmers help light designers to create the exact atmosphere that the director demands for a scene. Also, because of dimmers, a light designer need not use extra accessories to diffuse light or make the scene brighter.

Privacy a. is an absolute value so corporate interests cannot be considered when it comes to employee privacy. b. is guaranteed
zmey [24]

Answer:

C. Must be respected if we are to function as complete, self-governing agents.

Explanation:

<em>Privacy</em> is the boundaries that are set up to protect us against unwanted intrusion or interference, and it forms the basis of our interaction with the world.

<em>Privacy laws</em> are set-up to protect individuals from unwanted and unapproved access to privacy by individuals, organizations, and government. This is greatly adhered to in many countries.

To some extent, privacy is considered to overlap with security, because, when private information such as social security number, bank card details, account names, and details, etc. are accessed inappropriately, the individual's security is greatly compromised.

Therefore, privacy must be greatly respected if we are to function as complete, self-governing agents.
