The answer is proxy server
A proxy server acts as an immediate or a gateway between you, the proxy client (example, the browser) and the internet or the destination website that you want to visit. Proxy servers are designed to re-route traffic and obscure source and destination. For instance, if you want to request a page like brainly, a proxy server will be able to retrieve this page for you by providing only its IP address to the site and act as a mediator between clients and the requested server. This however, does not mean that there is no link between you and this website. It means that all the information along with the requests you made will be collected by the proxy server.
Answer:
B. Virtual reality
Explanation:
In a virtual reality context, the visual and auditory senses of the user are fed by data (images, sounds) from the computer using a goggle and earphones. That allows the person to be totally cut off her real physical environment and be totally immersed into the world (reality) managed by the computer.
Not to be confused with<u> augmented reality</u>, where the physical reality and perception of it aren't changed... but an additional layer of information is added on top of it. Like pointing your phone camera to a building and getting information about the building displayed on your phone.
