c) A type of wireless router
d) A tool for managing bandwidth
Answer:
a) A server that acts as an intermediary between a user and the internet
Explanation:
A proxy server is a server that acts as an intermediary between a user’s device and the internet. When a user sends a request to access a website, the request first goes to the proxy server, which forwards it to the website and then returns the response to the user.
Proxy servers are used to enhance privacy, improve security, and control access to certain websites or online services. They can also cache web pages to improve loading times for frequently visited websites.
By using a proxy server, users can mask their IP address and access content that may be restricted in their region, adding an extra layer of anonymity to their browsing activities.
