Answer:
d. All of these.
Explanation:
A VPN is an acronym for Virtual Private Network and it's a secured, encrypted and private web-based service used for accessing region-restricted and censored internet content. A VPN protects web data from potential hackers and government surveillance by hiding the real IP address of the host and encrypting user's internet traffic.
Basically, the VPN is a computer software that enables internet users to create a secured connection (sends and receives data) over public or shared networks like they're directly connected to the private network.
The potential benefits of a VPN service are;
- It increases privacy level by guarding the real IP address on the Internet.
- It protects user data exchange on a public Wi-Fi network by encryption.
- It can be used to securely connect to a corporate or personal network from far away through the Internet and access local resources.
The answer is The Internet. It is a vast global network that is made up of many smaller interconnected networks. It connects to millions of computer units world wide, in which any computer can communicate with any other computer as long as they are both connected to the Internet. It also made access to information and communication easier.
