Answer:
What is remote access?
Remote access is the ability of an authorized person to access a computer or network from a geographical distance through a network connection.
Remote access enables users to connect to the systems they need when they are physically far away. This is especially important for employees who work at branch offices, are traveling, or telecommute.
Remote access enables remote users to access files and other system resources on any devices or services that are connected to the network at any time. This increases employee productivity and enables employees to better collaborate with colleagues around the world.
A remote access strategy gives organizations the flexibility to hire the best talent regardless of location, remove silos and promote collaboration between teams, offices, and locations.
Technical support professionals can use remote access to connect to users' computers from remote locations to help them resolve issues with their systems or software.
One common method of providing remote access is via a remote access virtual private network (VPN) connection. A VPN creates a safe and encrypted connection over a less secure network, such as the internet. VPN technology was developed to enable remote users and branch offices to securely log into corporate applications and other resources.
Users can connect to a remote access server through a dial-up connection or a virtual private network (VPN) connection.
A dial-up connection requires both the server and the client computer to have a correctly configured modem. The client and the server connect over analog public telephone networks. To enhance the security of a dial-up connection, use data encryption, Windows logon and domain security, remote access policies, and callback security.
A VPN connection is made over a public network, for example, the Internet, and uses Point-to-Point Tunneling Protocol (PPTP), logon and domain security, and remote access policies to help secure the transfer of data.
Hope this helps good luck and stay safe always <3
