Definition - What does Remote Access mean?
Remote access refers to the ability to access a computer, such as a home computer or an office network computer, from a remote location. This allows employees to work offsite, such as at home or in another location, while still having access to a distant computer or network, such as the office network. Remote access can be set up using a local area network (LAN), wide area network (WAN) or even a virtual private network (VPN) so that resources and systems can be accessed remotely.
Remote access is also known as remote login.
Techopedia explains Remote Access
Remote access can be established via a line that runs between a computer and a company's local area network (LAN). A connection can also be established between a company's LAN and a remote LAN using a dedicated line. This type of line provides faster speeds but has the drawback of being more expensive.
Another method for performing remote access is by establishing a VPN, a network that usually uses the Internet to connect remote sites and users together. This type of network uses encryption and tunneling to access a company's network. This can be a great choice for a relatively small organization. Other means of establishing remote access include the use of an integrated services digital network, wireless network, cable modem or digital subscriber line.
To establish a remote connection, both the local machine and the remote computer/server must have remote-access software. Alternatively, there are service providers that offer remote access via the Internet.
