Remote access is the ability to enter a specific network from another location.
Both methods require a computer with hardware and software for the relevant remote access method. A dial-in connection requires a modem and a telephone number that provides access to the network. To access a network remotely using dial-in access , the user first enters a login ID and password to authenticate the user as an authorized user of that network. The dial-in software then dials the network s telephone number. The telephone line being used becomes a dedicated line for that one user.
