ABSTRACT
This chapter continues the discussion by focusing on a service that allows a user to access and control a computer from a remote location. The basic idea of remote login has been extended to provide remote access to modern devices. The computer industry uses a variety of terms to describe remote access on a modern system, including remote desktop, screen sharing, and remote desktop connection; the people will use the term remote desktop. For example, both Windows and MacOS include remote desktop software. In addition to operating system vendors, third-party vendors also offer remote desktop software. Because early computers used textual interfaces, the first remote access mechanisms, known as remote login mechanisms, sent keystrokes to a remote system and displayed the text that the system returned. The goal of all remote access systems is straightforward: provide a user with the illusion of working directly on a remote computer.
