Establishing Protocol

1. Remote access, more popular as remote desktop/ network has the communication and transmission of information from a shared protocol that enables the remote control of a different PC in either a LAN or WAN. The remote computer is referred as server, while the local computer as client. The protocol is the "language" in which the PCs interact and differs with the software used to set up a remote access relationship. Certain OS has capacity to allow remote desktop, but third-party utilities also provide different features, levels of control and communication protocols.

Communication

2. Remote access needs the installation and configuration of software to make PC for receiving commands as a server. After installing, the resident utility listens to a given incoming port number for any activity from the network and tries to interpret and execute any commands it identifies based on the parameters set up by the application. These commands range from something as simple as cursor manipulation to the actual execution of applications or resetting of system settings as if physically present at the terminal of the remote PC. The PC even needs the configuration and installation of client-side utility to allow remote access. Linking with the server takes various types, like a virtual private network or dial-up access. After connecting, can even see the graphical user interface of the remote desktop, although how the display is handled differs with the kind of remote access software used. The picture shown on the client's side is the same one that would see if at the remote PC. The nature of this interface also means that it supports a PC that does not have a monitor connected as long as a network connection is present.

Factors in Remote Access

3. Remote access is based on the network connectivity among 2 PCs. Issue like a data lag can be a thought due to the amount of information that must be exchanged to manage the graphical user interface on the client end. Firewalls also require to be configured on the server and client sides in case security measures limit any message attempts.
