What is Remote Desktop Protocol (RDP)? Usage

Remote Desktop Protocol (RDP) happens to be a protocol, or a practical standard, for making use of a remote desktop computer. This kind of software able to use numerous dissimilar protocols counting RDP, Virtual Network Computing (VNC) and Independent Computing Architecture (ICA), but RDP use to be the most usually used protocol. Buy RDP protocol that was originally released by Microsoft. It is available for most Windows operating systems, but it can also be used with Mac operating systems.

What does “remote desktop” mean?

Remote Desktop use to refer to the ability of connecting and using a remote desktop computer from a distinct computer. Remote desktop users able to use their desktops, open as well as edit files, and use applications by way of if they actually were sitting at their computer. Employees often use remote desktop software to access their workstations when traveling or working from home.

Access to the remote office is very different from cloud computing, although both allow employees to work remotely. In cloud computing, users access files and applications that are stored in the cloud, or more specifically in cloud servers. Cloud computing is sometimes easier to use and more efficient to implement for employees working remotely, but many companies have not migrated to the cloud, or cannot for security or regulatory reasons.

How does RDP work?

Think of a drone or a remote control baby carriage. The use of RDP is somewhat similar: the user’s mouse movements and keystrokes are transmitted remotely to their desktop computer, but over the Internet rather than radio waves. The user’s desktop is displayed on the login computer, as if the employee were sitting in front of their own computer.

The RDP protocol opens a network channel dedicated to sending data between the connected machines (the remote office and the computer used for the connection). It always happens to use network port 3389 for this same. Mouse activities, desktop display, keystrokes over the remote keyboard, and all rest of the essential data use to be sent over this channel over IP / TCP. RDP also encrypts all data to make connections over the public internet more secure.

Since keyboard and mouse activity must be encrypted and transmitted over the Internet, which takes a few milliseconds, and the desktop screen must be returned to the user, slight delays tend to occur. For example, if a user double-clicks an application to open it, the “double-click” might take a few milliseconds because the user’s action is passed to the desktop before being executed. Then, when opening the application, another short delay may occur while the display is transmitted to the user.

What are the advantages and disadvantages of using RDP?

RDP has several advantages. One of the advantages is that it doesn’t require a VPN. It keeps the data also stored safely on the desktop of the user, in place of keeping it on cloud servers or the unsecured personal devices of the user. In addition, RDP enables companies with an on-site IT infrastructure to enable their employees to work from home.

However, with RDP, users can experience latency, especially if their local internet connection is slow. This latency can frustrate remote workers and reduce their productivity. RDP also has serious security holes that make it vulnerable to cyber-attacks. (Learn more about RDP security).
