What Is RDP?
Definition
What is an RDP? Remote Desktop Protocol (RDP) is a secure network communication protocol designed for remote management and remote access to virtual desktops, applications, and RDP terminal servers.
RDP allows network administrators to remotely diagnose and resolve problems encountered by individual subscribers. RDP supports most Windows operating systems and Apple macOS. Now, you can continue to read this post from MiniTool to get more information about the remote desktop protocol.
Features
The features of the remote desktop protocol are as follows:
Encryption
Smart
Authentication
Bandwidth reduction
Resource sharing
Function
Do you know the functions of the remote desktop protocol? It can use multiple displays and can disconnect temporarily without logging off. It also allows redirection functions such as audio and printing.
RDP can support up to 64,000 independent channels for data transmission. The 128-bit key can be used to encrypt data, and the data transmission rate can be optimized in low-speed connections by the bandwidth reduction function.
How Does RDP Work?
After knowing “what is RDP”, let’s see “how does RDP work”. The RDP protocol is designed to provide remote access through port 3389. An RDP-enabled application or service packages the data to be transmitted and Microsoft Communications Service directs the data to the RDP channel. From there, the RDP data is encrypted by the operating system and it is added to the frame so that it can be transmitted.
The RDP protocol activity is handled by the Terminal Server Device Redirector Driver. The driver consists of subcomponents such as the RDP driver (Wdtshare.sys), which handles the encryption, compression, user interface, transmission, and framing. The transport driver (Tdtcp.sys) is responsible for packaging the protocol so that it can be sent over the TCP/IP network.
