Final answer:
RDP differs from Telnet and SSH primarily in that it provides a graphical user interface for interacting with the remote desktop, while Telnet and SSH are text-based command-line interfaces. RDP is mainly used in Windows environments, whereas Telnet and SSH are used across different operating systems. Moreover, SSH is more secure than Telnet as it encrypts the data transmitted.
Step-by-step explanation:
The Remote Desktop Protocol (RDP), Telnet, and Secure Shell (SSH) enable remote access into a computer system for various purposes, such as maintenance and retrieval of data. What separates RDP from Telnet and SSH is primarily the graphical interface capability that RDP provides. Unlike Telnet and SSH, which are text-based and predominately interact with the command line, RDP allows users to see and interact with the remote desktop environment in a graphical way. This makes it ideal for performing administrative tasks that require a GUI, such as running graphical applications on the remote machine.
Additionally, RDP is mostly used in Windows environments, while Telnet and SSH are used in various operating systems, including Unix and Linux. However, it's important to note that Telnet is considered insecure because it does not encrypt the data transmitted, which can lead to security vulnerabilities. In contrast, SSH provides a secure channel over an insecure network by using encryption, making it preferable for secure data transmission.
