Remote Control Protocols
CompTIA lists three protocols that are associated with remote-control access:
Remote Desktop Protocol (RDP), Secure Shell (SSH), and Citrix Independent
Computing Architecture (ICA). RDP is used in a Windows environment. Terminal
Services provides a way for a client system to connect to a server, such as
Windows Server 2008/2003/2000, and, by using RDP, operate on the server as
if they were local client applications. Such a configuration is known as
thin client computing, whereby client systems use the resources of the
server instead of their local processing power.
Windows Server products and Windows 7 (as well as Vista and XP) have built-in
support for remote desktop connections. The underlying protocol used to
manage the connection is RDP. RDP is a low-bandwidth protocol used to send
movements, keystrokes, and bitmap images of the screen on the server to the
client computer. RDP does not actually send data over the connection - only
screenshots and client keystrokes.
SSH is a tunneling protocol originally created for UNIX systems. It uses
encryption to establish a secure connection between two systems and provides
alternative, security-equivalent applications for such utilities as Telnet,
FTP, and other communications-oriented applications. Although it is available
with Windows and other operating systems, it is the preferred method of
security for Telnet and other cleartext-oriented programs in the UNIX
environment. SSH uses port 22 and TCP for connections.
Citrix ICA enables clients to access and run applications on a server, using
the server's resources. Only the user interface, keystrokes, and mouse movements
transfer between the client system and the server. In effect, even though
you work at the remote computer, the system functions as if you were actually
sitting at the computer itself. As with Terminal Services and RDP, ICA is an
example of thin client computing.

Reasder Dante from AK says, "Having very little networking experience to begin with, I used
solely this book to pass the CompTIA N+ exam. They few questions I did get wrong where in
sections that I knew I had simply not studied hard enough in. The material is completely laid
out here, just make sure you devote enough time to ALL the sections. I would highly recommend
this book, as I was able to pass with flying colors.
