Each year 1.5 million shelter animals are euthanized (670,000 dogs and 860,000 cats). Source: ASPCA. The solution is not to shelter unwanted pets, but to SHUT DOWN THE PET MILLS. Anyone who wants a pet will just have to adapt a great pet from a shelter.

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.
