What is the difference between AC and DC?

AC means Alternating Current, while DC means Direct Current. When you say alternating current, this means that you can change your direction periodically. When you say Direct Current, this means that the flow of energy is going towards one direction only.

This is a constant voltage circuit. There are some applications right now that will use alternating currents because they would need something that would change and reverse the direction of the energy from time to time.

AC will make it more possible to send high voltages over a longer distance, which is why some people are using this moreover DC, especially with the available applications now.

Remote desktop happens to be a term that is popularly used in referring to a kind of software that is used in connecting to a remote computer in order to run other applications or execute commands on the computer. The commands, clicks, and keystrokes are being sent to the remote computer, and this will send the desktop looks images to the user.

A similar software type that carries out the same function is the VNC, which means Virtual Network Computing. A lot of this software that remote desktop is present in their names are used and fixed to a particular operating system, while Virtual Network Computing happens to be a cross-platform application.

Talking in terms of their performances, remote desktop software is known to frequently perform faster than Virtual Network Computing. In addition, VNC happens to be inherent software that is unsecured, while the remaining remote desktop software is secured already.
