Classroom Spy is a simple yet effective classroom monitoring program. It lets a teacher see the live screens of all his students' computers sitting in front of his own PC (monitor and control what they are doing remotely, without having to walk around in the classroom). Or the other way round, teacher can share his computer screen with all the students' (for ease of giving lessons).

Spy Note is a free Android RAT (Remote Administration Tool/Remote Access Trojan) program developed based on Java. Its Server is written in Java, and the Client controller is written in Visual Basic .NET. After installation on an Android device, Spy Note will automatically remove its on-screen icon from victim's device.

With the popularity of Linux applications on the server side, Linux system management increasingly relies on the remote control. Among various remote login tools of the same type, PuTTY absolutely deserves to be called one of the best that are very suitable for remotely administrating Linux servers by webmasters or administrators.

Due to the increasing complexity of current Internet/Intranet environments, a variety of factors such as firewall, router, or broadband provider (ISP) often leads many remote control software based on the traditional 'direct connection' technology (like Microsoft Remote Desktop) to connect/operate very slow or even connection fail. Even the industry's strong performer TeamViewer also is becoming slower and slower.

No doubt, TeamViewer is an excellent all-in-one solution for remote control and online meeting. Sure there are also lots of similar good software, such as AnyDesk, ScreenConnect, Anyplace Control, PCAnyWhere, etc. But finally I would say TeamViewer does the best on a whole level.
