How to use Windows Remote Desktop?

On a local network, it's easy to connect to a remote PC – type  its name or IP address into the Remote Desktop Connection box. But when you're trying to connect to your remote PC via the internet, things get a little more complicated.

First, make sure the Windows firewall isn't blocking Remote Desktop. You can check this by opening up the Windows Firewall section of the Control Panel and selecting Allow apps to communicate through Windows Firewall. Scroll down and make sure that there's a tick next to Remote Desktop.

Next, you'll need to make a few configuration changes to the router where the PC to which you wish to connect is located. This is usually done by connecting to the router via your web browser, using the IP address of your local gateway as the address. You can find this by opening a command prompt and typing ipconfig. This will also give you the IP address of the PC you need to connect to. Locate your router's port forwarding options and forward TCP port 3389 to the IP address of the PC to which you want to connect.
Remote Desktop ConnectionYou need to know the external IP address of the PC to be accessed. To do this, open up a web browser on that PC and browse to a service such as myip.dk. This will tell you the address you need to type in to the Remote Desktop Connection dialog box when you want to connect to your PC via the internet. In many cases, this external IP address is subject to change. To avoid having to rediscover the address every time it changes, subscribe to a dynamic DNS service such as no-ip.com.
This will give you a memorable domain name to which you can connect, and will keep track of any changes to your external IP address. Many routers have built-in support for dynamic DNS, so have a look in your manual and select one of the services supported by your router.

You should now be able to connect to your PC both from your local network and via the internet.

5 Reasons Schools Still Need Desktop Computers

1) Processor Power
Schools that offer classes in video editing, engineering or CAD drawing need computers with scads of power because the software required for those classes is processor-intensive.

2) Screen Size
The classes that benefit from the powerful processors also tend to benefit from large computer screens.

3) Ergonomics
Screen size is essentially an ergonomic issue, but it's not the only one. Some schools are sticking with desktops so they have more control over the placement of the monitor and keyboard, and to provide students with full-sized keyboards with integrated number pads.

4) Wired Connectivity
Those engineering and graphics classes are demanding. Not only do they require powerful processors and large screen sizes, but they also generate huge files. When those files need to be transferred over the network, wireless connections are often too slow or unreliable.

5) Dedicated Usage
The school has interactive whiteboards in each classroom, and teachers used to connect their laptops to the interactive whiteboards to display learning materials to their class.
