An oven does some heat transfer by convection. (Conduction and radiation also play a part.) In a conventional oven, hot air will "move around" to a degree inside the oven. There will be some thermal air currents set up, and air movement will carry some thermal energy from the burner or heating element to the item being heated.
In a convection oven (and please note the adjective used there), we find that a fan runs to circulate air around the interior of the oven (called the cavity). The fan moves air (as you probably guessed) to more evenly heat that space and speed up the heating (cooking) process.

A convection oven moves the air, a microwave does not.
A convection oven moves the air, a microwave does not.
The difference is in the features. A regular microwave only features the normal microwave functions. However, a convection microwave oven also has a built-in convection oven in it.
While microwave technology allows you to cook food quickly, the white Whirlpool GH 7208XRQ convection oven includes microwave as one of its features of convection, microwave, steamer, and oven; therefore essentially making the convection oven a more functional kitchen appliance.
I bought a microwave-convection oven at Sears, but you can find them at any good-sized appliance store.
Convection ovens contain a fan, which is used to circulate the heated air around the item being cooked inside the microwave oven. This allows the food to be cooked much faster, while at the same time cooking the food at a lower temperature. The temperature used for cooking in a convection oven is about 20% less than in a regular microwave oven.
You can make a pizza or cake in your microwave oven without a convection mode, but the results may not be as desirable.
You can find some more information regarding convection ovens here: http://www.ehow.com/about_5438666_convection-oven-vs-microwave-oven.html It gives an overview of the differences between the more commonly used microwave ovens and convection ovens.
A convection and microwave combination oven is an appliance that combines the functions of both units in just one piece of equipment. This appliance will look much like a microwave oven, but will have conventional resistance (electric) heating elements in it as well as the little fan to provide the convection. This unit will function in either capacity, and about the only drawback is that the convection oven has a limited volume. Bon appétit!
Your microwave oven has "combination" features, most likely a combination of microwave and convection cooking. Consult the user manual for your specific oven to find out how to use these features.
Yes, Pyrex can be used in the microwave as well as conventional oven.
