The CPU, or central processing unit, is the hardware that takes most of the load when running a program. It will perform complex calculations and execute every instruction as the program continues.
The GPU, or graphics procession unit, is the hardware that could also play a major roll in calculating the instructions to execute a program, though this depends on how graphically intensive the program is. For example, games would use a lot more GPU power than say a simple calculator application.
<u>Twitch</u> is an online service that comprises original content in the form of live or recorded streams and it is typically focused on showing various individuals that are playing video games.
Twitch is an online (web) service that was launched in June 2011 and it derived its name from twitch gaming such as video games that are mainly about fast action and the use of reflexes by the game players.
The main purpose of Twitch is to avail game players the opportunity to stream or show live or recorded videos of themselves playing video games.

Most apps for <u>learning</u> a new language are for educational purposes and are most likely an education type of app.
convection requires a medium is not the main difference, it is simply the most obvious aspect of what is a fundamentally different mechanism for transfering energy. Convection is the transfer of energy by movement of a medium, whereas radiation is the transfer of energy by, well, thermal radiation. Conduction also requires a medium, but, again, it is a fundamentally different mechanism than either convection or radiation; in this case it is the transfer of energy through a medium.
Unfortunately, analogies are hard but if you can visualize the particles involved, it would help. Picture the red hot iron you mentioned. On a molecular level, the material is emitting lots and lots of photons (hence why it is glowing red). The creation of these photons takes energy; energy from the heat of the iron. These photons leave the iron, pass through the environment, and eventually collide with some other object where they are absorbed and deposit their energy. This is radiative heat transfer. If that energy is deposited on your retina or a CCD (like in a digital camera), an image forms over time. This is how infrared goggles work and they would work equally well in high vacuum as here on earth.
In conduction, the next simplest example, there is no generation of photons (physics nerds forgive me for the sake of simplicity). The individual atoms in the object are vibrating with heat energy. As each atom gains energy from it's more energetic neighbors, so it gives up energy to its less energetic ones. Over time, the heat "travels" through the object.
In convection, the molecules of gas near the object gain energy, like in the conduction case, but those same molecules that gained energy then travel through the environment to some other location where they then give off their heat energy.
In summary:
radiation = generated and absorbed photonsconduction = molecules exciting their neighbors succesivelyconvection = molecules heated like in conduction, but then move to another location
