I am so confused,i have no idea what these are

When resizing an image for display on a computer monitor you should reduce its resolution to _____?

An audio file that is played as it arrives from the internet without saving it to a users computer is called _____?

One answer to the first one is in the settings on your computer. On my computer, the smallest settings (resolution) is 800 x 600 pixels.

I think the second one is called "wave" file because it has an extension of .wav at the end of the file name.

There are undoubtedly others, but this seems to be the most commonly used.
