Answer:
A computer is defined as an electronic device for storing and processing data, typically in binary form, according to instructions given to it in a variable program.
Four features of a computer would be CPU, GPU, Memory, and Motherboard.
This is the binary system. Numbers are easily translated from binary simply by each binary number in a bit of information has an exponential value. You can translate binary to words because each set of 8 0s and 1s can be translated into numbers which are labeled in a system called asscii. For each number there is a charecter or symbol associated. for example:0000 0011 would translate to 3 and in asscii that 3 would translate into a G. therefore 00000011 would be translated twice by the computer if you hit the g key on your keyboard until a G was displayed on your screen.
I do all you have to do is hook the green screen to your computer and change the back ground so for an example if you are at home you can put yourself in space
