The document discusses the key components that make up a computer and how they work together. It includes a video that walks through the steps a computer takes with each mouse click. The components it identifies are the peripherals, input/output subsystem, central processing unit (CPU), programs, and memory. The CPU's job is to fetch and execute instructions, while programs are encoded and stored in memory as 1s and 0s.

Inside your computer - Bettina Bair
How does a computer work? The critical components of a computer are the
peripherals (including the mouse), the input/output subsystem (which controls what
and how much information comes in and out), and the central processing unit (the
brains), as well as human-written programs and memory. Bettina Bair walks us through
the steps your computer takes with every click of the mouse.

physical world and the digital information surrounding us has been getting thinner
and thinner. Designer and engineer Jinha Lee wants to dissolve it altogether. As he
demonstrates in this short, gasp-inducing talk, his ideas include a pen that
penetrates into a screen to draw 3D models and a computer desktop prototype that
lets you reach through the screen to manipulate digital objects. Watch the TED
Talk.
