Binary language consists of 0 and 1 and electrical switches can be flipped on and off between 1 or 0 Why do computers use 0s and 1s to process data? Computers only understand on and off and 0s and 1s represent those stages. What were the first switches used in computers? Vacuum tubes act as switches by allowing or blocking the flow of electrical current What do personal computers use as switching devices? Transistors and integrated circuits to make them smaller and faster What are transistors?

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
