Welcome to Week 10
In the past, we have covered the 4 basic steps that computers take to process information. These steps are input, processing, output, and storage. We also covered the different kinds of memory that a computer uses, such as random access memory. Random access memory is temporary memory that the CPU uses to process information. The more RAM that a computer has, the more programs the computer can run at the same time. Information that is stored in secondary storage can be retrieved for later use. We call this permanent storage. Additionally, we mentioned that computers communicate in binary code, which are 0's and 1's. The information is then processed in the form of text, images, video, or sounds that we can hear or see through the monitor or speakers.

Direct current and alternating current was also discussed. Every household appliance uses alternating current, which moves in a wave like format. Direct current, on the other hand moves in a straight line. A computer accepts alternating current from your home outlet and then converts it into direct current, which the motherboard, along with the CPU use to process information.

The way that electricity behaves in a computer circuit is directly related to Ohms law. Ohm's law states that Voltage= Current x Resistance. One way to think about this is to think of water going through a pipe. The pressure that pushes electricity across wires is Voltage. The current is the amount of electricity that is flowing through the wires. Finally, resistance is any blockage that restricts the flow of electricity. The higher the voltage or pressure, the more the current flows through the wires.
