I can disassemble and reassemble a computer.
I can describe the function of basic PC components.
You will be asked comprehension questions to identify parts of a computer from their images, what their primary purpose is, and what their common problems are
You will be observed disassembling and reassembling a computer and checked that you can identify all the components and that you can reassemble the machine correctly
Imagine a person juggling while singing an old song from their childhood. Part of the juggler's brain is tracking the motion of each ball and the timing of each throw. Another part of the juggler's brain is recalling the song. His stomach is fueling his muscles. His nervous system is communicating controls from his brain to his arms. His eyes are taking in information. His voice is outputting the song. We'll use this as a reference as we go over hardware.
CPUs or processors do math. They are a super complex series of logic gates made unbelievably small. What are logic gates? Imagine a wire with two light switches in a row. Since both switches are on the same wire, both need to be flipped to the ON position in order for power to flow through the line. That's an AND gate. If the wire split into two instead and each fork had its own switch, that would be an OR gate as only one or the other has to be enabled for power to flow. Processors have millions and millions of these complex arrangements made in microscopic sizes.
According to our analogy, the CPU is the part of the juggler's brain that's calculating the path of each ball while also managing all the other signals through his brain. It doesn't cover all the functions of the brain in our analogy, but it is at the center of the comparison.
CPUs use a lot of power and generate heat. Metal wires create a little resistance as electricity flows through them and that energy turns into heat. You must manage the heat that gets created by your CPU using a fan or other cooling system. If your computer collects a lot of dust, it will insolate
If a CPU is older it means it could be generating more heat while executing fewer commands. And if the CPU is slow, that means it must be connected to a whole bunch of other parts that are older and slower too.

No one writes code totally from scratch. All programmers use a variety of preexisting systems that allow for easier development. We write code that interacts with other layers. That's an API or Application Program Interface. We can interact with our operating system, helpful resources or other apps.
The BIOS or Basic Input/Output System is firmware. It's something built right into your motherboard. It helps boot your computer up and gives something for the operating system to run off of.
The OS is a big deal. It serves as a vital intermediary between software and hardware. Instead of having to program every little operation for each device in our computer, we can just use the commands provided by the operating system.
The interpreter allows us to execute our written Python code. It's our interface with the Operating System which is in turn interfacing with our hardware.
Part of what makes Python so great are all the tools and frameworks available. Want to build a web application? Use Flask or Django and you'll be up and running in minutes. Do you want tools for data analysis? Machine learning? Robotics? There's an ocean of open-source tools ready to give your app superpowers.
In case you're curious and don't mind a little challenge, learn about the and how computer engineers have gotten around it.
