What is a robot ,barcode reader, expansion slots, motherboard, system unit ,ram, rom, processor, arithmetic and logic unit

A robot is a machine capable of carrying out complex orders.

A barcode reader is a device that reads barcodes, which can be found on most brick-and-mortar store products.

I don't know what you mean by expansion slots.

A motherboard is a device that houses your RAM, your CPU, and your GPU. It also does other things as well, but those are the most important.

For the system unit, I'm going to assume you mean the case. The case is what holds the motherboard and the power supply. It also stores slots for additions, such as CD readers and thermometers (the thermometers are used to make sure that the computer doesn't overheat)

RAM, or random access memory, is temporary storage that gets dumped. It's used for programs that are currently running.

ROM is read-only memory, used mostly in video game cartridges. It can only be modified slowly, or sometimes not at all.

A processor is what processes information. They have cores, and the cores have threads, but explaining that would take a while.

I don't know the others, though.

given the lack of choices, i'm gonna wing it and say that pushing your car off a cliff might not be the best idea. your car might sustain damage from the fall and will probably result in the car being too damaged to jump start.

if that's not good enough, avoid filling the car with bees. bees might get agitated when trapped or during the moving process, and might result in death or painful stings that will make jump starting your car very difficult. but in the event that you do choose to fill your car with bees, remember to wear protective gear!
