Acts like a brain: follows the instructions in the code.

These three are found in all computers: laptops, smartphones, and tablets. Now let's talk about the three major parts that make up a computer - CPU, RAM, and Persistent Storage. (2-clicks)Д¬omputer Hardware - CPU, RAM, and persistent storage

Also has an angle to blink-speed mode.

Flashlight converts angular position to brightness.

Moore's law makes this application of a chip feasible.Maglite XL200 flashlight has a chip in it.One reason cars work so much better today.The pre-computer control systems did not work so well.Chips are a great, cheap way to build control systems.set off the airbag on high G-forces from collision car engine: vary fuel mix based on temperature Control system: responds to external state.the original iPhone) as well as cheaper computers (less capable computers show up everywhere, like in thermostats and cars). Moore's Law results in more capable computers (compare what an iPhone 7 can do vs. This is quite clear if you look at the cost or capability of computers/cameras etc. More broadly, it captures the idea that per dollar, computer technology (not just transistors) gets exponentially better as time goes along. It is not a scientific law, just a broad prediction that seems to keep working. The increase is due to improved chip making technology. Moore's law (Gordon Moore, Intel co-founder) states that the density of transistors on a chip doubles about every 2 years or so (sometimes listed as every 18 months). Moore's law will probably not go on forever.8x in 6 years may match your phone's capacity increase.Rule of thumb: 8x capacity every 6 years.Example: $50 MP3 player capacity every 2 years: 2GB, 4GB, 8GB, 16GB.(b) is why computers are now in cars, thermostats, greeting cards.or keeping capacity constant, chips get smaller and cheaper every 2 years speed does not double, capacity doubles which is still very useful chips have twice the capacity every 2 years But a cutting edge chip factory costs more than 1 billion dollars Can fit twice as many transistors per chip.Transistors get 2x smaller about every 2 years.Since then, transistors have been made smaller and smaller, allowing more and more of them to be etched onto a silicon chip. The transistor was invented in the early 1950's, replacing the vacuum tube. In particular, a 'bit' (below) can be built with an arrangement of 5 transistors. It is a basic building block used to construct more complex electronic components. The transistor is a 'solid state' device, meaning it has no moving parts. The most common electronic component is the 'transistor' which works as a sort of amplifying valve for a flow of electrons. (See: wikipedia chip) Note that silicon (chips, solar panels) and silicone (soft rubbery material) are different! Modern computers use tiny electronic components which can be etched onto the surface of a silicon chip. Tiny wires connect the chip to the outside. Inside the plastic package is a fingernail sized silicon chip with transistors and other components etched on its surface. Later we'll see a bigger chip with hundreds of pins. This is a small chip with just a few 'pins' of electrical connection. I pulled this out of the e-waste pile at the Stanford CS building, so it's probably kind of old. Here is a silicon chip inside its plastic package. Silicone (soft substance on cooking utensils) Chips are packaged in plastic, with little metal legs.Chips can contain billions of transistors.Microscopic transistors are etched onto silicon chips.Silicon chip - fingernail sized piece of silicon.'Switch' that we can turn on/off with an electric signal One of the most important inventions in history Transistors are 'solid state' - no moving parts Transistor - vital electronic building block.'Hardware' refers the physical parts of the computer, and 'software' refers to the code that runs on the computer. This section will introduce major parts and themes of how computer hardware works. The computer is an amazingly useful general-purpose technology, to the point that now cameras, phones, thermostats, and more are all now little computers. Like piano (hardware) and music (software).

Computers have two main parts: hardware and software.
