Send text message - format the bytes, send out the bytes, verify they were sentĬPU Variant: GPU - Graphics Processing Unit Run button - "print information," do some math 4 cars does not get you there faster than 1 car Key: having 4 cores is not 4x faster than having 1 core.

Later on, we will complete the picture of how your Javascript code is run by the CPU. When you hit the Run button, the CPU ultimately "runs" your code. When we say that a computer can "add two numbers, a billion times a second". The CPU does the active "running" of code, manipulating data, while the other components have a more passive role, such as storing data. A "2 gigahertz" CPU performs 2 billion operations per secondĬPU - Central Processing Unit - inevitably referred to as the "brains" of the computers."gigahertz" = 1 billion operations per second.RAM and persistent storage which just store data 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)Ĭomputer Hardware - CPU, RAM, and persistent storage

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).
