What is the difference between pipes and sockets? Why does Unix use pipes for interprocess communication?
Both pipes and sockets handle byte streams, but they do it in different ways…
pipes only exist within a specific host, and they refer to buffering between virtual files, or connecting the output / input of processes within that host. There are no concepts of packets within pipes.
sockets packetize communication using IPv4 or IPv6; that communication can extend beyond localhost. Note that different endpoints of a socket can share the same IP address; however, they must listen on different TCP / UDP ports to do so.
Usage:
Use pipes:when you want to read / write data as a file within a specific server. If you’re using C, you read() and write() to a pipe.
when you want to connect the output of one process to the input of another process… see popen()
Use sockets to send data between different IPv4 / IPv6 endpoints. Very often, this happens between different hosts, but sockets could be used within the same host
BTW, you can use netcat or socat to join a socket to a pipe.

How does a potentiometer work as a variable resistor in Arduino projects?
Well, basically the potentiometer will act as a variable resistor.
When you turn the knob, the resistor will increase or decrease,
which will also increase or decrease the voltage on the analog pin to which the potentiometer is connected.
So, with this example, the Arduino Uno has a max voltage of 5V.
We are have a story with south korea customer for inductors components
we are supplier for inductors components from chinese send to south korean for many years,
and has accumulated more customer from the oversea market.
since our company was established 2005,
we are do for kinds of products and service for Asia, USA, middle east customer and south american customer.
since 2018, we are slow to touch the south korea market and feel theirs hosptialibty.

What are the properties of crystals that make them useful in electronics?
Crystals that conduct electricity
Quartz crystal is the most widely used crystal when it comes to conducting electricity. It’s resistance to wear and heat, added to its ability to regulate electricity, makes it a highly valuable substance for technology engineers.
