DOS originally didn’t even support directories but was using / for command line arguments. They didn’t want to change the option character and break stuff so they went with \ as the directory separator.

DOS wasn’t originally created by Microsoft. They bought the OS from computer shop in Seattle.

Which block of private IPs your local network uses depends on how your router/DHCP server is configured. If you’re using the standard router your ISP provided then whatever default settings on that will determine your local subnet.

StackOverflowException was unhanded

A watt is 1 Joule per Second (1 J/s). E.g. Every second, your device draws 1 Joule of energy. This energy over time is called “Power” and is a rate of energy transfer.

A watt-hour is (1 J/s) * (1 hr)

This can be rewritten as (3600 J/hr) * (1 hr). The “per hour” and “hour” cancel themselves out which makes 1 watt-hour equal to 3600 Joules.

1 kWh is 3,600 kJ or 3.6 MJ
