An infinite loop is a loop whose condition is never satisfied.
Eg.
Bool isRunning = true;
while(isRunning)
{
Console.WriteLine("running");
}
this loop will never ends (infinite loop)

[Nelson Joseph]

infinite loop never ends.
e.g

for(;;)
{
...
}

(or)

while(1)
{
}

[horace1]

when programming embedded systems infinite loops are used all the time. e.g. when switched on a river level monitoring system goes into an infinite loop checking the water level and reporting regularly.
The following is a fragment of code from a USB device (which can be connected to a PC USB port) based on a Microchip PIC24FJ64GB002 microcontroller

    InitializeSystem();        // initialise USB and IO devices
    while(1)
    {        
        USBDeviceTasks();     // poll USB interface for activity
        ProcessIO();        // process any device specific IO        
    }
 

in addition one also tends to have a watchdog timer which if the device gets into lockup state will restart the system.
