If the CPU is running, but the monitor has no signal, there could be an issue with the cable that connects the CPU to the monitor. There could also be a problem with the VGA card, or the RAM.
Please check the cables connected between your CPU and monitor are not broken and fixed correctly. If cables are ok and connected correctly, check if CPU is running. All new monitors are capable of detecting input signals from multiple sources, if only one signal source is present when monitor is powered on. Else manually change which source to be used by monitor for display.
the input signal is carried to CPU by having a binary numbers.
No.
You probably have a graphic card installed and have the cable connected to the integrated card or vice versa.
Get a monitor with an HDMI or analog input and connect it to a cable TV tuner.

PIO uses the port access instructions of the CPU to receive or send data. That is also known as polling, since you have to constantly use the CPU to monitor a particular port address. Interrupt driven would use the IRQ controller to access things. The CPU still does the work, but the interrupt calls on the CPU rather than a currently running program doing so.
The function of a computer monitor is to display the results of processed data from the CPU. Touch screen monitors are both input and output devices.
CPUs are the most reliable piece of hardware in a PC. They rarely fail. If there appears to be a problem with a CPU monitor, it is likely due to an error in installing the CPU monitor, such as plugging in the correct cables. One should ensure that everything else in the computer is running correctly before concerning with the CPU.
The CPU (Central Processing Unit) is an input and output device. Think of it as the brain of your computer. You give it commands by typing on the keyboard, moving the mouse, etc (input) and the CPU processes this command and tells the computer to display text on the monitor or move the cursor to a new position (output)
That is a message from your monitor saying it couldn't find any signal to display so it is turning off. It could be the CPU, the memory, the motherboard, or anything connected to it. Disconnect all the drives, pull any expansion cards, and leave only the keyboard and monitor plugged in and see if it will POST.
