The IC You speak of, commonly referred to as a 555, is a multivibrator. Simply put, it can be configured to produce voltage pulses in some order.
In the case of a buzzer circuit, it is used to vibrate with a certain frequency - this frequency is then driven to the speaker and is heard as the 'buzz'. And thus, it's a frequency source.

The 555 timer IC is a device that can create various kinds of time delays in a circuit. It uses a threshold pin that is typically connected to an RC circuit. Depending on how it is connected, it can operate in one shot mode (monostable), astable mode (retriggerable), or schmitt trigger mode.
Sure. If you want sound when the circuit is energized, use a buzzer. If you want a visual indication when the circuit is energized, use an LED.
The 555 IC timer is typically measured in units of time, such as microseconds (ยตs), milliseconds (ms), or seconds (s). It can be used to generate precise timing intervals for various applications.
i do not know what an astable circuit does thats why i aksed

The 555 IC is a universal timer circuit. Via the addition of external components (resistors, capacitors) the designer can generate various timing waveforms.
The 555 timer IC is an integrated circuit ,that is used mainly in a variety of timer, pulse generation, and oscillator applications. It can be used to provide time delays.
The 555 IC timer does not have a clock.
A 555 IC is a timer. You can use this for many purposes. It can be used to create different wave shapes (sawtooth, square wave), different tones for an audio circuit, among other things. Search for the data sheet for this, and it will give detailed drawings and explanations. In general, this is the best way to find out about a particular IC.
555 is an arbitrarily assigned part number for a general purpose programmable timer IC. The number itself has no special meaning.
556 is a dual version of 555 single timer.
The 555 is a timer, not a counter.
To bypass Resistor Rb to get less than 50% duty cycle.
I'd say the most popular is the 555 timer IC. It was released in the early 70s, and is still produced in huge quantities today. It is a simple IC, and is usually used as a beginner IC project.
