The 8051 has two 16 bit timer. This two timers are basically a 16 bit register. Which is incremented based on the clock pulse applied on it. The timers are accessible to programmer through the corresponding sfr registers. The main three function of counters are: 1. Producing a delay for a definite time. 2. Counting the transitions on an external pin. 3. Generating baud rates for the serial port.
