Answer / veeramani
Oscillators are connected externaly with the
microcontroller to provides high frequency signal to the
oscillator circuit in the microcontroller. The oscillator
circuit provides the clock signal to the microcontroller.
that's it.

Answer / nitya
in MC all operations are processed upon trailing or leading
edges.because MC has several parts.Each parts are
constructed using Flip-Flop which needs clock for
triggering.

The main purpose of the oscillator in PICmicro
microcontrollers,
or almost any other microcontroller, is to
provide a reliable clock for the controller processes. At
the most basic level, the clock provides a timing interval
to account for circuit rise times and to allow data to
stabilize before that data is processed. This is a
"synchronous" process. The clock also provides an
opportunity for the programmer to perform time keeping
of several types. In the PICmicro, the clock also drives
hardware dedicated to timekeeping. The applications
may include keeping “real time”, or timing sensitive
processes
such as serial data communication. The accuracy
of these timing applications is dependent upon the
accuracy of the clock oscillator

Oscillators are connected externaly with the
microcontroller to provides high frequency signal to the
oscillator circuit in the micro controller. The oscillator
circuit provides the clock signal to the micro controller.
usually "PIEZO CRYSTAL OSCILLATORS" are used in micro controllers.

Answer / chitti
its mainly used to control any process in micro second ,so
clock timer is very important without waiting for input
from any source.oscillator produces the output even without
any input signal and give high freq at initial input for
processor.
Is This Answer Correct ? | 10 Yes | 3 No |
Answer / sivaraman
Main purpose of oscillator is to generate pulse which is
used to synchronize all the circuit(ADC,TIMER etc) in
microcontroller. without pulse, the instructions will not
execute. tats it

Answer / waseem latif
To provide signals of desired frequency to the Microcontroller
Is This Answer Correct ? | 2 Yes | 0 No |
Answer / nishanthi
For the frequency of operation of a microcontroller
Is This Answer Correct ? | 7 Yes | 6 No |
Answer / jigneshkumar ajani
every mc require the frequency, without freq it will not
work so here we can use the crytal where freq. is devived
by 2 e.g. 24/2= 12 so we got that 12 voltage for mc.... and
operate difernt parts of mc.......

how to prepare for csir interview
.We want to compare the performance of a single threaded disk server with a multithreaded 1. Suppose the server takes 25 ms to receive a request for work from client, dispatch the request for processing and actual data request processing when reqd. Data is in main memory. If the reqd. Data is not in the main memory a real disk operation is needed and an additional 75 ms are reqd. On the average. On the average 25% of the clients requests access the disk. During the disk I/O period the thread waits. Assume that there is no other process in system when the server is running. How many requests can the server handle per second if its a)single threaded b)multithreaded
