What is the function of optocoupler?
An optocoupler provides galvanic isolation between the sending and the receiving side of an information stream. The signal crosses the galvanic isolation by being transmitted by a light emitting diode (or a similar mechanism), and is received by a light-sensitive device such as a photo diode or resistor. Common uses of opto couplers include the trigger system of triacs and thyristors, electronic devices dealing with high voltage and current. In those systems, the opto coupler protects the sensitive control logic and equipment that manages the trigger signals from the high power load path. Other common uses of opto couplers are in computing, where devices need connecting to enable exchange of data and where galvanic isolation is desired to keep both sides decoupled. Fibre optic data cables are also very similar to an opto coupler. A typical opto coupler has a thin galvanic isolation barrier (a think layer of glass or similar plastic material) between the light transmitting and light receiving sides. A fibre optics "cable" works much in the same way, except the isolating (but light-conducting) barrier is a very long fibre of glass (or a similar material).
What provides essential operating system services?
The BIOS. The BIOS provides services to the OS and the OS provides services to the applications.
What provides power to the internal components of the computer?
In the case of a desktop computer a power supply that in turn plugs into a household outlet provides power to the internal components of the computer. In the case of a laptop or tablet a battery provides power.
What is difference between pulse radar and CW radar?
CW or continuous-wave radar cannot determine range due to the lack of a listening period where the radar signal is silent. Pulse radar has a silent listening period (hence the name pulse radar). Therefore it can determine the range of the object causing the return by counting the elapsed time between transmission and receipt of the echo. The above is not quite correct, Continuous Wave Radar and Pulsed Radar differ by there relationship between the Pulse Width (tau) and the scene size (Swath). CW Radar's determine range by Frequency Modulation (FM) ranging this means that they ramp the RF frequency within the pulse during the transmission and are known as FMCW Radar. Pulsed Radar on the other hand use the pulse timing but can also use the FM Ranging trick to enhanced there signal to noise and reduce there probability of interference or detection/interception. CW radar can deduce range by delaying the transmit signal and mixing it with the receive such that it becomes a homodyne receiver and in such cases it is usual to ramp the RF and perhaps use two aerials rather then just one with a duplexer switch like in a Pulse radar system. Edit- hmm i feel the above answer is bit too complex... i don't think typical person would go as far as concerning FM or Pulse Delay Ranging here's my Answer DIFFERENCES BETWEEN PULSE AND CW RADAR Basis -Transmission Pulse RADAR puts delay between transmitting and receiving periods so the time between transmitted pulse and received pulse is different While CW RADAR, Transmit continuously -Antennas Pulse RADAR may use same antenna for Receiving and Transmitting , when transmitting the receiver is "blanked" and while Receiving the receiver is Activated and transmitter is blanked .. this is done by a device called "Duplexer" CW RADAR typically used 2 Antennas, one for transmit another one to Receive since there are no delay to receive as what usually seen in pulse RADAR -Ranging technique Pulse RADAR may use "Pulse Delay Ranging" to provide Range measurements , Frequency Modulation Ranging may also possible , especially for pulse RADAR that transmit many pulses and have very shot time to "listen" example is FMICW (Frequency Modulated Interrupted Continuous Wave RADAR) While CW RADAR provides Range by means of Doppler based Ranging (FM Ranging)

How is Morse code helpfull?
Morse Code provides a letter-based method of communication by means of any type of signal that can be switched on and off ... light, sound, etc. As such, it can accomodate messages in any language that uses the familiar Roman (English) alphabet. While using the simplest possible transmitting and receiving equipment, it is highly immune to noise, and can succeed over very noisy 'channels'.
