Describe the meaning and importance of sympathetic tone and parasympathetic tone?

Sympathetic tone refers to the level of activity in the sympathetic nervous system, which prepares the body for physical activity or stress responses. This tone helps increase heart rate, blood pressure, and glucose release to support immediate action. Parasympathetic tone, on the other hand, regulates the body's rest and digest functions, promoting relaxation and recovery. Balancing these two tones is crucial for maintaining overall physiological homeostasis and responding effectively to different situations.


Explain the difference between pulse and tone How does the pulse work compared to tone?

Pulse dialing sends discrete pulses corresponding to numbers when a phone key is pressed, while tone dialing sends out specific acoustic tones. Pulse dialing involves interrupting the phone line's current to make calls, whereas tone dialing generates specific frequencies. Tone dialing is faster and more efficient than pulse dialing, which is becoming obsolete.

Why does a landline give dial tone but a cellphone does not?

When you lift the receiver on a landline telephone, the telephone switching office has to connect your line to special equipment that turns the clicks (on a rotary-dial or pulse-dial phone) or sounds (on a touch-tone phone) into a telephone number so that it can connect your call. The dial tone is an indication to the caller that the system is ready to accept a telephone number. Normally, you get dial tone immediately when you pick up the phone, but in an emergency when thousands of people are trying to make calls simultaneously, you may have to wait your turn before you get a dial tone.* Also, if you wait a long time without dialing a number, the telephone switch will take you off the dialer circuit so that it can use that equipment for someone else's call; that's when you hear the "howler" that alerts you that your phone has been left off the hook.The way that a cellphone dials is completely different. You enter the whole number on the phone and press "send," which sends the number as a packet of digital data on a completely different radio channel from the one that carries your voice. Since you aren't ever connected to a dialer circuit, there's no need to have a dial tone.* In an emergency, when the telephone system is overwhelmed, you should wait to make any non-essential calls. If you must make a call from a landline, pick up the receiver and wait until you get dial tone, even if it takes a minute or more. Do not hang up and pick up again; that will only move you to the back of the queue.

What is touch tone dialing?

Touch Tone was a trademarked name used for the system technically known as DTMF, or Dual-Tone Multi-Frequency, dialing. In DTMF, pressing each key on a telephone dial produces two different tones. Each row and each column of the dial is assigned a specific frequency (pitch) of tone, so the combination of the two tones uniquely identifies the key that was pressed. The telephone switch receives and decodes the tones in order to process the call. This is in contrast to pulse or rotary dialing, in which a series of electrical pulses or clicks are sent through the telephone wire, either by turning a rotary dial or by generating the clicks electronically. The telephone switch counts the number of clicks to get each digit that is dialed.
