Answer

Brief Explanations:

  1. Information doesn't actually travel instantaneously. In digital communication, high - speed electrical or optical signals carry information. The perception of instantaneity comes from the very high speeds of these signals (close to the speed of light in some media) and efficient processing systems.
  2. When a phone receives a message, it first decodes the digital signal (which could be in binary form). Then, software on the phone interprets the binary data as text, images, etc. and sends the appropriate instructions to the display hardware to show the message.
  3. A phone has an image sensor (like a CMOS or CCD sensor). When visible light waves hit the sensor, they cause a photoelectric effect, generating electrical charges. These charges are then converted into digital values (binary numbers) that represent the intensity and color of the light at each point, creating a digital picture.

Answer:

  1. Information doesn't travel instantaneously; high - speed signals and efficient processing give the perception.
  2. Decodes digital signal, software interprets and instructs display.
  3. Image sensor creates electrical charges from light, converted to digital values.
