Analog Vs Digital Phones

  . Phone or telephone is telecommunication device.

  . Converts sound into electronic signals and sends data to longer distances.

  . Transmitted via cables or other transmission media.

  . Manner in which data is being transmitted tells us whether it is analog or digital phone.

  Analog Phones:

        . It uses Analog Technology which converts audio into electronic pulses.

        . These electronic pulses travel until it reach destination.

        . Also called Plain Old Telephone Services (POTS).
        . Used in homes and small business which needs minimum facilites.
        . Offers hold, mute, redial etc.

        . Has less number of keys.

  Digital Phones:

        . It uses Digital Technology which converts audio into binary code 0's and 1's.
        . Used in offices, large business areas which require many facilities.
        . Offers integrity with VoIP (Internet Protocol for voice transmission), voicemail, music on hold, transfer etc.
        . Has many keys.

  Cordless Phones:

         . It uses both analog and digital.

         . Wireless handset uses digital technology to connect to base.

         . Base uses analog technology to transmit sound.

  Analog Vs Digital:

Property	Analog	Digital
Conversion	Audio into electronic pulses	Audio into 0's and 1's
Security	Less	More because it can easily set up encryption
Coverage	Limited Range	Allows more users to use within coverage area
Accuracy	Less	More
Sound Quality	Higher	Low compared to analog due to conversions involved
Clarity	Less	Much clearer signals
Fading	More prone to signal fading	Less prone
Errors	Occurs	Can correct errors that occur during transmission
Cost	Cheaper	Expensive
Flexibility	Relocating requires rewiring	Flexible
Options	Hold, mute, redial etc	Voicemail, VoIP, music on hold etc
