What is IPv4 ADDRESSES with example ?

IPv4 address Analysis:

An IPv4 address is a 32-bit address that uniquely and universally defines the connection of a device (for example, a computer or a router) to the Internet.

The IPv4 addresses are unique and universal.

Dotted-decimal notation and binary notation for an IPv4 address

Ex.Change the following IPv4 addresses from binary notation to dotted-decimal notation.

Solution

We replace each group of 8 bits with its equivalent decimal number (see Appendix B) and add dots for separation.

Multiplexing and Multiple Access

Multiplexing And Multiple Access : Digital Communications Difference between Multiplexing and Multiple Access: Sr.No. Multiplexing Multiple Access 1 “In telecommunications and computer networks, multiplexing is a process where multiple analog message signals or digital data streams are combined into one signal over a shared medium.” “In telecommunications and computer networks, a channel access method or multiple access method allows several terminals connected to the same multipoint physical medium to transmit over it and to share its capacity.” 2 The multiplexed signal is transmitted over a communication channel, which may be a physical transmission medium. A channel-access scheme is based on a multiplex method that allows several data streams or signals to share the same communication channel or physical media.

Difference in between Time division multiplexing (TDM) and Frequency division multiplexing (FDM)

Difference in between TDM and FDM: This page on FDM versus TDM describes difference between FDM and TDM multiplexing . FDM is the short form of frequency division multiplexing and TDM is the short form of time division multiplexing. In FDM each signal is modulated onto different unique RF carrier frequency and all carrier frequencies are separated significantly so that bandwidth of the signals do not overlap in frequency domain. Figure: Difference in between TDM and FDM
