Working of Ethernet at the Physical Layer
Ethernet was first implemented by a group called DIX (Digital, Intel, and Xerox). They created and implemented the first Ethernet LAN specification, which the IEEE used to create the IEEE 802.3 Committee. This was a 10Mbps network that ran on coax and then eventually twisted pair and fiber physical media. The IEEE extended the 802.3 Committee to [...]
Working of Ethernet Frames on Data Link Layer
The Data Link layer is responsible for combining bits into bytes and bytes into frames. Frames are used at the Data Link layer to encapsulate packets handed down from the Network layer for transmission on a type of media access. The function of Ethernet stations is to pass data frames between each other using a group of bits known as a MAC frame [...]
Working of Ethernet at the Data Link Layer and Ethernet Addressing
Ethernet at the Data Link layer is responsible for Ethernet addressing, commonly referred to as hardware addressing or MAC addressing. Ethernet is also responsible for framing packets received from the Network layer and preparing them for transmission on the local network through the Ethernet contention media access method. Ethernet [...]

What is Parallel and Serial Physical Communication
In a parallel Physical layer arrangement, multiple communications paths lie between communicating parties (see the top half of the Image shown below ). Typically, all but one of the paths is used for data transfer; a single path is reserved for the transfer of timing information between the sender and the receiver. As such, multiple data units [...]

Hindrances to High-Speed Data Transfer
Electricity flowing through a cable is nothing more than electrons moving inside the cable and bumping into each other—sort of like dominoes falling. For a signal to be received properly by the receiver, enough electrons must make contact all the way through the cable from the sender to the receiver. As the frequency on a cable (and consequently [...]
What Factor Slows Down Your Data over the Network Cables
The amount of data that even simple unshielded twisted-pair cabling can transfer has come a long way over the past dozen or so years. In the late 1980s, many experts felt that UTP cabling would never support data rates greater than 10Mbps. Today, data rates of 1.2Gbps and higher are supported over cable lengths approaching 100 meters! And UTP may [...]
Difference Between Simplex, Half-Duplex and Duplex
Below Figure illustrates three possible send-receive configurations in common use at the Physical layer: a simplex send-receive relationship, a half-duplex send-receive relationship and a duplex (sometimes called full-duplex) send-receive relationship. In a simplex send-receive relationship, one partner can transmit and one partner can receive, [...]
