What is CSMA/CD?
CSMA/CD is a modified version of CSMA.
A scheme known as carrier sense multiple access with collision detection (CSMA/CD) governs the way the computers share the channel. This scheme is relatively simple compared to the token ring. When one computer on the network wants to send some data to another computer, the following algorithm [...]
Frames are the format of data packets on the wire.
There are several types of Ethernet frame:
Original Ethernet Version I (no longer used)
The Ethernet Version 2 or Ethernet II frame, the so-called DIX frame (named after DEC, Intel, and Xerox), this is the most common today, as it is often used directly by the Internet Protocol.
Novell’s [...]
The following sections provide a brief summary of all the official ethernet media types. In addition to these official standards, many vendors have implemented proprietary media types for various reasons—often to support longer distances over fiber optic cabling.
Many Ethernet cards and switch ports support multiple speeds, using auto-negotiation to set the speed and duplex for [...]
Ethernet is a frame based technology which defines wiring and signaling for the physical layer, and frame formats and protocols for the MAC (Media Access Control, data link layer). Ethernet is mostly standardized as IEEE’s 802.3.
Ethernet, by far is the most widely used LAN standard. Every peer node on the network connected using ethernet has [...]
