[Answer] A netowrk is connected following the IEEE 802.3 specifications. Which of the following best describes when a device can transmit messages?

Answer: The device listens to detrmine if the transmission media is free.The IEEE 802.3 committee describes the CSMA/CD media access method. Devices listen to the networks to determine if the transmission media is free before transmitting.

A netowrk is connected following the IEEE 802.3 specifications. Which of the following best describes when a device can transmit messages? Ethernet (/ ˈ iː θ ər n ɛ t /) is a family of wired computer networking technologies commonly used in local area networks (LAN) metropolitan area networks (MAN) and wide area networks (WAN). It was commercially introduced in 1980 and first standardized in 1983 as IEEE 802.3 .Ethernet has since been refined to support higher bit rates a greater number of nodes and longer link distances ... CAN bus - Wikipedia Mon Dec 17 2001 · The MAC and LLC layers of IEEE 802 networks such as 802.3 Ethernet 802.11 Wi-Fi and 802.15.4 ZigBee operate at the data link layer. The Point-to-Point Protocol (PPP) is a data link layer protocol that can operate over several different physical layers such as … Frame Relay is a standardized wide area network (WAN) technology that specifies the physical and data link layers of digital telecommunications channels using a packet switching methodology. Originally designed for transport across Integrated Services Digital Network (ISDN) infrastructure it may be used today in the context of many other network interfaces. Thu Apr 14 2005 · A passive optical network consists of an optical line terminal (OLT) at the service provider's central office (hub) and a number of optical network units (ONUs) or optical network terminals (ONTs) near end users. A PON reduces the amount of fiber and central office equipment required compared with point-to-point architectures. A passive optical network is a form of fiber-optic access … In computer networking the maximum transmission unit (MTU) is the size of the largest protocol data unit (PDU) that can be communicated in a single network layer transaction. The MTU relates to but is not identical to the maximum frame size that can be transported on the data link layer e.g. Ethernet frame.. Larger MTU is associated with reduced overhea...
