registering a bit of 1 on Ethernet can be as low as 2.5 volts or even 1 volt. Why is this so low when the capacity for transmitting electricity on the copper wire is so high? Use your textbook and Internet research to support your answer. Because the voltage used to transmit data needs only be high enough for the receiver to detect it. Making the voltage higher would make the receiver electronics more difficult. 4.1.3 The voltage for registering a bit of 1 on Ethernet can be as low as 2.5 volts

telephone wire and consists of insulated strands of copper wire twisted together. There are two versions of twisted pair cable: Shielded Twisted Pair (STP) and Unshielded Twisted Pair (UTP). STP is commonly used in Token Ring networks and UTP in Ethernet networks where it is referred to as "10baseT." Transmission rates vary between 10-100 Mbps.. Fiber-Optic Cable. Fiber-optic cable consists of a thin cylinder of glass surrounded by glass cladding‚ encased in protective outer sheath. Fiber-optic

Define the following terms: 1. Horizontal Cable : A type of inside cable designed for horizontal use in non-plenum areas. While horizontal cable must be fire retardant‚ the National Electrical Code (NEC) specifications are not as demanding as those governing the use of plenum cable or riser cable. See also NEC‚ plenum‚ plenum cable‚ and riser cable. 2. Backbone Cable : Backbone cabling is the inter-building and intra-building cable connections in structured cabling between entrance facilities

CHAPTER TWO NETWORKING SYSTEMS AND LOCAL AREA NETWORKS (LAN) A network is a system of two or more computers that are connected in some manner. Each computer on the network has access to the files and peripheral equipment (such as printers or modems) on all the other computers on the network. The origin of local area networks can be traced‚ in part‚ to IBM terminal equipment introduced in 1974. At that time‚ IBM introduced a series of terminal devices designed for use in transaction-processing
