Lecture Basic network management: Chapter 4 - Trung tâm Athena Chapter 4: LAN TERMINOLOGY and COMPONENTS ATHENA Objective LAN Terminology LAN transmission media LAN technology and topology LAN networking devices ATHENA LAN Terminology ATHENA LAN Terminology LAN Transmission Media • What types of transmission should be used to connect LAN components? LAN Topology • What will be the shape or topology, that defines the LAN? ATHENA Transmission Media Transmission media refers to the type of cable or wireless system that is used to connect network devices: • Coaxial Cable • Twisted Pair – Unshielded twistedpair – Shielded twistedpair • Fiber Optic Cable ATHENA Transmission Media ATHENA Coaxial Cable Coaxial cable consists of central copper wire surrounded by two layer of protective shielding Inexpensive, light, flexible and easy to work More resistance to Electromagnetic Interference (EMI) and attenuation ATHENA Coaxial Cable (2) Attenuation: loss of signal strength along wire ATHENA Coaxial Cable (3) ATHENA Types of Coaxial Cable The two basic classifications for coaxial cable are as follows: • Thinnet • Thicknet ATHENA Thinnet Thinnet is a flexible cabling medium that is inexpensive and easy to install Thinnet is approximately 0.25 inches (0.5cm) Thinnet can transmit a signal for 185 meters (610 feet) ATHENA Thicknet Thicknet coaxial cable is approximately 0.5 inches (1.3cm) Thicknet can transmit approximately 500 meters (1650 feet) Copper core thicker than Thinnet core ATHENA Thicknet (2) ATHENA Connection Hardware The most common is the British Naval Connector (BNC): • BNC cable connector • BNC Tconnector • BNC barrel connector • BNC terminator ATHENA Connection Hardware (2) BNC cable connector ATHENA Connection Hardware (3) BNC Tconnector: connects the network interface card in the PC to the network cable ATHENA Connection Hardware (4) BNC barrel connector: connects two thinnet cable segments into longer segment ATHENA Connection Hardware (5) BNC terminator: closes end cable to stop signal ATHENA Twisted Pair Twoinsulated strands of copper wire twisted around each other There are 2 categories of twisted pair: • Shielded twisted pair (STP) • Unshielded twisted pair (UTP) ATHENA Twisted Pair STP UTP ATHENA
