 Identify characteristics of Ethernet networks  Identify straight-through, crossover, and rollover cables  Describe the function, advantages, and disadvantages of repeaters, hubs, bridges, switches, and wireless network components  Describe the function of peer-to-peer networks  Describe the function, advantages, and disadvantages of client-server networks  Describe and differentiate between serial, ISDN, DSL, and cable modem WAN connections  Identify router serial ports, cables, and connectors  Identify and describe the placement of equipment used in various WAN configurations

LAN Physical Layer Symbols

Ethernet Connector Requirements

Connection Media

UTP Implementation

Note: Only 4 wires being used to T and R

Patch Panels are used for Organization in Wiring Closets. Sometimes referred to as punch downs.

Hubs (multi-port repeaters or concentrators)

  • Passive
    • serves as a physical connection point only
    • does not manipulate or view the traffic
    • does not boost or clean the signal
    • does not need electrical power
  • Active
    • must be plugged into an electrical outlet
    • Amplifies the signal before it is sent to the other ports
  • Intelligent
    • sometimes called smart hubs
    • function like active hubs with microprocessor chips and diagnostic capabilities making them more useful for troubleshooting situations.
    • more expensive than active hubs

Bridges

  • Break up LAN

Segments

  • Limit Traffic
  • Filter based on the

Destination MAC

Switches

  • switches are popular connectivity solutions because they improve network speed, bandwidth, and performance.
  • All switching equipment perform two basic operations: - switch data frames - maintenance of switching operations where switches build and maintain switching tables and search for loops
  • operate at much higher speeds than bridges
  • support new functionality, such as virtual LANs

Peer-to-Peer Networks

  • All Peers are equal
  • 10 Host max (recommended)
  • Advantages
    • Easy to create
    • Each user can manage their own resources
    • No need for anything to be centralized
    • No need to for centralized management

Client/Server Environment

  • network services are located on a

dedicated computer called a server

WAN Serial Connections

  • Signal Clocking (Clockrate) determined by:
    • Data Communications Equipment (DCE)
    • Channel/Data Service Unit (CSU/DSU)

Routers and Serial Connectors

DSL and Cable

  • DSL
    • Standard telephone lines
    • RJ-
  • Cable
    • Coax
    • F connector

Console Connections

  • Used to manage a device, such as switch

or router, locally

  • Uses a DB-9 to RJ45 adapter
  • Uses Rollover cable
