CISCO NETWORKING ACADEMY PROGRAM SEMESTER 1/
MODULE 5
Cabling LANs and WANs
Hubs

• multiport repeaters (generally have from two to
  twenty-four ports)
• data arriving over the cables to a hub port is
  electrically repeated on all the other ports
  connected to the same network segment, except for
  the port on which the data was sent

MODULE 5
Cabling LANs and WANs
Switches

• Sometimes described multiport bridges
• Operate at data link layer of OSI reference model
• Switches use gathered information to build
  forwarding tables to determine the destination

Wireless

• Wireless signals are electromagnetic waves that
  travel through the air
• Wireless networks use Radio Frequency (RF),
  laser, infrared (IR), or satellite/microwaves to
  carry signals from one computer to another
  without a permanent cable connection
• Two most common wireless technologies used for
  networking are

• IR - line of sight
• RF - out of sight, two approaches used to
  implement spread spectrum for WLAN transmissions
  are Frequency Hopping Spread Spectrum (FHSS) and
  Direct Sequence Spread Spectrum (DSSS)

Host Connectivity

• Host can connect to network using Network
  Interface Card (NIC)
• NIC is layer-2 device and each NIC carries a
  unique code called MAC address

Peer-to-peer Client-server

• Peer-to-peer
• networked computers act as equal partners, or
  peers
• users control their own resources
• Client-server
• server is a central computer that respond to
  requests from clients for file, print,
  application, and other services

Routers and ISDN BRI Connections

• With ISDN BRI, two types of interfaces may be
  used, BRI S/T and BRI U
• A BRI interface with an integrated NT1 is labeled
  BRI U
• A BRI interface without an integrated NT1 is
  labeled BRI S/T

Routers and DSL Connections

• To connect a router for DSL service, use a phone
  cable with RJ-11 connectors.
• DSL works over standard telephone lines using
  pins 3 and 4 on a standard RJ-11 connector.
