9/20

  1. Client Servers vs. Peer 2 Peer
    1. G,I – client Server
    2. Fileshare – Peer 2 Peer
    3. Cell phone / pda – web services - information
  2. Topologies
  3. Network
    1. Repeaters
      1. No intelligence
      2. Only operating at the physical level
    2. Hubs
      1. Broadcasts to all devices on networks
    3. Switches
      1. Looks at the MAC
      2. More intelligent
      3. Communicates only with MAC device
    4. Bridges
      1. Link two different protocols
      2. Mostly works in the MAC layer
    5. Router
      1. Network layer
      2. Congestions, flow control, condition
      3. Static | dynamic
      4. Routers can communicate to other routers
      5. What is the shortest route
      6. What is the optimal route
  4. Media Access
    1. Polling – how am I going to get access | one server is going to back to see if they have something to send back
      1. Server based or end point based (telephone)
      2. Token based | if the token is free you can communicate | otherwise have to wait to send data    
    2. Collision
      1. CSMA / CD - Ethernet
      2. CSMA / CA - Wi-Fi

Architecture & Standards

H/W S/W N/W

Logical – functionality

The University was bent up on coming up with networking

Network Standards – Why are standards important –

  • effectively communicate
  • Compatibility
  • Manages expectations
  • Flatten
  • Layers
  • Wireless card
    • Send packets

VOIP

Dependent on electricity just like wireless internet

Also you can relate wifi voip as cordless phones. They are just extensions of the land lines.
MIS Week 4 Class 1

What type of media does Progressive use

Media
Fiber
Twisted PairSatellite
Cellular

T1 - Copper
WAN - packet Switching - leads to high error rates

Fiber x-25 protocol - error correction and detection

Cellular vs. wireless

Think of what kind of bandwidth
Think of what kind of modem information needs to go through
400,000 Calls a day


A 3 minute song - 4mb Sample rate 44khz voice 8khz
