MIS  Exam  3  Study  Guide     Data  Networking  Fundamentals   Strategic  Use  of  Data  Networking     •   More  efficient  and  effective  business  operations   •   Geographical  distance  irrelevant  (globalization)   •   More  timely  and  efficient  access  to  information     •   Enable  a  flexible  and  mobile  workforce   Selecting  a  route  for  a  packet   •   Two  metrics   o   Hop  count  (#  sends)   o   Bandwidth  (Link  Speed)   Packet  Switching   •   Advantages   o   Bandwidth  used  to  full  Potential-­‐Shared  use   o   Not  affected  by  single  points  of  failure  (redirects  signal)-­‐  original  DOD  objective     o   During  a  major  disaster,  the  public  telephone  network  might  become  congested,   but  e-­‐mails  and  texts  can  still  be  sent  via  packet  switching     •   Disadvantages   o   Under  heavy  use  there  can  be  a  delay  (latency)   o   Data  packets  can  get  lost  or  become  corrupted     §   Recovered,  but  slows  transmission  latency   o   Real-­‐time  video  streams,  such  as  streaming  video,  can  lose  frames  when  packets   arrive  out  of  sequence   Identifying  Hosts     •   URL-­‐Name-­‐Descriptive  name   o   Well  suited  for  humans  (“name”)   o   Example:   •   IP  Address-­‐  Unique  number     o   Well  suited  for  machines  (“phone  number”)   o   Example:   Understanding  a  URL     •   Protocol-­‐  Method  used  to  interpret  the  webpage   o   HTTP://-­‐hypertext  transfer  protocol   •   Server-­‐identifies  the  location  of  the  website   o   Domain:  Type  of  organization  (.edu,  .com,  .net)   o   Organization:  responsible  party  (.arizona)   o   Location  of  website  on  server:  “www”  directory   •   Resource:  information  about  the  website   o   Filename:  default.htm  (file  name  in  “www”  directory)   o   Type  of  website:  HTM/HTML-­‐  hypertext  markup  language       Wireless  Communication  in  Business   Wireless  Communication  Methods   •   “Multiplexed  Access”     o   Each  person  is  assigned  a  specific  time  or  frequency  on  which  to  speak   •   “Random  Access”     o   Each  person  simply  talks.  If  they  find  others  talking  when  they  talk,  they  stop,   wait  a  ransom  amount  of  time,  and  start  talking  again.     Wireless  Link  Characteristics   •   Differences  from  wired  link:     o   Decreasing  signal  strength:  radio  signal  attenuates  as  it  propagates  through   matter  (path  loss)   o   Interference  from  other  sources:  unregulated  wireless  network  frequencies   shared  by  other  devices  and  general  noise  sources   o   Multi-­‐path  propagation:  radio  signal  reflects  off  objects  ground,  arriving  at   destination  at  slightly  different  times   •   Makes  communication  much  more  difficult   Wireless  Transmission  Media:  Wireless  transmission  over  unguided  media  refers  to  the   methods  of  carrying  data  through  the  air  using  infrared,  radio,  or  microwave  signals.   Wireless  transmission:  Human  voice  meets  the  criteria  for  wireless  transmission   1.   Unguided  media  (air)   2.   Decreasing  signal  strength  (distance)     3.   Interference  (noise)   4.   Multi-­‐path  (echoes)       Wireless  Technologies   •   Wireless  LAN’s:  802.11,  WiFi   •   Cellular  telephone  networks   o   1G  Analog-­‐low  bandwidth   o   2G  Digital-­‐voice  (ISDN  model)   o   3G-­‐  Web/video/IM/Voice   o   4G  WiFi/WiMax   •   Long-­‐range:  Microwaves,  satellite   o   Good  News:  Have  no  right  of  way  issues   o   Bad  News:  No  physical  barriers  can  exist  between  transmitter  and  receiver   §   Satellite   §   Microwave   The  Business  of  Mobile  Commerce   Semantic  Web:  the  idea  of  having  data  on  the  web  defined  and  linked  in  a  way  that  it  can  be   used  by  machines  not  just  for  display  purposes.  But  for  automation,  integration  and  reuse  of   data  across  carious  applications.     Every  person  in  the  society  in  some  way  more  or  less  participates  in  public  business  process,   which  we  name  as  public  commerce  (P-­‐commerce)   o   P-­‐commerce  service  should  be  able  to  integrate  different  types  of  information   with  geographical  data  and  manage  different  type  of  profiles  related  to   preferences,  security,  privacy,  transaction  management  ect..   mCommerce  Business  Opportunities   o   Mobile  shoppers  are  simultaneously  in  the  physical  world  and  in  the  online   world  at  times   o   They  don’t  want  to  get  home  and  find  out  that  the  product  they  bought  has   terrible  reviews  or  is  30%  cheaper  somewhere  else   o   Disjointed  to  integrated   §   Traditional  –  Mass  media,  analog  methods  to  reach  shoppers   §   Transitional  –  digital  tools  used  in  way,  underleveraging  the  media   §   Transformative  –  Digital  tools  that  leverage  the  capability  of  the  new   media   Location  Based  Commerce   o   Mobile  coupons  give  you  the  opportunity  to  capture  price  sensitive  customers,   and  they  also  allow  you  to  capture  data  for  future  marketing   o   Have  consumers  sign  up  online  or  register  via  email  address,  SMS  or  QR  code  o   receive  offers  to  their  phone   o   Scan  a  barcode  directly  on  the  phone     §   Target  has  cartwheel     Accessibility  and  Human  Computer  Interface  (HCI)  Design   Critical  success  factors  for  good  produce  design     1.   Provide  good  design  models  to  users   2.   Make  things  visible     3.   Provide  appropriate  metaphors  that  leverage  the  user’s  experiences  and

Users  know  what  to  do  instinctively   o   Simple  thing  should  not  need  an  explanation  of  how  to  use  them   Using  Design  Metaphors   •   A  metaphor  is  an  image  or  understanding  of  an  object  or  action,  used  to  describe  the   function  of  another  thing   •   Reduced  cognitive  load  required  to  complete  a  task   •   Should  be  based  on  an  understanding  of  users  cultural,  frame  of  reference   Causality   •   Users  often  assume  that  the  thing  that  happens  right  after  an  action  was  caused  by  the   action  resulting  in  False  causality  (incorrect  relationship)   Human  Factor  design  for  error  prevention   •   Avoidance   o   Use  of  techniques  that  eliminate  invalid  choices   •   Detection   o   Detection  of
