Modern-Day Multimedia Communications

• E-mail, Instant messaging, Blogs, and
• Wireless Communication

22
The Internet

• E-mail
• Predates the internet, was crucial in developing
  the internet
• Started in 1965 to aid communication between
  users of a time-sharing mainframe computer
• Ray Tomlinson of ARPANET first to put _at_ between
  name and machine in 1971
• Today, 91 of internet users between 18 and 64
  use e-mail

23

• Instant Messaging Services
• Began in 1970s using UNIX and other multi-user
  operating systems
• Graphical User Interface (GUI) based messaging
  services (ICQ, AIM) developed in late 1990s
• Originally a text-only form of communication like
  email, IM services now include
• Video conferencing
• Voice Over Internet Protocols
• Web conferencing

24

• Blogs
• An abbreviation of web log, they are online
  diaries
• Began sometime in 1994 the actual word blog
  wasnt coined until 1999
• Predominantly text based, blogs today may also
  include photos, sketches, audio files/podcasts,
  videos, and hyperlinks
• Today, blogs have stretched beyond diary form,
  and they can be found discussing everything from
  politics to newspaper comics
• Blogs are being seen more and more as important
  sources of news not covered by mainstream media
• Hurricane Katrina
• CBS Rathergate

25
Wireless Communication

• Developed as an offshoot of radio, wireless
  systems today use radio waves to transmit info
• Two main forms of wireless communication today
  Bluetooth and Wi-Fi

26

• Bluetooth
• Became popular by enabling communication between
  cell phones and hands-free headsets
• Low power consumption
• Range of 10100 meters
• Can be used with a wide range of devices cell
  phones, laptops, printers, digital cameras, PCs,
  video game consoles

27

• Wi-Fi
• greater power consumption than Bluetooth in
  exchange for a stronger connection
• Need to be near a hotspot, or access point to
  use Wi-Fi enabled devices
• Wi-Fi devices must be configured to transmit
  files and share resources and audio links
• Faster connection than bluetooth, hotspots have
  better range, overall Wi-Fi is more secure
• Wi-Fi allows users to connect to the internet and
  each other (through peer-to-peer mode)
