Unit 6.1 - Coggle Diagram

- - - - it is either free (if the talking is done computer to computer i.e .
      - both computers have VoIP telephones or use their built in/plugged ir microphones
      - and speakers) or at a local rate to anywhere in the world (when VoIP is used to
      - communicate with a mobile or land line telephone rat-her than another computer).
      - that a webcam can also be
        used so that it becomes a type of video chat.
      - More advantages
        
        much cheaper (no need for special
        
        software and additional hardware items - VoIP uses built-in microphones,
        
        speakers and webcams).
- - - - Use of sound and animation/video effects which are more likely to grab
      - the attention of the audience, and can also make the presentation easier to
      - understand.
      - o It is possible to have interactive/hyperlinks built into the presentation; this
      - means the presentation could access a company's website or even key files
      - stored on the cloud (such as video footage, images, spreadsheets and so on).
      - o Use of transition effects allow a presentation to display facts in a key
      - chronological order.
      - o The presentations can be interactive.
      - o They are more flexible; because of the links to websites and other external systems
      - (e.g. the cloud), the presentation can be tailored to suit a particular audience
  - - - There is a need to have special equipment which can be expensive.
      - o Equipment failure can be a disaster when giving multimedia presentations
      - Wherever the presentation is given there may need to be internel access.
      - More of the disadvantages
        
        There is a danger when using multimedia in presentations that the focus is on
        
        the medium (i.e. the multimedia presentation) rather than the message/facts.
        
        o It is very easy to make a bad presentation with too many animation effects
        
        and too much text or irnages.
- - - - disabled people don't have to go to the venue to see the presentation
      - o it is possible to print it out in Braille for the benefit of blind people
      - o the recipient can read the presentation at any time they want
      - o the recipients have a permanent copy which they can refer to at any time
      - they want.
  - - - the presentation needs to be distributed in some way
      - . there are no special effects (sound, video, animation)
      - o there are printing costs (paper, ink, etc.).
- - - - professionalism (gives a degree of credibility to the company)
      - o brand/company awareness (advertises the company by using the same
      - designs on all products)
      - o legal reasons (it helps if there are any legal actions taken - legitimate
      - documents using the company letterhead is re garded as proof of actual
      - communication)
      - o advertising (the letterhead can contain many useful pieces of information to
      - advertise the company)
      - o helps to make the company stand out (will tend to have more impact than a
      - white sheets of paper with a typed company heading)
      - . can make the company appear larger than it is (this could give a degree of
      - confidence to potential customers).
- - - - Sound/video/animation can be added.
      - o Links to other websites/hyperlinks can be used.
      - o Use of hotspots.
      - o Buttons to navrgate/move around the website leading to more information.
      - o Hit counters to see how many people have visited the website.
      - o Can be seen by a global audience.
      - o Can't be defaced or thrown away.
      - o It is much easier to update a website (and there is no need to do a reprint and
      - then distribute the new version).
  - - - Websites can be hacked into and modified or viruses introduced.
      - o Risk of potential pharming.
      - o It is necessary for the potential customers to have a computer and internet
      - connection.
      - o It isn't as portable as a paper-based system (although with modern
      - smartphones and phablets this is fast becoming untrue).
      - o Possible for customers to go to undesirable websites (either by accident or as
      - a result of the pharming attack) - this can lead to distrust from customers.
      - o There is a need for the company to maintain the website once it is set up -
      - this can be expensive.
      - o Because it is a global system, it is more difficult to target the correct audience
      - using website advertising.
- - - - there is no need to look for an operational public telephone in an emergency
      - o it is possible to conduct business or personal phone calls on the move
      - ¡ it is easier to keep in contact with co-workers at the office no matter where
      - you are.
      - More advantages
        
        They allow text messaging:
        
        o this is quicker and less expensive than making phone calls
        
        o also text messages can be sent at any time of the day even if the recipient's
        
        phone is switched off
        
        o they employ predictive texting where the system completes a word from
        
        the first few letters keyed in e.g. key in 'preci' and the phone completes the
        
        word as 'precious'; predictive texting also allows the system to remember
        
        frequently used words - together they increase typing speed.
