     1.7 -Types of electronic communication can be divided in synchron and asynchron communication. Syncron communication are direct dialogs with little delay. Telephone conversation is an example. Asynchron communication are one-way message systems. Dialogs are possible as well, but not in the same direct fashion. These two groups can also be split by the time needed for data delivery. Synchron communication requires nearly real-time delivery, whereas message delivery times of several seconds or even minutes are sufficent for asynchron communication.
     1.8 +Types of electronic communication can be divided in synchron and asynchron communication. Syncron communication is direct dialog with little delay. Telephone conversation is an example. Asynchron communication consists of independent messages. Dialogs are possible as well, but not in the same direct fashion. These two groups can also be split by the time needed for data delivery. Synchron communication requires nearly real-time delivery, whereas for asynchron communication message delivery times of several seconds or even minutes are sufficent.

    1.10  Another possible separation is to distinguished written and recorded information. Recorded information, like audio or video data, is accessable only in a linear way by spooling and replay. Written information, on the other hand, can be accessed in arbitary sequence, detail and speed.

    1.13 +Lenke and Schmitz \cite{lenke95} use the same criteria to classify \emph{new media}. %fixme: is this term common?
    1.14 +They additionally divide into local and remote communication---the latter is presumed here---and by the number of communication participants. As communication technologies for n:m communication (like chatrooms) are usable for 1:1 too (private chat), and ones for 1:1 (email) are usable for n:m (mailing lists), a classification by participant structures is ommited here.

    1.16 -Figure \ref{fig:comm-classification} shows a classification of communication technologies sorted by these two criteria. Email and \NAME{SMS} are written and asynchron communication; \NAME{IM} and chats are written information too, but synchron. Recorded information are voicemail and video messages as examples for asynchron communication. VoIP is an example for synchron communication.
    1.17 +Figure \ref{fig:comm-classification} shows a classification of communication technologies sorted by the properties synchron/asynchron and written/recorded.

    1.18  
    1.19  One might be surprised to find Instant \emph{Messaging} not in the group of \emph{message} communication. Instant Messaging could be put in both groups because it allows asynchron communication additional to being a chat system. The reasons why it is sorted to dialog communication are its primary use for dialog communication and the very fast---instant---delivery time.
