concerning
Communication

Characteristics of Communication
What is Communication?
Informal:
Formal:
Communication is when Alice tells Bob something.
Communication shall be defined as the act of passing information encoded in messages from senders through a channel to recipients.
Science:
Communication Studies or
Information Theory
Not every message contains information:

Fun Fact
What is Information?
Information Theory:
- description of a state
- basic state: bit X = 1 or 0
- measured as entropy H
What is a Channel?
The channel is the medium that allows to convey the message.
Examples:
- over the air (speaking)
- over wire (LAN)
- electro-magnetic waves
(WLAN, Bluetooth, Satellite TV, GPS, GSM/LTE,
smoke signs)
Test.
Channel Characteristics
- simplex, half-duplex, full-duplex
- transmission range
- quality
- costs per unit of information
(the smallest unit of information is the bit 0 or 1) - volume (bits per time)
- speed (meter per time)
- distributed vs centralised (topology)
History of Channels
-
everything is small, costly and very distributed
(horse post, gossiping) -
everything is large and centralised and monoplex (TV, radio), cheap
-
everything is large, duplex (social media), high volume (big data), fast and cheap (fake news) and in High Definition!

Governance Models for Communication
Inspiration: Joel Spolsky on Google Plus (2011)
- Who can discover which recipients? (Directory?)
- What format (encoding) of messages is imposed?
(length limit, text, pictures, links, video) - How is sending and receiving of messages or notifications authorised and controlled?
(per sender/receiver/topic) - Who determines sorting/priority of messages?
How are received messages sorted/prioritised? - Who pays the transmission costs?
| Mailinglist | Facebook Page | ||
|---|---|---|---|
| Directory | none | (hidden) list | |
| Format | free, but rather small mails | free, but rather small mails |
constrained by Facebook |
| Authorisation | none | by list owner | FB users/none |
| Prioritisation | ordered by time | ordered by time | unknown |
| Scalability | 1-to-1 | n-to-n | mostly 1-to-n |
| Archive | distributed | central | ? |
| Authorisation Granularity |
user based | all-in | per page (topic) |
Modern Communication
| State of the Art | |
|---|---|
| Directory | yes, configurable |
| Format | free, but semantic, with search, responsive, etc. |
| Authorisation | yes |
| Prioritisation | transparent, configurable (time, popularity, topic) |
| Scalability | n-to-n |
| Archive | yes, configurable |
| Authorisation Granularity |
per user or user group, per topic, per message (mentions, subscribing to tags, topics, blocking, etc.) |
