left lacking the full range of cognition
derived facilities to separate fact from illusion. We are bereft the capability
to establish an adequate trust infrastructure on which to establish a
comprehensive policy infrastructure through which to engage in the necessary
interactions to, in fact, obtain the sustenance demanded by our appetites.
When we speak
about the projection of the existence of sustenance, in general we are speaking
of the availability of information about sustenance; information that, in some
cases, comprises sustenance and in others merely points the way. This concept
of information is grounded in the cognitive realization of the sensori-motor
experience; memories and understanding if you will. The Web comprises an
interaction medium through which this information is conveyed from producer to
consumer. While the Internet provided for the interconnection of diverse
networks first among governments, companies and other entities around the
world, these networks merely provided the fabric for the interconnection and
interaction of diverse producers and consumers of information. It required the
emergence of a common sensori-motor experience across these networks to truly
enable an interaction environment that began to merge with the human social ecosystems
through which the needs hierarchy is addressed.
The detection
and acquisition of information proceeds through interactions that can be
modeled with the approaches we discussed in Chapter 3. Specifically, the Open
Systems Interconnection reference model describes for us the basic protocol
stack necessary to allow two dissimilar entities to interact. The ubiquitous
access to information through the Internet derives from a convergence in the standardization of two distinct layers within
this generic stack. First, in an effort to enable the basic exchange of
information, the early development of electronic mail facilities within the
context of the original Arpanet incarnation of the Internet stimulated the
creation of a family of specifications for representing information to be
conveyed. This evoked the development of a series of standards addressing the
presentation layer of the general protocol stack. This is the layer where
presentation formats are defined. A family picture has a different format than,
say, a legal document. However, the actual conveyance of information required
the standardization of the next lower protocol level; that of the session
layer. Whether I send a family picture or legal document, I can use the same
means to get them to the desired addressee. Once a standard way of conveying
content is established, I can send all sorts of content besides just family
pictures or legal documents. For example, I can send out my Christmas Cards.
Electronic mail
evolved according to the paradigm of state provided postal services such as is
elaborated as a prerogative of the federal government within the United States
Constitution. The concept involves the conveyance of messages across time and
space and allows for the pursuance of an extended interaction with another
entity across both domains. I write a letter to John. I place it in an envelope
on which I write John’s address. I put a stamp on the envelope to pay for the
conveyance and I enter it into the postal system by dropping it in a mailbox.
The postal system then conveys the letter to the destination specified by the
address on the envelope where it is then delivered by a person. To receive
mail, all one must do is place a qualified mailbox at a standard address, which
can be essentially anywhere. Within the United States, the postal service is required by law
to deliver mail appropriately addressed and funded with a stamp.
To establish an
electronic analog to the postal system, two specifications were developed for
use in tandem to transfer messages from the original sender to the final
receiver. These were the Simple Mail Transport Protocol (SMTP) and the Post
Office Protocol (POP). The first is used to convey messages from the sender to
a persistent server that provides a continuously available mail drop for the
receiver, while the second is used to allow the receiver to retrieve messages
