What are technological systems?
Technological systems
consists of the various
physical parts of a
technology. In addition, a
technological system also
includes the network of
political, social, and
economic relationships
and forces that control and
shape the technology.
Technological systems
used for communication
have: inputs, processes,
and outputs dealing with
storage and
transmission

a given repertoire with
something in order to
facilitate the transmission
of data (generally
numbers or text)
through telecommunicatio
n networks or for data
storage.

What is machine to machine
communication?
• Machine to machine
communication refers
to technologies that
allow both wireless
and wired systems to
communicate with
other devices of the
same ability.
A financial transfer occurs when a bank in San Diego automatically pays for an
ATM transaction from a store in Tampa. The funds are credited to the store's

How do you transmit a message?
• In order to transmit a
message, a sender in one
system starts the channel so
that it can send messages to
the other system. The
sender requests the receiver
at the other end of the
channel to start. The sender
sends messages from its
transmission queue to the
receiver. The receiver puts
the messages on the
destination queue.
The process of placing a message on a channel so that it can be sent to
the receiver is called:
