Formally Defined Terms

Observer
An observer is an object that processes information from another object.
Transfer
A transfer is a process in which information contained in an observer changes to include information contained in another object.
Communication
Communication is the transfer of information from an object to an observer.
Channel
A channel is an observer that transfers information from an object and then transfers that information to another observer.
Transmitter
A transmitter is an object that transfers information to a channel.
Receiver
A receiver is an observer whose information is changed by information transferred from a channel.
System
A system is an object that contains other objects
Sub System
A sub system is a system contained by a system
Communication System
A communication system is a system which contains a transmitter, a channel, and a receiver.
Serial Communication System
Serial Communication System contains one transmitter and one receiver.
Parallel Communication System
Transmit
Transmitting is the transfer of information from an object to a channel.
Receive
Receiving is the transferring of information from a channel to an observer.
Input
Input is information that is received.
Input is the process of receiving information.
Output
Output is information that is transmitted
Output is the process of transmitting information
Storage
Storage is a communication system that is a sub system of another communication system.
Store
Storing is the process of a channel transmitting information to storage.
Retrieve
Retrieving is the process of storage transmitting information to a channel.
Delay
A delay is the process of a channel storing and retrieving information.
Complexity
Complexity is the sum of all the delays in all of the channels of a communication system.
Processor
A processor is an object that changes information.
Information Processor
An information processor is a system that inputs, processes, stores, and outputs information.
Input Subsystem
An input subsystem is a subsystem of an information processor that receives information
Output Subsystem
An output subsystem is a subsystem of an information processor that transmits information
Processor Subsystem
A processor subsystem is a subsystem of an information processor that changes information
Storage Subsystem
A storage subsystem is a subsystem of an information processor that stores information.
Primary Storage
Primary Storage is a subsystem of an information processors storage subsystem whose information is available with very little delay.
Secondary Storage
Secondary Storage is an information processor which is a subsystem of the storage subsystem of another information processing system whose information is available after more of a delay than for the primary storage subsystem.
Data
Data is information that has been changed so it can be processed by a data processing system.
Code
A Code is information that changes how a data processor processes data
Data Processor
A data processor is an information processor that encodes information into data, processes the data, and then decodes the data into information.
Decode
Decoding is the process of changing data into information.
Encode
Encoding is the process of changing information into data.
Decoder
A decoder is the output subsystem of a data processor.
Encoder
An encoder is the input subsystem of a data processor.
Encryption/Encrypt/Encipher
Encryption is the process of encoding information so that it can only be processed by a specific data processing system.
Decryption/Decrypt/Decipher
Decryption is the process of decoding data so that it can be processed by a specific information processing system.
Crypt/Cipher
A cipher is encrypted information.
Memory
Memory is the storage subsystem of a data processor.

Analog Computer
An analog computer processes analog signals.
Sample
Sampling is the process of only recording the events received on one channel while a particular recurrent event is received on another channel.
A sample is a list of events recorded by sampling.
Quantization
Quantization is the process of recording only events whose information matches information based on a rule or algorithm
