"A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. ...
Depending on whether the diagram is intended for formal or informal use, certain details may be lacking and must be determined from context. ...
At different scales diagrams may represent various levels of network granularity. At the LAN level, individual nodes may represent individual physical devices, such as hubs or file servers, while at the WAN level, individual nodes may represent entire cities. In addition, when the scope of a diagram crosses the common LAN/ MAN/ WAN boundaries, representative hypothetical devices may be depicted instead of showing all actually existing nodes."

The Cisco computer network diagram example "Network organization chart" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Cisco Network Diagrams solution from the Computer and Networks area of ConceptDraw Solution Park.

A five level pyramid model of different types of Information Systems based on the information processing requirement of different levels in the organization. The first level represents transaction processing systems to process basic data. The second level represents office support systems to process information in office. The third level represents management information systems to process information by managers. The fourth level represents decision support systems to process explicit knowledge. The fifth level represents executive information systems to process tacit knowledge.
"A Computer(-Based) Information System is essentially an IS using computer technology to carry out some or all of its planned tasks. The basic components of computer based information system are:
(1) Hardware - these are the devices like the monitor, processor, printer and keyboard, all of which work together to accept, process, show data and information.
(2) Software - are the programs that allow the hardware to process the data.
(3) Databases - are the gathering of associated files or tables containing related data.
(4) Networks - are a connecting system that allows diverse computers to distribute resources.
(5) Procedures - are the commands for combining the components above to process information and produce the preferred output.
The first four components (hardware, software, database and network) make up what is known as the information technology platform. Information technology workers could then use these components to create information systems that watch over safety measures, risk and the management of data. These actions are known as information technology services." [Information systems. Wikipedia]

"At the base of the identity of an organisational is its organizational culture. A culture is comprised of the shared values, customs, traditions, rituals, behaviours and beliefs shared by a social group (national, ethnic, organizational, etc.). Cultures also share languages, or ways of speaking. From a communication perspective, cultures are made and remade through the words we use to describe our world. Culture represents a common set of values (“shared meanings”), shared by members of a population, a organization, a project/ programme purpose unit or a profession (e.g., engineers versus scientists). Culture change with the times but the speed at which the culture of different institutions change varies widely."
