The diagram of heredity represents hereditary ties between classes. For example, at the picture below the structure of heredity and Filled Rectangle class behavior is shown.
Diagrams of protocols define arguments of classes for protocols call. At the picture below the diagram of a protocol for Fill-closed-object is shown.
It is obvious from the diagram that Fill-closed-object gets requests from Polygon object (primary argument) and Color object (secondary argument) and returns the request to Polygon object.
Diagrams of objects creation come into diagrams of types and describe possible situations at composition of ties between created objects..
The diagram of methods systematization describes specific type of system behavior at the influence on the set of methods. Arrows on the diagram point at additional influences, done at the sets of methods. The sets of methods are grouped accordingly to additional obligatory conditions. At the example given below the set of methods ‘Print’ has an obligatory condition that the object must be printed and the set of methods ‘Print-Text’ – that the printed object must be a text.
Diagrams of clients represent clients and operations suppliers. Double arrows on the diagram point from the called operation to the calling operation. At the example given below a diagram of clients is shown. On this diagram the Redisplay operation which belongs to Redisplayable-object class calls the Erase operation of the Erasable-object class and the Draw operation of the Drawable-object class.
IDEF4 standard implies not only graphical presentation but the additional information about diagrams of heredity, methods systematization and types which are contained in specifications. Accordingly to IDEF4 standard there are specifications of invariant classes and specifications of obligatory conditions.
Specifications of invariant classes are connected with diagrams of heredity and define influences which form properties of each concrete class of objects. For each class there exists a separate specification. For instance, the properties “Each square has four sides” and “All square sides are equal” are the properties of specification of the Square class.
Specifications of obligatory conditions are connected with sets of methods in diagrams of methods systematization and define obligatory conditions, which influence on methods and which methods should satisfy.
For each set of methods there is one specification of obligatory conditions. For example the set of methods ‘Pop’, which deletes values from the stack, as obligatory condition will have the absence of attempts to delete the value from the stack if the stack is empty.
IDEF 4 standard is developed by professional planners and programmers of the U.S. Air Force Armstrong Laboratory and is intended to facilitate the usage of object-oriented technologies at software development.

When describing any computer network, we imagine a set of devices and nodes, arranged in some way. Talking about network structures, we should distinguish physical and logical network topologies, as physical topology is about devices location and logical topology illustrates data flow. In the same time, they do not have to match, and some devices, such as repeaters, may have a physical star layout, but a bus logical topology.
There are two main types of computer network topologies: Physical topology that show the physical organization of a network - equipment and types of connections. Star network topology involves a set of devices that is connected to a single hub (router). Ring network topology means that, devices connected according this topology have two connections, connecting with nearby devices to make a loop. Bus network topology is the topology presented at the current diagram. It is similar to a ring topology. The difference is that data moves up and down a linear connection, copying itself where network equipment works as bus-stations along the way. This network topology can be used for small network, or when adding an extra device into a network.

Local area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements.
The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.

Nodes of any computer network are somehow organized in a hierarchy or a layout. Some of the common layouts like star network topology are more reliable and some like ring topology withstand high loads better. It is also important to distinguish logical topologies from physical.
This diagram represents a typical view of the star network topology. The star network topology is one of the most frequently used network topologies in the majority of office and home networks. It is very popular because of its low cost and the easy maintenance. The plus of the star network topology is that if one computer on the local network is downed, this means that only the failed computer can not send or receive data. The other part of the network works normally. The minus of using star network topology is that all computers are connected to a single point-switch, or hub. Thus, if this equipment goes down, the whole local network comes down.
