Local area network (LAN). Computer and Network Examples

A local area network (LAN) is a devices network that connect with each other in the scope of a home, school, laboratory, or office. Usually, a LAN comprise computers and peripheral devices linked to a local domain server. All network appliances can use a shared printers or disk storage. A local area network serve for many hundreds of users. Typically, LAN includes many wires and cables that demand a previously designed network diagram. They are used by IT professionals to visually document the LANs physical structure and arrangement.

Personal area (PAN) networks. Computer and Network Examples

A Personal area network (PAN) is a computer network that is used for data transmission between different personal devices (computers, telephones, digital devices, etc.) and for connecting to the higher level network and Internet. PANs can be wired with computer buses (USB and FireWire). A wireless personal area network (WPAN) can be made using the network technologies such as Bluetooth, IrDa, UWB, Z-Wave, ZigBee, Body Area Network. A personal area network handles the interconnection of IT devices at the surrounding of a single user. Generally, PAN contains from following such appliances: cordless mice and keyboards, cordless phone, Bluetooth handsets.
This example was created in ConceptDraw PRO using the Computer and Networks Area of ConceptDraw Solution Park and shows the Personal area network.

ERD Symbols and Meanings

Crow's foot notation is used in Barker's Notation, Structured Systems Analysis and Design Method (SSADM) and information engineering. Crow's foot diagrams represent entities as boxes, and relationships as lines between the boxes. Different shapes at the ends of these lines represent the cardinality of the relationship.
The Chen's ERD notation is still used and is considered to present a more detailed way of representing entities and relationships.
To create an ERD, software engineers mainly turn to dedicated drawing software, which contain the full notation resources for their specific database design - ERD symbols and meanings. CS Odessa has released an all-inclusive Entity-Relationship Diagram (ERD) solution for their powerful drawing program, ConceptDraw PRO.

Cisco Routers. Cisco icons, shapes, stencils and symbols

Network infrastructure planning is a very important process in the network construction, and the share of time allocated to this within the scope of the entire project may reach 60-80%. A competent and thorough approach to planning contributes to the quick investment return, and also increases the reliability and flexibility of the final system, reducing the probability of additional costs related to the incorrect implementation.
Any planning begins with an analysis of the business requirements to the final system. Basic network parameters, which should be assessed are the scalability, accessibility, cost, speed and safety.
Speed and cost are often mistaken for the most important parameters, and the rest of the parameters aren't even remembered. This is not entirely correct. Initially, it is necessary to assess the business plans for the future, because sometimes it is more profitable to invest more money in the beginning. If the business is to develop, then, consequently, demands on

Entity Relationship Diagram Examples

Creating an entity-relationship (ER) model is to visually represent the structure of a business database, where data equates to entities (or objects) that are linked by defined relationships expressing dependencies and requirements. By nature it is an abstract visualization, the first step in the design process towards creating a logical and functional database.
ConceptDraw gives the ability to describe a database using the Entity-Relationship model. Entity-Relationship Diagram solution includes icons advocated by Chen's and Crow’s Foot notation that can be used when describing a database.

Hybrid Network Topology

This sample was created in ConceptDraw PRO diagramming and vector drawing software using the Computer and Networks solution from Computer and Networks area of ConceptDraw Solution Park.
This is example of the Hybrid network topology.
Network topology is the topological structure of the computer network. There are many types of the network topologies: bus, star, ring, mesh topology, but the most popular is the hybrid topology.
