Local network area. Computer and Network Examples
A Local Area Network (LAN) is a computer network that interconnects computers on the limited area such as a home, office building, school, bank, computer laboratory, etc.
The LANs connect workstations, computers and devices. It can connect two, three users (home network) or more than thousand users (FDDI network). The users of the LANs can communicate with each other, each computer of the LAN can use the common devices (such as printers, scanners, etc.) and data. LANs can transmit the data on the limited distances fast enough.
Now the most common technologies for building LANs are Ethernet over twisted pair cabling and Wi-Fi. A number of corporations use the Token Ring, FDDI, ARCNET technologies.
ConceptDraw DIAGRAM is a powerful network diagramming and vector drawing software. It provides the Computer and Networks Area with many Solutions that contain the wide set ready-to-use predesigned vector stencils and examples to help you design the LANs quick and easy.

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
