Wide area network (WAN) topology. Computer and Network Examples

A Wide area network (WAN) is a telecommunication network that is used for connecting computers and covers a wide geographical area. WANs often contain a few smaller networks (LANs, MANs, etc.). The packet switching and circuit switching technologies are effectively used in WANs.
This example was created in ConceptDraw DIAGRAM using the Computer and Networks Area of ConceptDraw Solution Park and shows the Wide area network topology.
The vector stencils library "Cisco LAN" contains 23 symbols of local area network (LAN) devices and equipment for drawing Cisco LAN topology diagrams.
"Network topology describes the layout of interconnections between devices and network segments. At the Data Link Layer and Physical Layer, a wide variety of LAN topologies have been used, including ring, bus, mesh and star, but the most common LAN topology in use today is switched Ethernet. At the higher layers, the Internet Protocol (TCP/ IP) has become the standard, replacing NetBEUI, IPX/ SPX, AppleTalk and others.
Simple LANs generally consist of one or more switches. A switch can be connected to a router, cable modem, or ADSL modem for Internet access. Complex LANs are characterized by their use of redundant links with switches using the spanning tree protocol to prevent loops, their ability to manage differing traffic types via quality of service (QoS), and to segregate traffic with VLANs. A LAN can include a wide variety of network devices such as switches, firewalls, routers, load balancers, and sensors.
LANs can maintain connections with other LANs via leased lines, leased services, or the Internet using virtual private network technologies. Depending on how the connections are established and secured in a LAN, and the distance involved, a LAN may also be classified as a metropolitan area network (MAN) or a wide area network (WAN)."

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.

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.
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.
The vector stencils library "Cisco WAN" contains 15 symbols of wide area network (WAN) devices and equipment for drawing Cisco WAN diagrams.
"A wide area network (WAN) is a network that covers a broad area (i.e., any telecommunications network that links across metropolitan, regional, or national boundaries) using leased telecommunication lines. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. ...
Related terms for other types of networks are personal area networks (PANs), local area networks (LANs), campus area networks (CANs), or metropolitan area networks (MANs) which are usually limited to a room, building, campus or specific metropolitan area (e.g., a city) respectively.
... it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different LANs, MANs and other localised computer networking architectures. ...
WANs are often built using leased lines. At each end of the leased line, a router connects the LAN on one side with a second router within the LAN on the other. Leased lines can be very expensive. Instead of using leased lines, WANs can also be built using less costly circuit switching or packet switching methods. Network protocols including TCP/ IP deliver transport and addressing functions. Protocols including Packet over SONET/ SDH, MPLS, ATM and Frame relay are often used by service providers to deliver the links that are used in WANs." [Wide area network. Wikipedia]

"The ideal telecommunication network has the following characteristics: broadband, multi-media, multi-point, multi-rate and economical implementation for a diversity of services (multi-services). The Broadband Integrated Services Digital Network (B-ISDN) intended to provide these characteristics. Asynchronous Transfer Mode (ATM) was promoted as a target technology for meeting these requirements" [Broadband networks. Wikipedia]
"Wireless broadband is technology that provides high-speed wireless Internet access or computer networking access over a wide area. ...
Wireless networks can feature data rates roughly equivalent to some wired networks, such as that of asymmetric digital subscriber line (ADSL) or a cable modem. Wireless networks can also be symmetrical, meaning the same rate in both directions (downstream and upstream), which is most commonly associated with fixed wireless networks. A fixed wireless network link is a stationary terrestrial wireless connection, which can support higher data rates for the same power as mobile or satellite systems.
Few wireless Internet service providers (WISPs) provide download speeds of over 100 Mbit/ s; most broadband wireless access (BWA) services are estimated to have a range of 50 km (31 mi) from a tower. Technologies used include LMDS and MMDS, as well as heavy use of the ISM bands and one particular access technology was standardized by IEEE 802.16, with products known as WiMAX."
