Network Diagram Examples

"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. For example, if a network appliance is intended to be connected through the Internet to many end-user mobile devices, only a single such device may be depicted for the purposes of showing the general relationship between the appliance and any such device."

The physical LAN and WAN diagram template for the ConceptDraw PRO diagramming and vector drawing software is included in the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

"A local area network (LAN) is a computer network that interconnects computers in a limited area such as a home, school, computer laboratory, or office building using network media. The defining characteristics of LANs, in contrast to wide area networks (WANs), include their smaller geographic area, and non-inclusion of leased telecommunication lines. Ethernet over twisted pair cabling, and Wi-Fi are the two most common technology standards currently used to build LANs." [Local 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."

The vector stencils library "Rack diagrams" contains 55 hardware symbols for creating the server rack layout diagrams using the ConceptDraw PRO diagramming and vector drawing software.
"A 19-inch rack is a standardized frame or enclosure for mounting multiple equipment modules. Each module has a front panel that is 19 inches wide, including edges or ears that protrude on each side which allow the module to be fastened to the rack frame with screws. Equipment designed to be placed in a rack is typically described as rack-mount, rack-mount instrument, a rack mounted system, a rack mount chassis, subrack, rack mountable, or occasionally simply shelf. The industry standard rack cabinet is 42U tall." [19-inch rack. Wikipedia]
"A rack unit, U or RU is a unit of measure that describes the height of equipment designed to mount in a 19-inch rack or a 23-inch rack. The size of a piece of rack-mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.
A typical full size rack is 42U, which means it holds just over 6 feet of equipment, and a typical "half-height" rack would be 18-22U, or around 3 feet high." [Rack unit. Wikipedia]
