"A computer network diagram is a schematic depicting the nodes and connections amongst nodes in a computer network or, more generally, any telecommunications network. 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."

"The Global Positioning System (GPS) is a space-based satellite navigation system that provides location and time information in all weather conditions, anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. The system provides critical capabilities to military, civil and commercial users around the world. It is maintained by the United States government and is freely accessible to anyone with a GPS receiver." [Global Positioning System. Wikipedia]

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.

Diagram of a Basic Computer Network. Computer Network Diagram Example
What is a computer network? This is a set of devices and systems that are connected to each other (logically or physically) and communicate with each other. This could include servers, computers, phones, routers, and so on. The size of this network can reach the size of the Internet, and can consist of only two devices connected by a cable.This sample shows the connection scheme of the home WLAN equipment to the Internet.
The vector stencils library "Cisco WAN" contains 15 symbols of wide area network (WAN) devices and equipment: CSU/ DSU (Channel Service Unit/ Data Service Unit), WAN, MUX (multiplexer), PBX switch, Hub, NAT (network address translation), distributed and local directors, PBX (private branch exchange), Network clouds, DPT (dynamic packet transport).

"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 private or public network transports. Business and government entities utilize WANs to relay data among employees, clients, buyers, and suppliers from various geographical locations. In essence, this mode of telecommunication allows a business to effectively carry out its daily function regardless of location. The Internet can be considered a WAN as well, and is used by businesses, governments, organizations, and individuals for almost any purpose imaginable.
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."

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)."

How to Customize a Task‘s Duration
When you create an automatically scheduled task, ConceptDraw PROJECT assigns it duration of one day by default. You need modify that duration to reflect the real amount of time that the task requires.HelpDesk
How are Summary Values of Project Phases Calculated
The project schedule usually consists of a list of project tasks joined into project phases. Each task has its own value such as duration, cost, % complete, etc."A telecommunications network is a collection of terminal nodes, links and any intermediate nodes which are connected so as to enable telecommunication between the terminals. The transmission links connect the nodes together. The nodes use circuit switching, message switching or packet switching to pass the signal through the correct links and nodes to reach the correct destination terminal. Each terminal in the network usually has a unique address so messages or connections can be routed to the correct recipients. The collection of addresses in the network is called the address space. Examples of telecommunications networks are: computer networks, Internet, telephone network, global Telex network, aeronautical ACARS network." [Telecommunications network. Wikipedia]

This vehicular network diagram sample was drawn on the base of picture illustrating the post "LED Traffic Signals and Vehicle Lights for Optical Broadband Communications" from the blog "Terranautix".
"Visible Light Communication (VLC) is a rapidly emerging field that focuses on the use of light sources (between 400 THz and 800 THz) for the primary purpose of broadband communications. In order to transmit data over light, the light source (transceiver) is pulsed on and off rapidly to create a data stream, similar to fiber optic communications, but in the wireless form, or “Free-Space Optical Transmission“. By pulsing lights many thousands (and millions) of times per second, data transmission occurs at a rate undetectable by the human eye. Optical receivers convert the light pulses to an electronic signal on the receiver end. The Light Emitting Diode (LED) is the primary form factor currently undergoing extensive research."

"A vehicular ad hoc network (VANET) uses cars as mobile nodes in a MANET to create a mobile network.[1] A VANET turns every participating car into a wireless router or node, allowing cars approximately 100 to 300 metres of each other to connect and, in turn, create a network with a wide range. As cars fall out of the signal range and drop out of the network, other cars can join in, connecting vehicles to one another so that a mobile Internet is created. It is estimated that the first systems that will integrate this technology are police and fire vehicles to communicate with each other for safety purposes. ...
Vehicular ad hocal networks are expected to implement wireless technologies such as dedicated short-range communications (DSRC) which is a type of Wi-Fi. Other candidate wireless technologies are cellular, satellite, and WiMAX. Vehicular ad hoc networks can be viewed as component of the intelligent transportation systems (ITS).
As promoted in ITS, vehicles communicate with each other via inter-vehicle communication (IVC) as well as with roadside base stations via roadside-to-vehicle communication (RVC)." [Vehicular ad hoc network. Wikipedia]
