The Data flow diagram (DFD) example "Payment for goods using UPS code scanner" shows data flow in process of payment for goods in the shop using the MaxiCode scanner.
"MaxiCode is a public domain, machine-readable symbol system originally created and used by United Parcel Service. Suitable for tracking and managing the shipment of packages, it resembles a barcode, but uses dots arranged in a hexagonal grid instead of bars. MaxiCode has been standardised under ISO/ IEC 16023.
A MaxiCode symbol (internally called "Bird's Eye", "Target", "dense code", or "UPS code") appears as a 1 inch square, with a bullseye in the middle, surrounded by a pattern of hexagonal dots. It can store about 93 characters of information, and up to 8 MaxiCode symbols can be chained together to convey more data. The centered symmetrical bullseye is useful in automatic symbol location regardless of orientation, and it allows MaxiCode symbols to be scanned even on a package traveling rapidly." [MaxiCode. Wikipedia]

How to Create a Data Flow Diagram using ConceptDraw PRO

Data flow diagramming is a highly effective technique for showing the flow of information through a system. Data flow diagrams reveal relationships among and between the various components in a program or system. DFD is an important technique for modeling a system’s high-level detail by showing how input data is transformed to output results through a sequence of functional transformations. The set of standard symbols is used to depict how these components interact in a system. ConceptDraw PRO allows you to draw a simple and clear Data Flow Diagram using special libraries.
The vector stencils library "Logical symbols" contains 49 logical symbols for drawing logical network topology diagrams.
"Logical topology, or signal topology, is the arrangement of devices on a computer network and how they communicate with one another. How devices are connected to the network through the actual cables that transmit data, or the physical structure of the network, is called the physical topology. Physical topology defines how the systems are physically connected. It represents the physical layout of the devices on the network. The logical topology defines how the systems communicate across the physical topologies.
Logical topologies are bound to network protocols and describe how data is moved across the network. ... EXAMPLE : twisted pair Ethernet is a logical bus topology in a physical star topology layout. While IBM's token ring is a logical ring topology, it is physically set up in star topology." [Logical topology. Wikipedia]

The vector stencils library "Network layout floorplan" contain 34 symbol icons for drawing computer network floor plans and communication equipment and cabling layouts.
"Networking hardware may also be known as network equipment or computer networking devices. Units which are the last receiver or generate data are called hosts or data terminal equipment.
All these terms refer to devices facilitating the use of a computer network. Specifically, they mediate data in a computer network. ...
Typically, networking hardware includes gateways, routers, network bridges, switches, hubs, and repeaters. But it also includes hybrid network devices such as multilayer switches, protocol converters, bridge routers, proxy servers, firewalls, network address translators, multiplexers, network interface controllers, wireless network interface controllers, modems, ISDN terminal adapters, line drivers, wireless access points, networking cables and other related hardware.
The most common kind of networking hardware today is a copper-based Ethernet adapter because of its standard inclusion on most modern computer systems. Wireless networking has, however, become increasingly popular, especially for portable and handheld devices.
Other hardware prevalent in computer networking includes data center equipment (such as file servers, database servers and storage areas), network services (such as DNS, DHCP, email, etc.) as well as devices which assure content delivery." [Networking hardware. Wikipedia]
