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

The vector stencils library "Computer peripheral devices" contains 18 clipart images of computer peripheral devices and equipment for drawing network diagrams.
"A peripheral is a device that is connected to a host computer, but not an integral part of it. It expands the host's capabilities but does not form part of the core computer architecture. It is often, but not always, partially or completely dependent on the host.
There are three different types of peripherals:
(1) Input, used to interact with, or send data to the computer (mouse, keyboards, etc.).
(2) Output, which provides output to the user from the computer (monitors, printers, etc.).
(3) Storage, which stores data processed by the computer (hard drives, flash drives, etc.)" [Peripheral. Wikipedia]
The clip art example "Computer peripheral devices - Vector stencils library" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Computer and Networks solution from the Computer and Networks area of ConceptDraw Solution Park.

For documenting the Cloud Computing Architecture with a goal to facilitate the communication between stakeholders are successfully used the Cloud Computing Architecture diagrams. It is convenient and easy to draw various Cloud Computing Architecture diagrams in ConceptDraw DIAGRAM software with help of tools of the Cloud Computing Diagrams Solution from the Computer and Networks Area of ConceptDraw Solution Park.
This pinout diagram example showing a VGA connector (as viewed from the socket) was redesigned from the Wikimedia Commons file: DE15 Connector Pinout.svg. [commons.wikimedia.org/ wiki/ File:DE15_ Connector_ Pinout.svg]
"A Video Graphics Array (VGA) connector is a three-row 15-pin DE-15 connector. The 15-pin VGA connector is found on many video cards, computer monitors, and high definition television sets. On laptop computers or other small devices, a mini-VGA port is sometimes used in place of the full-sized VGA connector.
DE-15 is also conventionally called RGB connector, D-sub 15, mini sub D15, mini D15, DB-15, HDB-15, HD-15 or HD15 (High Density, to distinguish it from the older and less flexible DE-9 connector used on some older VGA cards, which has the same shell size but only two rows of pins).
VGA connectors and cables carry analog component RGBHV (red, green, blue, horizontal sync, vertical sync) video signals, and VESA Display Data Channel (VESA DDC) data. In the original version of DE-15 pinout, one pin was keyed by plugging the female connector hole; this prevented non-VGA 15 pin cables from being plugged into a VGA socket. Four pins carried Monitor ID bits which were rarely used; VESA DDC redefined some of these pins and replaced the key pin with +5 V DC power supply.
The VGA interface is not engineered to be hotpluggable (so that the user can connect or disconnect the output device while the host is running), although in practice this can be done and usually does not cause damage to the hardware or other problems. However, nothing in the design ensures that the ground pins make a connection first and break last, so hotplugging may introduce surges in signal lines which may or may not be adequately protected against. Also, depending on the hardware and software, detecting a monitor being connected might not work properly in all cases." [VGA connector. Wikipedia]
The pinout diagram example "VGA connector pinout" was created using the ConceptDraw PRO diagramming and vector drawing software extended with the Audio and Video Connectors solution from the Engineering area of ConceptDraw Solution Park.
