Electrical Symbols — Transmission Paths
Data transmission, digital transmission or digital communications is the physical transfer of data (a digital bit stream or a digitized analog signal) over a point-to-point or point-to-multipoint communication channel. Examples of such channels are copper wires, optical fibers, wireless communication channels, storage media and computer buses. The data are represented as an electromagnetic signal, such as an electrical voltage, radiowave, microwave, or infrared signal.

In communications and electronic engineering, a transmission line is a specialized cable or other structure designed to carry alternating current of radio frequency, that is, currents with a frequency high enough that their wave nature must be taken into account. Transmission lines are used for purposes such as connecting radio transmitters and receivers with their antennas, distributing cable television signals, trunklines routing calls between telephone switching centres, computer network connections and high speed computer data buses.

Working as a designer, you might find developing projects exciting and difficult at the same time. It is a challenging task to create a usable interior design that will fulfill all the customer’s requirements. So, in order to aid yourself, you can use special software to create site plans, landscape designs, furniture layouts.
This example of an interior plan introduces an internal area of a small cafe. The floor plan demonstrates interior angle "view from above". It involves many different elements of furniture such as tables , chairs and various cushioned furniture. Also it includes a kitchen fixtures and furniture. Making this plan was managed by the ConceptDraw Cafe and Restaurant Floor Plan solution. The libraries, composing this solution contain about vector graphic 300 objects. It can be use to help interior designers to develop interior design proposals, communicate ideas and concepts that relate to a interior design.

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

Local area network connects computers and other network appliances within an area, such as office building or a campus. It can be difficult to provide such network without a predesigned plan. For these purposes you can use network diagram software, which helps you to create LAN network diagrams and office network diagrams quickly and effortless. This will speed up your work and you can save the diagram for the future network improvements.
The following diagram illustrates a network topology of the small office. LAN configuration has a star topology. The local network joins 8 computers among which are several desktop PCs, laptop, two iMacs and iBook. The end-point devices are divided into three groups. Each group is connected to its hub. There is a network printer and a modem, which are interconnected with other devices through a network server. Each computer on the LAN can access the server through a corresponding hub.

When designing a network, it is important to take into account the hierarchy of network devices. When you have a root device you should consider a tree network topology that might have any number of lower levels as you might need. This technology is based on star and bus network topologies.
This is a schematic representation of a Tree computer network topology. A tree topology means that some star networks are linked together. A star network is a topology of the local network where a central workstation is connected with each end-user computer or peripherals. A tree structure means that, the central nodes of these star networks are linked to a main cable (the Bus topology). So, a Tree network topology is a few Star networks connected into a Bus topology. This scheme can be applied to draw the particular physical or logical network diagrams using the ConceptDraw Computer and Networks solution.
