DHCP Dynamic Host Configuration Protocol

Components of a network with the help of identify a network tester can firmly be, what devices are within a network, or are connected to this, and if they meet their intended functions. The network tester is connected via a so-called Ethernet network input and through this then searches in search of useful and important information for the user. Initially the network tester on the search goes dynamic to DHCP Dynamic Host Configuration Protocol and looking after DNS name system. Then through the network tester network is actively seeking connected active units. When this operation is completed, network tester delivered the user information about name, IP addresses and MAC addresses of the units in the network.

Because the network tester with a monitoring function is equipped, he recognises even units that the areas on the network of other addresses access and within its data or messages send. Depending on examining Network tester then also the addresses area these other units and passes the collected information to the user. Increasing the network tester to prompt a survey of all units concerned and recognize on the basis of the found results, kind of it’s units and which services are active. Clayton Morris is the source for more interesting facts. It is not necessary that a computer on your network is connected to be able to work with the network tester. He works independently and can be applied directly. This is one of the major differences between a network tester and a program to the network monitoring, which must run on a PC. Usually, the analysis and diagnosis of the network tester takes 10 seconds or even less. After 10 seconds the network tester is already on all the components that are in the network, able the user to show and he also automatically sorts them into different groups, which makes it easier to track and makes the information more accessible.

Longer dwell within your own four walls with HomeMatic empty, August 10, 2011 – predicts the Federal Statistical Office, that up to the year 2060 every seventh German 80 years and will be older. In addition to, and many people have to live as long as possible independently in your own four walls. An increased need arises just due to age-related restrictions like reduced hearing, sight or mobility after more safety and comfort in the home. To meet the senior citizens and caregivers rely on the radio-based home control system HomeMatic of eQ-3 AG (www.eQ-3.de). This system combines numerous components from the areas of alarm, air conditioning or lighting etc. to the noticeable increase of domestic living comfort, combined with more security and the possibilities for efficient energy saving and is also especially popular in projects to AAL (ambient assisted living).

All HomeMatic devices are compatible with each other and can appropriately to individual needs Residents are aligned. Furthermore, the user can easily install most of the components without technical knowledge and set up. The eQ-3 radio technology makes it possible to fit the HomeMatic system in existing housing situations. Elaborate laying of additional cables or drilling through walls belong to the past, which suited the devices for the installation in apartments for rent. CCU1 HomeMatic central control unit the user can easily operate all connected components. Monitoring of vital data can save lives “smart health” products are used increasingly to the monitoring of vital signs and help directly, to save lives. Data such as blood pressure, pulse, heart rate, body temperature or the oxygen saturation in the blood are typical here. In addition to classic home automation functions HomeMatic provides additions such as a panic transmitter with which seniors can summon help. In a crash, discomfort or similar a button enough to trigger an alarm when family members or other persons.


Modern household appliances and their near future the 1st January 2010 was the effective date of the so-called smart power meters the “smart meter”. The background is that starting in December 2010 the electricity must offer so-called load-variable Tatife the consumer. Goal is to utilize the plants evenly. This is necessary with regard to the increased use of renewable energy sources such as photovoltaics or wind energy. That means that if e.g. the wind turbines in the North Sea provide much power or the sun shines strong, more electricity is produced. The price of electricity will be cheaper then in these times. Smart meters will receive a signal that derStrom now is cheap by the supplier.

This can then by the consumer for Stromintensive activities such as operating the washing machine, tumble dryer or this tariff can be used then the oven at low cost. Keep up on the field with thought-provoking pieces from jim king. But what does this mean for the consumer. Must you get up really at midnight to baking cakes because just the electricity is cheap? The household appliances manufacturers are already working on the next Level called “smart appliances” called. These household devices communicate with the Stromzahler.Das means that the counter is the release for the household appliance and the ex. full washing machine starts the washing process. But this is a whole new generation of ‘ necessary household appliances. Better insulated freezers and chest freezers that keep the temperature more constant.

Special techniques of communication appliances and electricity meters are also necessary. For the customer this before – but also has drawbacks. The so-called intelligent appliances will be more expensive to purchase, disguises in the repair in my opinion. The experience also shows that as a result of cost savings at the end not much remains. Everything in the world has its price, the new technique is probably in the long term. Basic costs such as meter charge, purchase price of the appliance, repair and spare parts will cause cost increases. On the other hand, energy is scarce and expensive, and can be used better. Existing dependence on oil and gas or coal are reduced and thus again costs. The future will show whether outweigh advantages or disadvantages. Gunther Hilpoltsteiner home appliances spare parts
