Fundamental principles of technology

A technology is a combination of components or parts that come together to achieve a purpose. The laser printer uses a computer-controlled laser to "write" images on the copier's drum. Then the particles of the toner stick to the drum and then melt on the paper.

A technology consists of building blocks that are in turn technologies, and this is repeated until reaching the elementary components.

All technology takes advantage or exploits some effect or phenomenon
If you examine a technology you will always find that it uses a phenomenon. Alcohol distillation is based on the phenomenon that alcohol evaporates at a lower temperature than water. The hammer depends on the phenomenon of impulse transmission from a moving object (the hammer) to a static object (the nail).

Technologies can be very simple or very complicated. When the primitive man took a rock and used it to open a coconut, he was using simple technology. Keeping the international space station running requires much more complex technologies.

what it is for and cloud security

Another advantage is the persistence of the data, which is much safer in this regard. The cloud platforms are specially designed for fault resistance, saving duplicates for example if there is a problem on a hard disk. Following the example of Quipu, it is much safer not to lose the invoices if they are in the cloud, since we will use a professionalized system for that purpose, not if they are on an external hard drive of ours, which may eventually fail, or if they are in a filing cabinet, which we can easily lose or can be damaged for any reason. Drawbacks? The cloud also has some drawbacks. An obvious one is the (relative) loss of control over our data, since we delegate them to someone other than us. We do not have the photos in a device at your fingertips, but to a place on the Internet of which we do not know their physical location. Even so, it is a loss of relative control: the provider of any cloud service is the first interested in the perfect operation of its service; In

8 questions and answers about self-managed wireless networks

After several years of research and approach to the subject, Fidel Alejandro Rodríguez, professor of the Faculty of Communication of the University of Havana,  Blade Servers Engineer   invites us to reflect on the debate based on the new regulations for the use of Private Data Networks and the use of High Speed ​​Wireless Systems ... Then Cubahora completely reproduces a post that will be published this Friday on its Facebook profile. 1. Why do we need community networks? -Because they help create solutions for the lives of small communities without waiting for them to come from above. -Because they contribute to shorten the access gap to goods, services and knowledge related to the exchange of information. -Because they connect us with the closest ones and allow us to attend to more specific information flows. - Because they do not require commercial profitability for the circulation of information. 2. What can we achieve in a community network? -Manage the collective pr

What is managed cloud?

In the managed cloud, the client forgets all of the above and lets expert companies take care of the administration and carry out tasks such as architecture implementation, operation, monitoring and reporting, as well as performing performance adjustments, make backups and implement a disaster recovery plan. In this cloud model, if the client finds a problem, just pick up the phone and an expert will be attending to the situation immediately, if it is not that the solution is already implemented before the client speaks with a representative. To put it in other words, in the conventional cloud the client only rents a space, while in the managed cloud he hires a space and a team of experts that provide maintenance and manage it according to his needs. The differentiator between the two clouds is that whoever rents the managed cloud has the assurance that it has support staff available 24 hours a day, 7 days a week without the need for an internal IT department, which allows you to dele
