Essential Applications for our Windows Computer

A new computer use to have few number of applications installed by default. Only Operating System and a set basic applications not really useful. In this page we would like to recommend an additional set of useful applications we think are mandatory in a computer. We consider only Microsoft Windows operating system ones. Continue reading

Basics of Internet

Internet is not a network but a set of them. This set of networks provide connection between computers and equipments at a global level. Nowadays mostly all used networks are connected to internet or use the same technology. Why internet is the biggest and the only public network in the world? The simplest answer is all network technologies were designed to be small. Internet was born big and it was designed to be big. Of course some technology advances have been needed but no other network technology has become as big as internet. Once become a standard no other network technology can compete with Internet.

Welcome to Technology Issues site. Our purpose in this web pages is to explain some concepts and words we find everywhere in a simple and clear way. This pages don’t intend to be the most complete and detailed but explaining and give examples allowing us to have a clear and basic idea about them. 

We hope they are useful. If you have any comment, question or suggestion don’t hesitate to contact us through our e-mail address info@technology-issues.com. You can also visit our Technology Issues blog.

mobile-networksMobile Networks are continuously improving speed even competing with fix networks and covering more areas. In the opposite, with the same capacity, are more expensive tan fix ones. Thanks to flat fees they have reach a huge development around the world.


Fixed Networks  are the ones connecting our home, our office or university. In few years we have evolved from modems through telephone line to ADSL and optic fiber connection in our home. It is true fix networks provide the highest capacity but they are not available everywhere. Mostly the high-capacity connections are only available in big cities.

are the ones giving sense to all the rest. Internet or Networks have no sense without Internet Explorer, Skype or WhatsApp. Actually we use applications and applications use our devices and communication networks. We include four chapters with our recommendations for mobile devices and windows computers,  education environment and enterprise environment as well.


Internet is not a network but a lot of them connected. Internet is a set of networks allowing computers and equipment connection at a global level. Nowadays all networks (connected to internet or not) are using internet technology. Why internet has become the biggest and unique public network in the world? The reason could be most of network technologies created in the past were created to be small. Internet was born big and it was designed to be huge.

The huge development of communication networks, both fixed and mobile, have allowed development of new applications not executed in our computer but executed anywhere in internet. This kind of applications are involved in a new concept called “Cloud Computing” or processing in the cloud (internet). Most of the times it is not known where this application is executed but obviously there is a physical computer underneath.

Electricity NetworkElectricity Network is the base for our technology world. They distribute necessary energy for electronic equipments in our homes, data processing centers, industry and even remote places where mobile network antennas are installed. Additionally fiber optics are deployed together with electricity cables in towers and pipelines. These fiber optics are used by operators for mid and long distance connections. Currently electricity networks are in a kind of revolution with “SmartGrid” technology deployment.
