What is a VPN? How VPNs work?

Often we hear about VPNs and the benefits they may contain for web browsing and today we’ll go deeper into the subject to explain all the details of the virtual private network which helps to establish a connection to other computers in a safe way.

What is a VPN and what does it do?

The first thing we need to understand is the real concept of virtual private network, which is basically a secure network of private browsing that allows computers and devices to connect through an extension of the Internet, without being actually linked to the network, allowing secure transmission of data.

To get a clearer picture, let’s imagine two remote offices that require transmitting data or information and for this it is necessary to connect the computers to a VPN network through an extension of the Internet, that is, through the internet but without involving third parties since it is not a public network.

This connection can be given by remote access, wired connection, through something called Tunneling (Tunnel by SSH) or by internal network (LAN). Because of that, below we explain a little of what each connection means:

Purchase Guide for Second Hand Components

When renovating our PC many of us have had to choose, in certain occasions, to buy second hand components, a market that can serve us as a scape valve when we don´t have enough budget to face the cost of a renovation with new components or we simply don’t want to make that investment because we’re only looking to extend a little the useful life of the device until we can change it completely.

However, the market for second hand components is an authentic jungle, and not only because of the prices, but also because we take the chance of acquiring a product that is in bad condition or that doesn’t work properly, so we must proceed very carefully.

Obviously this doesn’t change the fact that it is an interesting market in which we can find very attractive solutions and at a good price that can be very helpful, but as we said we have to proceed carefully, search exhaustively and mostly, have a clear approximate value that is fair to pay for what we are searching for.

Crucial finally announces their first SSDs M.2 NVMe

It was already unusual for a manufacturer with the category and history of Crucial (which is actually a Micron Technology brand) not to have last generation solid state devices in its catalog, but fortunately that is over as it just announced its new generation of high-performance SSDs with M.2 format and which use the NVMe protocol, using a PCI-Express interface.

Crucial-Ballistix-TX3

You know that since long time ago the SSDs with SATA 3 interface reached their performance limit, which is why manufacturers of storage devices had to look for other alternatives to further improve and they found in the PCI-Express lanes the ideal solution, thanks to their high bandwidth (they use a PCI-Express rail of 32 Gb/s). Of course it was difficult to use this interface with the usual format of 2.5 inches, so the M.2/U.2 format is now the chosen one thanks to the small space it occupies and to its versatility (with M.2 SSDs variants and an adapter which connects directly to a PCI-Express x4 of the motherboard).

Asus transformer 3 aims against Samsung and Huawei in windows 10 tablets.

Transformer 3 is a similar equipment to Transformer Pro 3, but with differences that make it s more economic and not so “premium” as is attempted with the Pro model. It uses the most traditional format of a tablet with windows 10 and less of a hybrid, but maintains elements such as a magnetic connected keyboard that turns it into a laptop.

This tablet has a metallic design and 6.9mm thickness, with a weight of 695 grams. It lacks of a kickstand and hinge that keeps in a vision angle while writing. For this function it has a case and a keyboard sold aside by Asus. Actually, this tablet is more similar to the Samsung Galaxy TabPro than to any other model of its competitors.

MSI GT83S, portable gaming with NVIDIA Pascal SLI GPUs.

This MSI GT8S continues with the concept that the company brought with the monstrous GT80, which means a laptop with big size and thickness superior to most models, where MSI takes advantage to integrate a system of two graphic cards working in SLI and even a mechanical keyboard.

MSI GT83S

The GT83S has a 18.4 inches screen with Full HD resolution, in this matter there are not improvements and it turns out curious that an equipments that could run 4k games easily, keeps limited with 1920 x 1080 resolution pixels. If it was difficult enough to have screens with 17.3” in 4K resolution, to have 18,4” panels, it is very likely that with that resolution it will be even more complicated because of the few models that integrate that diagonal.

The VPN is safe, but not infallible

Lately VPN has been in the spotlight. On one side, as a measure to protect itself upon attempts of espionage: are encrypted tunnels (in most cases) that keep someone from knowing what we are looking on Internet if, for example, we connect to public WiFi networks or we do not trust our ISP.

Unfortunately, and as usually happens in computing, they are not infallible. We have a sample in the failure we’ve seen this week that affected Firefox and Chrome, and that revealed the real IP of the user through RTC. And it’s not the only one.
