VPN is full meaning, ‘Virtual private network’ (Virtual private network) When multiple computers (or separate networks) are brought under the same network through a public network, they are called VPN. It serves as a way to secure communication and encrypt data. We usually use VPNs to protect our privacy online.
There are several types of VPNs available to Internet users. And each VPNE offers security and opportunities from different angles. VPN gula is divided into different categories according to their protocol and usage. So if you have an idea about all types of VPN, it will be helpful to find the one you need.
PPTP: PPTP is a very common point-to-point tunnelling and has been used since Windows 95. PPTP is very easy to set up but due to its age, it is easy to find vulnerabilities and can be attacked by hackers.
SSTP: The full form of SSTP is a secure socket tunnelling protocol. Which supports Microsoft’s protocol and Windows. It uses SSL v3 and can bypass the firewall. SSTP is considered to be more secure and effective than PPTP.
L2TP / IPsec: Layer 2 Tunnel Protocol does not actually offer any encryption. This is considered effective encryption but all traffic is encrypted from L2TP and then added to the top resulting in slower operation than other options.
Open VPN: Open VPN is used in open search technology such as: SSL, V3 / TLS v1 protocol and OpenSSL encryption library. Open VPN is highly configurable and one of the safest options on the web.
IKEv2: Internet Key Exchange version 2 also called IKEv2. It was created in 1997 through a partnership with Microsoft Cisco. Which uses the X.509 certificate in the pairing protocol for authentication.
VPN is used for three main reasons:
1. Privacy (So the main function and purpose of VPN is to protect your privacy online
2. unblocking (The second purpose of using VPN is to unblock! You may know that there is some content that can only be viewed or used in certain countries (such as PayPal)! So you can unblock that blocked content through VPN!
So if your purpose is only unblocking then there are some good VPNs for you: Turbo VPN, Super VPN, VPN Master, Hola VPN, Secure VPN, Droid VPN etc! And if your purpose is privacy, then these normal VPNs are not for you! This will ruin your privacy! So some good VPNs for you are: HMA VPN, Cyber Ghost VPN, Unseen Online, VPN Hub etc!
And if you are a Cyber Expert or hacker, then the purpose of using your VPN is privacy + secure! Without these two, a hacker is never safe! In this case, if you use the first-line VPN, you will be caught unawares! So some good VPNs for you are Express VPN, Nord VPN, Whoer VPN, Hide.me VPN etc!
So let’s say we need to buy a VPN, or free VPN is enough ??? The answer is very simple if your purpose is unblocking and privacy then free VPNs are enough but free VPN is not at all safe to have privacy + secure! You can be trace at any time, which a hacker would never want! So you must buy a VPN! And now almost all VPN sites can be paid with Bitcoin, Ethereum, Paypal, which almost all of us have!
So far today. Forgive the mistake.
Nowadays people are confused about one thing when they thinking about to buy a new camera. Is DSLR camera is better over Mirrorless or not!
Well in this article i’m going to explain whether you should get a mirrorless camera or a DSLR. And which one is good for videography and vlogging. Also going to clear up some myths about mirrorless cameras.
SLR is stand for single lens reflex, back in the film days it was SLR when you come out with digital cameras you put a D in front of it you get digital SLR. Now what’s going on inside of that cameras that you have a mirror box, you have a pentaprism which is how you get your optical viewfinder when you take a picture the mirror flips out of the way blocking the viewfinder letting light go through and exposing the sensor or the film and that is how an SLR works.
There is no mirror in mirrorless camera, thats why they call it mirrorless camera.
Probably you already have a mirrorless camera in your pocket or on your desk or somewhere right now!
Maybe you’re even holding it because you’re using a cell phone. Every cell phone camera is a mirrorless camera. Now you have cameras that act similarly to DSLRs except they don’t have mirrors in them they started to change the technologies and evolved how photography is being done today.
Sony, Nikon, Canon, Fuji, Olympus I think most of them there are a lot of different cameras out there that have moved into the mirrorless world and now more than ever before the lines are starting to blur between DSLRs and mirrorless cameras.
DSLRs tend to be larger thicker and heavier, they take up more space because they have to have that mirror box and the pentaprism inside.
On the other side, mirrorless cameras tend to be thinner smaller and lighter. Mirrorless camera has more updated technology than the DSLR. In the same budget range, you’ll have a lot more focus points in mirrorless one.
One feature that I like in mirrorless camera is silent shooting. That means you can take pictures without any shutter sounds, like smartphones. As the mirrorless camera doesn’t have any shutter so it can provide shutter sound free shooting feature. Maybe you’ll need this feature in some situation. But using DSLR there is no way to take pictures silently without that shutter sound.
And one thing that I don’t like about the mirrorless camera is it has less battery life than DSLR. Even though if u take some extra battery with you, this is not a problem. But sometimes you may need longer single battery life, especially while recording video.
