A protocol is a set of common rules and instructions that must be followed. A technical example unless perhaps if you are invited to have tea with the Queen of England, as you would have to follow a certain protocol during a free game. You should know when the arc / courtesy, and how to address (your Madge just not do!), You should know what to mix with spoon and fork to eat with. Moreover, the right way to approach the queen is "Ma'am" rhymes with 'jam', not rhyme with "farm". If the protocol is not followed correctly, you may be asked to leave
When computers communicate with each other, it is the same -. If the rules aren 't follow - everything stops. This set of communication rules is called a protocol. Going back to our tea party, imagine if the other guests consisted of various diplomats from around the world - Japanese Tea protocol can be very different from that used by the Germans, and knowing that it is of use vitally important
[Just as we communicate with each other in different ways, and for how computers communicate with each other - there are many different protocols, such as HTTP (hypertext transfer protocol ), FTP (file transfer Protocol) and SMTP (Simple Mail transfer Protocol). All these different types of protocols have different rules and perform different functions. For example, SSL (Secure Sockets Layer Security protocol) provides a secure connection between Internet browsers and Web servers, allowing you to transmit private data securely online.
What is PPTP?
PPTP (Point-to-Point Tunneling Protocol) is a method of creating a virtual private network (VPN) - like Hide My Ass ! Pro VPN.
One way to look PPTP would be to imagine a highway going from point A to point B. This highway has a lot of trucks up drive plate down, wear things that must be delivered either point or B. has now let's imagine again that we are in a helicopter looking down -. and since these flatbed trucks have no roof, it is easy to see what they carry
PPTP does something a bit special though, as he creates his own "tunnel" to send its trucks down. Our helicopter, we can see there is a new tunnel from A to B, but we have no idea what is going through it, if indeed something goes through it at all. All we know is that there is a connection between two points. The rest is hidden from view.
Similarly, when a user wants to connect securely to their work network from a hotel or Wi-Fi, they do not want others to see that they do and they use a PPTP VPN to create a 'tunnel' for encrypted data.
a VPN is a secure Internet connection between your Internet service provider (ISP) and our Internet provider. When you use a VPN ALL for your online business is "encrypted", so that any attempt to break into your Internet connection to steal private and confidential information will be in vain because your Internet traffic is well hidden behind the VPN.
