What is anonymity?
In real life, anonymity is like walking down the street without anyone recognizing you. However, in the online world, anonymity typically refers to the inability of browsers, ISPs, device software, and others to trace your personal data over the internet. When you use or browse websites or services, they don't know who exactly is using them, only that someone is. This is often achieved by hiding your IP address and encrypting your data in transit.
What is a proxy?
A proxy refers to a computer device that acts as an intermediary or bridge between your device and the internet. When a device uses a proxy to connect to the internet, it changes the source IP address. However, proxies themselves do not provide encryption; scientific accelerators combine proxies with encryption technology. This is one of the differences between VPN tools and scientific accelerators.
What is P2P?
P2P, or Peer-to-Peer, is a network similar to BitTorrent. It allows computers or devices to share files with each other without relying on a central source for downloading files.
What is BitTorrent?
BitTorrent, often abbreviated as BT, refers to the downloading of files through the BitTorrent protocol. If a service supports BitTorrent, it means users can download content through this protocol using a scientific accelerator. Otherwise, it may block or limit BitTorrent downloads.
What is DNS hijacking?
DNS hijacking involves taking control of the DNS (Domain Name System) server through various means to manipulate the resolution of domain names. It leads to the redirection of users to fake websites or the blocking of specific websites, with the intent to steal data or disrupt normal services. DNS hijacking is achieved by altering the DNS server's data to provide incorrect query results.
Symptoms of DNS hijacking include users being redirected to ISP-sponsored pages when trying to access any website, or instances where accessing a well-known domain like Google leads to a different website.
What is DNS pollution?
DNS pollution, also known as DNS cache poisoning, is a method that prevents regular users from communicating with a target host due to receiving false IP addresses. It is a type of attack that manipulates DNS queries, often taking advantage of the lack of authentication and the unreliable nature of UDP-based DNS queries. It involves providing users with fake DNS results for a particular domain, leading them to incorrect IP addresses.
DNS pollution occurs when users access an address, and servers (other than DNS) in certain regions detect the access to a marked address. These servers then pretend to be DNS servers and return erroneous results to users.
What is DNS leakage?
DNS leakage occurs when the DNS, which should be protected by a scientific accelerator, is exposed, revealing the user's IP address. The level of DNS protection varies depending on the quality of the accelerator or VPN tool used. Scientific accelerators usually offer better DNS protection compared to ordinary VPN tools.
What is data transmission encryption?
Data transmission encryption refers to the encryption of both upstream and downstream data when accessing websites or services over the internet. It ensures that the content of your data, both when uploading and downloading, is protected from being read by entities such as web providers, ISPs, or router administrators. However, the level of protection depends on the quality of the accelerator or VPN tool used.
What is an IP address?
An IP address is a unique numerical address (e.g., 196.56.3.45) assigned by your ISP (Internet Service Provider) each time you connect to the internet. A scientific accelerator can mask your real IP address, making it difficult for websites or service providers to track your online activities and actual location.
What is a Kill Switch?
A Kill Switch, also referred to as an Emergency Disconnect, is a feature that functions similarly to a circuit breaker or fuse. Its purpose is to prevent IP and DNS leaks. When using a scientific accelerator and you are connected to a website, such as Google, if the connection is unexpectedly interrupted for any reason, the Kill Switch feature activates an emergency disconnect. This prevents the website from obtaining your IP and location information.
What is a no-logs policy?
A no-logs policy means that the service provider does not keep any records or logs of your online activities. It encompasses three main types of logs:
1. User information logs: Information about users, including usernames, passwords, email addresses, payment details, purchase history, remaining subscription time, home address, and residence country.
2. Connection logs: Records of all incoming and outgoing connections to the server, typically including incoming and outgoing IP addresses, timestamps, and data transferred during the session.
3. Usage logs: Information about a user's internet usage, such as visited websites, downloaded files, software and protocols used, etc.
A no-logs policy ensures that no information about your online activities is stored by the service provider.
What is OpenVPN?
OpenVPN is an open-source software protocol used by many VPN services, including ExpressVPN, NordVPN, SurfsharkVPN, and others. It offers certain advantages in terms of security and is often preferred in regions with strict internet censorship, such as China.
What is a protocol?
A protocol refers to a set of instructions or coding rules used for secure communication in scientific accelerators. Different protocols have significant differences in terms of security, speed, and effectiveness in bypassing censorship. Common protocols include AES, PPTP, L2TP, OpenVPN, IKEv2, WireGuard, and others. Some scientific accelerators introduce their own custom protocols, such as Nord's NordLynx and Express's Lightway, which are built on top of existing protocols.
What is a tunnel?
A tunnel is a term used to describe an encrypted connection between a computer and a scientific accelerator's server. It protects your data and privacy and is considered a secure path for internet access. Some accelerators offer split tunneling services, where a user's connection is split into multiple directions. However, this feature is not available in regions with strict firewall rules, such as China (as in the case of NordVPN).
