FAQ

What is a virtual machine?

A virtual machine (VM) is a software program that emulates the hardware of a computer. It allows you to run multiple operating systems (OS) on a single physical machine, each in its own isolated environment.

A virtual machine consists of a virtual processor, memory, storage, and network interfaces, and is configured and managed using a hypervisor, which is a software program that manages the virtual machine. The hypervisor provides each virtual machine with its own virtualized hardware resources, such as CPU, memory, and storage, and manages the communication between the virtual machine and the physical hardware.

Virtual machines are useful for a variety of purposes, including testing and development, running legacy applications, and hosting multiple websites or applications on a single server. They allow you to run different operating systems and applications on the same physical machine, which can be more cost-effective and efficient than using multiple physical machines.

In summary, a virtual machine is a software program that emulates the hardware of a computer and allows you to run multiple operating systems on a single physical machine. It is managed using a hypervisor and is useful for a variety of purposes, including testing and development, running legacy applications, and hosting multiple websites or applications on a single server.

How to Extract Data From Any Site Without Coding?

What are rotating residential proxies?

Rotating residential proxies are a type of residential proxy network that automatically switches the IP address used by the proxy server. The IP address is changed periodically, typically every few minutes or hours, in order to provide a higher level of anonymity and avoid detection by websites.

Rotating residential proxies are often used for web scraping, data extraction, and other online activities that require a high level of privacy and security. By changing the IP address regularly, rotating residential proxies can help to prevent websites from detecting and blocking the proxy server, improving the reliability and efficiency of web scraping and other online activities.

Rotating residential proxies can also help to improve the quality of data extracted from websites. By using a new IP address for each request, rotating residential proxies can reduce the risk of websites blocking requests or blocking access to the site altogether, providing a more comprehensive and accurate view of the data being extracted.

However, it is important to choose a reputable and reliable provider of rotating residential proxies, as some providers may offer low-quality or unreliable IP addresses that can lead to poor performance and increased risk of detection. Before choosing a service, be sure to research the provider, read reviews from other users, and test the service to ensure that it meets your needs.

Proxies vs VPN: which is better?

The choice between a proxy and a VPN depends on your specific needs and use case.

Proxies are usually faster and more efficient, but they don’t offer the same level of encryption and privacy as a VPN. Proxies are good for bypassing geo-restrictions and accessing blocked websites, but they don’t hide your IP address from the websites you visit.

On the other hand, VPNs encrypt all internet traffic and hide your IP address, providing a high level of privacy and security. VPNs are good for protecting your privacy and security online, but they can be slower than proxies due to the encryption process.

In conclusion, if you want to bypass geo-restrictions and access blocked websites, a proxy might be the better choice. If you’re concerned about privacy and security, a VPN might be a better option.
