Have you ever wondered how our universe is stitched together? Or how matter behaves at the atomic and subatomic levels? Do you know-how is a quantum computer different from a supercomputer, or what are the functions that it can perform which a typical computer can't?
\nOr, have you ever thought of the amplification of photon particles in a laser beam? Our universe is full of occurrences that are hard to explain. However, the answer to all these questions lies in understanding the fundamentals of nature. For that, let us take a look at Quantum mechanics, which explains the functioning of particles together at the smallest level. Quantum mechanics is a branch of physics which is mainly concerned with the behaviour and nature of matter and energy and atomic and subatomic levels.
\nWith huge advancements in this field, the concept of quantum computers and quantum internet has now come to life. Typical computers are based on binary digits, that is, 0 and 1. Quantum computers, on the other hand, are based on qubits. A qubit or quantum bit is the basic unit for quantum information. They are based on particle's physical properties, such as the spin of an electron, and hence differ in various ways. We know that electron spin can either up or down, but things change when it comes to quantum mechanics. It follows the concept of superposition, according to which an electron can exist in a state in which it has a spin in both directions simultaneously. This may sound strange according to what we observe generally, yet this is how Quantum mechanics work.
\nOpen the hosts file. Click on File > Open and Copy and Paste the following path`
\nc:\\Windows\\System32\\Drivers\\etc\\hosts
You can edit the hosts file
\nSuppose you want to block facebook.com on your system and want to add a custom domain for your website. Just Copy and Paste following Lines
\n0.0.0.0 www.facebook.com\n127.0.0.1 www.customdomain.com
After finishing the Editing, Save your hosts file
\n
Open your browser and try to access www.facebook.com and see you can’t access this site
\n
Use following instructions for Linux
\nIn the Linux terminal window, open hosts file using a favorite text editor
\n$ sudo vim /etc/hosts
Use following instructions for macOS
\n
sudo vim /etc/hosts in the terminal\n-- It will prompt for the password, enter your administrator password\n-- Enter administrator Password\n
Using the vim text editor you can easily edit you. The macOS hosts file is also similar to the windows and Linux hosts file. I am blocking Facebook and adding custom domain here as well.
\n
The hosts file is found on all operating systems. The hosts file is a powerful tool. It can make your computer more secure and safer by blocking malicious sites
