WHAT'S DIFFERENT BETWEEN HTTP AND HTTPS ?

By Indian Developers Club
🔰WHAT'S DIFFERENT BETWEEN HTTP AND HTTPS❔❔🔰
HTTP is unsecured while HTTPS is secured. HTTP sends data over port 80 while HTTPS uses port 443. HTTP operates at application layer,
while HTTPS operates at transport layer. No SSL certificates are required for HTTP, with HTTPS it is required that you have an SSL certificate and it is signed by a CA.
HOW HTTP CONNECTION IS ESTABLISHED❔❔

Opening a connection in HTTP means initiating a connection in the underlying transport layer, usually this is TCP. With TCP the default port, for an HTTP server on a computer, is port 80. Other ports can also be used, like 8000 or 8080.

WHAT 443 PORT IS USED FOR❔❔

Port 80 and 443 are ports generally associated with "the Internet". Port 443/HTTPS is the HTTP protocol over TLS/SSL. Port 80/HTTP is the World Wide Web. Let's face it, port 80/443 are generally a given for being open on any type of filtering device allowing traffic outbound on your network.

Note:- Http is not that trustworthy so don't do any online transaction with http website always trust Https website url.
In thr current time there is fake websites of all big companies available on internet.
Sometimes you can't differentiate between fake and original at that time protocol is one of the method to check it's authenticity because all big companies have Https website.

If you like this article please do share with your friends and family members and Help them from scammers.

Difference between Artificial intelligence and Machine learning???

By Indian Developers Club
WHAT IS THE DIFFERENCE BETWEEN ARTIFICIAL INTELLIGENCE AND MACHINE LEARNING❓❓🤔 🧿Artificial intelligence (AI), the ability of a digital computer or computer-controlled robot to perform tasks commonly associated with intelligent beings. The term is frequently applied to the project of developing systems endowed with the intellectual processes characteristic of humans, such as the ability to reason, discover meaning, generalize, or learn from past experience. Since the development of the digital computer in the 1940s, it has been demonstrated that computers can be programmed to carry out very complex tasks—as, for example, discovering proofs for mathematical theorems or playing chess—with great proficiency. Still, despite continuing advances in computer processing speed and memory capacity, there are as yet no programs that can match human flexibility over wider domains or in tasks requiring much everyday knowledge. On the other hand, some programs have attained the performa...

Quantum computers:-Need , Working and Advantages

By Indian Developers Club
 Quantum computers:- In simple terms ( IBM quantum computer) Three Factors Of Quantum Computing:- 1. The Need? Integrated circuit (IC) chips are becoming small and small every year. Nowadays, Transistors are of size of 14 nm and that is smaller than the size of red blood cells. As things get small the regular rule of general  physics doesn't apply. At atomic level quantum physics work. 2. Difference? Ordinary computers use bits to represent data and carry out processes. Bits are like switches ; they can be either 1 or 0, just like "ON" or "OFF". Just like bits, quantum computers have "qubits". Which are basic unit of Quantum information. 3. Working? Classic state- Quantum state Instead of 1 and 0, quantum computers use electron spins. The spins can be in the state of positive (1) or negative (0) or both! This is called superposition. Quantum computers use superposition principles; they can ha...
