Typing * (the asterisk) sends a signal to the CPU, but its effect depends entirely on the context: in a search engine, it's often a wildcard for "anything" (like *.com); in programming, it means multiplication or pointers; in file systems, it's a wildcard for file matching; and in a text editor, it usually appears as a character or can trigger special formatting like bolding (like *bold* becoming bold).
Thus, when you type a domain name like "google.com" on your web browser, it checks its cache for the most recent copy of the DNS record for that domain. If there is a recent copy of the DNS record for that domain, the browser uses the IP address in the cache to send a request to the server.
We stopped having to type it because nowadays, the www.example.com and example.com URLs both refer to the same server (URL is like a set of coordinates on a map that is given to your web browser to go and find the web site). Some sites don't, and so typing either form might yield different results.
The moment type https://www.google.com in your browser and press enter, your browser sends a request to a Domain Name System(DNS) server, requesting the IP address associated with the domain name www.google.com . The DNS server then searches its records and returns the corresponding IP address to your browser.
Here's what happens in more detail: The browser sends a request to the server using IP to establish a connection. The server receives the request and sends back a message acknowledging the request to establish a connection. This is the handshake process.
Third-party tracking companies can track you across most websites you visit. Third-party tracking lets advertisers show you targeted ads based on your interests and online activity. For example, if you visit a website about running and fitness, you might see ads for running shoes when you visit other websites.
Valid characters allowed in URLs are:
However, when they went to register their domain name, they accidentally misspelt “googol” as “Google.” Despite the typo, Page and Brin decided to stick with the new name. Little did they know that this serendipitous error would become one of the most recognisable brands in the world.
No, people can't see that you've Googled them. Alphabet Inc., the company behind Google Search, doesn't have any business interest in letting people know when they've been searched. Although it may well keep records like this for its own reasons, it doesn't share this information with individuals.
The only difference between the two protocols is that HTTPS uses TLS (SSL) to encrypt normal HTTP requests and responses, and to digitally sign those requests and responses. As a result, HTTPS is far more secure than HTTP. A website that uses HTTP has http:// in its URL, while a website that uses HTTPS has https://.
Modern websites often omit WWW in URLs because it's not required for functionality, but HTTP or HTTPS is essential for website security and performance. HTTPS is the secure version of HTTP, encrypting data to protect users.
Mind blown: Saying “World Wide Web” is actually quicker than saying “WWW”! Who knew the abbreviation would take longer than the full phrase?
So, while this parameter may look suspicious, it's completely safe and nothing to be concerned about. gws_rd=ssl means Google web server, redirect, SSL (Secure Sockets Layer). “gws_rd” is an abbreviation for Google web server, redirect. It indicates that Google uses a web server to process and route a search query.
CNN.com name servers are specified when the domain is registered with the registrar. The request is then sent to to the CNN.com name servers which will look up http://www.cnn.com in their zone files and reply with the request. There is a forward lookup and a reverse lookup zone file.
Google Safe Browsing protects over 400 crore devices and, when enabled in Chrome, displays warning messages letting you know that the site you are trying to enter might be unsafe. These warnings help protect you and your personal information from potential malware and phishing scams.
Is it possible to know how many times my name has been googled? No, it is impossible to know the exact number of times your name has been googled, as search engines do not release this information.
Why doesn't Generation Z use Google? Google is (and looks set to remain for quite some time) the largest online search portal. However, Generation Z prefers visual and interactive platforms to solve doubts or find inspiration.

Percent-encoding is a mechanism to encode 8-bit characters that have specific meaning in the context of URLs. It is sometimes called URL encoding. The encoding consists of a substitution: A '%' followed by the hexadecimal representation of the ASCII value of the replaced character.
%5B and %5D are the URL-encoded forms of [ and ] , respectively. ASCII code for [ is 91; hexadecimal representation is 5B. ASCII code for ] is 93; hexadecimal representation is 5D.
