Final answer:
The main difference between HTTP and HTTPS is security; HTTPS is secure as it encrypts data between the browser and the website, while HTTP does not. Trustworthy sources often have .edu, .gov, or .org domains. For more information on internet privacy and security, consult educational resources on the subject.
Step-by-step explanation:
The difference between sites displayed using HTTP and HTTPS is in their security. HTTP stands for HyperText Transfer Protocol, and when used alone, it means the data between your browser and the website is transferred in plain text. This makes it vulnerable to eavesdroppers and attackers. On the other hand, HTTPS stands for HyperText Transfer Protocol Secure, which means that communication between your browser and the website is encrypted. This encryption is obtained through the use of SSL/TLS, which ensures that only the intended recipients can understand the transferred information. Thus, it is HTTPS that indicates a secure website, not HTTP.
When evaluating the trustworthiness of a website, one can also look at the domain. For example, URLs ending in .edu are affiliated with educational institutions, .gov are government websites, .org typically belong to nonprofits, and .com are generally commercial. Of these, .edu, .gov, and .org sites are more reliable sources than .com sites because they represent recognized institutions rather than businesses.
