Yes. Just about everything to do with Linux on the command line is case sensitive, including commands and file names.
Check your username and password. Most passwords are case sensitive, so a word like Apple is not the same as apple. If you still cannot sign in, request your login information directly from the website.
AnswerNo, SQL is not defined as case-sensitive in the standards.However, certain implementations of SQL may be case sensitive, in certain scenarios. Notably, MySQL on a Linux or Unix server is most likely case sensitive in regards to table names. Also, some collations (string storage formats) are case sensitive. Finally, column and table names may be case sensitive within a query on some SQL servers (i.e. "select * from USER where user.name = 'test'" might result in an error). When it doubt, check the manuals for the server you are using.
Website names and Email user names are NOT case sensitive, meaning you can write them in lower or upper case, it wouldn't matter. Only passwords are case sensitive. If you meant to ask why they are generally written in lower case when displayed on a website or other medium....they just look better that way.
Yes xml is case sensitive, this includes enumerations which are also case sensitive.

Both. "Case sensitive" means that upper case and lower case characters are treated as different characters.
HTML is not case-sensitive, while C is a case-sensitive language. In HTML, the tags, attributes, and values can be written in uppercase or lowercase letters, and it will still be interpreted the same way by the web browser. For example, the "p" tag can be written as or , and both will be interpreted as paragraph tags. On the other hand, C is a case-sensitive language, which means that the identifiers such as variables, function names, and keywords must be written in the correct case. For example, "main" is different from "Main" and "MAIN" in C. It's important to keep in mind the case sensitivity rules while coding in these languages to avoid syntax errors or unexpected behavior.
Yes. C and C++ are case sensitive, although, depending on implementation, external symbols might not be case sensitive.
Most people use their emails addresses for login names for a variety of reasons. It is easier to remember and unique to each indicidual. Some websites do not allow emails as login names.
