Learn English – Difference between “ran into someone” and “bum into someone”

The simplest way to think about these two terms is perhaps,

• to think of a user account as the user himself or herself, and
• to think of his or her profile as information about that user.

Sometimes the two terms are somewhat overlapped.

From Wikipedia,

A user is a person who uses a computer or network service. A user often has a user account and is identified by a username (also user name). Other terms for username include login name, screen name (also screenname), nickname (also nick), or handle, ...

A user profile is a visual display of personal data associated with a specific user, or a customized desktop environment. A profile refers therefore to the explicit digital representation of a person's identity. A user profile can also be considered as the computer representation of a user model. A profile can be used to store the description of the characteristics of person. This information can be exploited by systems taking into account the persons' characteristics and preferences.

From Microsoft,
^{(this is specific to Windows operating system, but the concept is similar to user account and user profile in web programming)}

A user account is a collection of information that tells Windows which files and folders you can access, what changes you can make to the computer, and your personal preferences, such as your desktop background or screen saver. User accounts let you share a computer with several people, while having your own files and settings. Each person accesses his or her user account with a user name and password.

Your user profile is a collection of settings that make the computer look and work the way you want it to. It contains your settings for desktop backgrounds, screen savers, pointer preferences, sound settings, and other features. User profiles ensure that your personal preferences are used whenever you log on to Windows.

A user profile is different from a user account, which you use to log on to Windows. Each user account has at least one user profile associated with it.

^{(emphasis added)}

"Where are you from" is more common (at least in U.S. English). In my opinion, this is the preferred option when meeting someone new.

The difference is a bit more emphasis on the verb "to be/are" instead of the action of "coming/being from" somewhere as is common in other languages. The meaning is identical though.

1) "Where are you from?" implies that you want to know what city/state/country they consider "home," and that you assume it's someplace other than where you are right now. This may be confusing, since where someone is "from" isn't necessarily where they live. It also can be embarrassing to assume, for example, that a person of a certain ethnic background must "come from" some other place. It might be a good idea to separate the idea of "what is your family/ethnic background?" from "where do you live right now?"

"Where are you from?"

"I'm originally from Oslo, Norway, but I live in Chicago."

2) "Where do you come from" sounds kind of awkward and outdated. I think this is because it includes the present-tense verb "do" in a question about a past-tense action (coming from somewhere). This is perfectly understandable and you can say this if you prefer - I'd still suggest the other way though.

"Where do you come from?"

"I come from a land beyond the sea, overrun by trolls and dragons!"

3) "Where did you come from" would be correct if you want to know "where were you immediately before you came to this location we're at right now?" This can also be used to express surprise at the person's sudden arrival or unexpected actions.

"Where did you come from?"

"I was next door, but now I'm here to rescue you!"
