Windows 10 is a personal computer operating system developed and released by Microsoft as part of the Windows NT family of operating systems.

It was officially unveiled in September 2014 following a brief demo at Build 2014.

The first version of the operating system entered a public beta testing process in October, leading up to its consumer release on July 29, 2015.

An Internet forum, or message board, is an online discussion site where people can hold conversations in the form of posted messages.

They differ from chat rooms in that messages are often longer than one line of text, and are at least temporarily archived.

Also, depending on the access level of a user or the forum set-up, a posted message might need to be approved by a moderator before it becomes visible.

A user is a person who uses a computer or network service.

Users generally use a system or a software product without the technical expertise required to fully understand it.

Power users use advanced features of programs, though they are not necessarily capable of computer programming and system administration.

A computer file is a computer resource for recording data discretely in a computer storage device.

Just as words can be written to paper, so can information be written to a computer file.

Information is that which informs.

In other words, it is the answer to a question of some kind.

It is thus related to data and knowledge, as data represents values attributed to parameters, and knowledge signifies understanding of real things or abstract concepts.

As it regards data, the information's existence is not necessarily coupled to an observer (it exists beyond an event horizon, for example), while in the case of knowledge, the information requires a cognitive observer.
