Computer

A structure used for containing and organizing files, documents and software applications and even sub-folders. In some operating systems, it is called a directory. The term is most commonly used with graphical user interface operating systems. Most operating systems, upon right clicking the folder, provide information on the folder along with its properties. A Folder does not take any space, in size, on hardisks and other storage types, it is only a "virtual location" defined on the file system.

Free software is copyright-free software, with no limitations or constraints, but might not be free in the sense that there’s no price attached to it. It can be modified and changed at the will of the user and this means that the user can make changes to the core elements of the program, re-write whatever they want, overwrite things, completely repurpose the program, fork it into new software, etc. This type of software is often called open-source software, or free and open-source software (FOSS).

Software created by people who are willing to give it away for the satisfaction of sharing or knowing they helped to simplify other people's lives. It may be free-standing software, or it may add functionality to existing software. Freeware is a combination of the words "free" and "software" to mean “free software.” The term, therefore, refers to software programs that are 100% free of charge, no kind of fee required.

File Transfer Protocol (FTP) is a network protocol for transferring copies of files from one computer to another remote system. An FTP client is a program that allows you to move files between computers. FTP was developed during the 1970s and 1980s to support file sharing on TCP/IP and older networks. The protocol follows the client-server model of communication.
