Methods for Software Development, Installation, and Management in Computer Systems and Methods for Controlling Input and Output Data Transfer in Computer Systems

A method for software development, installation, and management in a computer system may include: allowing first users to create components of applications; allowing second users, at a display of a web-browser-capable communications device, to build, edit, save, and compile new applications, using the components of the applications as end-user development tools, and to add the new applications to the library of applications; and allowing the second users, at the display of the web-browser-capable communications device, to download one or more of the new applications from the library of applications to mobile communications devices. When executed by the processor, the stored instructions control the computer system to perform functions that may include: connecting the mobile communications devices in a network using the downloaded one or more of the new applications; and causing information transfer to occur within the network that is independent of the processor of the computer system.
