communications software - Computer Definition
Software that assists a computer operating system (OS) in managing local and remote terminal access to host resources, managing security, and performing certain checkpoint activities. Communications software generally is embedded in the OS, although it can take the form of a systems task under the control of the OS. Communications software, for example, is used to control a modem, performing terminal emulation and file transfer tasks. See also host, modem, OS, terminal, and terminal emulation.
