Some devices, such as the hard disc, are physical whereas others, such as a RAMDisc, are
virtual (or, in the case of a ShareFS mount, a portal of another computer's physical or virtual
device being shared over the network and then accessed remotely).
*These ROM-based resources are resident in the Read-Only Memory chips inside the
computer and cannot be erased. They hold the majority of the information required to allow
the computer to function (the operating system). Supplementary resources and software
applications are kept on the hard disc and are utilised in a structured manner when booting
or at any point when using the computer. Click SELECT on the ROMAPPS icon on the Icon
Bar to access those applications held in ROM.
**Random Access Memory Filing System - temporary storage space in the computer's
memory which is lost when the power is switched off incorrectly referred to as a 'RAMdisc'.
Application Icons
The right-hand side of the Icon Bar is generally used to show when a computer program (
also known as an application) is active, by displaying its icon there, and also to allow you to
control the properties of the screen display using the Display Manager, or to manage the
computer's active memory allocation using the Task Manager (these last two features are
always present on the Icon Bar).
The Display Manager allows you to change the size of screen area and the depth of colour
being displayed. The RISC OS 4 cube allows access to the computer's dynamic areas where
you can allocate memory to specific tasks.
Other application icons will appear on the Icon Bar when made active by the user).
