Aread-only file is one that you are prohib- ited from editing or deleting. A file can have read-only status if:

‡Its read-only attribute is enabled.

The rate at which the monitor redraws the video image on the monitor screen. More precisely, the refresh rate is the frequen- cy, measured in Hz, at which the screen’s horizontal lines are recharged (sometimes also referred to as its vertical frequency).

SDRAM devices have a synchro- nous interface to the devices to which they are connected and are governed by the system clock. These features reduce the need for wait states often required for conventional memory devices to ensure
