A CD-RW compact disc (CD-RWs) can be written, read, erased, and re-written. CD-RWs, as opposed to CDs, require specialized readers that have sensitive laser optics. Consequently, CD-RWs cannot be read in many CD readers built prior to the introduction of CD-RW. CD-ROM drives with a "MultiRead" certification are compatible.
The media was compatible with existing CD drives, allowing music and data to be recorded and then read in any existing drive. Over time, this became known as CD-R . [ 9 ] In 1990, the Orange Book added magnetic-optical re-writable versions of the CD physical format, CD-MO , which differed from earlier MO systems primarily in that the disk was ...
This means the heads cover more distance per unit of time on the outer tracks than on the inner tracks. This method is typical with computer hard drives. Constant linear velocity (CLV) keeps the distance covered by the heads per unit time fixed. Thus the disk has to slow down as the arm moves to the outer tracks. This method is typical for CD ...
ROM and RAM are essential components of a computer, each serving distinct roles. RAM, or Random Access Memory, is a temporary, volatile storage medium that loses data when the system powers down. In contrast, ROM, being non-volatile, preserves its data even after the computer is switched off. [2]
A modern PC is configured to attempt to boot from various devices in a certain order. If a computer is not booting from the device desired, such as the floppy drive, the user may have to enter the BIOS Setup function by pressing a special key when the computer is first turned on (such as Delete, F1, F2, F10 or F12), and then changing the boot order.
