Storage Media Any device or material on which data can be electronically placed, kept and retrieved. Examples: Diskette or Floppy Disk Hard Disk Thumb Drive/Pen Drive CD-ROM

Diskette or Floppy Disk One of the oldest removable media solutions available for PC. Ideal as a portable storage solution for small files. Data is stored in a thin plastic disk. Can be easily bent, scratched and cannot withstand heat.

Diskette Do’s and Don’ts Use the envelope provided to cover your disk. Do not touch the inside black plastic disk. Use the soft tip pen to write on the diskette surface. Do not bend or fold the diskette. Keep disks out of direct sun heat which will bundle the diskettes. Do not apply any force/pressure on the diskette surface. Keep disks away from magnets/static electronically.

Hard disk Stores information on a platter. Ideal as a portable storage solution for large files. Vibration or shock can cause surface of the disk to be scratched.

Thumb Drive/Pen Drive A portable USB flash memory device that can be used to quickly transfer audio, video, and data files from the hard drive of one computer to another. Stores information in memory chips. Keep away from static electricity and humid places (e.g. pockets).

CD-ROM Stands for ‘Compact Disc Read Only Memory’. Information stored inside cannot be changed. Made up of a special plastics with a metallic coating. Maximum storage capacity is 700MB Commonly used to store text, audio and video information. Usually 10-15 times slower than hard disk drives. CD-Recordable drives allow you to store your own information on CDs. The Writeable CDs (CD-RW) are generally used to backup hard disks or distribute information.

CD-ROM Do’s and Don’ts DO DON’Ts When handling a CD-ROM, hold the disk around the edge. Do not write on a CD-ROM with a pen/pencil/marker pen. Place the CD-ROM in its casing after use. Do not expose CD-ROMs to dust or dirt. Store CD-ROMs at normal temperature. Do not expose CD-ROMs to direct sunlight. Insert a CD-ROM gently into the CD-ROM drive by holding the edge. Do not peel off the label on a CD-ROM.
