Pepohon cintaku kian merimbun
Semakin dicantas makin bertunas
Tidak mampu mendustai hatiku
Rasa cinta fitrah manusia

Siapalah aku menolak cinta
Yang hadir di jiwa tanpa dipaksa
Hidup ini tidak akan sempurna
Tanpa cinta dari Tuhan Yang Esa

Adam Hawa bercinta di Syurga
Angkara iblis terpisah menderita
Kerana cinta mereka setia
Bertemu di dunia

Dengan cinta kenal Pencipta
Dengan cinta kenal RasulNya
Kerana cinta kenal saudara
Bahagia keluarga
Oh indahnya cinta

Hidup tanpa cinta
Sengsaralah jiwa
Sengketa dan dusta
yang merajai jiwa

Di batasan cinta syariat terjaga
Tanpa keraguan tanpa kesangsian

Betapa sucinya kasihMu Tuhan
Betapa agungnya kebesaranMu
Diri ini mengharapkan cintaMu
Kekalkanlah rasa kehambaan ku

Advantage and Disadvantage of various data storage devices?

 
Hard Disk

Advantages
*Usually integrated into the PC, very robust

Disadvantages
*Slower computer performance when full

Floppy Disk

Advantages
*Inexpensive

Disadvantages
*Very limited capacity
*Easily damaged
*Spreads viruses


CD-ROM/CD-R/CD-RW

Advantages
*Very large storage capacity
*Inexpensive
*Some types can be reused (CD-RW and CD-R)

Disadvantages
*Some older computers cannot read CD-RW media
*Some CD-R discs are 'write once', which means once data is copied across, new or additional data cannot be added

Zip Disk

Advantages
*Large storage capacity
*Disks are durable, robust and rewriteable
*Inexpensive

Disadvantages
*Requires a zip drive, which may not be integrated into the PC. If not, a stand-alone zip drive is required.

DVD
DVDs, or digital versatile discs, are predominantly used as a storage medium for movies, rather than as a general storage medium. They look and operate similarly to a CD-ROM, but they have a much greater storage capacity (up to 17GB).

Type of Device Storage ?




  • There are two storage devices used in computers; a primary storage device such as computer RAM and a secondary storage device such as a computer hard drive. The secondary storage could be a removable, internal, or external storage. In the picture to the right, is an example of a Drobo, an external secondary storage device.

  • Without a storage device, you and your computer would not be able to save any settings or information and would be considered a dumb terminal. Below, are some additional examples of storage devices that are used with computers.

What is Storage Device ?

 
 
  • A data storage device is a device for recording (storing) information (data). Recording can be done using virtually any form of energy, spanning from manual muscle power in handwriting, to acoustic vibrations in phonographic recording, to electromagnetic energy modulating magnetic tape and optical discs.

  • A storage device may hold information, process information, or both. A device that only holds information is a recording medium. Devices that process information (data storage equipment) may either access a separate portable (removable) recording medium or a permanent component to store and retrieve information.
