5 Examples of Storage Devices c:

* A hard disk drive (HDD) is a non-volatile, random access device for digital data. It features rotating rigid platters on a motor-driven spindle within a protective enclosure. Data is magnetically read and written on the platter by read/write heads that float on a film of air above the platters.
* A floppy disk is a data storage medium that is composed of a disk of thin, flexible ("floppy") magnetic storage medium sealed in a square or rectangular plastic carrier lined with fabric that removes dust particles.
* A USB flash drive consists of a flash memory data storage device integrated with a USB (Universal Serial Bus) interface. USB flash drives are typically removable and rewritable, and physically much smaller than a floppy disk.
* A memory card reader is a device, typically having a USB interface, for accessing the data on a memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Most card readers also offer write capability, and together with the card, this can function as a pen drive.
* DVD+RW is a physical format for rewritable DVDs and can hold up to 4.7 GB. DVD+RW was created by the DVD+RW Alliance, an industry consortium of drive and disc manufacturers.

5 Examples of Output Devices :D

* A monitor is the screen on which words, numbers, and graphics can be seem. The monitor is the most common output device.
* Compact Disk, some compact disks can be used to put information on. This is called burning information to a CD.
NOTE: A CD can also be an input device.


* A floppy disk is used to record information on. The information is stored on the floppy disk and can be used later or used on another computer.
* A printer prints whatever is on the monitor onto paper. Printers can print words, numbers, or pictures.
* A speaker gives you sound output from your computer. Some speakers are built into the computer and some are separate.

5 Examples of Input Devices :)

*  Web cam is a camera connected to a PC or server allowing the users to share pictures or videos across the Internet.



                                 




*  A microphone allows you to record sounds and voices to your personal or office computer. The sound card back plate is used to connect the microphone component to the computer. These days integrated microphones come in all laptops and certain desktop models.








*  The keyboard is the main input peripheral used by all computers. It allows for user input and interaction with the computer. Like your conventional typewriters, the keyboard has all the letters of the alphabet, numeric keys from 0 - 9 and additional special keys.



                *  A mouse is a pointing device that functions by detecting two-dimensional motion relative to its supporting surface.     
  *  Universal Serial Bus (USB) is a specification to establish communication between devices and a host controller (usually personal computers), developed and invented by Ajay Bhatt while working for Intel. USB has effectively replaced a variety of interfaces such as serial and parallel ports.

I can't smile without you :)

My expectations to this subject and to our teacher. First, the teacher should give some instructions or procedure that we have to follow. Second, the teacher should be patient enough especially to our class because we are so very noisy. Third, the teacher should be approachable and funny :)

To this subject Information Technology :))
We all know that Information Technology is difficult to learn . I expect that it is gonna easy for me to learn this subject. And the subject should be interesting and not boring.

My experience in using computer is great majority to communicate. For example like facebook we can share our pictures and chatting with our beloved friends Because computer is the best way to communicate with my love ones through internet. And Internet knowledge and experience is another area where you can shine.
