EXAMPLES OF STORAGE DEVICES

Hard disk drives are magnetic, non-volatile computer storage devices. A hard disk drive stores data on two spinning platters inside the drive.

Tape drives are another type of magnetic computer storage devices. Instead of platters, the tape drives use magnetic tape to record data.

Optical disc drives include CD, DVD, and Blu-ray. When a disc is inserted into an optical drive, the drive's laser is focused on the disc by the lens on the drive.

"Expectation"

                Way back in my fourth year high school time I choose computer as my elective in T.L.E our instructor taught us how to use adobe Photoshop, Editing pictures and a sort background knowledge about computer but I know It's not enough though it helps me a lot.

                One day I try to use Adobe Photoshop and sad to say I already forgot how to use the tools and some of use of it,thats why I expect that I will learn new things as the time goes since this subject Introduction to information Technology talks not only about computer.I hope that our instructor will impart his knowledge through teaching us well and lastly he will not be thrifty when it comes to grade because I know he has a Big heart and he will gave what we deserve to have.

" Computer addiction"

             Since I stepped in Elementary I've been curious and fascinated to the fast changing world of computers When I first saw a  Bighead computer set (I was actually talking about to an old model monitor)  I really want to hold and move the mouse, I want to play with it and explore what's within the computer, We don't have our own computer by that time we just go at the computer shop to use a computer and pay per hour I learn playing different online games like Counter Strike, Diablo , Warcraft, Dota and many more I go their every after our class and even early in the morning I spent a lot on renting computers rather than spending my time and money at school then I learn how to cutting classes because of this it became my habit and that time for me my day isn't complete without seeing, touching and playing computer and the result majority of my academics subject failed!!!

          

                That's why I'm not wondering that my mom given me only snacks in my classes time because she knows if she given me a pocket money it will just go to my vices suddenly I realized my life becomes worst and full of regrets will it because I was being a computer addict that time..

               

                But as the time goes by I appreciate the real beauty and importance of fast changing world and now I'm already a college I wanna learn how to edit pictures making designs, making programs and many more and lastly to dealt with our society right now.
