Paano Nagstart ang aking Computer Career???
Ang Aking Computer Career Nagstart to Since i was in elemetary nong ako ay nang nasa elemetary pinatuturuan ako ang aking naynay ng piano ang nagtuturo sakin ng piano ay isang matandang matandang babae isang araw tinuruan ako ng matanda nang tinuturuan ako pag ako ay nagkakamali ay pinipilipit yung aking kamay minsan pa pag yung binti ko ay nanginginig pinapalo nya at sinasabi may sakit ka ba napaka teror damaan ang mga araw ganon parin pinpilipit yung daliri ko hinihila nya pataas ewan ko siguro ginagawa nya nyo para lumanbot yung kamay ko kaya lang dahil sa natakot ako pagdumadating sya sa bahay nagtatago ako hehehehe yung pinsan ko na kapitbahay ko dati ay may computer shop kaya don ako pumupunta para magtago at pagnandon ako ay pinapalaro nya ko ng computer ang uso pang OS non ay win 95 kaya lang mas uso pang gamiting dati ay dos command ang nilalaro kong computer my 486 tapos yung diskette dati yung malaki hehehehehe 5 1/2 ata yon dati kase pag may floppy 3 1/2 ka pwede ka nang magyabang ngayon ang uso ay yung usb flash drive saka sdcard alam nyon kung ako yung nilalaro ko dati yung usong laro packman saka mario hehehehehe kaya nga experto ako sa dos command kaya nang ng highschool madali lang sakin yung mga tinuturo ng titser ko lalo na yung lotus 123 manok lang sakin yung lotus 123 pala ay parang exel sa dos command lang sya hehehehehe kaya simula non naging hilig ko na yung computer pero kung pinagpatuloy ko siguro yung piano lesson ko siguro magaling na pianista na ko kaya lang ganon talaga ang kapalaran kanyakanyang linya nalinya tuloy ako sa computer hehehehehehehe!!!!!!!!!!!!!
