Ang computer ay isa sa mga pinaka-kahanga-hangang produkto ng modernong science. Ito ay gumaganap ng isang mahalagang papel sa modernong buhay. PC gumagana sa hindi kapani-paniwala kawastuhan bilis, at katumpakan. Maaari itong gumawa ng libo-libong mga kalkulasyon sa bawat segundo. Ito ay isang elektronikong makina computing na maaaring count, isulat at malutas ang napaka-komplikadong problema. Computers ginawa paraan para sa bawat tao na aktibidad. Ito ay isang kaibigan ng mag-aaral, negosyante, industrialists, siyentipiko at iba pa.

Ang salita computer ay mula sa salita compute ang kahulugan para sa mga pagkalkula. Nakakatagpo kami ng mga computer sa opisina, negosyo bahay, laboratories at sa ships. Hindi namin kailangang maghintay sa linya para sa isang mahabang panahon ngayon. Tiket ay ibinigay sa pamamagitan ng computer. Computers ginawa buhay mas madali at perpekto.

Neolitiko istraktura ng Stonehenge malapit sa Salisbury sa England ay regarded bilang isang senior computer. Ito ay inilaan upang ay binuo tungkol sa 4000 taon na ang nakakaraan. Ito ay binubuo ng isang pabilog na istruktura ng mga bato para sa mga templo na nakatuon sa sa araw diyos. Ito ay ginamit upang mahulaan astronomikal na phenomena tulad ng iba’t-ibang mga planetary orbit. John Napier (1552 – 1617) sa pamamagitan ng logarithm ng multiplikasyon at dibisyon ng mas madali. Slide patakaran ay isang extension ng logarithm. Ay ang pangalan ng siyentipiko Charles Babbage imbento ng modernong computer sa ikalabinsiyam siglo. Sa unang yugto ng mga computer na ginamit vacuum tubes. Ang ilang taon mamaya, Dr Howard Alken mula Harward University para sa awtomatikong calculator sequence kontrolado – ang unang mechanical computer.

Mayroong dalawang mga computer na mga modelo, katulad analog at digital – ang dating mga panukala, at Calculator. Ngayon, ang mga digital na mga computer ay mas tanyag. Digital Latin salita para sa daliri. Sa nakaraan, mga daliri ay ginamit upang count. Computers ay ginagamit upang maisagawa ang napaka-komplikadong gawain. Sila ay ginagamit upang kontrolin ang direksyon ng Rockets at missiles. Tulad mga computer ay ginagamit sa World War II. Karamihan sa pananaliksik ay tapos na upang mapagbuti ang mga umiiral na mga bago.

Ang isang computer program naka-code na mga tagubilin para sa computer upang sundin. Ang program na ito ay isinulat na tinatawag na computer programming. Computer, kasama ang lahat ng pagiging sopistikado at katangi-tangi kakayahan upang maisagawa ang mga gawain ay hindi maaaring palitan ang mga tao. Hindi ito maaaring sa tingin para sa mismo. Maaari lamang ito isagawa ang mga gawain, programa namin ito. Computer ay maaaring kontrolin ang kilusan ng mga electron modelo at ang ninanais na imahe ay sa screen ng TV imahe screen ay nabuo bombarding electron. Ngayon, ang computer ay ginagamit upang gumawa ng isang tumpak pagguhit sukatan ng isang maikling oras. Maaari silang lumikha ng mga larawan, card, et. Computers ay ginagamit din satellite upang mahulaan ng panahon. Ospital, ang computer sa pagpapadala ng mensahe sa mga doktor tungkol sa kalagayan ng pasyente.

Maraming mga tao ay nangangamba na ang mga computer, na humahantong sa kawalan ng trabaho. Ito ay mali. Sa katunayan, mga computer upang lumikha ng mga trabaho. Sa ganitong lumalagong mundo, gusto namin ang aming mga gawain ay tapos nang mabilis at tumpak. Bagong teknolohiya sa mga pangangailangan ng produksyon ng mga bagong machines, data, kapangyarihan aparato at elektronikong instrumento, ang produksyon ng mga na nangangailangan ng higit pa at mas lalaki. Kung trabaho mga pagkakataon ay nabawasan sa isang lugar, ito ay nadagdagan sa maraming iba pa.

Kaya hindi namin dapat maging masyadong nag-aalala tungkol sa pagpapakilala ng mga computer. Lumikha ng mga pagkakataon nila trabaho para sa mga tao sa marami pang ibang lugar. Sa katunayan, mga computer ay pagpunta sa gawin sa amin karamihan ng aming mga trabaho sa ika-21 siglo.
