Keeb kwm ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb ntawm keeb kwm ntawm kev tsim hluav taws xob. Kev siv tshuab hluav taws xob, ib qho cuab yeej tshiab uas tau pib tsim nyob rau xyoo 19th thiab thaum ntxov 20th centuries, pom nws txoj kev loj hlob sai tshaj plaws thiab siv dav tshaj plaws nyob rau hauv lub xyoo pua 20th, dhau los ua qhov tseem ceeb ntawm kev tshawb fawb thiab thev naus laus zis niaj hnub no.
Xyoo 1906, American inventor John De Forest tau tsim lub tshuab nqus tsev vacuum. Thawj tiam ntawm cov khoom siv hluav taws xob tau nyob ib ncig ntawm lub tshuab nqus tsev. Thaum xyoo 1940s, lub ntiaj teb thawj semiconductor transistor tau tsim. Nws qhov me me, kev txav mus los, kev siv hluav taws xob, thiab kev ua neej ntev tau coj mus rau nws txoj kev saws sai los ntawm ntau lub teb chaws, feem ntau hloov lub tshuab nqus tsev vacuum.
Thaum xyoo 1950s, lub ntiaj teb thawj zaug kev sib koom ua ke tau tshwm sim. Nws ua ke ntau cov transistors thiab lwm yam khoom siv hluav taws xob mus rau ib qho silicon nti, ua rau cov khoom siv hluav taws xob me me. Integrated circuits tau hloov zuj zus los ntawm me me- nplai kev sib xyaw ua ke mus rau loj- nplai kev sib xyaw ua ke thiab heev-loj- nplai kev sib xyaw ua ke, tsav cov khoom siv hluav taws xob mus rau kev ua haujlwm siab, kev siv hluav taws xob tsawg, siab precision, siab ruaj khov, thiab kev txawj ntse.
Txij li thaum plaub theem ntawm kev txhim kho hluav taws xob hauv computer zoo kawg nkaus qhia txog cov yam ntxwv ntawm plaub theem ntawm kev tsim kho tshuab hluav taws xob, cov hauv qab no yuav piav qhia txog cov yam ntxwv ntawm plaub theem ntawm kev tsim kho tshuab hluav taws xob los ntawm kev tshuaj xyuas plaub lub sij hawm ntawm kev tsim hluav taws xob hauv computer.
Kev lag luam khoom siv hluav taws xob, uas tau tshwm sim thiab tsim sai heev nyob rau hauv lub xyoo pua 20th, coj kev hloov pauv loj heev rau tag nrho lub ntiaj teb thiab tib neeg txoj haujlwm thiab kev ua neej. Keeb kwm ntawm kev txhim kho cov khoom siv hluav taws xob yog, hauv qhov tseem ceeb, keeb kwm ntawm kev lag luam hluav taws xob.
