Sim nyeem cov hlua ntawm binary 1's thiab 0's zoo li yog txoj haujlwm nyuaj. Txawm li cas los xij, nrog lub logic me ntsis, peb tuaj yeem paub tias nws txhais li cas. Tib neeg tau yoog raws siv lub hauv paus kaum tus lej yooj yim vim tias peb muaj kaum tus ntiv tes. Ntawm qhov tod tes, khoos phis tawj tsuas muaj ob lub "ntiv tes" - rau thiab tawm, qhib thiab tawm, lossis xoom thiab ib qho. Yog li, lub hauv paus ob tus lej tau tsim.
Kauj ruam
Txoj Kev 1 ntawm 3: Siv Cov Nthuav Tawm
Kauj Ruam 1. Nrhiav tus lej binary uas koj xav hloov pauv
Peb yuav siv qhov no ua piv txwv: 101010.
Kauj Ruam 2. Muab tag nrho cov lej zauv zauv zauv ob los ua ob lub zog rau qhov chaw ntawm tus lej
Nco ntsoov tias binary tau nyeem ntawm sab xis mus rau sab laug. Qhov chaw nyob sab xis yog xoom.
Kauj Ruam 3. Ntxiv cov txiaj ntsig
Cia peb ua nws ntawm sab xis mus rau sab laug.
- 0 × 20 = 0
- 1 × 21 = 2
- 0 × 22 = 0
- 1 × 23 = 8
- 0 × 24 = 0
- 1 × 25 = 32
- Tag nrho = 42
Txoj Kev 2 ntawm 3: Lwm Hom Ntawv nrog Exponent
Kauj Ruam 1. Xaiv tus lej binary
Cia siv 101. Nov yog tib txoj kev tab sis nrog hom ntawv sib txawv me ntsis. Koj yuav pom hom ntawv no nkag siab yooj yim dua.
- 101 = (1X2) rau lub zog ntawm 2 + (0X2) rau lub zog ntawm 1 + (1X2) mus rau lub zog ntawm 0
- 101 = (2X2) + (0X0) + (1)
- 101= 4 + 0 + 1
-
101= 5
'Xoom' tsis yog tus lej, tab sis nws qhov chaw yuav tsum tau muab sau tseg
Txoj Kev 3 ntawm 3: Qhov Chaw Tus Nqi
Kauj Ruam 1. Nrhiav koj tus lej
Qhov piv txwv peb yuav siv yog 00101010.
Kauj Ruam 2. Nyeem ntawm sab xis mus rau sab laug
Rau txhua qhov chaw, qhov txiaj ntsig tau muab ob npaug. Thawj tus lej ntawm sab xis muaj tus nqi 1, tus lej thib ob muaj tus nqi 2, tom qab ntawd 4, thiab ntxiv rau.
Kauj Ruam 3. Ntxiv cov txiaj ntsig ntawm tus lej ib
Zeros muaj lawv qhov txiaj ntsig qhov chaw, tab sis lawv tsis ntxiv.
-
Yog li, hauv qhov piv txwv no, ntxiv 2, 8, thiab 32. Qhov tshwm sim yog 42.
"Tsis yog" rau 1, "yog" rau 2, "tsis yog" rau 4, "yog" rau 8, "tsis yog" txog 16, "yog" rau 32, "tsis yog" rau 64, thiab "tsis yog" rau 128. " Yog "txhais tau tias ntxiv," tsis yog "txhais tau tias hla. Koj tuaj yeem nres ntawm tus lej kawg
Kauj Ruam 4. Hloov qhov muaj nuj nqis rau cov ntawv lossis cim cim cim cim cim cim
Ib qho ntxiv, koj tuaj yeem hloov tus lej los ntawm binary mus rau decimal lossis hloov los ntawm zauv mus rau binary.
Hauv qhov cim tseg, 42 zoo ib yam li lub hnub qub (*). Nyem qhov no rau daim duab
Lub tswv yim
- Binary xam tib yam li cov lej ib txwm. Tus lej sab xis nce mus txog ib qho kom txog thaum nws tsis tuaj yeem nce ntxiv lawm (qhov no los ntawm 0 txog 1), thiab tom qab ntawd nce tus lej tom ntej mus rau sab laug thiab pib dua los ntawm xoom.
- Cov nab npawb peb ua haujlwm nrog hnub no muaj qhov chaw qhov tseem ceeb. Piv txwv tias peb tab tom ua haujlwm nrog tus lej tag nrho, tus lej sab xis yog qhov chaw, tus lej rau sab xis ntawm tus lej yog kaum qhov chaw, tom qab ntawd ntau pua qhov chaw, thiab ntxiv rau. Muab qhov tseem ceeb rau tus lej binary pib nrog ib, ob, plaub, yim, thiab ntxiv rau.
