Nyob rau hauv cov ntaub ntawv no peb xav txog cov nqe lus nug ntawm yuav ua li cas npaum li cas cov ntaub ntawv no muaj nyob rau hauv ib tug tus neeg tau txais cov lus. Ntawm no nyob rau hauv lub chav kawm yog cov theorem ntawm discrete lej. Los mus laij lub ntim ntawm lub ntsuas uas muaj ntaub ntawv yog npaum li cas ob tug sib txawv qauv nyob rau lub ntau yam ntawm ib tug tshwm sim. Nyob rau tib lub sij hawm nyob twj ywm rau hauv tib lub chav tsev ntawm cov ntaub ntawv nyob rau hauv computer science. Qhov teeb meem ntawm kev xam tus naj npawb ntawm cov cim, cov graphics rau lub substantive mus kom ze yog ntau npaum li cas dua alphabetical.

Hom ntawm cov ntaub ntawv dab

Muaj peb hom dab pom nyob rau hauv ib tug hluav taws xob computer:

1. Cov ntaub ntawv ua. Yuav ua li cas yog tus txheej txheem no? Los ntawm cov cuab yeej ntawm cov ntaub ntawv nkag teb chaws, seb puas keyboard, kho qhov muag nas, tshuab luam ntawv, los yog lwm yam ntaus ntawv, lub computer tau txais ntaub ntawv. Ces converts lawv mus rau hauv binary code, thiab sau ntawv mus rau ib qho nyuaj tsav nyob rau hauv me me, bytes, megabytes. Yuav kom txhais tej ntaub ntawv rau lwm muaj ib lub rooj nyob rau hauv lub computer, nyob rau hauv uas koj yuav tau xam ntau npaum li cas nyob rau hauv ib tug megabyte me ntsis, thiab ua lwm yam kev hloov tsheb. Lub computer yog txhua yam yeej.
2. Khaws cia cov ntaub ntawv thiab cov ntaub ntawv nyob rau hauv lub cim xeeb. Lub computer yog tau cim txhua yam nyob rau hauv binary daim ntawv. Binary code muaj zeros thiab sawv daws yuav.
3. Ib tug ntawm cov tseem ceeb dab nyob rau hauv lub tshuab hluav taws xob computer - cov ntaub ntawv kis tau tus mob. Nws kuj tau nyob rau hauv binary daim ntawv. Tab sis nyob rau qhov kev tshuaj ntsuam cov ntaub ntawv no tso tawm kom pom twb nyob rau hauv lub cim los yog lwm cov li ib txwm rau peb xaav ntawm daim ntawv no.

Coding ntaub ntawv, thiab cov kev ntsuas ntawm nws cov kev ntsuas

Lub tsev tau txais ntaub ntawv me me, uas yog ib qho yooj yim txaus mus ua hauj lwm, vim hais tias nws muaj peev xwm tuav ib tug nqi ntawm 0 los yog 1. Raws li cov computer encodes li ib txwm decimal xov tooj mus rau hauv binary code? Xav txog ib tug me me qauv, uas piav txog lub hauv paus ntsiab lus ntawm coding ntaub ntawv nrog computers.

Piv txwv peb muaj ib tug xov tooj nyob rau hauv lub li ib txwm calculus - 233 . Yuav kom txhais nws rau hauv binary, nws yog tsim nyog los faib los ntawm 2 mus txog rau thaum tej lub sij hawm raws li nws yuav me dua cov divisor (nyob rau hauv peb cov ntaub ntawv - 2).

1. Tau division 233/2 = 116. Tshuav kaw nyias, nws yuav yog ib feem ntawm cov lus teb ntawm lub binary code. Nyob rau hauv peb cov ntaub ntawv nws yog 1.
2. Qhov thib ob kev txiav txim yog yuav tsum tau 116/2 = 58. Cov seem ntawm lub division - 0 - dua sau nyias.
3. 58/2 = 29 tsis muaj ib tug seem. Tsis txhob hnov qab sau lub seem 0, vim hais tias, muaj poob tsuas yog ib lub caij, koj tau txais ib yam nkaus magnitude. Qhov no code yuav tau txais kev khaws tseg rau koj lub computer tsav nyuab thiab yog ib tug me me - qhov tsawg kawg nkaus unit ntawm cov ntaub ntawv nyob rau hauv lub computer. 8 qib yog twb tau tiv nrog cov kev hloov ntawm cov zauv xov tooj mus rau hauv binary hom muab xam, thiab vice versa.
4. 29/2 = 14 nrog seem 1. Nws txoj kev ntawv thiab sau ntawv nyias mus lub twb tau binary tug lej tom qab.
5. 14/2 = 7. Cov seem ntawm lub division yog 0.
6. Ib me ntsis ntxiv, thiab lub binary code yuav npaj txhij. 7/2 = 3 nrog ib tug seem 1, uas cov ntaub ntawv thiab ib tug yav tom ntej teb binary code.
7. 3/2 = 1 nrog ib tug seem 1. Qhov no cov ntaub ntawv nyob rau hauv cov lus teb rau ob units. Ib tug - raws li cov seem, cov lwm yam - li lub xeem ntxiv xov tooj uas tsis yog divisible los ntawm 2.

Nws yog tsim nyog los nco ntsoov tias cov lus teb yog sau nyob rau hauv rov qab kev txiav txim. Thawj, tau txais cov binary tooj ntawm cov thawj kauj ruam yuav tsum yog qhov kawg zauv ntawm lub thib ob - tus penultimate, thiab hais txog. Peb kawg cov lus teb - 11101001 .

Qhov no binary tus xov tooj yog sau ntawv mus rau lub cim xeeb ntawm lub computer thiab muab cia rau hauv daim ntawv no kom txog thaum tej lub sij hawm raws li tus neeg siv tsis xav kom mus saib nws los ntawm qhov screen. Khoom, bytes, megabytes, gigabytes - lub tsev ntawm cov ntaub ntawv nyob rau hauv computer science. Nws yog nyob rau hauv cov qhov tseem ceeb thiab binary cov ntaub ntawv khaws tseg nyob rau hauv lub computer.

Rov qab translation ntawm tus xov tooj ntawm binary rau decimal system

Nyob rau hauv thiaj li yuav effect rov qab hloov lwm lub tsev ntawm lub binary qhov tseem ceeb nyob rau hauv lub decimal system, nws yog tsim nyog los siv lub mis. Suav cov xov tooj ntawm tug lej tom qab nyob rau hauv lub binary nqi pib los ntawm 0. Nyob rau hauv peb cov ntaub ntawv 8, tab sis yog hais tias peb pib suav ntawm xoom, ces nws xaus ib theem zuj zus tooj 7. Tam sim no yuav tsum txhua tug lej ntawm lub code yog multiplied los ntawm 2 lub hwj chim ntawm 7, 6, 5, ..., 0.

^{1 * 2 7 + 1 * 2} 6 + 1 * 2 5 + 0 * 2 4 + 1 * 2 3 + 0 * 2 2 + 0 * 2 1 + 1 * 2 0 = 233 . Qhov ntawd yog peb tej noob, uas yog coj mus rau hloov lwm lub tsev nyob rau hauv ib tug binary code.

Tam sim no koj paub lub essence ntawm cov ntaub ntawv encoding lub xam ntaus ntawv thiab qhov tsawg kawg nkaus ntaub ntawv cia ntsuas.

Qhov tsawg kawg nkaus unit ntawm cov ntaub ntawv: hauj lwm

Raws li hais saum toj no, tus nqi qis tshaj tus nqi yog hais tias yuav ntsuas ntaub ntawv me me. Lo lus no yog lus Askiv keeb kwm, txhais nws txhais tau tias "binary lej". Yog hais tias koj saib nyob rau ntawm no muaj nqis, rau lwm cov tes, peb yuav hais tias qhov no yog ib tug nco cell nyob rau hauv lub tshuab hluav taws xob computers, uas yog cia nyob rau hauv daim ntawv ntawm 0 los yog 1. khoom yuav muab txhais mus rau hauv bytes, megabytes, thiab txawm loj qhov ntau ntawm cov lus qhia. Hauv computer nws tus kheej koom nyob rau hauv xws cov txheej txheem, thaum khaws cia ib tug binary cai nyob rau hauv lub cim xeeb ntawm lub zog tsav.

Ib txhia computer cov neeg siv tej zaum yuav xav kom manually thiab sai sai txhais kev ntsuas ntawm cov ntaub ntawv los ntawm ib tug mus rau lwm lub. Rau xws li cov hom phiaj, online cov cav laij leb tau tsim, lawv yuav nqa tawm no ob lub lag luam, uas manually yuav siv ib tug ntau lub sij hawm.

Chav ntawm cov ntaub ntawv science: ib lub rooj ntawm qhov tseem ceeb

Computers, flash drives thiab lwm yam nco kiag li lawm thiab cov lus txawv nco peev xwm, uas yog feem ntau nyob rau hauv xam gigabytes. Nws yog tsim nyog los saib lub ntsiab lus tseem ceeb rau saib comparability ntawm ib tug ntaub ntawv tsev nyob rau hauv computer science nyob rau hauv ascending thiaj li los ntawm lub thib ob.

Siv cov nyiaj pab ntau tshaj cov lus qhia unit

Nyob rau hauv peb lub sij hawm, ib qho kev ntsuas ntawm qhov ntau tshaj ntawm cov ntaub ntawv, uas yog hu ua yottabaytom, yuav siv lub National Security Agency nyob rau hauv thiaj li yuav khaws tag nrho cov suab thiab video ntaub ntawv tau txais los ntawm pej xeem chaw nyob qhov twg video koob yees duab thiab microphones. Thaum no tus taw tes yottabayty - qhov loj tshaj plaws chav tsev ntawm cov ntaub ntawv nyob rau hauv lub computer. Qhov no yog cov kev txwv? Nws yog tsis zoo li hais tias ib tug neeg yuav tsum tau muab ib qho tseeb teb txoj cai tam sim no.
