Vamapoka mashoko

Unit kuripo pose mumunda zvinhu somunhu kwakajairika nerokuti chiyero chinhu. Volume, urefu uye uremu - chinonyanya zvinowanzovapo munazvo. Mumakondinendi siyana, mumitauro yakasiyana-siyana, zvisinei nechitendero, tinoshandisa zvakafanana nerwodzi zvinoreva. Nokuti murume zviri nyore, kuwana uye unonzwisisika, izvozvo hakurevi chero chinhu kuti mudzoke, izvo zvinowanzoita kuti zvikanganiso.

Nengano kwatombova nekombiyuta muupenyu hwomunhu, panewo chikonzero kusika chimwe chikwata kwouwandu hwezvinhu mashoko. Hongu, zvakadai kuti kunonzwisiswa uye Chinese, uye American, uye chero kombiyuta munyika. programmers All zvenyika kurishandisa sezvo mutauro nevakawanda. Saka pakanga zvishoma pamusoro binary logarithm.

Ikakuruma - chairema mashoko akaenzana nhamba ruzivo uye kuzvitutumadza tsika mbiri chete "riri" uye "kubvisa" (ifananidzwe 1 uye 0). To kombiyuta encode ari Chirungu arufabheti, zvitanhatu matomu zvakakwana, asi nekuda kuzadziswa zvikuru kunzwisisa zvirongwa muitiro zvinoda zvakawanda Vhoriyamu mashoko zviumbu kuti akakweretwa kubva muchiLatin chivakashure masvomhu. Matomu kombiyuta - iri imwe zvemagetsi kupomba iri kusvitsa kubva murayiro pambiru kune varikutonga muviri uye itirana KUDA basa rinoitwa. 0 1 mirayiro vari zvakasiyana voltage neeSultan. Izvi zvose zviri kuitika panguva yakadaro kumhanya, kufanana kuchinjwa mashoko pakati uropi uye tsinga harinzwi mumuviri womunhu.

mitauro All zvirongwa akasungwa kuna binary romutemo. Photos Kutamiswa kupinda zvemagetsi chimiro, mitambo uye Software chirongwa chipi, kurapa michini kugadzirwa - zvose kushandisa vanhuwo mashoko muzvikamu - wedzeredzei.

Kuunganidza mu pulses cheni matomu kuti kuumba mashoko matsva kuyera Unit: BYTES, kilobits, kilobytes, megabits, megabytes, gigabytes, terabytes, PB uye zvichingodaro.

Byte uneshongedzo yokuva matomu sere uye ane zita rechipiri - octet sezvo munhoroondo kombiyuta pane mhinduro sezvo ane 6-ikakuruma bytes uye 32-yati, asi chete-software mhinduro vamwe makambani ari kuvandudzika mashoko chikwata asina kupiwa unobereka zvibereko. Asi chikuru pane masere ikakuruma byte, rinonzi saka zita nevakawanda "octet".

Kuti zviite nokurera mashoko, nhamba vezvikwata mashoko encoded mu zvikuru anotenderwa tafura mhando Unicod, uye dzimwe mhando Coding kushandisa Windows Os kana mumwe. Mumwe nomumwe matafura rinoshandiswa kuti chinangwa chahwo. Nokuti mufananidzo-chena dema-uye kushandisa imwe 8-yati binary system uye ruvara kwava 24-wedzeredzei. Kunyora rugwaro chero mutauro wenyika kushandisa 16-ikakuruma UNICOD zvakakwana.

Panguva iyoyo, avhareji User rinowanikwa tasam guru chairema mashoko ari terabyte - ndizvozvo 1,024 gigabytes, izvo vanoumba, akavapindurawo, 1024 gigabytes. Kana kuwanda kubudikidza 1024, tinowana uwandu megabytes hunoumba mumwe terabyte. Kana chokuwanziridza nyore zvakadaro akaramba kusvikira kwokutanga Unit, ipapo kutsauka nezuva rokutanga, chero karukureta hakukodzeri. Izvi zvichava uwandu binary Codes kuti vaifanira kuzadza rino.

Kutaura zvazviri, vagadziri vakawanda yenhengo wakashandiswa issuance iri chaiyo zvinoreva prefixes churu, Mega uye giga. Izvi zvinotungamirira zvinokosha zvikanganiso uye rakafukidzwa unyengeri. Kureva kuti zvakaoma dhisiki 1 terabyte utano anogona kuchengeta vanosvika 950 megabytes ose mashoko. Computer vemunharaunda kare akapa nzira yokudzivisa nayo.

Prefixes churu, Mega, uye zvichingodaro kuramba yavo yekushandisa zvinhu. Churu - chiuru, Mega - miriyoni. Nokuti midziyo kombiyuta zvakanaka kushandisa multiplier haasi 1000, uye 1024. The zita iye kutanga - KIBI. Kureva zvakarurama prefixes uye multipliers ndiwo: kibi-, mibi- uye mberi.
