Yintoni ikhilobhayithi? Ukuguqulela badinga kwi kilobytes

Iikhompyutha ngokuqinileyo yinxalenye yobomi bethu, nangona yokuba kwiminyaka 10-15 edlulileyo babebonakala yayinqabile, ethi ifumaneke kwi ezimbalwa. Kwaye isizukulwana esitsha ngendlela engcono owayesazi ubuchwepheshe obutsha. Kodwa wonke umntu ukujongana iikhompyutha, kufuneka ngokwemiqathango ethile Akucaci ke ukuba yonke: le bytes, megabytes, gigabytes njalo njalo. Ke ngoko, nakanjani kukho imibuzo eyahlukeneyo: yintoni na ikhilobhayithi, indlela ukuguqula unit enye ukuya kwenye, njalo njalo.

ulwazi

Ulwazi namhlanje ilinganiselwa ngaphezu kwayo yonke enye into, kwaye nawuphi na umntu mihla luhlobo isixhobo. Oku kakhulu phakathi kweenkampani ezinkulu kwiinkalo ezahlukeneyo ehlabathini. Ke ukuba eli hlabathi iikhompyutha, apho kwaziswa iyunithi yayo, yaye nabani na onomdla xxi technology ngenkulungwane, kufuneka nje ukwazi kubo.

Iinkcukacha ezigcinwe kwi khompyutha ngokusondeleyo inxulumene kakhulu kwisixhobo hard disk. Nabanina izixhobo ekhaya, kungekudala ucinge ukuba oko kuyasebenza kwaye ezinye iinkalo eziphambili indlela. Kule ndaba bookshops unako ukufumana iincwadi ezininzi kweli nqaku mabangapheleli ngokwethu hard drive.

indawo yediskhi esekhompyutheni - indawo yokugcina ulwazi ngekhompyutha

ikhompyutha nganye okanye kwi laptop yakho unalo idiski nzima ukuba likhaya lonke ulwazi lwedijithali. Kwaye phambi kokuba uphendule lo mbuzo, yintoni na ikhilobhayithi, unokukhangela ngaphakathi baqonde indlela iinkcukacha igcinwa. Ngaphakathi isixhobo kukho motor block yombane eziquka ezininzi Disks (enekuku), apho zicwangciswe ngentla kwentloko kunye nesethi ingcingo wesekethe.

Nto layiva kakuhle, phambi keyiki baba ubuncinane-2, oko kukuthi, inani lawo elipheleleyo zafikelela-4 okanye ngaphezulu. drives Modern kunzima nkqu enkulu umthamo babe enekuku 1 okanye 2, nangona kwiimeko ezininzi elinye kuphela. Oku kungenxa kusetyenziso lweeteknoloji mihla kwimveliso nzima drives, ngenxa apho kwenzeka ukunciphisa ukurekhoda mninzi. Ngamanye amazwi, le keyiki zimbalwa, kwaye umthamo ulwazi ibhalwe ngaphezulu. drives Modern nzima ukuya terabytes-2 okanye ezi-3 nabo sele ziqulathe libiza enye.

Ke kaloku, waguqukela umbuzo wokuba yintoni kilobytes, uyakwazi ukuthetha oku kulandelayo. Ngalinye libiza hard diski ejikelezayo kwi ngesantya esiphezulu apho 5 okanye 7 amawaka ngomzuzu. Kuba drives hard, iiseva, eli nani ukunyuka ukuba 10000. Kuyaphawuleka, kodwa musa ukuchukumisa intloko enekuku wafukama phezu kwabo, ngenxa yokuba ukutyabeka obhityileyo eyonakeleyo lula.

Kwi hard disk naziphi na iinkcukacha ezifakwe iibhloko. A libiza ngalinye abaphawulwe emkhondweni concentric, nganye yahlulwe kumacandelo ukungaqukathi bytes ngaphezulu kwe 512 yolwazi. Chain kwamacandelo ezilandelelanayo zakha ezisebenzisanayo. Zonke iintloko ukuhamba ngexesha elinye yi yinjini okhethekileyo. Ulwazi irekhodwa kwi diski ngokohlobo pulses ezimfutshane zombane echaphazela kumphezulu wazo ferromagnetic.

Ngoko ke wazalwa amasuntswana - iyunithi incinane yomlinganiselo. Nokuqhubeka ukuvula umbuzo wokuba yintoni kilobytes, kodwa ayikwazi kuthintelwe nto.

Le yunithi basic - byte

Endle ziikhowudi computer yeyona iyunithi incinane esisiseko inkcazelo yedijithali. Lukamongameli ikhowudi yokubini kwaye ingathatha amaxabiso ezimbini kuphela: 0 no 1. I ilandelayo - bytes - sele iyunithi ulwazi eyakhiwa ziikhowudi 8, kwaye isoloko iphindaphindeke 2. Kwezinye iimeko, le ibhloko ubizwa ngokuba octet. ukuqonda kule, umntu ukuba byte lwedatha eli candelo lincinane.

Kodwa yintoni na Kbytes? Ulwazi kwi computer yakho igcinwe zibe ngumqulu ezahlukeneyo, kwaye kutshanje ngakumbi kubungakanani iifayili isiba ngakumbi nangakumbi. Thatha nkqu memory: Ukuba ngaphambili ukuba kwakunokwenzeka ukuba makenze gigabytes-2, ke ngoku 4 kancinane. Ngoko ke, ukuqaliswa iiyunithi ezivela ixabiso usisiseko wasiwa zokulinganisela eendaba enkulu ubukhulu. Okt kilobytes - lithatyathwe ukusuka kwisiseko - bytes. Nokuba zingaphi ibhithi ikhilobhayithi nganye - impendulo yalo mbuzo ngezantsi.

yezabelo

Njengoko sele kukhankanyiwe ngentla apha, iiyunithi eyenziwe athathiweyo kuthetha ukunciphisa inani labantu ngokubanzi. Igcwele nje kuphela kwinkalo yokwazisa. Ukulinganisa ubude-manzi esetyenzisiweyo kunye nezakhi zayo - ikhilomitha nanometer kunye nabanye. Ahlobene benziwa ngokudibanisa byte "Kilo" attachments, "musa", "Giga" kunye nabanye.

Igama elisetyenziswa yokuqala byte Werner Buchholz ngo-1956. Njengoko kukhankanyiwe, lo byte-8-bit ubizwa ngokuba octet (Octet). Kukho 4-bit, ekuthiwa imvubu (imvubu). Ukusebenzisa i console sinwenwile ukususela ka1789. Le yokuqala yaba isimaphambili 'Kilo "yaye" mega ".

Kucacile ukuba, ngelo xesha iikhompyutha baqala kuphela ukuba zikhona, kwaye isixa idatha ezincinane elalibalwa ezi yezabelo. Nangona kunjalo, kwisiqingatha sesibini senkulungwane XX kwakukho isimaphambili "Giga" omtsha, "Tera", kunye nabanye. Yaye ndicinga kuphela zingaphi kilobytes ziqulathe - lukhulu!

Njengoko translate yezabelo

Ulwazi - lo nto singqongwe, oko sinako ukubona, ukuva nokufunda. Le computer kwakhona ufumana ulwazi, kodwa kuphela xa indlela yaso. Ukuza kuthi ga ngoku, it has esweni kunye nenkqubo iyunithi, abagcina nje hard disk. Qho ngonyaka-mali ka ulwazi ukwanda amaxesha amaninzi phezu, kunye nabasebenzisi eziqhelekileyo, ngendlela enye okanye omnye, senze imfuneko ukudlulisa okunye yiyunithi yomlinganiselo ukuya kwenye. Onke acacile, siya ukunciphisa yonke netafile, nto leyo ithiwe thaca apha ngasezantsi.

Ngoko ke, kubonakala ukuba 1 kB iqulethe 1024 bytes. Kunjalo nangezinye yezabelo. Oku kungancitshiswa kule fomu:

• 1 ikhilobhayithi = 1024 bytes;
• 1 imegabhayithi ikhilobhayithi = 1024;
• 1 GB = 1024 MB of;
• 1 ulinganiso lweenkcukacha ezinkulu = 1024 gigabytes;
• 1 PB = 1024 terabytes (njalo njalo).

badinga kuphela kilobytes iguqulelwe kancinane ngokwahlukileyo. Apha kuyimfuneko ukuqwalasela ukuba omnye byte ziikhowudi 8. Oku kwathiwa ngasentla. Ngokomzekelo, siye sibe ixabiso 128 amasuntswana, kunye nemfuneko zibek ibe bytes. Esebenzisa lo mthetho, inani ziikhowudi kwakufuneka ukohlula ngesi 8 Oko kukuthi, ngokwahlula 128 8, siye impendulo ngokulinganayo ku-16.

Ukususela theyibhile ingentla kuqondwe ukuba computer ukuba becala ifumana kwaye edlulisela zonke iinkcukacha ngolwimi lwabo, yaye oko kuyaqondakala kuphela kuye. Nje kwenzeka kwinzululwazi yekhompyutha kukho ngingqi njengoko kweenkqubo. iingcali zalo ukubhala iinkqubo ulwimi lwekhompyutha, kwaye kukulawula inkqubo yokubini. Nangona kweenkqubo isetyenziswa ngakumbi hexadecimal.

Ukususela kilobytes ukuba megabytes, njalo njalo

Kuyabonakala ukuba ezi amasuntswana kwi kilobytes ukuguqulela elula, kodwa kukho nezinye iimeko. Abanye abasebenzisi babhidanisa yezabelo ezifana megabytes, gigabytes kunye terabytes. Ikakhulu ezidlulileyo kwaba ngenxa yokuba iifayile ngoku baba enkulu. Noko ke, ukunqanda uphazamiseko, ungenza bakhokelwe theyibhile ingentla.

Enyanisweni, lonke ulwazi yedijithali iyilwe kwikhompyutha ngendlela ezahlukeneyo:

• amaxwebhu digital (namaxwebhu asemthethweni intanethi, iincwadi, iimagazini, njl);
• imifanekiso (imifanekiso, imifanekiso);
• umculo (kukho eninzi yeefomati MP3, WAV, WMA AAC FLAC, njl);
• videos (umboniso, imifanekiso eshukumayo, iividiyo ezimfutshane).

Kulo mzekelo, ngasinye kolwazi luphawulwa umthamo wayo kuxhomekeka kumgangatho. Ngokomzekelo, amaxwebhu elektroniki zidla ubukhulu lincinci amashumi eziliqela kilobytes. Kwezinye iimeko, kunokuba megabytes eziliqela ubukhulu. Le e-books, iimagazini (njani kilobytes ezininzi iqulethe imegabhayithi mnye, kakade).

Imifanekiso badla ukuthatha ezimbalwa ezilikhulu kilobytes of hard drive. Konke kuxhomekeke umlinganiselo inkalo, leyo, kwelinye icala, has inqwaba ntlobo.

Yona le vidiyo, ngoko ngokuqhelekileyo sithetha umthamo gigabytes aliqela kwaye kuxhomekeke ifomati. Movies ukulidla isithuba kakhulu, ingakumbi ukuba ibe yinxalenye olubonakalayo ezimibalabala. Ubukhulu unako ukufikelela gigabytes ukuya ku-40, 50 okanye ngaphezulu.

Izinga data

Ngokufuthi abasebenzisi isiphelo ezijongene afana kilobits, megabits (Mbit), kunye nabanye. Ngoko ke izinga data iboniswe kwi-intanethi. Amaxesha amaninzi, oko kulinganiswa kwi kbit / s okanye Mbit / s. Ukuba ukubonisa ubungakanani nayiphi na ifayile esetyenziswa bytes, isetyenziselwa sokulinganisa isantya kancinci, kwaye kukho imfuneko ukwazi kilobytes ezininzi kangakanani, umzekelo, 1 Mbit.

Ukuze wenze oku, uyakwazi ukuqhubeka evela kulandelayo:

• 1 kbit / s = 1000 amasuntswana okanye 10 ³ ngomzuzwana;
• 1 Mbit / umzuzwana = 1000000 okanye 10 ⁶ ibhithi ngomzuzwana.

Amaxabiso elinokuguqulelwa ukusuka megabytes Mbit ngokwahlula ngu 8. Leyo 1 Mbit / s kuya kuba 0,125 MB / s.

izixhobo translation

Kwimfuneko ukudlulisela iiyunithi ulwazi elektroniki ejongene nabani na ikhompyutha. Ukuze wenze oku, kukho iindidi ngeendidi iinkqubo. Abanye zikhululekile, ngoxa abanye kuya kufuneka ukuba uhlawule. Enoba oku, bavumela ukuba ngokulula ukwenza uguqulo unit omnye komnye.

Kwaye ke kufuneka ukuba uthwebula kwi khomputha yakho, ekubeni kukho converters ukuba enze le online. Nje uye resource efanelekileyo kwaye ngenisa ixabiso olifunayo, emva koko iya kubalwa. Ngaloo ndlela, kunokwenzeka ukuba ukusombulula umbuzo njani ukuguqulela kilobytes ye gigabytes, okanye megabytes.
