Pehea e unuhi nāʻai i loko o megabytes a me ka hope?

I kēia lā mākou ola mea paakiki e noonoo ai i na ole kamepiula 'ē aʻe. Ka mea i loaʻa mai'ō a'ō. Ka hua'ōlelo "iki", "ʻai", ua lilo "megabytes" hapa o ko kakou mau ola. Ano o kanaka pinepine hana ia me ka mea a lakou e hanaʻi pela, me ka ike, a pehea e hai aku i kekahi i kekahi.

'āpana, kilobits ...

Aia mea he Honua Nei kahiko. He aha ka i ka likeʻole o ka maʻamau kanaka, a me ka kamepiula hoʻomalu? Ka muaʻoiaʻiʻo i kekahi kilobyte 1000 nāʻai, a me ka lua o ka - ma ka kilogram - 1024 nā huna. A me ka maʻamau kanaka pinepine noi, a me ka mea, ma ka mea, he'ōlelo hoʻomakeʻaka. Ua pono, ua, e ike i kahi nolaila wawae ulu, a loaʻa mai ana, e unuhi i ka nāʻai i loko o megabytes a me nā mau huahelu.

Iki - ka uuku pa alima o aeaie 'ike. More kaʻoi loa, kona mea. He pili i ka ike e pili ana i kekahi o na Hawaiiʻelua o ke kiʻi. No ka laʻana, he hoailona / i hōʻailona, oiaio / wahahee, 1/0, a no laila, ma luna o. G. Mai ka 'ōlelo Pelekānia inoa mākaukau kaua paha ma ka ho'ēmiʻanaʻelua nary digi k ( "aeaie") = pihoihoi. A "iki" pili i kekahi huahelu o ka aeaie kivila. Ma keia hihia, he kekimala huahelu ua poe like me ka 'Aʻohe paha kekahi, no ka laʻana i hōʻike i loko o ka papaʻaina. Keia ua kapaʻia he "aeaie nenoaiu o numeration."

I hiki ke ike, i ka helu 0 a me 1 i ka ia e hoohalike ai, a kekimala deuce i mau'āpana - 10. A i loko o ka ewalu - (1000)ʻehā.

A me ka aha mea kilobits?

Ka loa he ākea hana o keia helu'ōnaehana i loaʻa ma ka 'enehana kamepiula. Ma 'ana, ka aeaie helu i hoʻohana i ka helu o kikohoʻe Memories.

Eia he laʻana. I ka helu a hiki i ka helu kuhi henua ma ka aae? Oeia mea like me kekahi helu o ka elua i loko o kekahi nui N. A i ole ia - 2 ^N. Here, N Kû ka helu o nā'āpana o ke kaʻa'ōhua. He aha e mākouʻike? I ka helu ana o aeee i loko o ka iaiyoe? Inoaia mea like i kekahi a me kekahi degere o 2. A laila, - i oi hana hoihoi. Helu 2 ¹⁰ = 1024 mea kokoke loa i ka 1000. I ka Ia manawa, na tausani o ia i ke kumu no ka kekimala prefixes. No laila, i kapaʻia 1024'āpana "kilobits". By analogy me ka nā kilo gram a me nā kilo mika. Au i keia iloko o ka Honua Nei, i hoikeia ma luna.

Nāʻai a me nā'āpana

O ke kamepiula 'epekema i kapa ia penei. "Nāʻai" (Eng.ʻai) ua kapaia ka papaa noiʻi, a me ka aaioee o kikohoʻe 'ike. Ua ho i ka helu o nā'āpana ka poʻe hoʻokō 'kamepiula. O ka Classic.

Hoikehonua, kamepiula nenoai hanaʻai oia hoi o 8'āpana. No, ka mea, e lawe 256 (2 ⁸⁾ kekahi mau loina.

E hoohuli nāʻai i megabytes, e hana. Makemakika no ka mea kolu o ka papa. 1 kilobyte = 1024 nāʻai. E hoʻomanaʻo e pili ana i Pepeluali ^10? A 1 MB = 1024 KB (m. E. 2 ^{@ 20} = ^2x10 2) = 1048576 nāʻai.

noi

Loa pinepine, na nāʻai hoʻohana ma ka kamepiula nenoai, a me nā'āpana - ma ka aeaiiuo EYI latike. Nui, no ka māmā holo ana.

Eia he laʻana. Ethernet aʻeo ka hoʻolele 'hoʻolako i kaʻikepili ana i loko o ka laulā o ka 10 Mbit / mau i 1 GB / s. More E e kaulana e, like me ka rula, nāʻai denoted ma ka palapala "B" (a Lakina «B»). "Nahu mai la" a me ka hoʻopaʻa '. Ka pākuʻina kau "nā kilo" Ua hōʻikeʻia e "K" letter. He He poʻo, aole i ka lowercase. A liʻiliʻi "K" Ua palapala i ka inoa o ka kekimala pākuʻina kau "nā kilo", oa March ¹⁰ = 1000. ¶ noonoo i oi au mamuli o ka kēia mau nīnau.

Aeaie a kekimala prefixes

Pehea e unuhi nāʻai i loko o megabytes, oi a emi kālaʻe. I kakahiaka nui 1999, i ka luawai-ike hui IEC (International Electrotechnical Komisina) i loko o holo aeaie pākuʻina kau e lilo mau huahelu o ka nui o ka 'ike. Ke kumu no keia i na huahelu koke 1024 a me 1000. like me,ʻike mau kekimala prefixes hoʻohana i ka Si'ōnaehana, aeaie OAOOUIEeE wale ma ke kūapoʻana i ka hope syllable i loko o "ʻelua" (mai Roma binarius - aeaie). Ua nana i hoike ma ka papaʻaina ma lalo nei.

Ka hae aponoia ma nā mea he nui, akā, e hoʻohana emi pinepine ke komo inoa,ʻano nui i loko o ke kākau 'ana a me ka hōʻike waha' - aneane loa. Pehea e huli ma muli o i ka cacophony. Malia paha pela. Eʻae i kilobits kani nicer ma mua o kibibit a megabytes maikaʻi ma mua o mebibytes.

Unuhi nāʻai i loko o megabytes kālaʻe. Akā, i ka ole a pau. No laila, hiki, ma laila nō nā hoʻokokoke mai ai i ke kahua o kekahi mau 'Ikepili. I ka ninau, a hiki aku i hookahuli ai i ka nani nui mau i loko o ka 1ʻai pāmiliona o nāʻai.

Ka mua kokoke

.. Ma ka mea, i ka pākuʻina kau "nā kilo," "mega," a pela aku e hoʻohana i ka aeaie no ka mea kēia hihia.

• Ke AEI manakia a me nā lako polokalamu ma ka abbreviated waihona nui okoʻa no ka manawa. No ka laʻana, ka papahana mau moʻolelo i ka mooolelo nui o 10 MB. Ke Classic ala e hoolilo nāʻai i loko o megabytes, noonoo i ka nui o ka i mea like me 10485760 nāʻai. Ke AEI man- akia o nā Aey? Acaeoey me ka maʻamau dimensioning - ka hoʻohana 'ana i ka abbreviated ano o aeaie prefixes, ka MiB (MiB).

Ka lua o ka hele

Eia na hooluolu mai i hoʻohana like me ka kekimala i loko o ka kēia hihia.

• Hard a me ka'ōnohi kipaku aku ai. Lākou ka leo alakai ma kekimala megabytes. Ka hoʻokoe ': CD, kona nona iho ua hōʻike ma aeaie.
• Ka hoʻomaʻamaʻa kamaʻilio. Ma kēia hihia, na loina o kaʻoʻoleʻa ua hoʻokōʻia. No ka laʻana, ka buke o ma kahi o 10 miliona nāʻai o ka waihona hiki e mai la oia ia ia "kaupaona" 10 megabytes. Aha kakou e ike nei iʻaneʻi? Ma keia hihia, ke nāʻai i loko o megabytes hoololiia mea,ʻaʻole loa pololei, akā, kamailio ua lalau wahi.
• Inoa o ke kelekaʻaʻike pili holo. No ka laʻana, lawe i ka 100BASE-TX hae. Ma ia 100 Mbit / sʻikepili kōmi hoʻopili like me kēia nui 100 miliona'āpana / mau. E ka nana aku i kekahi "nimble" hui hou me ka 10 Gbit / mau (10GBASE-X hae). Ua hoʻopili like me kēia nui 10 ieeeea?'āpana / mau. Ia ka leo o ia. A i ka iki oi a emi.

Akā, me he ekolu-'īniha floppy nā pā 1,44 MB (hoomanao mau?) He e oi hana hoihoi. I kā lākou kākoʻo ua hōʻike ma ka aeaie-kivila mai kekimala megabytes. Ua hoomakaukau Ua like penei. One ia "megabytes" ua Kiba ka 1000, i mea o ka hola 0,977 MiB, akā, i ka mea ia manawa 1 Kiba e loaa 1024 nāʻai.

It E e kaulana ia aia no he okoa ma waena o kēia mau koho hoolohe hooluolu mai. Oiai ma ka hihia kilobytes ka mea, aole e oi aku mamua o 2.4%, alaila, no kaʻai pāmiliona mea mua 4,9% ia GB - 7,4%, a no ka terabyte -ʻaneʻane 10%. O ka hana ana,ʻaʻole i loko o ke aloha o ka aeaie e hoohalike ai. E. "Kakou" mākou Manufacturers nāʻai. No ka laʻana, kūʻai i ka paakiki a holo nona iho o 1 TB.
