ʻO nā hua'ōlelo a me nā mākoki ma ka pūnaewele pūnaewele e pili ana i nā pūnaewele maʻamau o kaʻikepili helu i hoʻounaʻia ma luna o ka pūnaewele pūnaewele. Loaʻa 8 mau'āpana no kēlā me kēia kāneta.
ʻO ka prefix "mega" i ka megabit (Mb) me ka megabyte (MB) he mau ala maikaʻi loa ia e hōʻike ai i nā loli no kaʻikepili no ka mea e hana nuiʻia ana me nā piko a me nā bytes i nā tausani. Eia kekahi laʻana, hiki i kāu pūnaewele home ke hoʻouka i nāʻikepili i 1 million bytes i kēlā me kēia me kekona, kahi i kākau maikaʻiʻia i 8 megabits i kēlā me kēia lā, aiʻole 8 Mb / s.
ʻO kekahi mau mea e hāʻawi mai i nā hopena i nā koina nui e like me 1,073,741,824,ʻo ia ka nui o nā pahu i kahi hoʻokahi gigabyte (ʻo ia hoʻi 1,024 megabytes). He aha ka nui o nā terabytes, nā petabyte, a me nāʻeha iʻoi aku ka nui ma mua o nā megabytes!
Pehea i hanaʻia ai nā'āpana a me nā poʻi
Hoʻolākiʻia nāʻikepili (pōkole no nā hua liʻiliʻi ) e hōʻike i kaʻikepili ma keʻano maʻamau. ʻO kahi bitume pūnaewele he kumu waiwai. Ke paniʻia he helu, hiki i nā'āpana ke loaʻa ka helu o 1 (hoʻokahi) aiʻole 0 (zero).
Hoʻokumu nā'ōnaehana kūikawā i nā piko mai nā hāmole voltage kiʻekiʻe a me lalo e holo nei ma nā'ōpuni o ke kikowaena. Hiki i nā mea hoʻololi kikowaena ke hoʻololi i kēia mau lua pele i loko o nā mea a me nā zeros e pono ai ka laweʻana i nā pōʻai ma o ka pūnaewele pūnaewele, kahi hana i kapaʻia he kāpili i kekahi manawa.
Hoʻololi nāʻenehana o ka hoʻopā'ālua o ke kelepona me kaʻike i ke kauʻana:
- Hoʻokomo nā'eneka Ethernet i nā pōpiki me nā hōʻailona elemene o nā lua pele
- Hōʻikeʻo Wi-Fi i nā pahuhopu me ka hoʻohanaʻana i nā alapine loli o ke kelepona
- Hoʻohuiʻia nā kikowaena i nā pulses o ka mālamalama e lawe i nā pihi
ʻO ka lātelani he manawa lōʻihi o nā'āpana. Hoʻokumu nā'ōnaehana hou i nāʻikepili i loko o nā bytes e hoʻonui i ka maʻemaʻeʻikepili o nā mea kikowaena, nā disks, a me ka hoʻomanaʻo.
Nā lālā o nā Bits a me nā Bytes ma ka Pūnaewele
Hiki i nā mea hoʻohana maʻamau o nā kikowaena pūnaewele e paʻi i nā piko a me nā paka i nā manawa maʻamau. E noʻonoʻo i kēia mau hōʻailona
ʻO nā helu IP ma ka pūnaewele Protocol 4 (IPv4) pūnaewele aia he 32 mau bits (4 bytes). ʻO ka helu 192.168.0.1 , no ka laʻana, he waiwai ko 192, 168, 0, a me 1 no kēlā a me kēia o nā bytes. Ua hoʻopiliʻia nā'āpana a me nā bytes o kēlā address i like me:
11000000 10101000 00000000 00000001ʻO ke anapili i heleʻia e kaʻikepili ma o kaʻike pūnaewele pūnaewele i nā'āpana o nā bits ma kēlā me kēia (bps). Hiki i nāʻenehana hou ke hoʻokuʻu i nā miliona a iʻole nā piliona bits no kēlā me kēia lā , i kapaʻia he megabits ma kēlā me kēia (Mbps) a me gigabits i kēlā me kēia (Gbps) , ma muli o kēlā me kēia.
- Hoʻomākaukauʻia nā kuhi Gigabit Ethernet no 1 Gbps
- Hiki i nā mea'onike kelepona hikiʻole ke hāʻawi i nāʻikepili pili likeʻole e like me keʻano o ka Wi-Fi i hoʻohanaʻia. ʻO nā kuhi likeʻole i kākoʻoʻia e nā mea hōʻiliʻili he 54 Mbps, 150 Mbps, a me 600 Mbps
No laila, ināʻoe e hoʻouka i kahi faila 10 MB (80 Mb) ma kahi pūnaewele hiki ke hoʻouka i nā kikowaena i 54 Mbps (6.75 MBs), hiki iāʻoe ke hoʻohana i kaʻike hoʻohuliʻana ma lalo nei no kaʻikeʻana e hiki ke loli i kahi faila ma kahi oʻelua (80/54 = 1.48 aiʻole 10 / 6.75 = 1.48).
Kōkua: ʻikeʻoe i ka wikiwiki o kāu pūnaewele e loli a hoʻouka i nāʻikepili me kahi pūnaewele ho'āʻo wikiwiki pūnaewele .
I ka 'okoʻa, nā polokalamu kelepona polokalamu e like me nā kāpili USB a me nā kīkini koʻikoʻi e hoʻololi i nāʻikepili i nā kaʻina o bytes no kēlā me kēia (Bps). He mea maʻalahi ke hoʻololi i nā meaʻelua, akā he hapa wale no kaʻelua o Bps, me ka "B," ma ke kīpē.
ʻO nā kī pākuhi liʻiliʻi e like me ka WPA2, WPA, a me ka WEP kahiko ka pae o nā leka a me nā helu i kākauʻia i ka notation hexadecimal . ʻO ka helu helu Hexadecimal kēlā me kēlā me kēia hui o nā huʻukiʻehā ma keʻano hoʻokahi, a he helu paha ma waena o ka zero a me ka eiwa, aiʻole he leka ma waena o "A" a me "F."
E nānā nā kīʻai WPA penei:
12345678 9ABCDEF1 23456789 ABʻO nā inoa kikowaena IPv6 pū kekahi e hoʻohana i ka helu helu hexadecimal. ʻO kēlā me kēia helu IPv6 he 128 bits (16 bytes), e like me:
0: 0: 0: 0: 0: FFFF: C0A8: 0101Pehea e hoʻololi ai i nā Bits a me nā Bytes
He mea maʻalahi ke hoʻololi liʻiliʻi i nā waiwai bit a me nā byte i ka wā eʻike aiʻoe i kēia mau mea:
- 8 mau pahi = 1 byte
- 1,024 bytes = 1 kilobyte
- 1,024 kilobytes = 1 megabyte
- 1,024 megabytes = 1 gigabyte
- 1,024 gigabytes = 1ʻaoʻao
Eia kekahi laʻana, e hoʻohuli i 5 kilobytes i loko o nā piko, e hoʻohanaʻoe i ka hoʻololiʻelua e loaʻa 5,120 bytes (1,024 X 5) a laila i ka mua e loaʻa 40,960 bits (5,120 X 8).
ʻO kahi maʻalahi ka loaʻaʻana o kēia mau hoʻololiʻana,ʻo ia ke hoʻohana i ka heluhelu e like me ka Calculator Bit. Hiki iāʻoe ke hoʻomaopopo i nā koina ma ke komoʻana i ka nīnau i Google.
