Amagama abizwayo nama-bytes ekuxhumaneni kwenethiwekhi kubhekisela kumayunithi ajwayelekile yedatha yedijithali edluliselwa phezu kokuxhumana kwenethiwekhi. Kukhona ama-bits angu-8 kuwo wonke ama-byte angu-1.
Isiqalo se "mega" ku-megabit (Mb) ne-megabyte (MB) kaningi indlela ekhethayo yokuveza amazinga wokudluliswa kwedatha ngoba isebenzelana kakhulu ngama-bits kanye ne-bytes ezinkulungwaneni. Isibonelo, inethiwekhi yakho yasendlini ingakwazi ukulandwa idatha ku-bytes yezigidi ezingu-1 njalo kwesibili, okubhaliwe ngokufanelekile njengama-megabithi angu-8 ngesigamu, noma yi-8 Mb / s.
Ezinye izilinganiso zikhiqiza izikweletu ezilinganisweni ezinkulu ezifana ne-1,073,741,824, okungukuthi zingaki izinsimbi eziku-gigabyte eyodwa (okungama-megabyte angu-1,024). Yini okungaphezu kwalokho ukuthi ama-terabytes, i-petabyte, nama-exabyte aphezulu kunama-megabytes!
Ukuthi ama-bits nama-bytes adalwe kanjani
Amakhompiyutha asebenzisa ama-bits ( afushane amadijithi kanambambili ) ukumelela ulwazi kwifomu ledijithali. I-computer bit iyinani elibanjwe kanambambili. Uma imelwa njengenombolo, izingcezu zingaba nenani elilodwa (elilodwa) noma eli-0 (zero).
Amakhomphyutha anamuhla akhiqiza izingcingo ezivela emiphakathini ephezulu ephansi kagesi esebenza ngamasektha edivaysi. Ama-adapter yenethiwekhi yekhompyutha aguqula le migomo ibe yiyo kanye nama-zero adingekayo ukuze adlulisele izingxenyana kunoma iyiphi isixhumanisi senethiwekhi, inqubo ngezinye izikhathi ebizwa ngokuthi ikhodididi .
Izindlela zokufaka ikhodi yomlayezo wenethiwekhi ziyahlukahluka kuye ngokuthi isiteshi sokudlulisa:
- Ukuxhumeka kwe- Ethernet kuthwala amabhutshi usebenzisa amasignali kagesi wezintambo ezihlukahlukene
- I-Wi-Fi ithatha izinkinobho ngokusebenzisa amasaka omsakazo wezimiso ezihlukahlukene
- Ukuxhumeka kwe-Fiber kusebentisa izimpande zokukhanya ukuphatha izinsimbi
I-byte imane nje ilandelana ngokulinganisa ubude bits. Amakhompiyutha anamuhla ahlela idatha kwi-byte ukuze ukwandise ukusebenza kahle kwedatha yemishini yenethiwekhi, ama-disks, kanye nenkumbulo.
Izibonelo zeBits kanye ne-Bytes ku-Computer Networking
Ngisho nabasebenzisi abangajwayelekile abasebenzisi bamakhompiyutha ekhompiyutha bazohlangana nezinkinobho kanye nama-bytes ezimweni ezivamile. Cabangela lezi zibonelo.
Amakheli e-IP ku-Intanethi ye-Inthanethi Protocol 4 (IPv4) inethiwekhi iqukethe ama-32 bits (4 byte). Ikheli 192.168.0.1 , isibonelo, linamanani angu-192, 168, 0 no-1 ngayinye yezintatheli zalo. Ama-bits nama-bytes alowo kheli afakwe ikhodi njengalokhu:
11000000 10101000 00000000 00000001Isilinganiso lapho idatha ihamba khona ngokusebenzisa uxhumano lwenethiwekhi yekhompyutha ngokuvamile kulinganiswa ngamayunithi wezinkinobho ngomzuzwana (bps). Amanethiwekhi wamanje akwazi ukudlulisela izigidi noma izigidi zezibhakithi ngomzuzwana , okuthiwa ama- megabits ngomzuzwana (Mbps) nama- gigabits ngesigamu (Gbps) , ngokulandelana.
- Ukuxhumeka kwe-Gigabit Ethernet kulinganiswa nge-1 Gbps
- Ama-router okungaxhunyiwe angenazintambo anikeza ukulinganisa kwejubane lokuxhumeka okuhlukile ngokuya ngesimo se-Wi-Fi esetshenzisiwe. Amazinga avamile asekelwe ama-routers afaka 54 Mbps, 150 Mbps, kanye no-600 Mbps
Ngakho-ke, uma ulanda ifayela le-10 MB (80 Mb) kwinethiwekhi engalanda idatha ku-54 Mbps (6.75 MBs), ungasebenzisa ulwazi lokuguqulwa ngezansi ukuze uthole ukuthi ifayela lingalandwa esikhathini esingaphezu kwesibili (80/54 = 1.48 noma 10 / 6.75 = 1.48).
Ithiphu: Ungabona ukuthi inethiwekhi yakho ingashesha kangakanani ukulanda futhi ilayishe idatha nge- intanethi yokuhlola isayithi .
Ngokuphambene nalokho, amadivaysi okugcina amakhompyutha afana nezinduku ze- USB kanye ne- drives kanzima ukudlulisa idatha kumayunithi ka-bytes ngomzuzwana (Bps). Kulula ukudidanisa lezi ezimbili kodwa ama-bytes ngomzuzwana yi-Bps, ene-capital "B," ngenkathi amabhuzu ngesigamu isebenzisa i-lowercase "b."
Izinkinobho zokuphepha ezingenantambo ezifana nalezo zeWPA2, i-WPA, ne-WEP endala zilandelana ngezinhlamvu nezinombolo ngokuvamile ezibhalwa ku-notation hexadecimal . Ukubalwa kwenombolo ye-hexadecimal kubonisa iqembu ngalinye lezinkinobho ezine njengenani elilodwa, noma inombolo phakathi kwe-zero nesishiyagalolunye, noma incwadi phakathi kwe- "A" ne "F."
Izinkinobho ze-WPA zibukeka kanje:
12345678 9ABCDEF1 23456789 ABAmakheli enethiwekhi we-IPv6 futhi avame ukusebenzisa inombolo ye-hexadecimal. Ikheli ngalinye le-IPv6 liqukethe ama-128 bits (16 bytes), afana:
0: 0: 0: 0: 0: FFFF: C0A8: 0101Indlela yokuguqula ama-Bits nama-Bytes
Kulula kakhulu ukuguqula ngamanani amancane namanani we-byte uma wazi okulandelayo:
- 8 ama-bits = 1 byte
- I-1,024 bytes = 1 kilobyte
- 1,024 kilobytes = 1 i-megabyte
- Ama-megabytes angu-1,024 = i-gigabyte engu-1
- Ama-gigabytes angu-1,024 = 1 i-terabyte
Isibonelo, ukuguqula ama-kilobytes angu-5 zibe yizinkinobho, ungasebenzisa ukuguqulwa kwesibili ukuthola ama-byte angu-5,120 (1,024 X 5) bese owokuqala uthole amabhethri angu-40 960 (5,120 X 8).
Indlela elula kakhulu yokuthola lokhu kuguqulwa ukusebenzisa i-calculator njenge-Bit Calculator. Ungabuye futhi ulinganise amanani ngokufaka umbuzo ku-Google.
