Izvo zvinyorwa zvinyorwa uye zvinyorwa mumakombiyuta emakombiyuta zvinoreva zvidimbu zvakagadzirwa nedhidhiyo yedhiyabhorosi inotumirwa pamusoro pehutano hwehutano Pane 8 bits for each 1 byte.
Izwi rokuti "mega" mu megabit (Mb) uye megabyte (MB) inowanzova nzira yakanakisisa yokuratidza kutengesa kwedhidha nekuti inonyanya kuita nemabhandi uye nemaoko muzviuru. Semuenzaniso, imba yako yekutengesa inogona kukwanisa kudhonza dhiyabhorosi pa1 mamiriyoni bytes yese yechipiri, iyo yakanyorwa zvakakodzera se8 megabits per second, kana kunyange 8 Mb / s.
Zvimwe zviyero zvinobereka bits kune hutano hunokosha sa1 077 741 824, iyo ndiyo yakawanda bits iri mune rimwe gigabyte (iyo inokwana 1,024 megabytes). Chii chinowedzera kuti iyo tababytes, petabyte, uye exabytes yakakura kudarika megabytes!
Maitiro uye Mavhinga Akasikwa
Makombiyuta anoshandisa bits (pfupi nokuda kwebhinari majeri ) kuti amiririre mashoko muchimiro chechidimbu. Kakombiyuta bit is value binary. Kana inomiririrwa senhamba, bits inogona kukosha ye 1 (imwe) kana 0 (zero).
Makombiyuta emazuva ano anokonzera bits kubva kumakwikwi epamusoro uye ezasi emagetsi anowedzera kuburikidza nemakwikwi emagetsi. Kakombiyuta network adapters inoshandura matanho aya mukati mawo uye zeros inoda kugovana zvibvumirano kune imwe yenheji yekubatanidza, imwe nzira dzimwe nguva inonzi encoding .
Nzira dzekushandura mashoko emakodhi dzinosiyana siyana zvichienderana nehurukuro yekufambisa:
- Ethernet matanho anotakura bits achishandisa zviratidzo zvemagetsi zvekusiyana siyana
- Wi-Fi inotakura bits uchishandisa zviratidzo zveredhiyo zvakasiyana-siyana
- Fiber connections inoshandisa mapurisa emwenje kutakura bits
A byte is just a fixed-length sequence of bits. Makombiyuta emazuva ano anoronga dhidhii mumatope kuti awedzere kufambiswa kwedhiyabhorosi inobudirira yemichina yekushandisa, diski, nekuyeuka.
Mienzaniso yeBits uye mabhii muComputer Networking
Kunyange vanhu vasingashamisi vemakombiyuta emagetsi vachasangana nezvibvumirano uye zvinyorwa mumamiriro ezvinhu chaiwo. Chimbofunga mienzaniso iyi.
IP mazita muInternet Protocol version 4 (IPv4) networking ine 32 bits (4 bytes). Kero 192.168.0.1 , somuenzaniso, ine mazano 192, 168, 0 uye 1 yega yega yega. Izvo zvinyorwa uye mabheti etaiti iyoyo zvakanyorwa saizvozvi:
11000000 10101000 00000000 00000001Mutengo iyo data inofamba kuburikidza nekombiyuta yekubatanidza mitambo inowanzoyerwa muyuniti yezvidimbu kwechipiri (bps). Mazuva ano mitambo inokwanisa kutumira mamiriyoni kana mabhiriyoni emabhesi pamusi wechipiri , anonzi megabits pamushure (Mbps) uye gigabits kwechipiri (Gbps) , maererano.
- Gigabit Ethernet connections inotaridzirwa 1 Gbps
- Nzira dzisingabatsiri dzomugabhanji dzinopa hutano hwakasiyana-siyana hunoenderana nemhando ye Wi-Fi inoshandiswa. Zvose zvinowirirwa zvinotsigirwa neharairi dzinosanganisira 54 Mbps, 150 Mbps, uye 600 Mbps
Saka, kana iwe uri kukanda 10 MB (80 Mb) faira pane network inogona kukopa data pa 54 Mbps (6.75 MBs), unogona kushandisa mashoko ekushandura pasi apa kuti uwane kuti faira inogona kubudiswa mukati memakore maviri chete (80/54 = 1.48 kana 10 / 6.75 = 1.48).
Zano: Unogona kuona kuti nokukurumidza network yako inogona kudhandira sei uye kuisa dheinesi ne internet inowedzera test site .
Kusiyana neizvi, zvigadziridzo zvekuchengetedza makombiyuta sematanda e USB uye zvinotyisa zvinotumira dhamusi muzvikamu zve bytes kwechipiri (Bps). Zviri nyore kuvhiringidza maviri asi masikati pamusi wechipiri Bps, ane "B," apo bits pamusi wechipiri anoshandisa pasi "b."
Nhepfenyuro dzisingasviki dzekuchengetedza dzakafanana neaya dzeWPA2, WPA, uye yekare yeWEP yakaenzanirana netsamba uye nhamba dzinowanzonyorwa muchiziviso che hexadecimal . Hexadecimal numbering inomiririra boka rimwe nerimwe rezvikamu zvina sehumwe huwandu, zvichida nhamba pakati pe zero nepfumbamwe, kana tsamba pakati pe "A" uye "F."
WPA zvitsva zvinoita seizvi:
12345678 9ABCDEF1 23456789 ABIPv6 network address zvakare inoshandisa hexadecimal numbering. Yese ye IPv6 kero ine 128 bits (16 bytes), yakafanana:
0: 0: 0: 0: 0: FFFF: C0A8: 0101Nzira Yokushandura Bits uye Zvinyorwa
Zviri nyore chaizvo kutenderera zvinyorwa uye zvinyorwa zvinokosha kana uchiziva zvinotevera:
- 8 bits = 1 byte
- 1,024 bytes = 1 kilobyte
- 1,024 kilobytes = 1 megabyte
- 1,024 megabytes = 1 gigabyte
- 1,024 gigabytes = 1 terabyte
Semuenzaniso, kuti uchinje ma kilobytes mashanu muzvidimbu, unoshandisa yechipiri kutendeuka kuti uwane 5,120 byte (1,024 X 5) uye ipapo wokutanga kuwana mabheji 40 960 (5,120 X 8).
Nzira yakareruka yekutora uku kutendeuka ndeye kushandisa kadhiyuta seBit Calculator. Iwe unogonawo kuverenga maitiro kuburikidza nekupinda mubvunzo muGoogle.
