Numeri Zamatsenga mu Wopanda Pakompyuta ndi Pakompyuta

Ma kompyuta amagwiritsa ntchito matekinoloje ambiri omwe amawaphatikiza manambala. Zina mwa nambala izi (ndi magulu a nambala) zimakhala ndi tanthauzo lapadera. Kuphunzira kuti zonsezi "nambala zamatsenga" zikutanthawuza zingakuthandizeni bwanji kumvetsetsa malingaliro osiyanasiyana ndi mauthenga.

1, 6 ndi 11

Mapulogalamu opanda waya a Wi-Fi amagwira ntchito m'magulu omwe amachititsa maulendo. Mawonekedwe oyambirira a Wi-Fi amayendetsa njira zoyambira 1 mpaka 14 ndi zitsulo zina zokhala ndi magulu ophwanyika. Zipangizo 1, 6 ndi 11 ndizo zitatu zokha zomwe sizingagwirizane ndi njirayi. Osewera opanda makina osungira makompyuta kunyumba angagwiritse ntchito mwayi wamasewerawa pamene akukonzekera ma Wi-Fi awo ngati njira yochepetsera kusokonezeka kwa mbendera ndi anansi awo. Zambiri "

2.4 ndi 5

Ma Wi-Fi amagwiritsa ntchito makina awiri osayendetsa waya, pafupi ndi 2.4 GHz ndi ena pafupi ndi 5 GHz. Gulu la 2.4 GHz limathandizira njira 14 (monga tafotokozera pamwambapa) pamene gulu la 5 GHz likuthandiza ambiri. Ngakhale kuti ma Wi-Fi ambiri amathandiza mtundu umodzi kapena wina, zomwe zimatchedwa zipangizo zamagetsi zosagwiritsa ntchito makina awiri zimaphatikizapo mitundu yonse ya ma radio zomwe zimathandiza kuti chipangizo chimodzi chiyankhulire pamagulu awiriwo.

5-4-3-2-1

Ophunzira ndi akatswiri mwachizolowezi amaphunzitsa ulamuliro wa 5-4-3 wa makonzedwe ogwiritsira ntchito makina kuti awathandize kugwira ntchito ndi mfundo zamakono zamakono monga madera akumenyana ndi kufalitsa kuchedwa. Zambiri "

10 (ndi 100 ndi 1000)

Mapulogalamu apamwamba a deta a Ethernet ndi ma megabits 10 pamphindi (Mbps). Pamene chitukukochi chapakati pa zaka za m'ma 1990 ndi 2000, mautumiki a Fast Ethernet omwe amagwiritsa ntchito ma Mbps 100 anakhala ofanana kwambiri, otsatiridwa ndi Gigabit Ethernet pa 1000 Mbps. Zambiri "

11 (ndi 54)

Kuwerengera kwapadera kwa deta yamakono oyambirira a nyumba ya Wi-Fi kuyambira 802.11b anali 11 Mbps. Zotsatira za 802.11g zowonjezera Wi-Fi zinawonjezeka pamtunda wa 54 Mbps. Masiku ano, kuthamanga kwa Wi-Fi kwa 150 Mbps ndipamwamba ndi kotheka. Zambiri "

13

Dongosolo la Name Domain (DNS) limayang'anira mayina a mayina a intaneti padziko lonse lapansi. Kuti ufike pamsinkhu umenewo, DNS imagwiritsa ntchito mndandanda wambiri wa ma seva. Muzu wa ulamulirowu ukukhala pa 13 DNS root server masango omwe amatchedwa 'A' kupyolera mwa 'M.' Zambiri "

80 (ndi 8080)

Mukutumiza kwa TCP / IP , mapeto omveka a mauthenga oyankhulana amayang'aniridwa kudzera mu dongosolo la manambala a phukusi . 80 ndi nambala yovomerezeka yogwiritsidwa ntchito ndi ma seva a pawebusaiti kuti mulandire zopempha za HTTP zomwe zikubwera kuchokera kwa osatsegula pa Webusaiti ndi makasitomala ena. Maofesi ena omwe amagwiritsa ntchito Webusaiti monga ma laboratory test labbs amagwiritsanso ntchito port 8080 pamsonkhanowu monga njira zopitirira 80 kuti asagwiritse ntchito malamulo oletsa kugwiritsa ntchito ma doko otsika ochepa pa Linux / Unix. Zambiri "

127.0.0.1

Zokonzetsa zamagetsi pamsonkhano zimagwiritsa ntchito adilesi ya IP ya "loopback" - njira yapadera yolankhulira yomwe imalola chipangizo kutumiza mauthenga paokha. Akatswiri amagwiritsa ntchito njirayi kuti athandize zipangizo zamagetsi ndi mapulogalamu. Zambiri "

192.168.1.1

Adilesiyi yapadera ya IP inadziwika m'mabanja ndi maulendo akuluakulu apanyumba ochokera ku Linksys ndi opanga ena omwe adasankha (kuchokera pakati pa chiwerengero chachikulu cha zida) ngati fakitale yosasintha kwa woyang'anira akulowa. Maulendo ena otchuka a adter IP amphatikizapo 192.168.0.1 ndi 192.168.2.1 . Zambiri "

255 (ndi FF)

Chiwonetsero chimodzi chokha cha deta yamakompyuta chingasunge mpaka 256 malingaliro osiyana. Pogwiritsa ntchito makompyuta, makompyuta amagwiritsira ntchito manambala kuti awonetse chiwerengero pakati pa 0 ndi 255. Pulogalamu ya IP yobwereza ikutsatira msonkhano womwewo, pogwiritsa ntchito manambala ngati 255.255.255.0 monga masks a network. Mu IPv6 , mawonekedwe a hexadecimal 255 - FF - ndilo gawo lakulumikiza kwake. Zambiri "

500

Mauthenga ena olakwika omwe asonyezedwa pa osatsegula pa Webusaiti amalembedwa ndi ma code olakwika a HTTP . Zina mwazimenezi, HTTP zolakwika 404 ndizodziwika bwino, koma izo zimayambitsidwa ndi mavuto a pawebusaiti m'malo mogwirizanitsa. HTTP 500 ndi machitidwe olakwika omwe amawonekera pamene seva la intaneti silingathe kuyankha pempho kuchokera kwa kasitomala, ngakhale kuti zolakwika 502 ndi 503 zingathe kuchitika pazinthu zina. Zambiri "

802.11

Institute of Electrical and Electronics Engineers (IEEE) imayang'anira banja la ma intaneti opanda waya pansi pa chiwerengero cha "802.11." Malamulo oyambirira a Wi-Fi 802.11a ndi 802.11b adavomerezedwa mu 1999, atsatiridwa ndi Mabaibulo atsopano kuphatikizapo 802.11g, 802.11n ndi 802.11ac . Zambiri "

49152 (mpaka 65535)

Nambala za phukusi za TCP ndi UDP kuyambira 49152 amatchedwa madoko akuluakulu , madoko apadera kapena madoko ophatikizira . Maiko amphamvu samayang'aniridwa ndi bungwe lolamulira lirilonse lofanana ndi IANA ndipo alibe zopinga zapadera zogwiritsira ntchito. Mapulogalamu amatha kugwira chimodzi kapena zingapo zopanda maofesi amtunduwu pamtundu umenewu pamene akufunika kupanga mauthenga a zitsulo zamtundu wa multithreaded.
