Pang'ono - gulu la nkhani

Pang'ono - ndi muyeso kuchuluka kwa mfundo. Klod Shennon akufuna kugwiritsa ntchito pokha akuti mu 1948 amatanthauza gulu la nkhani. Tsopano tikambirana za mbiri ndi ochititsa zosiyana mwatsatanetsatane.

Ndichiyani

Ngati ife kulankhula za mmene ntchito yomasulira mawu "pang'ono", chomwe ndi lingaliro ili, nanga chiyambi chake, tiyenera kunena kuti English mawu bayinare manambala, amene anayambitsa akuti amachokera English kutanthauza nambala bayinare. Komanso pali muli zina mawu masewera. Pang'ono - chidutswa kapena tinthu.

Ngati timaona kuti chidutswa chimodzi mu kachidindo bayinare akhoza kutenga mfundo ziwiri zokha, zomwe ndi matanthauzo ofananafanana: inde / ayi, 1/0 timapeza tanthauzo lina. Choncho, pang'ono - chiwerengero cha zomwe zimathandiza kuti ayankhe bwino anafunsa dongosolo. Mu zamagetsi, chidutswa chimodzi limafanana chimodzi bayinare pepala-kulephera amene ali limati awiri khola.

mitundu

Choncho, tinganene kuti chidutswa chimodzi - unit wofanana ndi manambala umodzi mu bayinare dongosolo chiwerengero. 2 mwinanso kukhazikitsa umodzi bayinare manambala. Alternating Pang'ono zimaphatikizapo kugwiritsa ntchito linanena bungwe lina la latch bayinare, mmene mlingo ziro zikhoza kutanthauza mbendera "0", ndi vuto dera zotheka.

Ndiyeno mkulu mlingo ndi udindo mbendera "1" ndi Kutukula zonse za dera la. Akamva Biphase kumafuna ntchito zonse bayinare latch zotuluka. Mu nkhani ya ntchito yoyang'anira dera wina wa m'njira ziwiri okwezeka, wachiwiri - Low. Tikumbukenso kuti mkulu mlingo kwa ochititsa onse, ndi otsika kwa mawaya onse amasonyeza vuto dera.

ukuthamana

Ngati ife kulankhula za sayansi computer, komanso Intaneti ya HIV deta, pali zambiri khalidwe ziro ndi wina anadutsa milingo yosiyanasiyana ya voteji kapena panopa. Tikumbukenso kuti m'munda wa makompyuta, makamaka pankhani mfundo ndi zolembedwa, mawu akuti "pang'ono" amagwiritsidwa ntchito mu lingaliro la "bayinare manambala". N'zochititsa chidwi kuti analogi wa Akamva kuti kompyuta kwadzidzidzi kukhala qubit (Q-Akamva).

mamvekedwe

Kuika deta mu kompyuta, wopangidwa mwa 8 Akamva, wotchedwa mamvekedwe. Kuti 8-bit chifaniziro maziko zilembo zina, mwachitsanzo kalata "A". Komanso, phindu izi zimathandiza kuti ntchito ndi masamu bayinare. M'mawu ena, ndi mamvekedwe ndi Tinthu lamulo item lolingana mu file yeniyeni.

Pankhaniyi, aliyense wa mamvekedwe ali ndi adiresi chapadera PC kukumbukira. Tinthu ndi mabayiti kuti analipo 0-7 ndipo amati ali kumanja kupita kumanzere. Mwachitsanzo, ngati tigwiritsa ntchito pang'ono chiwerengero 76543210, phindu lake ndi 01000001, ndi issuance wa chosindikizira mudziwe Ndondomekozi kupangidwa kalata mwachizolowezi "A".

Kuyenera anatsindika kuti chiwerengero cha Akamva m'gulu mamvekedwe limodzi ali wosamvetseka. Tikumbukenso kuti pamene timu akutembenukira kwa mamvekedwe, izo ndi macheke kompyuta munthu, ndipo ngati chiwerengero cha Akamva ngakhale m'gulu, dongosolo inati kulakwitsa. Koma zolakwa parity, zikhoza chifukwa cha kulephera hardware kapena kukhala chinthu chodabwitsa, koma izi zimachitika kawirikawiri.

Pamene processing deta mu kompyuta munthu mwa madera pakompyuta achuluka zikhumbo magetsi. madera amenewa zigwirizana ochititsa wapadera ndipo zipata mfundo, wotchedwa microdevices amagetsi. Pa zilakolako chomwecho chimene kudutsa zipata, wokhoza "chimatha". Ndiyamika deta izi kukonzedwa. Pomaliza, kamodzinso kukumbukira pang'ono - ndi koposa zonse, pang'ono ting'onoting'ono zambiri, zomwe ife kuphunzira pang'ono kwambiri.
