He aha te mea he PTM?

Ko te rorohiko Ko te matatini o te ngā whakaaro ngātahi ki te kōwae kotahi mā te pahi (whai hua mō ngā wāhanga ä-). Hei tauira, i tetahi o te rorohiko ngā mahara, PTM, whāurutau ataata, me pera atu. Ratou āhuatanga whakatau mahi whakamutunga whānui me āheinga. Ko tētahi o nga wae tino nui ko te wae tukatuka matua. I te tahi taime e taea kitea e koe tona ingoa atu: (. Eng Central Processing Unit - te wae taketake o te rorohiko) PTM, Ōrau, kohatu.

He aha te mea te PTM i ngā o te kaiwhakamahi toharite? Na roto i te faaauraa ki te tinana tangata hei rite ki te ōrau o te roro. mahi te reira i te Computations pāngarau katoa, a tetahi wahi whakarato he pāhekoheko i waenganui i te wāhanga. I te pae tino, te pūtukatuka ko te maramara nui tāutatia e te roto i te mokamoka motuhake o te kaupapa. Roto kei reira iahiko arorau matatini o te maha piriona transistors. Iwi paanga i roto i te pātai "he aha te mea te PTM», e taea noa te whakatau i te pūtukatuka ki ētahi atu wāhanga ā-. I muri i te katoa, ko reira tonu pūnaha tautauā kaha: totohu wera whakarewa nui, me te tahi. Ko te hiahia hoki ratou e tika ana ki te meka i te kohi o te maramara mana hiko ko maha tekau o Watts. Iti mata rōrahi haapurararaa me mata ki te mana nui whakawera PTM tinana e titau tautauā.

kaiwhakanao Pūtukatuka rerekē whakatau pātai whakawera: kotahi hoahoanga papaitia, hanga huarahi ki te mono poraka kāore, atu raro ngaohiko mana supply me te whakamahia ki te whakaputa i te whakatutukitanga hou ( "kikokore" tukanga hangarau), me ētahi atu wā, te matua "kaitākaro" i roto i te mākete o pūtukatuka pokapū. desktops me rorohiko e rua ngā kamupene - Intel me AMD. Nä, ko te toenga o te hanganga e whakaritea ki te āhuatanga o ratou hua.

E mea pinepine te pātai "he aha te mea te PTM» hoatu he tika ahuwhānui te whakautu. Ka taea te faataa tenei rawa noa: Na kua riro te wā "pūtukatuka" he tikanga whānui atu "wahi o te rorohiko." Na, i roto i tetahi waea pūkoro hou kua he kōwae e rave tātaitanga pāngarau - te hoki he pūtukatuka. Ahakoa rangatira o taonga tākaro a ngā tamariki te whakahaere he pai ki te mohio he aha te PTM, no te mea tapae ano hoki e ratou he wae tātai.

Oia mau, e kore te e whakaaro te parau tumu o te mahi o te pūtukatuka, ki matau nga āhuatanga whānui o taea tona mahi. hōtaka mana mahi PTM. He huinga o ngā tohutohu mo te pūtukatuka, tuhituhia i roto i tetahi reo papatono ratou. Naku korero, Whakatakotoria te hōtaka te tikanga tangohia. mahara te katoa ranei i te iti rawa i rongo o te reo papatono Basic. I roto i te reira, i roto i te tikanga ki te utu i te porohita i runga i te mata i hiahiatia ki te mahi i te Circle whakahau (taunga). te mau parau tumu Modern o te hōtaka tonu te taua: ko te mahi ki te waihanga i tētahi rōpū o ngā reo hōtaka. A, no te rere koe i te hōtaka i runga i te rorohiko tahuri te whakahau o te reo e whakamahia ana i roto i te waehere mīhini mō tukatuka tika i runga i te PTM he pūwetewaehere pūmanawa motuhake. Tenei waehere - ā-rua, tohu he raupapa o te hunga me ngā kore. e kore e taea e tokomaha matau reira he aha i whakaritea ki te whakamahi i te pūnaha ā-rua, nui atu i te mua te ira. I roto i te meka, faataa mea katoa te rawa noa: e taea ngāwari te paraire tuku whakahau ki nga transistors ratou. Hei tauira, mai e korero tatou e pā ana ki ngā pūrere mamati, ka taea e koe whakaaro i te tau "1" rite te aroaro o te ngaohiko i runga i te pūtake o te tetahi transistor, me te "0" - rite tona ngaro. Nä, i roto i te take tuatahi, ka uakina e te transistor te me haere nāianei roto ake, a i roto i te tuarua - kiia (o te akoranga, māmā katoa me ki te plurality o rahuitia).

Ko te tere o te mahi o nga tohutohu o te hōtaka whakatau te tere pūtukatuka. pāngia ana tēnei e te hoahoanga, te auau o te circuitry ā-o te mahi, mä te waehere.
