Pulogalamu ya Pulogalamu Yophatikiza Pakati (PCI) - yomwe imatchedwanso PCI yodalirika - ndizolemba zamakampani zomwe zinapangidwa mu 1992 zogwirizanitsa zipangizo zamakono zapakati pa kompyuta. PCI imatanthauzira zida zamagetsi ndi zizindikiro zamagetsi zomwe zimagwiritsidwa ntchito pa zipangizo kuti ziyankhulane pamabasi akuluakulu a kompyuta.
Ntchito za PCI pa kompyuta Networking
PCI inkagwiritsidwa ntchito mofanana ngati makompyuta a mabasi omwe amagwiritsa ntchito makhadi ophatikizira makhadi kuphatikizapo adapatsa Ethernet ndi Wi-Fi kwa PC. Ogulitsa angagule ma PC apamwamba ndi makadi awa asanakhazikitsidwe kapena kugula ndi kuzikwanira maka maka awo pokhapokha ngati pakufunikira.
Kuphatikizanso, pulogalamu yamakono ya PCI imaphatikizidwanso mu ma kompyuta apakompyuta. CardBus ndi PC Card (yomwe nthawi zina imatchedwa PCMCIA ) chinthu chothandizira kulumikiza khadi lochepa, la khadi la ngongole ngati adapita kunja kunja kwa basi ya PCI. Ma adapita a CardBus adatseguka m'malo otseguka amodzi kapena awiri omwe amakhala pambali pa kompyuta laputopu. Mapulogalamu a CardBus onse a Wi-Fi ndi Ethernet anali wamba mpaka mafakitale a hardware atasintha mokwanira kuti aphatikizidwe molunjika pamapope a ma lapulogalamu.
PCI inathandizanso makina apakitale apakati pa makompyuta apakompyuta pamtundu wa Mini PCI .
Mndandanda wa PCI unasinthidwa mu 2004 ku PCI version 3.0. Amakhala akuthandizidwa ndi PCI Express.
PCI Express (PCIe)
PCI Express imakhalabe yotchuka pa makompyuta lero ndi njira yatsopano yomwe ikuyenera kudzafalitsidwa m'tsogolomu. Zimapanga mawonekedwe apamwamba kwambiri a basi kuposa PCI ndipo amapanga magalimoto m'misewu yosiyana ya mayina yotchedwa mayendedwe. Zipangizo zimatha kukhazikitsidwa kuti zigwirizane ndi zosiyana siyana zomwe zimagwiritsidwa ntchito potsata njira zogwiritsira ntchito njira imodzi (x1, yotchedwa "ndi imodzi"), x4 ndi x8 kukhala yofala kwambiri.
- PCIe 1.0 (2002), 1.0a (2003) ndi 1.1 (2005) - pafupifupi 250 Mbps pa njira imodzi
- PCIe 2.0 (2007) ndi 2.1 (2009) - kawiri kawiri chiwerengero cha PCIe 1.x, pafupifupi 500 Mbps pa lane
- PCIe 3.0 (2010) ndi 3.1 (2014) - kawiri kawiri mlingo wa data wa PCIe 2.x, pafupifupi 1 Gbps pa lane
Ma PC adapotoza makina a PCI Express akuthandiza mibadwo yamakono ya Wi-Fi (onse 802.11n ndi 802.11ac ) amapangidwa ndi ojambula ambiri monga momwe zilili ndi Gigabit Ethernet . PCIyi imagwiritsidwanso ntchito ndi osungirako ndi mavidiyo adapala.
Nkhani ndi PCI ndi PCI Express Networking
Makhadi owonjezera angagwire ntchito kapena azichita mwanjira yosadziŵika ngati sakumangika (kukhala pansi) ku malo omwe ali PCI / PCIe. Pa makompyuta okhala ndi makadi angapo, ndizotheka kuti wina agwire ntchito yogwiritsira ntchito magetsi pomwe ena akupitiriza kugwira ntchito moyenera. Njira yowonongeka yomwe amagwira ntchito pogwiritsa ntchito makadiwa ndi kuyesa ma PCI / PCIe osiyanasiyana kuti afotokoze nkhani iliyonse.
Makhadi a PCI / PCI amatha kulephera chifukwa chowotcha (zomwe zimagwiritsidwa ntchito kwambiri ngati za CardBus) kapena chifukwa chokhala ndi mauthenga ogwiritsa ntchito magetsi pamtundu waukulu wa kuika ndi kuchotsa.
Makhadi a PCI / PCIe alibe zigawo zomangika ndipo akuyenera kuti m'malo mwake asinthidwe.
