Horumarka degdega ah ee kombuyuutarrada iyo tignoolajiyada isku xidhkooda (sidoo kale loo yaqaan "teknoolajiyada shabakada"), Ethernet waxay noqotay shabakad kombiyuutar laba lakab ah oo gaaban oo leh heerka ugu sarreeya ilaa hadda. Qaybta xudunta u ah Ethernet waa beddelka Ethernet. Buugga iyo...

VCSEL, oo ​​loo yaqaan 'Vertical Cavity Surface Emitting Laser' oo buuxa, waa nooc ka mid ah leysarka semiconductor. Hadda, VCSEL-yada intooda badani waxay ku salaysan yihiin gaAs semiconductors, iyo dhererka hirarka sii daaya inta badan waxay ku jiraan band mowjadaha infrared. Sannadkii 1977-kii, Professor Ika Kenichi oo ka tirsan Jaamacadda Teknolojiyadda ee Tokyo ayaa...

Shabakadda waxaa loo kala saari karaa LAN, LAN, MAN, iyo WAN. Macnaha gaarka ah ee magacyadan ayaa lagu sharraxay oo la barbardhigay hoos. (1) Shabakadda Aagga Shakhsi ahaaneed (PAN) Shabakado noocan oo kale ah waxay awood u siin karaan xidhiidhka masaafo-gaaban ee ka dhexeeya aaladaha macaamiisha la qaadan karo iyo aaladaha isgaarsiinta.

RSSI waa soo-gaabista Tilmaamaha Xoogga La Helay. Tilmaamaha xoogga calaamada ee la helay waxaa lagu xisaabiyaa isbarbardhigga laba qiime; taas oo ah, waxaa loo isticmaali karaa in lagu go'aamiyo sida ay u xoogan tahay ama u liidato xoogga calaamada marka la barbardhigo calaamad kale. Habka xisaabinta ee RSSI...

Laga soo bilaabo 802.11n, tignoolajiyada MIMO ayaa loo isticmaalay hab-maamuuska waxayna si weyn u wanaajisay heerka gudbinta wireless-ka. Gaar ahaan, sida loo gaaro horumarinta tignoolajiyada sare. Hadda aan si dhow u eegno tignoolajiyada MIMO. Iyada oo horumarka tignoolajiyada isgaarsiinta wireless-ka, mor...

Waxaa jira noocyo badan oo ah furayaasha suuqa, laakiin sidoo kale waxaa jira kala duwanaansho shaqo oo kala duwan, iyo sifooyinka ugu muhiimsan waa kala duwan yihiin. Waxa loo qaybin karaa iyadoo loo eegayo dareenka ballaadhan iyo cabbirka codsiga: 1) Marka hore, macno ballaadhan, furayaasha shabakadda waxa loo qaybin karaa laba qaybood...
