Wireless nas - siv technologies thiab lawv nta

Ib tug ntev lub sij hawm thiab ua ib feem ntawm peb lub neej, tshiab technology. Yuav ua li cas nws twb mag ib tug txuj ci tseem ceeb niaj hnub no - txhua txhua hnub. Technology tsis sawv tseem, kev pab kiag li lawm khwb khuav evolve. Qhov no paub thiab seemingly yooj yim ntaus ntawv zoo li ib tug computer nas, dhau lawm, tau undergone tseem ceeb cov kev hloov. Tshwm nyob rau hauv thaum ntxov 60-ies ntawm lub xyoo pua xeem, qhov no zoo ntawm manipulators tau ua ntau yooj yim, ceev thiab ntau yog. Switched technology, uas yog siv nyob rau hauv lawv cov chaw ua hauj lwm. Niaj hnub no nws yog twb nyob rau hauv lub lag luam muaj ib tug loj ntau yam ntawm wireless nas, whereas ib tug ob peb xyoos dhau los txog qhov no thiab tsis txawm ua npau suav ntawm. Muaj ob peb hom ntawm lawv, thiab tsis txhob ua tsis ncaj ncees lawm kev xaiv, koj xav tau ib tug me ntsis me ntsis txog cov nta lawv, pros thiab cons.

Ib tug thoob plaws xaiv ntawm kho qhov muag thiab laser qauv. Kho qhov muag wireless nas yog ib tug me ntsis cheaper tshaj laser, tab sis qhov no zoo ntawm manipulators yog ua tsawg nrov - nws yog ib lub dhau theem. Kev siv cov laser tshuab tau tso cai rau ua cov kev taw qhia ntau yog, thiab tsiv mus nyob rau cursor hla qhov screen sai, lwm tus tshaj plaws yog tias siab speeds yog tsis tsim nyog, thiab txawm cuam tshuam nrog cov lag luam daim ntawv sau npe los yog graphics editors, tab sis qhov tseeb tseem - laser wireless nas yog ntau npaum li cas muaj tseeb thiab sai, tsawg nws yog xav tau nyob rau hauv lub chaw ua hauj lwm saum npoo av. Lub disadvantage ntawm no txoj kev yog qhov yuav tsum tau rau kis tau tus mob ntawm lub ntxias nyob rau hauv lub redistribution of-pom los ntawm cov receiver. Ib qho zoo heev piv txwv ntawm cov kev siv ntawm tej technology yog ib tug wireless nas A4Tech G7-200NX-1. Nws yog pheej yig, tab sis nyob rau tib lub sij hawm ib tug txhim khu kev qha daim ntawv.

Feem ntau cov qauv ntawm cov kis tau tus mob ntawm cov ntaub ntawv los ntawm lub wireless keypads yog txuas ntawm Bluetooth los yog xov tooj cua. Ob yam no txoj kev muaj ob zoo thiab disadvantages. Bluetooth yog feem ntau yog siv nyob rau hauv laptops - muaj ib tug built-nyob rau hauv module. Qhov no tsis txhais hais tias tus PC tsis tsim kom muaj xws li ib tug ntxias, tsuas yuav tau yuav ib tug coj qhov chaw nres nkoj. Qhov no kev twb kev txuas txoj kev kom ib tug high school cov kev ntseeg ntawm cov kev twb kev txuas nyob rau hauv lub pub ntau yam.

Txawm yog feem ntau desktop computers siv radiomyshki. Tej manipulators yuav tsum tau txuas lub USB adapter. Muaj lub xov tooj cua transmitters khiav hauj lwm rau ob frequencies: 2.4 GHz thiab 27 MHz. Dua zaus yog kim kim, tab sis muab ib tug ntau dua ntau yam. Txawm li cas los, suab nrov yuav cuam tshuam nrog - ntau pab kiag li lawm hauj lwm rau no zaus. Wireless nas nrog ib zaus ntawm 27 MHz imposes tej kev txwv rau cov kev sib txuas lus ntau yam, tab sis nyob rau hauv lub cheeb tsam ntawm lub receiver yog ruaj khov.

Niaj hnub no, peb tsim ib tug nas computer wireless, uas siv Wi-nkaus. Qhov no hom ntawm kis tau tus mob muab tus loj tshaj ntau yam - li network kev pab them nqi. Tab sis muaj ib tug drawback - ib txoj kev kis cov ntaub ntawv yog raug rau cuam.

Lub hwj chim muab tej zaum yuav muaj ib tug wireless nas hlwb los yog roj teeb. Tam sim no cov qauv yuav ua hauj lwm tawm nyob rau hauv ib tug txheej ntawm roj teeb 150 hnub nyob rau uninterrupted siv. Yog hais tias koj tsis xav kom peb los yog plaub zaug ib xyoos hloov lub roj teeb, yuav rechargeable roj teeb. Cia li xav tau lub sij hawm mus rau nqi lawv los ntawm lub sij hawm rau lub sij hawm.
