Yazi ukuthi i-Laptops Features ingawuthola kanjani ku-intanethi
Ukukwazi ukuxhuma kwi-intanethi kungakhathaliseki ukuthi ukhona yini isici esibalulekile se-laptops. Ngenxa yalokho, ukuxhumeka kwenethiwekhi kunesidingo kuzo zonke i-laptops. Ezinye zazo zivame kakhulu ukuthi ukuqhathanisa imikhiqizo kunzima kodwa kungase kube nokuhluka okuncane okungenza umehluko ekusebenzeni kwenethiwekhi. Lo mhlahlandlela uzokusiza ukuhlonza ukuthi yiziphi nokuthi ziqhathaniswa kanjani.
I-Wi-Fi (engenantambo)
Ukuxhumana okungenazintambo ngezindinganiso ze-Wi-Fi sekuqhume iminyaka eminingi ukwenza isici esidingekayo kuwo wonke amakhompyutha we-laptop. Kunezinhlobo eziningi zama-acronyms wezindinganiso ezihlukahlukene kanye nokuvinjelwa kwezinethiwekhi zokuxhumana ze-Wi-Fi ozodinga lapho uzothenga ikhompyutha yekhompuyutha ukuze ukwazi ukuthi zingasetshenziswa kanjani.
Kukhona okwamanje amazinga we-Wi-Fi amahlanu angatholakala kumakhompyutha we-laptop. I-802.11b yiyona endala kunazo zonke ezisebenza ku-11Mbps kumsakazo we-2.4GHz womsakazo. I-802.11g isebenzisa i-2.4GHz yemisakazo efanayo kodwa ingadlulisela ku-54Mbps ngesivinini. Ibuyela emuva iyahambisana ne-802.11b standard. I-802.11a isebenzisa i-spectrum ye-5GHz yomsakazo wezinga eliphezulu futhi okufanayo okusheshayo kwe-54Mbps. Awubuyiselwa emuva emuva ngenxa yama frequency omsakazo ahlukene asetshenzisiwe.
Inguqulo evamile ejwayelekile ye-Wi-Fi iyinqubo ejwayelekile ye-802.11n. Le nqubo idideka kakhulu njengoba idivaysi ingasetshenziswa ukusebenzisa i-spectrum ye 2.4GHz noma i-5GHz. Indlela eyinhloko yokutshela ukuthi i-laptop ikhipha u-802.11a / g / n noma i-802.11b / g / n. Labo abahlela i / g / n emazingeni we-Wi-Fi bazoba namandla okusebenzisa noma yi-spectrum ye-radio ngenkathi b / g / n izosebenzisa kuphela i-spectrum 2.4GHz. Qaphela ukuthi abanye abakwa-802.11b / g / n bangasebenzisa i-spectrum engu-5GHz. Labo abakha izintambo ezimbili banamakhono okusebenzisa kokubili 2.4 ne-5GHz. Lokhu kuphela okubaluleke kakhulu kulabo abafisa ukusebenzisa i-spectrum ye-5GHz yomsakazo ozuzisa ukuhlala ngaphansi kwezindawo eziningi zebanga lokuhamba elingcono ngenxa yokungxenyana okuncane.
Ama-laptops amaningi manje asebenzisa inethiwekhi entsha ye-Wi-Fi ye-5G. Lezi zisekelwe kumazinga angu-802.11ac. Le mikhiqizo ithi ikwazi ukufezekisa izinga lokudlulisela elifinyelela ku-1.3Gbps eliphindwe kathathu elilinganiselwa ku-802.11n futhi elifana nelenethiwekhi ye-wired. Njengesijwayelekile sama-802.11a, isebenzisa imvamisa ye-5GHz kodwa i-double-band echaza ukuthi ibuye isekele i-802.11n kumvuthwandaba we-2.4GHz.
Abasebenzisi abaningi bazobona izindinganiso eziningi ezifakwe kukhompyutha yekhompuyutha, njenge-802.11b / g. Lokhu kusho ukuthi ikhompyutha ye-laptop ingasetshenziswa nazo zonke izindinganiso ze-Wi-Fi ezibalwe. Ngakho-ke, uma ufuna ukuba nobubanzi obubanzi kunazo zonke zokuxhumana kwenethiwekhi, bheka ikhompuyutha ephathekayo efakwe ohlwini lwezinethiwekhi ezingenantambo ezingu-802.11ac noma 802.11a / g / n. Lokhu kungabuye kuthiwa yi-double-band 802.11n ngoba isekela i-spectrum engu-2.4GHz no-5GHz.
Nasi uhlu lwamanye amazinga we-Wi-Fi:
- I-802.11a - 54Mbps, i-5GHz Band, esetshenziswa kakhulu yizinkampani
- 802.11b - 11Mpbs, 2.4GHz Band
- 802.11g - 54Mbps, 2.4GHz Band
- I-802.11n - Kufike ku-450Mbps Standard, 2.4 noma i-5GHz Band
- I-802.11ac - Kufika ku-1.3Gbps, i-5GHz Band kodwa i-Backwards Iyahambisana namaqembu angu-2.4GHz nge-802.11n
I-Ethernet (I-Networking Wired)
Kuze kube yilapho inethiwekhi engenazintambo isakazeke kangaka, ukuxhumeka kwenethiwekhi okusheshayo kudinga ukusetshenziswa kwekhebula le-Ethernet elixhunywe kwi-laptop ukuya kudivayisi yedivayisi. I-Ethernet ibe yiklamo yekhebula ye-PC yenethiwekhi evamile iminyaka eminingi etholakala cishe kuwo wonke ama-computer. Ngokugcizelela kuma-laptops amancane afana ne- ultrabooks angenayo isikhala esidingekayo ku-port yekhebula, izinhlelo eziningi manje zilahla isikhombimsebenzisi esibonakalayo esingaziwa ngaso sonke isikhathi.
Kunezinhlobo ezimbili ezijwayelekile zezinga lika-Ethernet okwamanje. Okuvame kakhulu kuze kube yamuva kwaba yi-Fast Ethernet noma i-10/100 Ethernet. Lokhu kunesilinganiso sezinga eliphezulu sedatha ye-100Mbps futhi libuyela emuva lihambisana nesilinganiso esidala se-10Mbps Ethernet. Lokhu yilokho okutholakala kumagagasi amaningi okuxhumana abathengi njengamakhompiyutha wekhebula ne-DSL. I-standard standard yamuva i-Gigabit Ethernet. Lokhu kuvumela ukuxhaswa kokuxhumana kuze kufike ku-1000Mbps kumathuluzi wokuxhumana ahambisanayo. Njengo-Fast Ethernet, ibuyela emuva iyahambisana nezinhlobo zenethiwekhi ezihamba kancane.
Isivinini se-Ethernet isikhombimsebenzisi sizobaluleke kakhulu uma uxhuma phakathi kwamadivaysi kunethiwekhi yendawo (LAN) . Ukuxhumeka okuningi kwe-broadband kuhamba kancane kunezinga eliphansi le-Fast Ethernet nakuba lokhu sekuqala ukushintsha ngamanethiwekhi amaningi aphezulu we-fiber efakwe.
I-Bluetooth
I-Bluetooth iyi-standard standard wireless standard esebenzisa i-spectrum engu-2.4GHz njenge-Wi-Fi. It is ngokuyinhloko esetshenziselwa uxhumano wireless uxhumano kunokuba zangempela zokuxhumana. Kunesici esisodwa esingasetshenziselwa futhi esilungisela ifoni engenantambo . Lokhu kuvumela i-laptop ukuthi isebenzise isixhumanisi sedatha yefoni engenantambo. Ngeshwa, eziningi zezintambo zefoni ezingenazintambo e-United States azivumeli ukufaka ama-tethering noma zinezikhwama ezingaphezulu ukuze zinike amandla ngedivayisi. Hlola nenkampani yakho yenethiwekhi uma lokhu kuyisici ongase unesithakazelo kuso. Lesi sici sincane kakhulu manje kodwa ngenxa yamandla we-Wi-Fi hotspot we-Smartphones.
I-Wireless / 3G / 4G (WWAN)
Ukufakwa kwamamodemu angenantambo angakhelwe ngaphakathi noma ama-adapter we-3G / 4G wokuxhumanisa ukuxhumeka kwamakhompiyutha ephathekayo. Abakhiqizi bavame ukubhekisela kulokhu njengezinethiwekhi zokuxhumana ezingenazintambo ezingenantambo noma i-WWAN. Lokhu kungavumela ikhompyutha ephathekayo ukuba ixhumane ne-intanethi ngokusebenzisa inethiwekhi yefoni engenazintambo ezingenazintambo lapho kungekho okunye ukufinyelela okungenzeka khona. Lokhu kungasiza kakhulu kodwa futhi kuyabiza kakhulu njengoba kudinga izinkontileka ezikhethekile zedatha. Ngaphezu kwalokho, imodemu engenawaya eyakhiwe kuma-laptops ngokuvamile ivalwe kumhlinzeki othile noma isigaba senethiwekhi. Ngenxa yalokho, angikhuthazi abasebenzisi ukuthi babheke lezi zici futhi bathenge i-modem yangaphandle engenawaya esebenzisa i-USB uma udinga ngempela inkonzo enjalo. Enye indlela yidivayisi ye- hotspot yeselula ehlanganisa ngokuzenzakalelayo umzila we-Wi-Fi kumodemu engenantambo. Zisadinga izinkontileka zedatha kepha zinekhono lokusetshenziselwa cishe nganoma yisiphi idivayisi esebenzayo ye-Wi-Fi.
Amamodeli
Uma usuhlobo olubaluleke kunazo zonke zokuxhumana, ama- modem ayatholakali kunoma iyiphi i-laptops manje. Ukuxhumeka kwenethiwekhi kokudayela kungenye yamafomu amadala okuxhumana ngama-computer e-PC. Ngenkathi uxhumano lwe-broadband luvame kakhulu ekhaya, uma sisendleleni ezindaweni ezikude lokhu kungaba yindlela kuphela yokuxhuma. Ikhebula lefoni elula lixhunyiwe kwi-laptop futhi i-jack yefoni ivumela umsebenzisi ukuba axhume nge-akhawunti yokudayela. Ngenkathi ama-laptops amaningi angase angabonakali lawa machweba, kungenzeka njalo ukuthenga i-modem yokubiza i-USB ebiza izindleko eziphansi ukuyisebenzisa cishe nganoma iyiphi ikhompyutha. Okuhle kakhulu ukuthi imodemu ye-analog ngokuvamile ayisebenzisi imigqa eminingi ye-VoIP ngenxa yokucindezelwa kwedatha.
Ngenxa yokulinganiselwa kokudluliselwa kwedatha yomsindo kumigqa yocingo, isivinini esikhulu se-56Kbps sesifinyelelwe isikhathi esithile. Noma iyiphi i-laptop ephethe i-modem izoba ngu-56Kbps ehambisanayo. Umehluko okuwukuphela kobe kubalwe njengohlobo lwe-v.90 noma lwe-v.92. Lezi zindlela ezimbili zokuxhumana kwedatha futhi zishintsha kakhulu uma kuziwa ekuxhumaneni kwangempela kokudayela.
