Ndi ma megabra angati pawiri zofunika pa kanema, masewera ndi zina.
Ku Russia, zabwino kwambiri komanso, zochepa, zotsika mtengo, zotsika mtengo zapakhomo. Kwambiri! M'midzi ndi chigawo chozama cha bizinesi, zachilendo, choyipa, koma tengani aliyense, ndiye tawuni yaying'ono ku Europe ya dzikolo ndikuwona mitengoyo. Kwa 300-400 ma rubles pamwezi, intaneti imatha kukhazikitsidwa m'nyumba mothamanga kwambiri, ndipo kwa ena akukwezedwa ndi ma megabi othamangitsa 100.
Poyerekeza: "Chitukuko", intaneti yofulumira (ndipo nyumba ndi mafoni) imawononga ndalama zambiri. Ndipo komabe amakhalabe lingaliro la "malire a data pamwezi". Tili ndi ma cell a cell.
Komabe, kutsika mtengo si chifukwa cholipira zomwe simugwiritsa ntchito. Ngakhale ma ruble ambiri opulumutsidwa amawotcha chikwamacho, chifukwa chake mitengo yanyumba yanyumba iyenera kusankhidwa potengera zosowa zenizeni. Tiyeni tiwone kuchuluka kwa megabit yomwe imafunidwa pa yachiwiri pa zochitika zosiyanasiyana, ndikuyamba ndi mfundo zazikulu.
Megabits, megabytes ndi kuthamanga kwenikweni
Kukula kwa data kumachitika mu ma bytes. Mwachitsanzo, kanema wa HD amalemera kuchokera ku 700 megabytes (megov) mpaka 1.4 Gigabytes (Giga), ndi HD yonse ndi kuyambira 4 mpaka 14 Gigabytes.Kutumiza kwa data kumalandiridwa m'makola (osakhala ndi ma BUTTT!) Pa sekondi imodzi, ndipo nthawi zina zimayambitsa kusamvana.
Byte ≠ pang'ono.
1 Byte = 8 zakumwa.
1 megabyte = 8 megabits.
1 megabyte pa sekondi iliyonse = 8 megabits pawiri.
Ngati wogwiritsa ntchitoyo sasiyanitsa maste ndi ma bits, amatha kusokonezedwa mosavuta kapena kutetezedwa pazomwezi. Pankhaniyi, idzawerengera nthawi yotsitsa ya HD kudzera pa mtsinje ngati izi:
- Pulogalamuyi imalemera 1,400 "Megav".
- Kuthamanga pa intaneti 30 "Megav" mphindi iliyonse.
- Kanemayo amatsitsidwa kwa 1,400 / 30 = 46..6 masekondi.
M'malo mwake, kuthamanga kwa intaneti ndi njira 30 pa sekondi = 3.75 megabytes iliyonse. Chifukwa chake, 1,400 megabytes ayenera kugawidwa ndi 30, koma pofika 3.75. Pankhaniyi, nthawi yotsitsayo idzakhala 1 400 / 3.75 = masekondi 373.
Pochita izi, liwiro lidzakhala lotsika, chifukwa opereka intaneti amawonetsa liwiro "kuti", ndiye kuti, ndizotheka kwambiri, osagwira ntchito. Kuphatikiza apo, pamakhala kusokoneza, makamaka mukakhala ndi katundu wa Wi-Fi, pa intaneti, komanso zofooka ndi zida zopereka zaogwiritsa ntchito. Mutha kuyang'ana liwiro lanu mothandizidwa ndi ntchito zapadera, ndikuwonjezera - mothandizidwa ndi malangizowa.
Nthawi zambiri khosi limakhala gwero lomwe mumasinthira china. Mwachitsanzo, kuthamanga kwa intaneti yanu ndi ma megabits 100 pa sekondi, ndipo malowa amapereka deta pothamanga kwa mphindi 10 pawiri. Pankhaniyi, kutsitsidwa kumachitika mwachangu osapitilira 10 segabits pa sekondi iliyonse, ndipo palibe chochita nazo.
Kuthamanga kwa intaneti ndi chiyani?
| Mtundu wa zochitika | Liwiro lolimbikitsidwa (ndi Reserve), megabit sekondi iliyonse |
| Kusaka, Makalata, Magulu (Popanda makanema ndi zithunzi zazikulu) | 2. |
| Masewera a pa intaneti | 2. |
| Kulimbana ndi Kanema | 3. |
| SD Video (360p, 480p) | 3. |
| HD Video (720p) | zisanu |
| Kanema wa HD (1 080p) | zisanu ndi zitatu |
| 2k video (1 440p) | 10 |
| 4k video (2 160p) | 25 ndi kuposa |
Mwachidziwikire, tebulo loperekedwa pamwamba pamafunika kufotokozera.
Mafunso ndi Mayankho
Kodi mungatani ngati intaneti imagwiritsidwa ntchito nthawi yomweyo pazida ziwiri kapena zingapo?
Tiyerekeze kuti mukuyang'ana vidiyo yathunthu ya HD pa TV yanzeru, mkazi wanga kuseri kwa laputopu ndi ntchentche ya HD-Screen, ndipo mwana amawoneka kuchokera pa smartphone kapena piritsi. Kodi izi zikutanthauza kuti manambala ochokera patebulo amafunikira ndalama?Inde, zoona. Pankhaniyi, mufunika ma megarab 20 pawiri.
Kodi ndi chifukwa chiyani malo osiyanasiyana amapereka zofuna kuthamanga kuti muwone kanema wa chilolezo chomwechi?
Pali lingaliro lotereli ngati mtengo wochepa - kuchuluka kwa chidziwitso chomwe chithunzicho chimasungidwa pa nthawi yake, ndipo, moyenerera, chizindikiritso cha chithunzicho ndi mawu. Mulingo wokwera pang'ono, chithunzi chabwinoko. Ichi ndichifukwa chake pamitsinje yomwe mungapezenso mafilimu ofanana ndi lingaliro lomwelo, koma la kukula kwake.
Kuphatikiza apo, pali kanema wapamwamba kwambiri wokhala ndi mafelemu 60 pa sekondi. Amalemera kwambiri ndipo amafunikira intaneti yothamanga kwambiri.
Kodi ndizowona kuti masewera a pa intaneti ndi sitikudana kwambiri ndi kuthamanga kwa intaneti?
Inde, zoseweretsa zambiri ngati CS, Dota 2, WOT, Wow ndi ngakhale GTA 5 Kubwerera. Ocheperako ma ping, osachedwa pamasewera.Tsoka ilo, ndizosatheka kudziwa pasadakhale ngakhale pafupifupi masewera omwe ali pamasewera ena kudzera mwa omwe akupereka, chifukwa mtengo wake ndiosavuta ndipo zimatengera zinthu zambiri.
Chifukwa chiyani nthawi yamavidiyo imayimba chithunzi ndi mawu ochokera kwa olumikiza kwa ine ndikwabwino, ndipo kuchokera kwa ine kupita kwa iwo - ayi?
Pankhaniyi, zimakhala zofunikira osati zobwera zokhazokha, komanso liwiro la intaneti. Nthawi zambiri, opereka sawonetsa liwiro lotuluka m'ngalawa, koma mutha kudzifufuza nokha pogwiritsa ntchito njira yomweyo.net.
Kufalitsa pawebusayiti, pali velocity yokwanira 1 megabit sekondi iliyonse. Pankhani ya makamera a HD (ndi zochulukirapo, HD), zofuna zowonjezereka.
Kodi nchifukwa ninji opereka intaneti m'mitengo amayamba ndi 20-30 ndi kuchuluka kwa megarabits pawiri?
Chifukwa kuthamanga kwapamwamba, ndalama zambiri zomwe mungatenge nanu. Othandizira amatha kusungitsa misonkho "kuchokera m'mbuyomu" pothamanga kwa 2-10 megabits pa sekondale ndikuchepetsa mtengo wake mpaka 50-100 rubles, koma chifukwa chiyani? Ndizopindulitsa kwambiri kukulitsa liwiro ndi mitengo yaying'ono.
