DNS sozlamalari orqali internetni tezlashtiramiz #info / #internet
ℹ️ Internetda biror saytga kirish uchun brauzerning manzil qatoriga uning manzilini teramiz, Enter tugmachasini bosamiz – bo‘ldi. Yoki tayyor xatcho‘p (zakladka)lardan foydalanamiz – bunisi yanada oddiy.
Ammo shu oddiylik ortida dasturchilarning mehnati va internet jihozlarining ishi yotganini ko‘pincha xayolimizga ham keltirmaymiz. Deylik, bizga o‘sha saytni ochib berish uchun kompyuter «manzillar kitobchasiga ko‘z tashlaydi», domen nomlari serveri – DNS’ga so‘rov yuboradi va javobni kutadi. Kerakli sahifaning qanchalik tez ochilishi faqatgina ulanish tezligiga emas, balki DNS’ning tezkorligiga ham bog‘liq. Xo‘sh, uning ishlashiga biz ta’sir ko‘rsatib, internetni tezlashtira olamizmi?

You may recall that, back when Facebook started changing WhatsApp’s terms of service, a number of news outlets reported on, and even recommended, switching to Telegram. Pavel Durov even said that users should delete WhatsApp “unless you are cool with all of your photos and messages becoming public one day.” But Telegram can’t be described as a more-secure version of WhatsApp. Russians and Ukrainians are both prolific users of Telegram. They rely on the app for channels that act as newsfeeds, group chats (both public and private), and one-to-one communication. Since the Russian invasion of Ukraine, Telegram has remained an important lifeline for both Russians and Ukrainians, as a way of staying aware of the latest news and keeping in touch with loved ones. For example, WhatsApp restricted the number of times a user could forward something, and developed automated systems that detect and flag objectionable content. NEWS "The result is on this photo: fiery 'greetings' to the invaders," the Security Service of Ukraine wrote alongside a photo showing several military vehicles among plumes of black smoke.
