🧠 QUIC nima uchun xizmat qiladi?
QUIC protokoli quyidagi muammolarni hal qilish va internetda tezroq, xavfsizroq aloqani ta’minlash uchun yaratilgan:

✅ 1. Yuqori tezlikda ma’lumot almashish
TCP dan farqli o‘laroq, UDP asosida ishlaydi, shuning uchun aloqani o‘rnatish va ma’lumot uzatish tezroq bo‘ladi.

TCP'da "3-way handshake" bo‘lsa, QUIC'da bitta paket bilan aloqa o‘rnatiladi.

✅ 2. TLS (Transport Layer Security) ni ichiga olgan
QUIC xavfsizlikni avtomatik ta'minlaydi (TLS 1.3 integratsiyalashgan).

Alohida HTTPS aloqasi talab qilinmaydi — birinchi paketdayoq shifrlash bo‘ladi.

✅ 3. Packet loss (paket yo‘qolishi) ta’sirini kamaytiradi
TCP'da bitta paket yo‘qolsa, butun oqim to‘xtab qoladi (head-of-line blocking).

QUIC bu muammoni hal qiladi va boshqa oqimlar ishlashda davom etadi.

✅ 4. Mobil qurilmalarda aloqa uzilishini sezdirmaslik
IP manzilingiz o‘zgarsa (masalan: Wi-Fi → mobil internet), QUIC sessiyani uzmasdan davom ettiradi.

🌐 QUIC protokolining qo‘llanilishi
HTTP/3 protokoli faqat QUIC asosida ishlaydi.

Google Chrome, YouTube, Facebook, Cloudflare, Zoom va boshqa yirik xizmatlar QUIC’ni faol ishlatadi.

CDN va video streaming platformalarda kechikish (latency) kam bo‘ladi.

🔐 Xavfsizlik tarafidan:
QUIC shifrlangan bo‘lib, tarmoq darajasida inspeksiya qilish qiyin. Shu bois ayrim xavfsizlik tizimlari (DPI, IDS/IPS) uchun murakkablik tug‘diradi.

📌 Xulosa:
Afzalliklari Tavsifi
Tez aloqa UDP orqali, 1 paketda ulanish
Xavfsiz TLS 1.3 integratsiyasi
Ma’lumot yo‘qolishiga chidamli Head-of-line blocking yo‘q
Mobil aloqa uchun mos Sessiya uzilmaydi

Should I buy bitcoin?

“To the extent it is used I fear it’s often for illicit finance. It’s an extremely inefficient way of conducting transactions, and the amount of energy that’s consumed in processing those transactions is staggering,” the former Fed chairwoman said. Yellen’s comments have been cited as a reason for bitcoin’s recent losses. However, Yellen’s assessment of bitcoin as a inefficient medium of exchange is an important point and one that has already been raised in the past by bitcoin bulls. Using a volatile asset in exchange for goods and services makes little sense if the asset can tumble 10% in a day, or surge 80% over the course of a two months as bitcoin has done in 2021, critics argue. To put a finer point on it, over the past 12 months bitcoin has registered 8 corrections, defined as a decline from a recent peak of at least 10% but not more than 20%, and two bear markets, which are defined as falls of 20% or more, according to Dow Jones Market Data.
