A network packet is a basic unit of data that's grouped together and transferred over a computer network
|
Tarmoq paketi - bu guruhlangan va kompyuter tarmog'i orqali uzatiladigan ma'lumotlarning asosiy birligi
|
A network packet’s parts: packet header, payload and trailer
|
Tarmoq paketining qismlari: paket sarlavhasi, foydali yuk va treyler
|
The headers of IPv6 packets are 40 bytes (unlike IPv4 with 20 -24 bytes)
|
IPv6 paketlarining sarlavhalari 40 bayt (20-24 baytli IPv4 dan farqli o'laroq)
|
Just like the postal system routes postal letters around the world, the Internet Protocol routes IP packets around the Internet.
|
Pochta tizimi pochta xatlarini butun dunyo bo'ylab yo'naltirganidek, Internet protokoli IP paketlarni Internet bo'ylab yo'naltiradi.

The Hypertext Transfer Protocol (HTTP) is an application protocol for distributed, collaborative, hypermedia information systems that allows users to communicate data on the World Wide Web.
|
Gipermatnni uzatish protokoli (HTTP) - bu tarqatilgan, hamkorlikda ishlaydigan, gipermedia axborot tizimlari uchun dastur protokoli bo'lib, u foydalanuvchilarga World Wide Webda ma'lumotlarni uzatish imkonini beradi.
|
Transport Layer Security (TLS) encrypts data sent over the Internet to ensure that eavesdroppers and hackers are unable to see what you transmit which is particularly useful for private and sensitive information such as passwords, credit card numbers, and personal correspondence.
|
Transport Layer Security (TLS) tinglovchilar va xakerlar siz uzatayotgan narsalarni koʻra olmasligini taʼminlash uchun Internet orqali yuborilgan maʼlumotlarni shifrlaydi, bu ayniqsa parollar, kredit karta raqamlari va shaxsiy yozishmalar kabi shaxsiy va maxfiy maʼlumotlar uchun foydalidir.
|
A Domain Name System (DNS) turns domain names into IP addresses, which allow browsers to get to websites and other internet resources. Every device on the internet has an IP address, which other devices can use to locate the device.
|
Domen nomlari tizimi (DNS) domen nomlarini IP manzillarga aylantiradi, bu esa brauzerlarga veb-saytlar va boshqa internet resurslariga kirish imkonini beradi. Internetdagi har bir qurilmaning IP-manzili mavjud bo'lib, boshqa qurilmalar qurilmaning joylashuvini aniqlash uchun foydalanishi mumkin.

Transmission Control Protocol (TCP) is a communications standard that enables application programs and computing devices to exchange messages over a network. It is designed to send packets across the internet and ensure the successful delivery of data and messages over networks.
|
Transmission Control Protocol (TCP) - bu amaliy dasturlar va hisoblash qurilmalariga tarmoq orqali xabar almashish imkonini beruvchi aloqa standarti. U Internet bo'ylab paketlarni jo'natish va ma'lumotlar va xabarlarni tarmoqlar orqali muvaffaqiyatli yetkazib berishni ta'minlash uchun mo'ljallangan.
|
Universal Computer Protocol (UCP) is a standard for transmitting short messages over cellular networks. The system first emerged in the 1980s and has since been expanded with the adoption of the External Machine Interface (EMI) standard.
|
Umumjahon kompyuter protokoli (UCP) uyali tarmoqlar orqali qisqa xabarlarni uzatish uchun standartdir. Tizim birinchi marta 1980-yillarda paydo bo'lgan va keyinchalik tashqi mashina interfeysi (EMI) standartining qabul qilinishi bilan kengaytirildi.
|
Ethernet is a network standard that specifies no central computer or device on the network (nodes) should control when data can be transmitted. That is, each node attempts to transmit data when it determines the network is available to receive communications. The Ethernet standard defines guidelines for the physical configuration of a network (e.g., cabling, network devices, and nodes). Network range: from 10 Mbps for home/small office users to 100 Gbps for enterprise users
|
Ethernet - bu tarmoq standarti bo'lib, tarmoqdagi (tugunlarda) hech qanday markaziy kompyuter yoki qurilma ma'lumotlar uzatilishini nazorat qilishi kerak emas. Ya'ni, har bir tugun tarmoq aloqalarni qabul qilish uchun mavjudligini aniqlaganida ma'lumotlarni uzatishga harakat qiladi. Ethernet standarti tarmoqning jismoniy konfiguratsiyasi (masalan, kabellar, tarmoq qurilmalari va tugunlar) uchun ko'rsatmalarni belgilaydi. Tarmoq diapazoni: uy/kichik ofis foydalanuvchilari uchun 10 Mbit/s dan korporativ foydalanuvchilar uchun 100 Gbit/s gacha
|
A wireless LAN (WLAN) is a wireless computer network that links two or more devices using wireless communication to form a local area network (LAN) within a limited area such as a home, school, computer laboratory, campus, or office building
|
Simsiz LAN (WLAN) bu uy, maktab, kompyuter laboratoriyasi, kampus yoki ofis binosi kabi cheklangan hududda mahalliy tarmoqni (LAN) hosil qilish uchun simsiz aloqa yordamida ikki yoki undan ortiq qurilmalarni bog'laydigan simsiz kompyuter tarmog'idir.

What is the difference between a switch and a hub and a router?
|
Kommutator, hub va router o'rtasidagi farq nima?
|
The difference between hub, switch and router is that these devices all serve very diverse purposes and have very different applications. The main difference between hub, switch and router are that hub is a physical layer device, a switch is a data link layer device, and router is a network layer device.
|
Hub, switch va router o'rtasidagi farq shundaki, bu qurilmalarning barchasi juda xilma-xil maqsadlarga xizmat qiladi va juda xilma-xil ilovalarga ega. Hub, switch va router o'rtasidagi asosiy farq shundaki, hub jismoniy qatlam qurilmasi, kalit ma'lumotlar havolasi qatlami qurilmasi va router tarmoq qatlami qurilmasi.

LTE (Long Term Evolution) is a network standard that defines how high-speed cellular transmissions use broadcast radio to transmit data for mobile communications.
|
LTE (Long Term Evolution) - bu tarmoq standarti bo'lib, u mobil aloqa uchun ma'lumotlarni uzatish uchun yuqori tezlikdagi uyali aloqa uzatish radioeshittirishdan qanday foydalanishini belgilaydi.
|
Developed by the Third Generation Partnership Project (3GPP), LTE has the potential of 100 Mbps downstream rate (receiving data) and 30 Mbps upstream rate (sending data).
