❔ Вопрос с собеседования

Что такое MongoDB и чем она отличается от SQL-баз?

Ответ: MongoDB — это документо-ориентированная NoSQL база данных, в которой данные хранятся в виде документов формата BSON (расширенный бинарный JSON).

В отличие от SQL-баз, она не требует фиксированной схемы, легко масштабируется и чаще применяется там, где важна гибкость структуры данных.

What is Secret Chats of Telegram

Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.

Telegram Q&A
Q: How does hottg.com work?
Once you've set up a username, you can give people a hottg.com/username link. Opening that link on their phone will automatically fire up their Telegram app and open a chat with you. You can share username links with friends, write them on business cards or put them up on your website.This way people can contact you on Telegram without knowing your phone number.

With Telegram, you can send messages, photos, videos and files of any type (doc, zip, mp3, etc), as well as create groups for up to 200,000 people or channels for broadcasting to unlimited audiences. You can write to your phone contacts and find people by their usernames. As a result, Telegram is like SMS and email combined — and can take care of all your personal or business messaging needs. In addition to this, we support end-to-end encrypted voice calls.
