پرسیدید؛ چرا AND انجام شده؟
هرعددی نهایتاً بصورت binary توی کامپیوتر ذخیره میشه مثلاً 10 میشه (۸بیتی در نظر بگیریم) 00001010
یا برای 5 میشه 00000101
اولین عدد سمت راست همیشه 2⁰ رو ضربدر خودش می‌کنه تا به دسیمال همون سیستم عددی خودمون تبدیل بشه.2⁰=1
هست، پس اگر سمت راستی ترین بیت 1 باشه اون عدد فرد هست.

A Telegram spokesman declined to comment on the bond issue or the amount of the debt the company has due. The spokesman said Telegram’s equipment and bandwidth costs are growing because it has consistently posted more than 40% year-to-year growth in users.
Telegram’s stand out feature is its encryption scheme that keeps messages and media secure in transit. The scheme is known as MTProto and is based on 256-bit AES encryption, RSA encryption, and Diffie-Hellman key exchange. The result of this complicated and technical-sounding jargon? A messaging service that claims to keep your data safe.Why do we say claims? When dealing with security, you always want to leave room for scrutiny, and a few cryptography experts have criticized the system. Overall, any level of encryption is better than none, but a level of discretion should always be observed with any online connected system, even Telegram.
