يقول أهل العلم أن الحفظ لا يكون إلا في الغرف المغلقة ..
وهذا يشير إلى أن اللي يشتي يحفظ ويتعلم ضروري انه يعزل نفسه عن كل ما يشغل ذهنه ويشتت تفكيره ..
ومع ذلك ألاحظ بعض الطلاب يذاكر اختباراته في المقاهي والحدائق العامة ..
هل المذاكرة في هذه الأماكن مجدية؟
أم مجرد استعراض؟!

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.
