- Https is a protocol used to secure websites from being tampered with by other parties without proper authorization. it bridges the gap between sender and receiver.Using protocols like secure socket layer/TLS, HTTPS encrypts data sent over the internet, making it unreadable to anybody who shouldn't have it.This prevents a "man in the middle" assault on the system.Such assaults intercept messages before they reach their intended recipient.It then transmits the revised information to the user.It guarantees the server's authenticity, too.arrow_forwardExplain four protocols to prevent deadlock. What is the limitation of preventing deadlock?arrow_forwardWhen a file is transferred between two computers, two acknowledgement strategies are possible. In the first one, the file is chopped up into packets, which are individually acknowledged by the receiver, but the file transfer as a whole is not acknowledged. In the second one, the packets are not acknowledged individually, but the entire file is acknowledged when it arrives. Discuss these two approaches.arrow_forward
