Regarding a peer-to-peer file-sharing program, do you agree that "there is no feeling of client and server sides of a communication session"? Why is this happening, or why is it not happening?
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.
Facebook is one of the most popular social networks where users can post posts to different (text or image) and comment on them • Each user must register beforehand in order to use the system. The user is identified by a name, surname, date of birth, email address (which will also serve for authentication) and a password. • Any user can make a post which contains a text and/or image. Post is identified by a unique code, text used, an identification code for the image and date of post. • A user (including the author of the post) can comment on the post. The comment is characterized by an identification code, text, and date of post. Also, a user may like a comment or post. The system should keep track which user has liked the post/comment, etc. • Users can also exchange messages with each other. Each message is characterized from the unique code, text, date and time of sending as well as information if the recipient has seen the message or not. Write the rational schema, normalization -…
The practise of "save and forward" has been all but eliminated from regular communication. Inspect the workings.
Cypher block chaining and cypher feedback mode may be compared with regards to the number of encryption operations needed to transmit a large file.How much more efficient is one option than the other?
Explain why a stream cipher fails to protect message integrity?
One of the problems with the Internet email system is that sending forged emails is relatively straightforward, i.e., it is easy to send an email with a fake sender/from address. One solution to this problem would be for a domain’s mail servers to digitally sign any email originating from the domain. For this to be useful, the public key would need to be made available to clients to validate the signatures. It is proposed that the public keys of the mail servers will be verified and signed by a certification authority (same as SSL/TLS certificates) and distributed via a standardised URL for the domain, e.g., https://mybusiness.com/email.pubkey. (a) Explain how the client would obtain the public key and validate the email server’s digital signatures. (b) Discuss the problem of trusting the obtained public key and how this solution results in public keys that can/cannot be trusted. (c) Indicate whether you believe this approach could be used to prevent forged emails and explain why it…
Catalog DNS records by the kind of record they include. Each one is shown with examples, and its use is discussed. Is it conceivable, in your opinion, to have a web server with the same name as an email server?
When users post an update on social media,such as a URL, image, status update etc., other users in their network are able to view this new post on their news feed. Users can also see exactly when the post was published, i.e, how many hours, minutes or seconds ago. Since sometimes posts are published and viewed in different time zones, this can be confusing. You are given two timestamps of one such post that a user can see on his newsfeed in the following format: Day dd Mon yyyy hh:mm:ss +xxxx Here +xxxx represents the time zone. Your task is to print the absolute difference (in seconds) between them. Input Format The first line contains , the number of testcases.Each testcase contains lines, representing time and time .

Make a list of DNS entries and arrange them according to the kind of record each one includes. Examples and an explanation of why each of them should be used have been given for each one. Do you think it's possible to use the same name for both a mail server and a web server at the same time?
