Client:
In
Server:
In computer network, a server is a computer program that provides services to other computer programs. A server usually accepts requests made by the client and provides its services to the client.
For a communication session between a pair of processes in computer network, the process which initiates the communication is called a client as a client usually asks for requests and the process that waits to be contacted is the server as the server accepts the requests made by the client.
Round Trip Time:
The length of time it takes for a signal to be sent along with the length of time to be acknowledged is called the round trip time.

- Given the following addresses, which two addresses conflict in the cache: The numb of locations in the cache is 2048, the cahche is indexed by address bits 15 to 5 and the tag bits are from 31 to 16. (a) 0x0000 0100 (b) 0x0000 1400 (c) 0x0010 0100 (d) 0x0100 0140arrow_forward5. RetailItem ClassWrite a class named RetailItem that holds data about an item in a retail store. The class should store the following data in attributes: item description, units in inventory, and price. Once you have written the class, write a program that creates three RetailItem objects and stores the following data in them: Description Units in Inventory PriceItem #1 Jacket 12 59.95Item #2 Designer Jeans 40 34.95Item #3 Shirt 20 24.95arrow_forwardWrite a class named Patient that has attributes for the following data: First name, middle name, and last name Address, city, state, and ZIP code Phone number Name and phone number of emergency contact The Patient class’s _ _init_ _ method should accept an argument for each attribute. The Patient class should also have accessor and mutator methods for each attribute. Next, write a class named Procedure that represents a medical procedure that has been performed on a patient. The Procedure class should have attributes for the following data: Name of the procedure Date of the procedure Name of the practitioner who performed the procedure Charges for the procedure The Procedure class’s _ _init_ _ method should accept an argument for each attribute. The Procedure class should also have accessor and mutator methods for each attribute. Next, write a program that creates an instance of the Patient class, initialized with sample data. Then, create three instances of the Procedure class,…arrow_forward

Z 13x1 +11x2 Subject to constraints 4x1 +5x21500 5x1 +3x21575 x1 +2x2 <420 x1, x2≥0arrow_forwardBasically, you must build a desktop/android application that utilizes cryptographic techniques/protocols to secure communication (or data at rest). Try to achieve confidentiality, integrity, availability, authentication, non-repudiation (preferably all of them, otherwise few of them based on the requirement).You must demonstrate the use of these cryptographic techniques by showing some outputs/visualization results or captured traffic such as through Wireshark.1. Secure Chat ApplicationDescription: Build an encrypted chat application for desktop or Android that ensures confidentiality, integrity, authentication, and non-repudiation.Features:-- End-to-end encryption using AES-256 or Signal Protocol.--Digital signatures for non-repudiation.--Message integrity verification using HMAC.Secure login using two-factor authentication (2FA).--Server-side availability mechanisms (e.g., load balancing, backup storage).
