Design and describe an application-level protocol to be used between an automaticteller machine (ATM) and a bank's centralized computer.a) Your protocol should allow a user's card and password to be verified, the accountbalance (maintained at the centralized computer) to be queried, and an accountwithdrawal to be made. Your protocol entities should be able to handle the all-too-common case in which there is INSUFFICIENT BALANCE on the account tocover the withdrawal. Specify your protocol by listing the messages exchangedand the action taken by the ATM or the bank's centralized computer ontransmission and receipt of messages.b) Sketch the operation of your protocol for the case of a simple withdrawal withno errors, using a diagram similar to that in Figure 1 below.c) Explicitly state the assumptions made by your protocol about the underlyingend-to-end transport service.Page 4 of 5Р.

Draw context level diagram for the below case. • Digitech is a digital TV company that offers high bandwidth TV connection with different options (entertainment package, sports package, etc.). • Customers can get information for promotions by calling and speaking to a live assistant. The information will be given by the assistant who uses the system to retrieve the information. • Assistant asks for the telephone number of the customer, enters the number into the system and receives customer’s general information and then checks the validity of this information with the customer. If the information is not valid, assistant hangs up the telephone and enters an explanation to the system. • When the information is valid, assistant retrieves the promotion information that is available for that specific customer and gives that information to the customer. After this operation assistant retrieves company specified promotions and also gives information about those promotions. If the…

Computer Science Draw the sequence diagram for a typical, older, "classic", single-window-drive-through fast-food restaurant protocol. For this use case, assume no online pre-ordering; assume a single pay and get your food window. Use 3 roles (human actors) -- imagine who would be most important in this process -- and 3 system objects (the microphone/speaker "board"; the window attendantʻs console (display/keypad); the cookʻs console) to describe the system for ordering. Include some typical messages
