Design a circuit that adds four 10-bit unsigned binary values and outputs an unsigned binary 10-bit result. The circuit also has a VALID output that indicates when the 10-bit unsigned binary result is valid. Note that when you add two 10-bit numbers, you will generate an 11-bit result (in some cases). Show the top two levels for this solution, meaning a top-level BBD, and the next lower level, which is RCAs and some gates. There is no need to show the next lower level, which would be the gate-level view of the RCAs. State how the circuit is controlled.

What a backup plan that you have created in a event you encounter a situation

What is the main benefit of minimizing the ribbon in word? more options will be accessible through customized keystrokes. more of the document will be viewable without needing to scroll. fewer controls will be accessible to the user by using the mouse. fewer editing options will be available without entering a password.

Given a link with a maximum transmission rate of 32.8 mbps. only two computers, x and y, wish to transmit starting at time t = 0 seconds. computer x sends filex (4 mib) and computer y sends filey (244 kib), both starting at time t = 0. statistical multiplexing is used, with details as follows packet payload size = 1000 bytes packet header size = 24 bytes (overhead) ignore processing and queueing delays assume partial packets (packets consisting of less than 1000 bytes of data) are padded so that they are the same size as full packets. assume continuous alternating-packet transmission. computer x gets the transmission medium first. at what time (t = ? ) would filey finish transmitting? give answer in milliseconds, without units, and round to one decimal places (e.g. for an answer of 0.013777 seconds you would enter "13.8" without the quotes)
