Computer Systems In your implementation of the ALU there is no need to detect or handle overflow. However, it's a good mental exercise to think about when/how an overflow might occur. When adding numbers with different signs, overflow cannot occur because the sum must be no larger than one of the numbers. What happens when the signs of the numbers are the same? What happens in the case of subtraction? How do we detect when an overflow does occur?

The Famous Gauss You must know about Gauss, the famous mathematician. Back in late 1700’s, he was at elementary school. Gauss was asked to find the sum of the numbers from 1 to 100. The question was assigned as “busy work” by the teacher. He amazed his teacher with how quickly he found the sum of the integers from 1 to 100 to be 5050. Gauss recognized he had fifty pairs of numbers when he added the first and last number in the series, the second and second-last number in the series, and so on. For example:(1 + 100), (2 + 99), (3 + 98), ..., (50 + 51). Each pair has a sum of 101 and there are 50 pairs. History repeats itself. Jojo’s teacher assign a “busy work” to the students. The teacher believes that there will be no shortcut to finish this task in a minute. The teacher gives N integers A1, A2, ..., AN to the students. The teacher also gives Q questions. Each question contains two integers L and R asking the sum of all Ai where L <= Ai <= R. As a good friend of Jojo, help Jojo…
Can you think of any issues that emerge when a computer is limited to storing and working with numbers only? The situation is not good at the moment. Our next steps are.
Using any digital flowcharting tool ( Lucidchart, Vizio), write 4 UML functions. Each one should take in a pair of numbers and then print out all integer values between (and including) those two numbers. You may assume the lower number comes first. Use these 4 types of loop for each of the four functions: while, do-while, automatic counter, and recursion. Clearly identify each one.
In MIPS assembly, implement integer division using rounding (rather than truncation). This is accomplished by taking the remainder of the division and dividing it by the original divisor. If the new quotient is higher than or equal to one, multiply it by one.Otherwise, leave the original quotient alone.In MIPS assembly, implement integer division using rounding (rather than truncation).

What exactly does "widen conversion" entail when it comes to the field of computer science?
In my Introduction to Electronics course (300), we often run across division by zero. I know that it is technically undefined (or, at the very least, ambiguous), but sometimes we consider the value to be zero and other times to be infinity, which are, obviously, diametrically different (apart from negative numbers). I'm not so much interested in the nature of division by zero but more in how we determine whether we regard the value as zero or infinity? Again, this is in the context of electronics and circuit analysis, to be more specific. Thank you for your assistance.
We speak of programs’ being “partially” correct and being “totally” correct. A program is totally correct just when it does what any reasonable person would expect from its specification: if started in a situation (“state” of the computer) where its pre-condition holds, then it eventually terminates in a case where its post condition has.Are these two partially and totally in terms of what they imply about the specification for the pre-condition and post-condition? If so, explain precisely what they mean in this regard. If not, explain what is different about what they imply.
Write the matlab code for the following problem The following iterative sequence is defined for the set of positive integers: n - n/2 (n is even) n - 3n + 1 (n is odd) Using the rule above and starting with 13, we generate the following sequence: 13 - 40 → 20 → 10 → 5 -→ 16 → 8→4 → 2 → 1 It can be seen that this sequence (starting at 13 and finishing at 1) contains 10 terms. Although it has not been proved yet (Collatz Problem), it is thought that all starting numbers finish at 1. Which starting number, under one million, produces the longest chain? NOTE: Once the chain starts the terms are allowed to go above one million.
You are asked to write a simple interpreter for postfix arithmetic expression (e.g. (xy+) or (xy- qwe+ / g +*)) in Racket. Remember that an interpreter is a program that takes another program to execute / evaluate the contents of it.Feel free to create your own data types, use different data structures to ease your task.
