- The Population Studies Institute monitors the population of the United States. In 2008, this institute wrote a program to create files of the numbers representing populations of the various states, as well as the total population of the United States. This program, which runs on a Motorola processor, projects the population based on various rules, such as the average numbers of births and deaths per year. The institute runs the program and then ships the output files to state agencies so the data values can be used as input into various applications. However, one Pennsylvania agency, running all Intel machines, encountered difficulties, as indicated by the following problem. When the 32-bit unsigned integer 1D2F37E8 (representing the overall U.S. population prediction for 2013) is used as input, and the agency’s program simply outputs this input value, the U.S. population forecast for 2014 is far too large. Can you help this Pennsylvania agency by explaining what might be going wrong?…Computer Science Explain in detail the differences between a General Purpose Applica2on SoNware and a Specific Purpose Applica2on SoNware.

- Assume you have a computer that runs a programme that is 50% floating point multiply, 20% floating point division, and the other 30% is made up of other instructions. a. Management desires that the machine run four times faster. You can speed up the division by no more than three times and the multiply by no more than eight times. Can you accomplish management's target with just one enhancement, and if so, which one? b. What is the speed of the new machine in comparison to the original machine if you enhance both multiply and divide?the available space list of a computer memory is specified as follows: 9 start address block address in words 100 50 200 150 450 600 1200 400 determine the available space list after allocating the space for the stream of requests consisting of the following block sizes: 25,100,250,200,100,150 use i) first fit ii) best fit and iii) worst fit algorithms19) The cost of accomplishing a given amount of computing has been falling steadily due primarily to the cost efficiency of boosting the speed of microprocessor hardware.

- Step 1 Programs are the set of lines of code that is used to provide instructions to the computer. The instructions are provided to perform certain tasks. The instructions are implemented by the programmer using the programming language according to the requirement. The instructions are given by the program accordingly. The program is used to solve everyday problems, it is used for problem-solving. It can be used to solve complex problems in seconds. Examples of binary code are 101 is the representation of 5 in digital, etc. arrow_forward Step 2 The importance of binary code are as follows: Images are most typically created in systems with the help of tiny colored squares known as pixels. Binary codes are used to represent images. In particular, understanding the binary digits of image pixels paves the way to image manipulation applications like trying to hide one image inside the other. For carrying out the instructions, computer programs employ a very specialized logic…Exercise 8 The speed of the connection between a computer’s memory and its processor often determines the speed of the computer, because instructions often can be executed faster than they can be moved to the processor for execution. This connection is called the von Neumann bottleneck; it is the limiting factor in the speed of computers. True or FalseBy assuming that X is the last digit of your student number and 3X is a two digitnumber, consider memory storage of a 64-bit word stored at memory word 3X ina byte-addressable memory(a) What is the byte address of memory word 3X?(b) What are the byte addresses that memory word 3X spans?(c) Draw the number 0xF1234567890ABCDE stored at word 3X in both big-endianand little-endian machines. Clearly label the byte address corresponding to eachdata byte value.
