Please use the Java Programming language. This is the introductory course, chapter two. Please only use if/else if, else and while loop. We have not touch base with do and while do(I don't know if while do exist in Java).

Create an application that converts number grades to letter grades.

Console

Welcome to the Letter Grade Converter

Enter numerical grade: 90

Letter grade: A

Continue? (y/n): y

Enter numerical grade: 88

Letter grade: A

Continue? (y/n): y

Enter numerical grade: 80

Letter grade: B

Continue? (y/n): y

Enter numerical grade: 67

Letter grade: C

Continue? (y/n): y

Enter numerical grade: 59

Letter grade: F Continue? (y/n): n

Specifications • The grading criteria is as follows: A 88-100 B 80-87 C 67-79 D 60-67 F <60 • Assume that the user will enter valid integers between 1 and 100 for the grades. • The application should continue only if the user enters “y” or “Y” to continue.

Convert -18 to 8-bit sign magnitude, 1's complement and 2's complement.

Create your own function in Java that accepts one input parameter and returns a float number. You decide the theme.

What are the necessary requirements for an Electronic document Management System (EDMS) that will integrate five stores and consistently retain and securely manage critical business documents in the following areas

• Major components that must be included in a document retention policy

• Policies standards, and procedures that will govern the secure management of the organization’s critical business documents

• Regulatory requirements and generally accepted practices that are applicable to the organization to safeguard its data

• A list of Hollywood Organic Co-op's stakeholders and their responsibilities • A recommended framework for a document life cycle

• At least two examples of an enterprise tool available on the market that could be incorporated into the organization to integrate the EDMS across the various store locations

What are the best practices, applicable standards, and types of policies that govern a document management life cycle for implementing an enterprise EDMS.

Convert -18 to 8-bit sign magnitude, 1's complement and 2's complement.

Written in C code:

Using a structure called person, write a C function called compare_age that takes two person structure pointers as input and returns 1 if the first person is older, -1 if the second person is older, or 0 if they have exactly the same birthday. Hint: Compare the years first, then if equal compare months, if they are equal compare days.

The structure called person should contain the following; has fields for name (50 char array), dateOfBirth (structure called date that has three fields day, month, year, all of which are ints.), address (200 char array), phoneNum (20 char array), and ID (int).

You should print out the comparison result of whether person 1 or 2 is older or if they have the same age.

1. An assembler translates assembly language to machine language instructions. A disassembler can be used to translate the other way, from machine language to assembly language. For example, our 8086 emulator shows both the machine language bytes and the disassembler output while running a program (it also shows the original assembly code). The disassembled code is usually harder to read than the original assembly language program because some things are missing or may be incorrect. Write down one of the things that may be missing or incorrect

- can you explain how the Kasiski’s method work in determining the key length from the observed Vigenere cipher.

5. AAA Medical Devices is a manufacturer of portable and wearable medical monitoring devices. They have developed a glucose monitor embedded in a wristband. The device is powered by body heat and senses glucose levels from minute quantities of perspiration. AAA wants to develop a Real-Time Glucose Monitoring (RTGM) system which will be using this device. AAA is planning to see the software to other health systems worldwide.

The software should be accessible on smartphones with Bluetooth capability.

The project has commenced, and you are appointed as a Systems Analyst to understand the requirements of the new system.

Think about the potential users of the system and discuss three fact-finding techniques that you would use to collect the requirements of the new system.
