Chapter 5, Problem 5.21MML
Explanation of Solution
Purpose of the
- The main purpose of the database is keeping track of the things.
- It is tool that is used to organize large amount of data.
- It is used in storing and transforming the data into information that can be used in supporting decision making.
Choice of database when preferred with spreadsheets:
- Generally spreadsheets are also used to track things, the circumstance where a database is preferred with spreadsheets are when more information needs to processed to obtain a certain decision.
- Spreadsheets are limited when more details regarding the data collected needs to be added.
- In that case, database are preferred when more data needs to be added to calculate.
Determining database as a better choice:
Managing hundreds of spreadsheet with huge amount of data is really a tedious process for the manager.
- The data that are present in the spreadsheet can be used in an effective way with the help of queries.
- The data contents that are present in the database are processed based on the query, can be protected from the malicious user and data gets stored permanently into the database and the chance of data being lost gets reduced.
Therefore, the choice of using database is recommended in the solving the problems stated.
Developing the database as a centralized database:
Centralized database is a database that stores the data which can be maintained at a single location. Thus, when creating a database as a centralized database it provides the following advantages that are listed below:
- It helps the data that are stored being maintained in consistent way thus ensuring the reliability of the data.
- It provides security to the data that are stored...

1 An Extended Full Adder
In this Section, we are going to design an extended full adder circuit (EFA). That EFA takes 6 one bit inputs: aj, bj,
Cin, Tin, t₁ and to. Depending on the four possible combinations of values on t₁ and to, the EFA produces 3 one bit
outputs: sj, Cout and rout.
The EFA can be specified in principle by a truth table with 26 = 64 entries and 3 outputs. However, as the EFA
ignores certain inputs in certain cases, it is easier to work with the following overview specification, depending only
on t₁ and to in the first place:

Write a C program that is passed a virtual address (in decimal) on the command line and have it output the page number and offset for the given address. As an example, your program would run as follows: ./addresses 19986 Your program would output: The address 19986 contains: page number = 4 offset = 3602 Writing this program will require using the appropriate data type to store 32 bits. We encourage you to use unsigned data types as well. Programming Projects Contiguous Memory Allocation In Section 9.2, we presented different algorithms for contiguous memory allo- cation. This project will involve managing a contiguous region of memory of size MAX where addresses may range from 0 ... MAX - 1. Your program must respond to four different requests: 1.
