Expert Solution & Answer
Chapter 5, Problem 4RQ
Explanation of Solution
Open source software:
- Open source software is not restricted to any particular
operating system and lets a free access to the computer users to code, run, fix error and improve in it. - Open source software is managed by an international network of programmers and users and its ownership is not restricted to an individual or company.
Linux:
- Linux is an operating system that is compact, reliable in design and can run on multiple hardware platforms varying from servers to electronics.
- It is like UNIX operating system but can be easily available from the Internet without any cost to it...
Explanation of Solution
Java and its importance:
- Java is a popular object-oriented
programming language used for providing a processor independent access to build applications that can run on the web. - It helps users to minimize the time consumed on writing specialized software and enables them to manipulate data on networked systems using web browsers.
HTML5 and its importance:
- HTML or Hypertext markup language is used for creating web pages.
- It a programming language used to detail the text, graphics utilized in a web page and provide dynamic links to outside content from the web page...
Explanation of Solution
Web services:
- Web services are loosely deployed software components that enables different applications of different organizations to integrate and communicate with each other.
- They are not belonging to a particular operating system or language and hence they provide an ability to link various types of systems in a company, in a standard way.
- This standardizes and provides a seamless service for businesses to share their web sites to other external web sites without the necessity for a custom coding operation...
Explanation of Solution
Three external sources for software:
Software packages and enterprise software:
- A software package is commercially available software program that can be purchased to perform certain functions of business operations like payroll processing or invoice management.
- These help to avoid the need for companies to create applications by their own written codes which is time consuming, sometimes beyond their expertise and increased cost.
- Enterprise software is an integrated package that provides a single solution to the needs of a large organization to perform its standard operations.
- These globally deployed system can be purchased on a cost of its developing cost.
Cloud based software services and tools:
- These services provide applications to perform business operations that are located remotely through the Internet or a private network.
- Instead of the IT infrastructure being provided on premises, users utilize these online services for a subscription fee or based on transactions...
Explanation of Solution
Software mashups and apps:
- Mashups are hybrid software applications that are created by combining several applications, however the mashup being of superior value to the user than the original applications. It is a sum greater than the sum of its parts.
- The idea of mashups lets users gain their required need by letting them combine applications and services to result in a new better application.
- Apps are specific portions of a software program that can be used in mobile devices or desktops to perform general computing operations...

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: t₁ to Description 00 Output Relationship Ignored Inputs Addition Mode 2 Coutsjaj + bj + Cin, Tout= 0 Tin 0 1 Shift Left Mode Sj = Cin, Cout=bj, rout = 0 rin, aj 10 1 1 Shift Right…arrow_forwardShow the correct stereochemistry when needed!! mechanism: mechanism: Show the correct stereochemistry when needed!!

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.
