Question 1
The evolution of computer hardware and software has allowed computer systems to become more accessible and user friendly. With computers only being used by programmers in the 1940’s anyone can now successfully operate a computer with very little experience. This evolution has also allowed for more advanced functions that can assist with day to day activities such as scheduling, personal networking, and mobile communications which current generations have become nearly dependent on.
Question 2
Insurance adjusters can now operate more efficiently with mobile computers by being able to generate reports in the field versus having to take notes and doing this once they return to their office, losing time and productivity. They can also wirelessly transmit these reports while in the field from their mobile computers allowing claims to be processed faster improving customer satisfaction. General practitioner doctors can also benefit from mobile computers by only having to carry one device on a cloud network to easily access all patient files in one location. He or she can also use this same mobile computer to wirelessly transmit prescriptions, referrals, or other orders instantly and securely improving patient service and confidentiality.
Question 3
1 Megabit is 1,000,000 bits and 1 Megabyte is also 1,000,000 bytes but they are actually not the same. There are 8 bits within 1 byte and making 1 Megabyte the same as 8 Megabits.

The memory block Job Q is occupying is 45K, 46,080bytes to be exact.
Part C.
The fragmentation is an external fragmentation because the 3k that are remaining, although unusable in its current state, can be compacted with other unused memory. In order for it to be internal fragmentation, by definition, the 3k of unused space would have to be wasted.

Wicken* Department of Biochemistry, Penn State University, Erie, Pennsylvania, USA This paper introduces the new evolutionary paradigm born of the synthesis of Darwinism and thermodynamics. It also introduces this volume, whose theme is the integration of life and social process with physical law. The sense of this expansion is as follows: Darwinism has come under intense scrutiny in recent years, from several fields. These range from statistical mechanics to developmental biology. In this paper, I will discuss the direction the revision of the Darwinian program is taking through thermodynamics, which is the science of irreversible process and self-organization. My objective is to show the coherence of life with the rest of nature. # 1998 John Wiley & Sons, Ltd. Keywords evolution; emergence; thermodynamics INTRODUCTION Evolutionary theory is presently undergoing the kind of massive conceptual restructuring that marked the two great scientific revolutions of our century: relativity and quantum mechanics. Like those two revolutions, the one occurring in evolutionary theory has tremendous practical and epistemological implications for understanding, and dealing with, nature. Much is dissonant in the Darwinian world. The ecological relationality of life had, from the time of Aristotle, suggested a functional order of nature...

Study Pn Evolution of Computer Software

...STUDY ON EVOLUTION OF COMPUTERS STUDY ON EVOLUTION OF SOFTWARE Introduction Computer software, or just software, is any set of machine-readable instructions that directs a computer's processor to perform specific operations. The term is used to contrast with computer hardware; the physical objects carry out the instructions. Hardware and software require each other and neither has any value without the other. The first theory about software was proposed by Alan Turing in his 1935 essay Computable numbers with an application to the Entscheidungsproblem (decision problem). Colloquially, the term is often used to mean application software. In computer science and software engineering, software is all information processed by computer system, programs and data. The academic fields studying software are computer science and software engineering. The types of software include web pages developed in languages and frameworks like PHP, Perl, JSP or ASP.NET and desktop applications like OpenOffice.org, Microsoft Word developed in languages like C, C++, Objective-C, Java, C#, or Smalltalk. Application software usually runs on underlying software operating systems such as Linux or Microsoft Windows. Software (or firmware) is also used in video games and for the configurable parts of the logic systems of automobiles, televisions, and other consumer electronics.

Chapter 1 Introduction to Operations Management

...CHAPTER 1 INTRODUCTION TO OPERATIONS MANAGEMENT KEY IDEAS 1. Three Basic Business Functions. Operations is that part of an organization responsible for the creation of value in the form of goods and/or services, ideally balancing the supply of these items with customer demand. Operations works in conjunction with the complementary business functions of finance, responsible for securing and allocating the financial resources necessary to maintain the organization, and marketing, responsible for evaluating and enhancing customer demand. 2. Input, Output and Value-added. Any operation can be described as a set of inputs (i.e. labor and materials) that are transformed into a set of outputs (i.e. goods and/or services), as illustrated in Figure 1.4 of page 6 of the textbook. The essence of operations management is value-added, or the degree to which the value of all outputs of an operation exceed the value of its inputs. 3. Goods vs. Services. Goods imply tangible products, those that can handled and/or stored in some fashion, such as manufactured items or food. Services are intangible products, such as health care or education. Material goods often require a distribution system to get them into the hands of consumers, while service industries tend to deal directly with consumers. Other important points on which the production of goods and services differ are summarized in Table 1.3 on page 9 of the textbook. 4. Process Management. A process is any action involved...

Motivations and Evolution Since the evolution of hacking, the skills and creativity of hackers have matured and the motivation behind hacking has been revolutionized from the origins to its current form.

Subsequently, numerous hackers did not seem satisfied with the benign exploration of computer systems simply to learn about their internal operations as the hackers were now interested in individual gains (Clarke, Clawson & Cordell, 2003).

Fuller CMGT 556 Dr. Manuel Torres September 9, 2012 The Evolution of Enterprise Resource Planning (ERP) was developed to distribute computerized automation to several different entities of an organization to assist with problems of handling raw materials, inventory, order/data entry, and distribution. Before the evolution of ERP it was not possible for many of the functions in the past such as sales, marketing, and shipping to be done. It was impossible to integrate ERP with the capabilities of CRM whereas organizations would be able to use customer specific information to tie into a web portal for order services between a customer and a business. Integration between ERP and CRM was impossible during its earlier development. The evolution of ERP has developed into a comprehensive software activity that has extended its reach to encompass warehouses, distribution, and order/data entry.
