Exploring Programming Languages

Popular programming languages of the 1970’s: * B – Was a forerunner to “C” * Created by Dennis Ritchie and Ken Thompson at Bell Labs in 1969. * Designed for recursive, non-numeric, machine independent applications, such as system and language software. * C – A general purpose, imperative computer programming language, supporting structured programming. * Was designed by Dennis Ritchie at Bell Labs in 1972. * Used to re-implement the Unix operating system. * Smalltalk – An object oriented, dynamic typed, reflective programming language. * Designed and created in 1972 at the Learning Research Group by Alan Kay, Dan Ingalls, and Adelle Goldberg. * Created as the language to underpin the “new world” of computing exemplified by “human-computer symbiosis.” * Prolog – The first logic programming language. * Designed in 1972 by a group around Alan Colmerauer. * Intended use was for natural language processing. * ML – A statically typed functional programming language. * Designed by Robin Milner in 1973. * Purpose was to develop proof tactics in the LCF theorem prover.

Popular programming languages of the 1980’s: * C++ - General-purpose programming language. Imperative, object-oriented and generic programming features. * Designed by Bjarne Stroustrup at Ben Labs in 1980. * Designed with a bias toward system programming and embedded, resource-constrained and large systems, with performance, efficiency, and flexibility of use. * Ada – A structured, statically typed, imperative, wide spectrum and object-oriented high-level computer programming language. * Originally designed in 1983 by a team led by Jean Ichbiah under contract by the United States Department of Defense. * Intended for use by

...| Exploring Programming Language | Unit 1 Research Assignment 1 | | | 5/3/2014 | PT1420 | The five most popular programming languages in the 1970’s were: 1970: Pascal 1972: C 1972: Smalltalk 1972: Prolog 1973: SQL Pascal The Pascal programming language was developed by Niklaus Wirth. It was created in 1968 but it wasn’t published until 1970. It was developed to provide the features other programming languages didn’t offer at that time. His main reason for developing Pascal was efficiently implement and run, to allow for the development of structured and well organized programs, and to serve as a tool to teach the important concepts of computer programming. The program was named after a mathematician named Blaise Pascal. It was used as the primary language in the Apple Lisa and for the Mac in the early years of the computer. SQL SQL, which is short for, Structured Query Language, was designed by an IBM research center in 1974-1975. The Oracle Corporation introduced it as a commercial database system in 1979, the first time it was introduced. It has been a favorite query language for the use of database management systems for the microcomputer and mainframes, but is being supported by the PC database. C C was created at the Bell Laboratory in 1972 by Dennis Ritchie. It was created for the purpose in designing UNIX. Prolog Was created from 1971-1973 and was distributed in 1974-1975. It was created not as a programming language on purpose but...

Critical Analysis Crime and Media

...Communication Vol 53 no 1, pp 88-104. Topic The theme of this intriguing and thoroughly researched report examines the influence of media consumption on fear of crime, punitive attitudes and perceived police effectiveness. It widely observes the effect that wide reporting and viewing of violent crime has on public knowledge and questions whether the polling data is a reflection of violent crime in America or the television media accounts of it. Context Context refers to the set of surrounding circumstances for any text, piece of research, publication, event etc. Almost every piece of research will have multiple contexts (Study Guide Glossary COM15, 2013, p 94). This journal article portrays the growing insecurities and encroachment that mass media has on our everyday lives, especially its account of violent crime, and how such mediums can impact on the viewer’s account of such events. This journal article has been used and published in a variety of professional and scholarly journals dealing in a range of fields including media and communication, legal and justice studies and behavioural psychology. Structure The paper is in the format of a formal research paper. It is a format that is more objective and non-personal; it’s the methodical process that involves the collection and analysis of information.

Neuro Linguistic Programming-Connector Between Managers and Subordinates

...NLP: CONNECTOR BETWEEN MANAGER AND SUBORDINATE Palwasha Khan Sana Iqbal Sundus Younis Faculty of Engineering Management Center of Advance Studies in Engineering (CASE) Abstract: Neuro Linguistic Programming is thought to be an advance communication tool which incorporates Human cognition, behavioral contour, and unconscious verbal/nonverbal patterns in order to understand the way information is being perceived, processed and acted upon by the individual and how he interact with his environment including the human factor. It is continuously being probed for its impact over successful human interactions and relationship. Usage of NLP in business world is still unexplored in certain aspects. This research paper is meant to study the impact of appropriate NLP techniques over the relationships that typically exist between managers and subordinates. Using a survey questionnaire, data is being collected from employees of a variety of organizations and found out that though mostly, NLP is unconsciously applied in managerial sector, it does play its role in improving the perceived manager-subordinate relationship, through improving the trustworthiness of the managers and the social bonding that exist between the managers and their subordinates. NLP also impacts to a lesser degree upon the feedback process and participative management style of the manager. Currently managers give more credit to importance of NLP techniques in better relationship building than the subordinates....

Structure and Functions of a Computer 1 1.0 Introduction A computer is an electronic machine designed for the storage and processing of data. The machinery is called hardware, and this highly sophisticated equipment needs equally sophisticated programs (called software) to become a working computer system. Modern society has come to depend very heavily on the use of computer systems. Banks, businesses, government departments, industries, shops, people at home and school all rely on computer to play a vital role in their daily activities. These activities are centered on information. In business, the computer system has been used a lot and replaced filing cabinets as means of storing information, and clerical workers as a means of processing it. By storing and processing information on a computer system, these businesses can function more quickly and efficiently, because information can be found and collated much faster.

Riordan Manufacturing Business System Proposal

...Riordan Manufacturing Business System Proposal Paul Belanger, Aaron Ledger, Dacia Faulk, Ian Westerfield, Jennifer Gallaway University of Phoenix Introduction Being the industry leader in polymer materials and per our mission statement, Riordan Manufacturing must remain in step with industry trends. In order to effectively attain this objective, we must acclimatize, embrace, and take advantage of new and innovative technologies. In addition to identifying existing systems employed within the company that are in need of upgrades, the remainder of this paper will also address new systems as well as sub-systems needed and present a brief summary of why these systems would be advantageous to the future of Riordan Manufacturing. Finance and Accounting Overview Riordan manufacturing employs nine basic finance and accounting subsystems globally and three additional subsystems at the San Jose, California corporate headquarters. The atmosphere of interoperability between each of Riordan’s offices (California, Georgia, Michigan, and China) is at best hostile. At present, each operating entity has its own finance and accounting system resulting in a number of inefficiencies due to company-wide systems incompatibility, a lot of which stems from the Michigan and Georgia acquisition. To better establish potential interoperability between existing subsystems, it is first necessary to define the current subsystems of each Riordan office, existing software solutions, and how these...

The Knuth Marris Pratt Algorithm

...Irvine, CA 92697-2625, USA schmidt@uci.edu 1 Overview of Trends, Challenges, and Opportunities Two fundamental trends influence the way we conceive and construct new computing and information systems. The first is that information technology of all forms is becoming highly commoditized i.e., hardware and software artifacts are getting faster, cheaper, and better at a relatively predictable rate. The second is the growing acceptance of a network-centric paradigm, where distributed applications with a range of quality of service (QoS) needs are constructed by integrating separate components connected by various forms of communication services. The nature of this interconnection can range from 1. The very small and tightly coupled, such as avionics mission computing systems to 2. The very large and loosely coupled, such as global telecommunications systems. The interplay of these two trends has yielded new architectural concepts and services embodying layers of middleware. These layers are interposed between applications and commonly available hardware and software infrastructure to make it feasible, easier, and more cost effective to develop and evolve systems using reusable software. Middleware stems from recognizing the need for more advanced and capable support–beyond simple connectivity–to construct effective distributed systems. A significant portion of middleware-oriented R&D activities over the past decade have focused on 1. The identification, evolution, and expansion...
