...Unit 1 Research 1 PT1420 In the 1970s the programming language that was most popular was Pascal. Pascal was designed in 1968-69 but published in 1970. Niklaus Wirth created the Pascal language to “1) make available a language suitable for teaching programming as a systematic discipline based on fundamental concepts clearly by the language, and 2) to define a language whose implementations could be both reliable and efficient on then-available computers. In 1972 the C programming language was developed by Dennis Ritchie. C was created to work with the system Unix. “Unix gives C such advanced features as dynamic variables, multitasking, interrupt handling, forking, and strong, low-level, input-output. Because of this, C is very commonly used to program operating systems such as Unix, Windows, the MacOS, and Linux.” In the 1980s the popular programming language was C++. C++ was developed at Bell Laboratories. C++ is a general purpose multi-paradigm spanning compiled language that has both high-level and low-level languages’ features. It was started as an enhancement to the C programming language, Bjarne Stroustrup in 1979. In the 1990s Java was the popular programming language. It was created in 1991 developed by James Gosling at Sun Microsystems and release in 1995. In the 2000s Visual Basic (VB) was popular in the programming world. VB was developed from BASIC which was originally developed in 1964 by John Kemeny and Thomas Kurts. VB is a Microsoft programing language and software...

...Describe the role of software for computers Software is everything we do with computers. If there was no software on a pc then it would just sit there and do nothing because nothing is telling what to do. Software is your word processor or your internet browser, we use software every day and don’t even realize it. Identify the hardware associated with a computer CPU-central processing unit RAM-Random access memory HDD-Hard Drive MOBO-Motherboard PSU-Power Supply Unit Describe how computers store data The data can be written to 2 different places. It can put into the RAM for fast but expensive storage, as it can be used up very quickly. It can also be put on the HDD for your long term storage. When the data gets written to the HDD its put on to platters that are within the HDD. When it’s stored in the RAM its put on to the flash memory chips on the side of the RAM. Explain how programs work. Programs work like recipes as they tell the pc exactly what to do and how to do it. But it doesn’t just do this it needs a user’s input so that it can then decide what recipe to use. Every program has to have a recipe for any action that the program will do. Differentiate among machine language, assembly language, and high-level languages Machine language- is a series of 1,0 that is a instruction set for the CPU to process. Assembly Language- is short abbreviations for code, like add typically means to add, mul means to multiply. High-level language- simplifies...

...| 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...

...Michael Campbell PT1420 Unit 1 Re Ass 1 10/10/2014 1. 1970s – The programming language was C, which was created by Dennis M. Richie. Before he created the C language there was the B language, which was created by Ken Thompson in 1969-70. The computers in that time wrote in assembly code and the user had to write many pages of code to do a task. When the B language was created, it made it possible to do a task in a few lines. Although the B language improved the systems it lacked use of structure and didn’t know data types. So in 1971-73 Dennis Richie wrote the C language in which he kept the B syntax but added data types and other changes that needed to be made. It was built for power and speed and developed for UNIX systems. Its also used for Windows, the MacOS and Linux. 2. 1980s – The programming language was Python, which was created by Guido van Rossum. It’s more of a scripting language and allows users to produce large quantities readable and functional code in a quick amount of time. Python teaches the user how to work with other languages, indentation, and modularity. It supports object – oriented, procedural, and functional program styles. C++ was also created and used many different types of computers. Program A was created by Arthur Whitney in 1988, and it focused on graphics, systems interfaces, utility support, and user community. 3. 1990s – The programming language was Ruby, which was created by computer scientist Yukihiro Matsumoto. It was created...

...the following equation. This equation shows that the rate of change of the human population can be expressed by minus the population of zombies. Consequently, this new model predicts that the zombie population will grow exponentially. It is possible to use this equation to find out how quickly the human population is changing for any number of zombies. For example, if there are 50 zombies, the rate of change of the human population can be expressed by the following. This shows that the rate of change of the human population when there are 50 zombies is -50. This means at this time, the human population will be shrinking at a rate of 50 humans per day. Assuming the population of zombies can be expressed by the equation in kill rate 1, the following substitution can be made. Therefore, it is possible to integrate the equation to find the population of humans over time. It is possible to calculate the value of A by finding the initial conditions. When time is 0, it has already been stated that there are 9999 humans. Therefore, these values can be substituted into the equation and it rearranged for A. Therefore, the population of humans can be modelled by the following equation. Thus, the population of zombies is modelled by, . Both of these can be graphed as follows. Figure 2. Populations of both zombies and humans over time. Using figure 2, it can be seen that the time that it takes the zombies to overtake the human population has drastically decreased...

...Larry Smith March 28, 2015 PT1420 Week 1 assignment COBOL, is a compiled English-like computer programming language designed for business use. It is imperative, procedural and, since 2002, object-oriented. COBOL is primarily used in business, finance, and administrative systems for companies and governments. In 1997, Gartner Group estimated that there were a total of 200 billion lines of COBOL in existence, which ran 80% of all business programs. COBOL is still widely used in legacy applications deployed on mainframe computers, such as large-scale batch and transaction processing jobs. But due to its declining popularity and the retirement of experienced COBOL programmers, programs are being migrated to new platforms, rewritten in modern languages or replaced with software packages. Most programming in COBOL is now purely to maintain existing applications. COBOL was designed in 1959 by the Conference on Data Systems Languages (CODASYL) and was largely based on previous programming language design work by Grace Hopper, commonly referred to as "the (grand)mother of COBOL". It was created as part of a US Department of Defense effort to create a portable programming language for data processing. Intended as a temporary stopgap, the Department of Defense promptly forced computer manufacturers to provide it, resulting in its widespread adoption. It was standardized in 1968 and has since been revised four times. Expansions include support for structured and object-oriented programming...

...In the beginning of the semester I had many questions that I wanted to answer to my inquiry question, now I have all the answers. I learned so much about bilingual students that I would have nerve thought I would have learned. I learned that the teachers often are supporting students as young writers with read aloud in classrooms, side by side work with doing written activity and share time. In my inquiry project I did a lot of reading aloud and activities that included writing. I notice that I help support the student as a young writer with all my activities and read aloud. Also the read aloud was the best way to support my student because there’s listening, thinking and conversation as I read. Author Judith and Collins emphasize that book reading and conversation support the development of oral language and content knowledge. I learned that the students were able to use literacy to express their emotions. My student was able to express her emotions verbally and through drawing. Schickedanz and Collins (2013) ,”Children typically set out to draw with intention, and they use details that help convey their meaning. I learned that through literacy, children able to learn about how to express their emotions and regulate their behaviors.

...The rhetoric refers to techniques to persuade the audience. When considering the rhetorical situation the first thing I consider is who is my audience? What does the audience already know? What does my audience care about? You have to find how I am going to communicate my message to the audience. Making sure that I convey a proper way to persuade the reader. After selecting a topic I need to think about specific questions I want to address in my research questions. I ask myself do I want my question to be clear, focused, or complex. The research questions are going to help focus on a broad topic and specific issue to help develop search terms for my research. Identifying research questions by selecting nouns important to the meaning of your questions and leaving out ones that don’t help. Concept mapping helps refine your questions as you focus on your topic. Using strategic searching to find answers to my topic, I need to find appropriate research questions. Why does this topic matter to me? Why should it matter to others? My research question should not have a simple yes or no answer but require research and analysis.
