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 assembly language, if you wanted to show a message then the code would just be Display “Hello”
Differentiate between compilers and interpreters
Compilers takes high level language program into machine language. So it take the coding that you just finished and complies it and translates it into binary.
Interpreters do the same as the compilers except they take the binary that they just

...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.

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. Also I can use synonyms to help expand my search. That will give me a wide range or define my search to just the words I want to search within the database.

...In the beginning of my research, I started off by going to the UCSB library homepage and clicked on the advanced search catalog. After selecting the advanced search button, I brainstormed key words for my topic. I selected the words combat* or counter and effect* or result* or consequence* or outcome* and “global warming*” or “climate change*”. The first time I put this information into the search engine I got zero results because I carelessly left out the end quote in the word global warming. After I fixed my mistake, I got a total of 37 results. I then proceeded to briefly look over book titles that seemed relevant to my topic to deduce which books to select for my assignment. Subsequently, I researched for the scholarly journal articles by going to the Academic Search Complete database. I used the advanced search engine and selected only peer reviewed journal articles, in English. When inserting the same keywords I used in my previous search, I attained 914 results. To...

...In this assignment, we will be analysing the system of Figueroa’s Framework and how it is incorporated within Lifesaving. Lifesaving is massive in Australia because of the vast number of beaches in this country. Lifesavers greatly contributes to the Australian culture by keeping people safe in the surf. There are three main levels of Figueroa’s Framework which are the Cultural, Interpersonal and Individual levels. These all have great effects on different people throughout the sport of Lifesaving. We will also be assessing a personal analysis with my experience of the Interpersonal level within Lifesaving. Personal Reflection Lifesaving has been a completely new experience for me. I’d never tried it before and non-casual swimming is not really my forte so I did struggle a little bit through it all. One massive thing that helped me get through it, it particular the 300m swim, was the mutual motivation between Blake and me; and this is where the interpersonal level of Figueroa’s Framework affects this activity. This extra level of motivation and encouragement from a friend really helps to finish, no matter how your body feels. I was having struggles with the 300m swim because I’m not a great swimmer. I am capable of swimming but have never done it at a level where I had to do it in...

...At the start of this assignment I felt pretty certain in what answers I gave on the paper, or at least that I had gotten the numbers pretty close to accurate. However, after the real data had been given out I realized that I had in fact not been accurate. On the male to female ratio I guessed 52 males to 48 females, which ended up being the one section I was most accurate about. Ever other section had been relatively far from what I had assumed, in world geography my numbers looked like this: 27 Asians, 24 Africans, 16 Europeans, 20 Latin Americans and 13 North Americans. The actual numbers looked very different, and were a lot less spread out between the different groups. I think I can attribute this error to my lack of knowledge on the geography of our world, and not knowing how big or small a country is, but beyond that, not knowing how heavily or little populated a place is....

...The new scoring system has a dramatic change and is potentially game changing, as the scores will escalate by increasing the amount of corners and decreasing the amount of goals. My investigations that are displayed in the tables above have shown all the scores that are possible under 50. Table 1 illustrates all the possible scores if a team were to only get goals; table 2 shows all the possible scores if the teams were only to get corners and table 3 shows all other possible scores of goals and corners. Table 1 demonstrates all the multiples of 8 as each goal represents 8 points and this is the same for table 2 although is all the multiples of 3 that are less than 50. From each of these tables I have found that there are only 9 impossible scores. I gathered that 1,2,4,5,7,10,13,34 and 37 are all scores that are less than 50 and are not possible due to the goals and corners not adding up to these numbers. For example, scoring a corner is 3 points and therefore 1 and 2 are impossible. Another impossible score is 7 as 2 corners=6 and added another corner= 9 so therefore 7 is impossible but 8 is possible as they could score one goal which equals 8. Furthermore, you couldn’t get a score of 4 due to:...

...Scenario 6 Additionally, in order to calculate the probability that exactly 1 marriage will be in the stock, one would apply the same formula as before. Since the stock is composed only of three cards, there could only be 1 marriage. There are 22 possible cards to receive (n) which are not a marriage since there can only be 1 other card (r). It doesn't matter whether the other card would be a pair card or not since it couldn't be a marriage by itself. There are four diverse marriages which means there could be four various marriages with 1 different card from the 22 other cards. This probability is extraordinarily low. It's the lowest probability of all. From my personal experience playing this game, it seems to be true, however, in an actual game the fact that players get cards one by one and not in a row, alters the probability and decreases it even more. The probability of getting exactly 1 marriage in the stock is exceedingly low itself. Rarely does it happen, that there is a pair in the stock which supports this calculation....
