Which of the following is true about the process of read data, as described in the chapter? a. The CPU tells the RAM which address holds the data that the CPU wants to read. 6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1.
Unit 1 Assignment 1 PT1420T Walter Kobylak Learning Objectives and Outcomes * Describe the role of software for computers. Software programs are used for performing functions with a computer. * Identify the hardware associated with a computer. Motherboard, CPU, Processor, hard drive or internal storage device, graphics adapter, keyboard, mouse. * Describe how computers store data.
The CPU tells the RAM which address holds the data that the CPU wants to read 6. A user has opened a word processor, typed the numbers 123456789, and stored the document as a file called report1. Which of the following determines, in part, what bits the computer stores in the file to represent the typed into the report? C. Character set 7. A user has opened a calculator application, typed the numbers 123456789, and then done some math problem using this number.
Input/ output channel from transferring data Homework -What are three main purposes and operating system? User interfaces / manages hardware / design to apps What are the main differences between operating systems for mainframe computers and personal computers? The number of users List the four steps that are necessary to run a program on completely dedicated machines- a computer that is running only that program. Machine time, load address, and execute address, module apps We have stressed the need for operating systems to make efficient use of the computing hardware. When is it appropriate for the operating system to forsake this principle and to “waste” resources?

1. Why is all data stored in a Computer in binary form? Because computers only understand the binary numbers. (0, 1) 2. What are the four primary functions of hardware?
Michael Knall Date: 6/26/14 Class: Programming Unit 2 Assignment 1: Homework Short Answer 1-4: 1.) What dose a professional programmer usually do first to gain an understanding of a problem? Break the larger problem into independent sub-problems. Seek solution of each sub-problem. Test the solutions of each sub-problem.
This has led to a plethora of more or less standardized file structures for all imaginable purposes, from the simplest to the most complex. Most computer files are used by computer programs which create, modify or delete the files for their own use on an as-needed basis. The programmers who create the programs decide what files are needed, how they are to be used and (often) their names. Explain how an operating system manages multiple processes… Memory management is the function of a computer operating system responsible for managing the computer's primary memory. The memory management function keeps track of the status of each memory location, either allocated or free.
Assignment 1: Computer Architecture Professor David Moore Course Title: CIS 106: Introduction to Technology 4 May 2014 ------------ Assignment 1: Computer Architecture In the field of computers, advances could be countered on one hand. Von Neumann, a mathematician, had an idea to utilize stored memory in the CPU ( Chapman, 1995). The von Neumann architecture goes back to the original computers intended to undertake precise instructions, and is the first written account of how computers should store programs and process data. In 1945, von Neumann published a report on the EDVAC (Electronic Discrete Variable Automatic Computer) in which he outlined his design for the first stored-program computer. In the days of the initial electronic computing, software design was tantamount with joining wires to plugs.
