* Lecture -- concepts of computers
* Lab -- hands on skills, microsoft office

Lecture:
New Perspectives on Computer Concepts, 10th Edition, Comprehensive (New Perspectives Series)

Lab:
Big diff bet Office 2003 and Office 2007
Exploring Microsoft Office 2007 Vol. 1 (3rd Edition) (Spiral-bound)

I-building, help desk

* three lab exams (word - 10%, excel - 25%, access - 25%)
* powerpoint project - 5%
* lecture exam - 10%
* hw - 10%
* web project - 10%
* quizzes - 10%

What do you need to do the lab exercises and lab homeworks?
* data - from prentice hall's website
* programs - Microsoft Ultimate Steal (Professional Academic Edition)

1 point = 1/72"

input
output
memory (RAM)
math ability
control

CPU - central processing unit. contains:
*ALU - arithmetic / logic unit
*control unit

von Neumann architecture

instead of specialized machines
universal computer, general purpose computer

hardware -- physical components
software -- instructions, computer programs

fetch-execute cycle

computer program: a bunch of instructions

1. Say: Please enter a #
2. Get a number, store it in X
3. Say: Please enter another #
4. Get a number, store it in Y
5. Add X and Y, store it in Z
6. Say: X + Y = Z
7. Go to step 1

IP: instruction pointer (within the control unit)

Artificial Intelligence
Alan Turing - Turing test


Don't need to get this, but C++ Express Edition

In C++
// calculator1.cpp : Defines the entry point for the console application.
//

#include "stdafx.h"
#include <iostream>
using namespace std;

int main()
{
    int x, y, z;
beginning:
    cout << "Please enter a #: ";
    cin >> x;
    cout << "Please enter another #: ";
    cin >> y;
    z = x + y;
    cout << x << " + " << y << " = " << z << endl;
    goto beginning;
    return 0;
}


A computer only understands machine language
01000010001
annoying

assembly language
MOV AX, 4
MOV BX, 6
ADD AX, BX
SAY AX

there will be a computer program which takes an assembly language program as input, will spit out the machine language program as output

assembler
disassembler
still annoying

programming languages:
Visual Basic, C++, Java, Javascript, Python, Prolog, Lisp

we need to translate it

Visual basic:
For I = 1 to 10
    Msgbox "Hello there!"
Next

translators:
* compiler
* interpreter

interpreted is slower
you get to send the original plaintext instructions for an interpreted languages

C++ compiled language
Javascript interpreted languages

how do I make a 9 page paper into a 10 page
paper?
* line spacing (multiple and exactly)
* adjust the margins
* increase size of period
* add footnotes and images
* add meaningful text
* font face. fixed width, proportional width
* letter spacing
* widow and orphan protection
